e) Correct any defects within the date of expiry and have no incidents of bond action (an incident of
   bond action will result in the immediate loss of status).
How does it work?
a) Beginning January 1, 2018, contractors will have their history tracked to verify that all criteria have
   been met;
b) Successful contractors will be notified that they have achieved registered contractor status;
c) Once a contractor has reached registered status, the 10% rebate is applied to all permits starting the
   following February; and
d) Contractors will be required to meet the criteria annually to remain a registered contractor and will
   continue to have their history tracked.
NOTE: Use of the TSASK Logo for this purpose is strictly prohibited.

             b. The application and payment may be returned to the contractor to update missing or
                inaccurate information. A fine (as per the Electrical Fee Schedule) for unreported work as
                per The Electrical Inspection Regulations may be assessed for any work that is not
                authorized by a valid permit.

         Section 16 of The Electrical Inspection Act, 1993 and Section 7 of The Electrical Inspection
         Regulations specifies that all permit applications must be accompanied by the appropriate fee.


    Commencement of work
Δ   In accordance with Section 10 of the Electrical Inspection Regulations:
         1. Work for which a permit is granted must be started within 90 days after the date of issuance.
         2. If work authorized by a permit is not started within this time frame, the permit expires at the
            end of that period.
            • Permits may be cancelled by the contractor if work has not been started within 90 days and
                a refund will be issued; administration fees may apply to the refund.
            • If a permit is over 90 days old and less than one year, and work has not been started, the
                permit may be cancelled; and a refund issued (less applicable administration fees).
            • Permits over one year will not be refunded.


    Permit expiry date
    Permits shall expire one year after the issuance of a permit. Permits shall continue to be valid beyond
②   one year by special permission. Supplemental permits must be submitted within 1 year of the permit
    issue date. After that time, a new permit must be obtained.

    each distinct site is located. Where there are multiple disconnects in one location; controllers must be
    labelled as to what they control and where they are fed from, and all underground cables must be
    labelled where they are fed from, or feed to. See Oil & Gas Code 19-052(4).

    1)(n) Farmyards, much like oil wells and irrigation, have potential for complexity in underground
    feeders/services installation. As such, cable labelling is required for underground cables leaving F-
    cabinets and splitters. Labelling should indicate which building or equipment the cabling feeds.

②   3) When using an oversized VFD and wanting to use a smaller feeder to the VFD, it must have a
    disconnect with proper overcurrent to protect the feeder cable. The documentation of the motor must
    be accessible at the VFD and updated when the motor is changed.

    4) Where feeders or branch circuits are added, removed, or modified at an existing panelboard, the
    existing panel schedule and labelling shall be updated with the information as per 2-100 Subrule 3).

2-106 – REBUILT EQUIPMENT
Retrofit kits and installation requirements
With the application of energy efficiency programs in Saskatchewan, high efficiency lighting
technologies and various lighting retrofit kits are popular. There are several options for retrofitting
standard tubular fluorescent luminaries, with more energy efficient lamps.
The retrofit of luminaries and signs may be accepted under the original certification when the following
conditions apply:
     •   The work is covered by an electrical permit;
     •   The replacement equipment bears the mark of a recognized certification agency; or
     •   The replacement equipment is rated for the application and draws no more power than the
         original equipment.
Please note that in all cases, each retrofitted luminaire or sign must be provided with a label containing
the following information:
    • Voltage;
    • Amperage;
    • Date of install;
    • Installed by (contractor name);
    • Permit number, and
    • Over 150 V to ground on the socket for double ended lamps, a label shall be installed stating,
         Caution - De-energize prior to changing tubes.
Some retrofit options are:
     •   Fluorescent retrofit kit – consists of fluorescent tube and electronic ballast that is an integral
         part of the device.
     •   LED retrofit kit – consists of an LED retrofit tube and the LED driver components that are remote
         from (not an integral part of) the device.
     •   LED retrofit kit with integral driver – consists of an LED tube and the LED driver components that
         are an integral part of the device.
Retrofit kits specified above require a luminaire conversion and usually involve replacing the lamp,
rewiring the luminaire and in some cases, replacing an existing ballast with an LED driver, or directly
connecting the lamp to the supply circuit.
Although there are differences in installation of various retrofit kits, for all of them it is very important to
consider that the retrofit kits are certified as assemblies to appropriate Canadian standard(s).
Hazardous location luminaires
Hazardous location luminaire certifications investigate all components to ensure they are not or will not
become an ignition source. Electrical Inspections requires that hazardous location luminaire retrofit kits
be certified to the appropriate standard.
Field modifications to hazardous location luminaires including internal wiring re-work bypassing existing
ballast and wiring directly to the socket with phase voltage, shall be field certified by an approved
certification body.

    SECTION 6 – SERVICES AND SERVICE EQUIPMENT

    6-104 – NUMBER OF CONSUMER’S SERVICES PERMITTED IN OR ON A BUILDING
    The maximum number of consumer services from a single supply service is four. The contractor must
    confirm the installation with the local utility and meet utility requirements prior to construction.
    NOTE: If two supply services are permitted, then they will require a label at each service, stating that
          there are two services and the location of each.


    6-112 – SUPPORT FOR THE ATTACHMENT OF OVERHEAD SUPPLY OR CONSUMER’S
    SERVICE CONDUCTORS OR CABLES (see Appendix B)
    6-112(3) - For the purpose of this rule ‘ground normally accessible to pedestrians’ includes patios and
    decks.
    6-112(5) Appendix B - note states (as per CSA 22.2 No.82) an acceptable manner for mast support is one
    where three (3) support clamps are used, of these, the upper most is required to be a complete
    through-bolt assembly consisting of a minimum 12 mm bolt, nut, and washer, and an insulated point of
    connection.
    As an alternative to the “through-bolt” requirement, with the permission of the Local Electrical
    Inspector, a unistrut support may be allowed to be lag bolted to the exterior of the building (into
    structural members) for mast support. A rigid 2-hole strap and spring nuts shall be used on the mast to
    secure it to the unistrut. This may be allowed on a case-by-case basis, after review and acceptance by
    the Local Electrical Inspector. It should only be considered when it is impractical or impossible to install
    the normal through-bolt support. Must be an insulated point of connection.

Δ   6-200 – SERVICE EQUIPMENT – MANDATORY INSPECTION
    Service inspection requests are mandatory prior to being energized. To facilitate the safe installation of
    services, the contractor is required to arrange an inspection of all services prior to being energized.
    Contractors shall write the permit number in a permanent and visible location inside the meter socket.
    Contractors shall attach a picture of the service (meter socket interior, panel, etc.) to their permit as
    well. Please contact your local Inspector prior to proceeding to the energization request.

    Note: Without Inspector contact and/or picture prior to energization, the Inspections Department will
    reserve the right to demand the contractor arrange an inspection. An administrative penalty may be
    applied. (see 2-012)

6-300 – INSTALLATION OF UNDERGROUND CONSUMER’S SERVICE CONDUCTORS
Caution must be taken by the electrical contractor when installing a customer-owned underground
service from the meter socket to the panelboard location.
The consumer’s underground cable must be installed tight to the basement wall anywhere within 1.5 m
of the meter socket location. This will help to prevent the cable from being damaged when the utility
trenches in their underground service cable from the pole or pedestal to the socket. Once the cable is
past the 1.5 m distance, it may then be installed out away from the basement wall. Cables without
mechanical protection shall be in 150mm of sand or in a conduit to protect it from damage and settling
during back fill.

    SECTION 8 – CIRCUIT LOADING AND DEMAND FACTORS
Δ   8-102 – VOLTAGE DROP
    Precautions must be taken to prevent any services or branch circuits from exceeding 5% voltage drop
    from the utility to the end use, with no feeder or branch circuit exceeding 3%. The calculation of voltage
    drop on services and branch circuits is based on the connected load, or 80% of the overcurrent device
    for unknown loads. See CEC Rule 8-102, Table D-3 and Handbook for clarification and examples.

    Voltage Drop Calculators (apps or websites) may be acceptable for deriving calculations however it is the
    sole discretion of the local Electrical Inspector if they agree with the numbers provided and have the
    ability to request evidence as they see fit.

    Table D3 has been modified, including having the formula for voltage drop calculation displayed 4 ways
    so one does not have to worry about performing the formula permutation as in the past.

    For conductor operating temperatures of 75°C:

         1) Voltage drop for a known conductor size can be calculated from the Table using the following
            formula:
                    VD=(K x f x I x L)/1000

         2)    When the conductor size is not known, the maximum K factor can be calculated using the
              following formula:
                      K≤(VD x 1000)/(I x L x f)

         3)    When the conductor size is known, the maximum cable length can be calculated using the
              following formula:
                      L≤((VD x 1000)/(I x K x f))

         4) The percent voltage drop, VD%, is calculated using the following formula:
                   VD%=(VD/V) x 100

    Where:
    V = connected load voltage at source
    VD = voltage difference between the source and the load expressed in volts
    K = Table voltage drop factor in ohms per circuit kilometre
    f = voltage drop factor based on the electrical system and circuit identified in the Voltage Drop Factor
    Table
    I = load current, A
    L = length of the circuit conductors, m

    Notes:
    The voltage drop factor (f above) must be obtained from the Table in note 2) that accompanies Table
    D3.
    To determine the voltage drop for conductors having 60 °C and 90 °C operating temperatures, multiply
    the K value by 0.95 and 1.05, respectively.

Be sure to review and utilize all the notes for Table D3 as required.

Table D4 has been removed: the ability to perform voltage drop for DC circuits is included in the
material in Table D3.

8-104 – MAXIMUM CIRCUIT LOADING (see Appendix B)
     1. Where single conductor cables are used, they are permitted to be smaller in size due to the
        installation methods. Where they rise to terminate on a breaker, the heating in the enclosure
        can exceed the rating of the conductor. This is the reason that the single conductor cables need
        to be derated further.
     2. Where a fused switch or circuit breaker is marked for continuous operation at 80% or 100% the
        rating of the respective cables will also change as per the CEC requirements. The continuous
        load as determined from the calculated load shall not exceed the continuous operation marking
        on the fused switch or circuit breaker. The continuous load may however be less due to the
        allowable ampacities of the conductors and the deration required by this rule.
     3. Where the maximum continuous load allowed on a fused switch or circuit breaker as
        determined from Rule 8-104 (5) & (6) is less than the continuous operating marking of the fused
        switch or circuit breaker, a permanent, legible caution label shall be installed adjacent to the
        fused switch or circuit breaker to indicate the maximum continuous load permitted.
     4. Installation or addition of a vehicle charging system shall not exceed the building feeder or
        service loading requirements. See also 8-500 (2).

Labels shall be in accordance with 2-100.
8-104(3)(a) – Water heaters
Water heaters are considered continuous loads and, therefore, the circuit conductor and the
overcurrent device shall be loaded to a maximum of 80%. Example - if the water heater is rated at 3000
watts on 240 V (12.5 A), 62-114(7) will allow a #14 AWG conductor and a 20 A breaker.

    8-106 – USE OF DEMAND FACTORS
    8-106(10) is to be used where electric vehicle supply equipment loads are controlled by an electric
    vehicle energy management system (EVEMS).
    8-106(11) is to be used where the system monitors the service and feeders and controls the electric
    vehicle supply equipment loads in accordance with 8-500. Then the demand load for the electric vehicle

SECTION 10 – GROUNDING AND BONDING

10-000 – SCOPE
Grounding and bonding installations shall conform to the drawings provided by the Electrical Inspections
department Interpretations Figures 10-1 to 10-8. The Appendix B drawings may be followed with special
permission.

10-004 – SPECIAL TERMINOLOGY
     •   Equipotentiality — the state in which conductive parts are at a substantially equal electric
         potential.
     •   Grounding — a permanent and continuous conductive path to the earth with sufficient ampacity
         to carry any fault current liable to be imposed on it, and of a sufficiently low impedance to limit
         the voltage rise above ground and to facilitate the operation of the protective devices in the
         circuit.
     •   Bonding — a low impedance path obtained by permanently joining all non-current-carrying
         metal parts to ensure electrical continuity and having the capacity to conduct safely any current
         likely to be imposed on it.
     •   Grounded conductor — in an electrical system, the conductor that is intentionally grounded.
     •   System bonding jumper — a connection between the point of an electrical system to be solidly
         grounded and the non-current-carrying conductive parts of that electrical system.
     •   Single point system grounding – is the connection of the system neutral or grounded system
         conductor to a ground electrode at one point only. This connection shall be made as close to the
         source as possible.



10-100 & 10-500 – CURRENT OVER GROUNDING AND BONDING CONDUCTORS
For the purposes of Rules 10-100 & 10-500, the term ‘objectionable passage of current’ shall be defined
as “any current that flows over conductors for which they were not intended and/or designed to
accommodate, such as neutral current over bonding and/or grounding conductors, or neutral current
over metallic piping”. Caution shall be exercised to prevent this situation from occurring.

Municipal water line replacement programs
Where municipalities are upgrading the water systems, any neutral currents flowing on the water lines
from faulty system grounding may result in a shock hazard. All residences fed from any transformers
showing signs of neutral current on the water lines, need to have their utility systems checked,
grounding systems upgraded and repaired to create a safe installation prior to water line replacement.

    10-102 – GROUNDING ELECTRODES
    Underground metallic water lines shall not be used as a grounding electrode. Any existing ground
    connection to the water line shall be removed when upgrading services. A tag stating ‘WARNING
    POSSIBLE SHOCK HAZARD’ shall be installed at the water meter. Please contact your Local Inspector for
    tags as required. See Figure 10-1:

    10-210 – GROUNDING CONNECTIONS FOR SOLIDLY GROUNDED AC SYSTEMS
    SUPPLIED BY THE SUPPLY AUTHORITY (see Appendix B)
    1) To meet the intent of 10-002 in establishing equipotentiality between bonded equipment and the
       nearby surfaces of the earth, there shall be an electrode installed and grounding conductor
       connected to the non-current carrying parts of electrical equipment at all facilities, buildings, or
       structures supplied with electrical panels or sub-panels. See Figure 10-2.
    2) Customer owned service conductors supplied and installed by the electrical contractor shall include
       a separate neutral, where required, and bonding conductors.. The neutral conductor, where
       required, shall be insulated, and remain isolated beyond the connection to the source. See Figure
       10-2.
    3) Where separate neutral and bonding conductors are not installed, the neutral/grounded system
       conductor shall be connected to ground either directly to the facility electrode or through the
       system bonding jumper. This connection shall be made at the first point of attachment or
       connection of the supply service conductors.
    4) This connection shall be made at only one point and the neutral conductor shall be insulated and
       isolated from the grounding & bonding systems, metallic equipment, and metallic surfaces beyond
       this connection. See Figure 10-4, 10-5 & 10-5a.

5) For overhead services, the neutral conductor shall be insulated, and the grounding connection shall
   be made at the meter socket. Point of connection shall be insulated. See Figure 10-4.
6) Where a neutral conductor is not required (there are no neutral loads being served), a bonding
   conductor shall be installed to facilitate the fault return. The supply authority may require a neutral
   conductor to satisfy the metering requirements.




     NOTE: Utility owned transformer is grounded, and the system bond jumper is installed in accordance with
     utility standard, the protective bond is sized as per Table 16 based on the ungrounded conductor ampacity per
     10-614(2) and is carried with the main conductors to the service entrance switch. All other equipment
     grounding is for the purpose of establishing an equipotential plane.

10-212(2) – GROUNDING CONNECTIONS FOR SOLIDLY GROUNDED SEPARATELY
           DERIVED SYSTEMS
The bonding conductor in the primary feed to a transformer enclosure will meet the requirements of
the grounding conductor for the transformer.
The system bonding jumper (see 10-004 & 10-614 App B) shall be sized as per Table 16 based on the
secondary current of the transformer which is determined by the primary overcurrent protection device
rating multiplied by the primary to secondary voltage ratio and connected to the enclosure to satisfy the
requirement for the secondary fault return current and the grounding requirement.
See Figure 10-3 and the 3 Phase Dry Core Transformer Tables.

10-302(2)&(3) – USE – IMPEDANCE GROUNDED SYSTEM (see Appendix B)
Impedance grounded systems require the grounding circuit to be electrically continuous and monitored.
This includes the connections from the X0 through the impedance device and the impedance system
bonding jumper to the grounding conductor connection. See Figure 10-6.
The integrity of the impedance grounding system shall be monitored with an audible or visual alarm,
shall be visible to persons monitoring the status of the system and labeled:
‘CONTACT ________________ IF THE SYSTEM IS IN ALARM’. See Table 17.


10-308 – CONDUCTORS USED WITH IMPEDANCE GROUNDING DEVICES
(see Appendix B)
Where the system is not serving neutral loads, the conductor connecting the impedance grounding
device to the neutral point of the system source shall meet the requirements of this Rule and shall not
be installed to the main switchgear, unless otherwise required for metering purposes or installation to
the impedance grounding device. This neutral shall not be distributed and shall be labelled at each
termination point to indicate “NOT FOR NEUTRAL LOADS”.
Impedance grounded systems are not solidly grounded systems. The conductor from the
transformer/source to the impedance device must take the most direct route and is not required to
enter the main service disconnect. This Rule provides several conditions that must be met regarding this
conductor. The minimum conductor size is now #12 AWG copper or #10 AWG aluminum conductors.
The path from the neutral point through the impedance grounding device to the system grounding
electrode shall be electrically continuous and monitored as per 10-302 and Table 17. See Figure 10-6.

10-400 – UNGROUNDED SYSTEMS
Ground fault indication activated by a ground fault shall be visible to persons monitoring the status of
the system and labeled ‘CONTACT _____________ IF LIGHT IS OUT OR SYSTEM IS IN ALARM’.
Regardless of other monitoring systems being implemented, each installation shall have fault indication
lights and/or audible alarm. Installation conditions may dictate that both systems may be required (i.e.,
site conditions, noise levels, etc.).

10-604 – BONDING CONTINUITY FOR SERVICE EQUIPMENT
1) The bonding continuity for service equipment shall be assured by bonding means prescribed in Rule
    10-610.
2) Standard locknuts serving as the bonding means for metal raceway, metal sheath, or cable armour
    connecting to service equipment shall be supplemented by bonding bushings with a bonding
    conductor connecting to a bonding bus within the enclosure
       a) at both ends where the metal raceway, metal sheath, or cable armour serves as the bonding
          means between service equipment; or
       b) at one end where
             i) a bonding conductor is run with circuit conductors; or
             ii) the termination to service equipment is only at one end.
3) Notwithstanding Subrule 2), bonding bushings shall not be required for cable assemblies
   incorporating an internal bonding conductor in continuous contact with the cable armour, provided
   that the internal bonding conductor extends from the cable and connects to the service equipment.

(see Appendix B)
1) The size of a field-installed system bonding jumper shall not be less than that determined by the
   application of Table 16 based on the ampere rating or setting of the overcurrent device protecting
   the ungrounded conductors.
2) The size of the bonding conductor installed in accordance with Rule 10-604 at service equipment
   shall not be less than that determined by the application of Table 16 based on the allowable
   ampacity of the largest ungrounded conductor. See Figure 10-2 & 10-7.
3) The size of a field-installed bonding conductor installed at other than service equipment shall not be
   less than that determined by the application of Table 16 based on:
        a. the overcurrent device protecting the ungrounded conductors; or
        b. the allowable ampacity of the largest ungrounded conductor for installations where the size
            of the circuit conductors is increased to compensate for voltage drop. See Figure 10-7.
4) The size of a field-installed bonding conductor installed with each group of parallel conductors run in
   separate raceways or cables, shall be in accordance with Subrule (3) divided by the number of
   groups of parallel conductors. See Figure 10-7.
5) Notwithstanding Subrules (2), (3) and (4), the bonding conductor shall not be required to be larger
   than the current-carrying conductors.
6) A metal raceway that is permitted to be used as a bonding conductor shall be considered to meet
   the requirements of this rule.
7) A bonding means that is integral to a cable assembly shall be considered to meet the requirements
   of this rule.




            Bonding conductor required in each raceway for parallel conductor installations.




Direct burial parallel conductor installations may require multiple bonds, or a single bond sized to Table

    10-700 – EQUIPOTENTIAL BONDING OF NON-ELECTRICAL EQUIPMENT
    (see Appendix B)
    The metal parts of structures that livestock access shall be bonded as per 10-616(3) and shall include a
    connection to a grounding electrode at each location to provide an equipotential plane. This shall
    include irrigation platforms, irrigation gangways, buildings housing livestock, metal watering bowls, and
    structures supplied with electricity within the areas accessible to livestock.
    Bonding of temporary/portable tents, railings, trusses, and other structures
    Where temporary or portable structures are installed and power cords are in contact with conductive
    apparatus, the apparatus shall be bonded to ground, or the power circuits shall be Class A type GFCI
    protected.
    10-700(c) – Replacement of furnaces
    When a furnace or similar piece of equipment is being replaced, the electrical contractor is responsible
    for bonding the gas line as required by the CEC. The branch circuit cable, providing it has an internal
    bond conductor as per Rule 10-610 and the low voltage thermostat cable, does not require
    replacement. See 26-806(1)(5)(6)(7). Caution: Some new furnaces require 20-amp circuits.
Δ   10-700(c) – Bonding corrugated stainless-steel tubing (CSST)
    New note in Appendix B: When bonding a CSST component of a gas piping system, refer to the
    manufacturer’s instructions.


Δ 10-702 – EQUIPOTENTIAL BONDING INSTALLATION
    3) When non-electrical equipment is being bonded (metal water, waste, and gas lines), bonding can be
    accomplished by permanent conductive connection to non-current carrying conductive parts of
    electrical equipment as long as the electrical equipment is connected to a permanent electrical circuit
    that incorporates a bond conductor, and the equipment (electrical and non-electrical) are associated
    with each other.

    When using Tables D8 – D11 or Tables D17A - D17L to determine conductor ampacity: where the depth
    of conductors specified in Tables D8 – D11 or Tables D17A - D17L is less than the depth requirements of
    Table 53, the depths of Table 53 shall apply. For example, if the minimum cover requirement from Table
    53 when installing a 600 V directly buried single conductor armoured cable is only 450 mm, but the
    selected ampacity of this cable is based on the value of Table D8 in accordance with Diagram D8, then
    the minimum depth of installation of such armoured cable could be reduced to 450 mm, but it could not
    exceed 915 mm, as specified in Diagram D8. If it were to exceed 915 mm, IEEE 835 calculation would be
    required to find the ampacity.
    12-012 (13) – Movement due to settlement or frost
    All underground raceways or cables subject to movement require provisions to be made to prevent
    damage to the conductors or the electrical equipment. The intent of this Rule is to avoid damage to the
    raceway or cable (during settlement/frost). Attention shall be made to rodent access as well as the
    movement of the cable in relation to the terminations during the settling or movement due to frost. This
    may include the use of frost boxes, slip sleeves, cable loop with an expansion joint, or other acceptable
    method.
    12-012(16) – Burial of conductors in proximity to gas lines
    Utility gas lines:
    Electrical wiring shall be installed as per the Utility requirements (e.g., SaskEnergy).
    “The trench for natural gas must be at least 1 metre from the electrical trench.”
    Link to: SaskEnergy – Getting the Site Ready for Service

    Customer owned gas lines:
    Electrical wiring may be installed in the same trench as customer-owned propane or natural gas lines
    provided the conductors are placed at a greater depth and a separation of at least 300 mm of earth or
    150 mm if a treated plank is installed between the piping and conductor.

    Customer owned propane or natural gas lines refers to customer lines supplying customer premises.

    Fine-strand conductors including DLO cables shall terminate in connectors identified for use with fine-
    strand conductors or in standard connectors with the use of ferrules.

    C22.2 No. 65 requires that connectors tested for use with conductors more finely stranded than class C
    indicate the conductor class or classes and the number of strands permitted. This marking may appear
    on the connector, a unit container, or an information sheet packed with the connector unit pack. DLO
    cable is an example of a more finely stranded wire than Class C and therefore the connectors must
    adhere to the marking or labelling requirement for use.

    Ferrules described in 12-116 and 12-406 must be certified to C22.2 No. 291 and C22.2 No. 342.

12-1118 – EXPANSION JOINTS (see Appendix B)
PVC conduit shall be installed as per manufacturer’s specifications and the CEC. For example, assuming a
temperature change of 70 0C, this would mean a minimum of one expansion joint or more may be
required depending on the maximum range of the expansion joint. See Rule 12-1012.

Rules 12-1012, 12-1118, 12-1214 and Appendix B notes
Conduits shall be installed as per manufacturer’s specifications and the CEC. The formula to determine if
excessive expansion requires mitigation is as follows:

ET = LR • TC •CE                 Where:          ET is the total expansion in mm.
                                                 LR is the length of the run in meters
                                                 TC is the temperature change in 0C, and
                                                 CE is the coefficient of linear expansion as per the Table
                                                     B12-4 in Appendix B
NOTE:
     •   The total expansion of the length of the run shall be determined if there are expansion
         concerns.
Example:
For a 20 m run of rigid PVC conduit when the minimum expected temperature is -40°C and the
maximum expected temperature is 30°C, the total expansion is:

              ET= 20 m x (40 + 30) x 0.0520 = 73 mm.
              This exceeds the maximum allowed of 45 mm. Therefore, depending
              on the travel of the expansion joint, one or more would be required.


12-1404 – RESTRICTIONS ON USE – EMT
EMT shall not be used in carwash bay areas due to salt and chemical contaminants. See 22-200(1).


12-1414 – PROVISION FOR BONDING CONTINUITY – EMT

    Explosion seal (ES) — a seal that
Δ
            a) when installed at a cable or conduit entry to an explosion-proof, flameproof “d”, or
              flameproof “db”, enclosure, prevents the ignition of an explosive gas atmosphere outside the
              enclosure;
            b) when installed in a conduit, prevents the passage of an explosion from one portion of the
              conduit system to another; and
            c) minimizes the passage of flammable fluids at atmospheric pressure.

Δ   FLAMMABLE FLUID MIGRATION SEAL (FM) –– a seal that is only intended to prevent the passage of
    flammable fluid at atmospheric pressure. A flammable fluid migration seal is not intended to prevent
    the transmission of an explosion or of flammable fluids under pressure. While explosion seals can meet
    this definition (see the Note to Rule 18-072), other methods using compounds such as silicone or duct
    seal are also suitable, provided that they are installed in a manner that will prevent migration of
    flammable fluids at atmospheric pressure.

    18-004 – CLASSIFICATION OF HAZARDOUS LOCATIONS (see Appendices B, J, and L)
    Hazardous area classification or reclassification as per CEC Appendix L shall be carried out and
    documented by qualified persons and shall be authenticated by the person assuming responsibility
    (Professional Engineer).
    Installations as described within the scope of Sections 18, 19, 20 & 22 shall be the minimum permissible
    classification unless reclassified by a Professional Engineer.
    Area classifications or reclassifications complete with an assessment report and stamped drawings shall
    be provided to the Electrical Inspections department.
    For selection of equipment refer to Table 18.

    Micro-breweries and alcohol distilleries
    Micro-breweries and alcohol distilleries contain several hazardous locations. Plans and hazardous
    location classifications shall be provided to the Electrical Inspections department prior to construction.

    18-006 – AMMONIA COMPRESSOR ROOMS (see Appendices B and L)
    When ammonia is used in a refrigerant system, the room shall be considered a Zone 2 hazardous
    location unless the room is constructed to a Class T machinery room as specified in the CSA standard
    B52-95 Mechanical Refrigeration Code.

    18-008 – LOCATIONS CONTAINING AN EXPLOSIVE DUST ATMOSPHERE
    (see Appendices B and L)
    All grain handling systems are classified Zone 20 locations. The bag handling areas are a Zone 22 location
    when suitably cutoff from the main handling area. See Figures 18-1 to 18-3. The location may be
    reclassified as per Rule 18-004. See Appendix E (of these Interpretations) for dust free room
    requirements.
    Bio diesel and canola crushing plants
    As per Rule 18-008 of the CEC, canola crushing is a Zone 20 location, and all wiring must meet the
    minimum CEC requirements for the installation. Canola storage and product transferring would fall
    under the same area classification.
    In the process of creating bio diesel, an additive must be added. If that product is methanol or another
    volatile additive, a hazard arises. The process must be classified or reclassified as per Rule 18-004.
    Storage of methanol is under the same area classification. Bio diesel storage is the same as regular diesel
    and must also meet all other provincial codes and rules.

Δ   Woodworking facilities
    The CEC classifies these areas as Zone 22 locations. Areas may be reclassified by a Professional Engineer.
    The following wiring methods may be permitted where a housekeeping plan and adequate dust
    collection equipment is installed:
        a. Panelboards, controllers, etc. shall be dust tight or in dust tight enclosures.
        b. Wall surface wiring shall be threaded rigid, EMT (with rain-tight connectors) or TECK cable with
             dust tight TECK connectors.
        c. Ceiling surface wiring may be ordinary location wiring methods.
        d. Boxes shall comply with Rule 18-252(2).
        e. Concealed wiring may be type AC or NM cable.
        f. Concealed boxes and fittings may be ordinary type.
        g. Switch and receptacle covers shall be of the weatherproof type.
        h. Where duplex receptacles are used, a separate self-closing cover will be required for each
             section of the receptacle.
        i. General purpose fluorescent or LED lighting fixtures may be installed:
                           i. directly on the ceiling; or
                          ii. suspended and provided with dust shields to prevent the accumulation of dust.
    The area is deemed to have a housekeeping plan and adequate dust collection when all surfaces have no
    more than 1.75 mm of dust accumulation (about the thickness of a nickel).
    Note: For the purposes of this rule, non-commercial, residential garages and shops may not be
    considered woodworking facilities and may be considered an ordinary location.

    Health care facility definitions (Class A, B, and C) can be located in CEC Handbook. Additional
    resources can be found in CSA Z32.
    24-002 – Special terminology
    Basic care area — a patient care area where body contact between a patient and medical electrical
    equipment is neither frequent nor usual.
    Intermediate care area — a patient care area in which body contact between a patient and medical
    electrical equipment is frequent or normal.
    Critical care area — a patient care area that is an anaesthetizing location, or in which cardiac contact
    between a patient and medical electrical equipment is frequent or normal.


    24-002 – DEFINING PATIENT CARE AREAS/ENVIRONMENTS
    Contractors need to be aware of the determination of patient care areas and provide this information to
    the Electrical Inspector prior to commencing work. Plans shall be submitted with indication of different
    patient care levels (basic, intermediate, or critical), patient care environments and branch circuit wiring
    details.
    A rough-in inspection shall be booked prior to closing in of walls. See 2-012.
    Patient care areas are defined by the CAN/CSA-Z32 standard and include, but are not limited to, walk-in
    medical clinics, dental clinics, chiropractic clinics, massage/physiotherapy, optometrists, and others. This
    means that the specific rooms of a clinic in which treatment is given may be required to be wired in
    accordance with Section 24 methods.
    The health region, clinic or hospital administrators are the personnel who will determine the area use
    for their facilities.

A sample selection for a 20 KW furnace follows: The ampacity of the conductors supplying the furnace
and the size of the overcurrent devices are determined by applying Rule 62-114.
The overcurrent device for the service must be sized so that the total connected load of the heating
equipment does not exceed 80% of the rating of the overcurrent device in accordance with subrule (6).
In this case, the load is 83.3 amps; the minimum size of overcurrent device is 83.3/0.8 = 104 Amperes.
Rule 62-114(8) the next available fuse is 125 A.
Since this fuse is supplying a heating load, Rule 14-610 requires that the fuses be a time delay type or HRC
Form I.
The conductor size is determined by applying Rule 62-114(7). The conductor must have the ampacity
sufficient to carry the load and must have an ampacity rating at least 80% of the rating or setting of the
branch circuit overcurrent device. A conductor rated at 100 amperes, e.g., #3 AWG R90 (75°C column of
Table 2) would satisfy these requirements.

64-202 – VOLTAGE OF SOLAR PHOTOVOLTAIC SYSTEMS
1)    The maximum photovoltaic source and output circuit voltage shall be the rated open circuit voltage
      (Voc) of the photovoltaic power source X 125%; or
2)    The source and circuit output voltage (VMPC) may be calculated using the open circuit voltage (Voc)
      of the photovoltaic power source, the difference between 25 ⁰C and the lowest expected daily
      minimum temperature (Tm) (available from Environment Canada “Canadian Climate Norms”) and
      the voltage temperature coefficient (Tk) as specified by the manufacturer.

                                   VMPC ______ = Voc x [1+(Tm – 25) x Tk]




3)    The photovoltaic source and output circuits for installations in or on a dwelling unit shall be
      permitted to have a voltage not exceeding 600V DC.
4)    The voltages of solar photovoltaic systems may exceed 750V DC but not more than 1500 V DC and
      shall not be required to meet the requirements of 36-204, 36-208 & 36-214 provided they are
      maintained by qualified persons, are inaccessible to the public, and labelled “DANGER ______V
      DC”. See Appendix M.


64-210 – WIRING METHOD
(2) & (3) Where the source and output circuits operate at a maximum system voltage greater than 30V,
          the wiring is deemed inaccessible to the public and not readily accessible if it is:
          • contained in a raceway;
          • contained behind metal screening or guarding with holes not exceeding 13mm x 13mm;
          • elevated 3 m or more above grade level; or
          • located within a fenced enclosure in accordance with Rule 26-304, 26-312, and 26-314
(4) Conductors and cables shall be mechanically protected and supported as per this rule throughout

103                                                         Inspiring and Shaping Excellence in Public Safety
(5) Rodent protection is required on all insulated conductors or cables, with the exception of armoured
    cables or MI cables, installed on or above a building by enclosing them in material such as approved
    raceways, expanded metal, solid metal, metal screening (maximum 13 mm x 13 mm holes) or other
    acceptable protection.
(7) RPV conductors shall be permitted for the module interconnections if they are contained in a
    raceway;
(9) Types RPV and RPVU conductors installed inside a building or structure shall be contained in a

NOTES:
      •   For rodent protection, module level arc fault protection must be part of the module and listed in
          the module manufacturers’ installation instructions.
      •   Modules cannot be drilled into for mounting of rodent protection.


64-212 – INSULATED CONDUCTOR MARKING OR COLOUR CODING
RPVU or RPV conductors shall be coloured red for positive, black for negative or permanent surface
printing of the polarity on the insulated conductors. TECK 90 cables may be field marked in a permanent
manner (heat shrink).


64-214 – OVERCURRENT PROTECTION FOR APPARATUS AND CONDUCTORS
Maximum photovoltaic source circuit short-circuit-current (Isc) is equal to the sum of the short circuit
current for all the source circuits connected in parallel minus the short circuit current for one of the
photovoltaic source circuits.
If the photovoltaic source circuit short-circuit-current (Isc) (sum of all parallel strings minus one string)
exceeds the maximum series fuse rating (reverse current rating) (typically 15A or 20A) or the ampacity
of the source circuit conductor, then OC protection will be required on each ungrounded conductor.
E.g., String ISC = 9.5A x 3(strings) = 28.5 – 9.5 = 19A x 125% = 23.75A; DC fusing is required for 15A or 20A
series fuse rating.
Where the value specified in Subrule 2) does not correspond to the standard rating of an overcurrent
device, the next higher standard rating shall be permitted. For a two-wire ungrounded system, the
overcurrent protection may be located in one source or output conductor only but must be in the same
polarity for the entire system.
DC overcurrent devices shall be accessible and grouped where practicable.
NOTE:
      •   AC overcurrent protective devices must be readily accessible. See Rule 14-106.

APPENDIX E – DUST FREE ROOMS
See rules for Appendix J for Class II and Class III Hazardous Locations and Rule 18-008, Zones 20, 21, 22
Hazardous areas for Grain Handling. Grain Elevators, Seed Cleaning Plants and Feed Mills.

NOTE: This Appendix is an informative (non-mandatory) part of this Standard.

E1 – INTRODUCTION
This Appendix covers recommended practices for the housing of electrical equipment. With respect to
actual constructional requirements, it is not practical to cover all materials and methods that are or may
become available and, therefore, any specific details mentioned in this Appendix are to be considered
examples rather than specific requirements. The National Building Code of Canada or any other building
code that may be in force in any particular locality should take precedence over this Appendix and
should be consulted in this respect.

E2 – SCOPE
This Appendix applies to the construction of dust-free rooms built adjacent to or as part of buildings
that, by the nature of their use or occupancy, are subject to accumulations of dusts that may create a
fire or explosion hazard or that may be detrimental to the proper operation of electrical equipment not
provided with dust-tight enclosures.

E3 – DEFINITION
The following definition applies in this Appendix:
Dust-free room — a room, building, or other area, of a size that permits the entrance of persons for
operation and maintenance purposes and constructed so that the quantity of dust that can enter will
not create a hazardous condition.

E4 – USE
E4.1
Dust-free rooms are intended to be used to house electrical equipment except equipment required by
the latest edition of the CEC to be installed in vaults.
E4.2
Dust-free rooms should not be used for any manufacturing, processing, maintenance, storage, or other
purposes except those that may be essential for the proper operation and maintenance of the electrical
equipment that they house.

E5 – ENCLOSING OF ELECTRICAL EQUIPMENT
E5.1
Electrical equipment in dust-free rooms need not be of types approved for Class II locations.

E5.2
Where access to the dust-free room by unauthorized persons is permitted, the electrical equipment
should be enclosed, guarded, protected, etc. as required by the latest edition of the CEC for ordinary
locations.
E5.3


122                                                         Inspiring and Shaping Excellence in Public Safety
Where access is to unauthorized persons only, enclosures may be omitted as provided for by the latest
edition of the CEC. (E.g., Section 26).

E6 – MATERIALS AND METHODS OF CONSTRUCTION
Materials used for the construction of dust-free rooms and the method of construction should fulfill the
following conditions:
f) the enclosure of the room should be as impervious to the passage of dust from outside the room as
     is practicable;
g) the various components, walls, floors, ceilings, etc. should be capable of safely supporting the live
     and dead loads (including impact) to which they are liable to be subjected;
h) there should be no likelihood that dust passages will be created due to shrinkage, breaking, or
     cracking;
i) the completed structure should have a fire resistance rating of 1 h or better;
j) in buildings constructed of non-combustible materials, the rooms should also be constructed of non-
     combustible material, but in other buildings, the rooms may be constructed of combustible
     materials with non-combustible facing on at least the inner surfaces; and
k) if it is necessary that shafts or other rotating or sliding members be used to connect equipment
     outside the room with that inside, suitable means such as seals, gaskets, baffles, etc. should be
     provided to prevent passage of dust through the necessary openings.

E7 – FLOORS
Some acceptable floor constructions are as follows:
a) solid concrete slab of minimum thickness 75 mm and reinforced as necessary; or
b) steel joists with welded plate metal floor or concrete slabs of minimum thickness 50 mm over the
   joists and 22 mm Portland cement plaster on metal lath under them.
Wherever necessary, floors should be surfaced with insulating material to prevent shock hazard.

E8 – WALLS
Some acceptable wall constructions are as follows, and it is to be noted that lath and plaster on both
sides must have other construction built into the wall to ensure continuance of the dust-free features,
and plywood joints must be backed by studding:
a) monolithic concrete of minimum thickness 100 mm reinforced as necessary;
b) built-up masonry consisting of
    i) solid bricks of minimum thickness 95 mm;
    ii) hollow tile of minimum thickness 75 mm if plastered both sides, and 150 mm if not plastered; or
    iii) hollow concrete or cinder concrete block of minimum thickness 125 mm if plastered both sides,
         and 200 mm if not plastered; or
c) stud construction of 50 mm if of metal or 100 mm if of wood, faced on the outside with metal or
    perforated gypsum lath with 19 mm gypsum or 22 mm Portland cement plaster, faced on the inside
    with
    i) metal-faced laminated wood;
    ii) laminated wood with 19 mm gypsum or 22 mm Portland cement plaster on metal or perforated
         gypsum lath;
    iii) laminated wood with fire-resisting non-metallic facing; or

123                                                       Inspiring and Shaping Excellence in Public Safety
      iv) sheet metal equivalent to 1.69 mm (No. 14 MSG) steel with welded or riveted locked-seam
          joints secured to metal studs by welding or by self-locking screws.

E9 – CEILINGS
Ceilings, if load bearing, should have the same construction as floors, but if non-load bearing, may be
constructed similarly to walls with wood joists, if used, of greater depth in accordance with the span.

E10 – CUBICLE CONSTRUCTION
E10.1
Where the room is constructed as a free-standing cubicle with walls and ceiling not forming a part of
and spaced away from the structure of the building proper, the walls and ceiling may be of sheet steel
not less than 1.69 mm (No. 14 MSG) thick, suitably joined and reinforced as may be necessary.
E10.2
If the floor is elevated above the floor of the building proper, it may be constructed in accordance with
Clause E7 and the plaster may be omitted.

E11 – DOORS
E11.1
Doors giving access to the room from dusty locations should be
l) either metal-clad or hollow metal and weather-stripped or otherwise arranged to prevent dust
     leakage at the edges of frames and sills; and
m) equipped with self-closers.
E11.2
If operation of the electrical equipment requires entry to the room from dusty locations, two hinged
doors with a 1.5 m vestibule between them should be provided, but where entry is necessary for
maintenance only, single doors may be used.
E11.3
Doors giving access to the room from a dust-free atmosphere may be of ordinary types.
E11.4
If more than one point of access to a room is provided, all but the principal one should be either
securely locked or other adequate means should be used to prevent unauthorized traffic through the
room.
E11.5
All doors should be provided with means whereby they can be readily unlocked and opened from the
inside without the use of a removable key.

E12 – WINDOWS
E12.1
Windows facing dusty locations should have a fixed metal sash and wired glass.
E12.2
Windows in exterior walls may be arranged for opening if it is reasonably certain that the surrounding
exterior area will remain sufficiently dust-free.

E13 – VENTILATION
E13.1


124                                                         Inspiring and Shaping Excellence in Public Safety
Ventilation by clean air should be adequate for the dissipation of heat from the electrical apparatus
installed.
E13.2
If ventilation is by means of forced air circulation, the air should be forced into the room rather than
exhausted out of it.
E13.3
It is recommended that the air in the room be kept at a pressure slightly above atmospheric, which will
tend to blow any dust out of the room rather than have it sucked in.
E13.4
The amount of ventilating air required is difficult to specify in an empirical value because it depends on
n) the size of the room;
o) the dissipating ability of walls and ceilings;
p) the amount and nature of the electrical equipment; and
q) the temperature of the incoming air.
E13.5
The cooling effect may be obtained by radiation alone (it the area is sufficient), by ventilation alone, or
by a combination of both.
