Email June 28, Now in its 24th edition, the Canadian Electrical Code, Part I includes a number of significant updates and changes to better help electrical workers in the safe maintenance of electrical equipment and create safer electrical installations. This edition features important revisions to many sections. For example, Section 26 now mandates the use of tamper-resistant receptacles in additional areas where children may be present.
Section 62 now requires ground fault circuit interrupter protection for heating devices and controls in proximity to tubs, sinks, and shower stalls. Section 10 has been updated, reorganized, and significantly reduced in length. Requirements for power over ethernet systems have been added to Section 16, and requirements for marinas, wharves, and similar facilities have been substantially updated and reorganized in Section Read more below about the top 15 changes to the code.
Through these cables, power levels approaching W are possible, along with simultaneously communications between devices and systems.
POE is typically implemented as a "structured" cable system, wherein cables are bundled together for extended lengths. Cable heating is a function of the power it carries and as such, installation and layout become critical factors in ensuring safe operation.
Installation of identified conductor at control locations Code — Two wire simple switch loop acceptable Code — Identified conductor required at every control location Control devices are increasingly used as an essential part of energy management systems.
Many of these devices require power to operate, and where used in a simple switch loop, create a small current through the bonding conductor. As the number of devices increases, the cumulative current through the bonding system will become unacceptable. New Subrule 2 now mandates that an identified conductor be installed at each manual or automatic control location. This requirement applies to all occupancy types. Bonding and grounding Code — 15 pages long and two tables Code — 8 pages long and one table Section 10 requirements have been reorganized into a more logical flow of requirements and significantly reduced in size.
Objectives for solidly grounded, impedance grounded, and ungrounded systems are clearly specified at the beginning of the Section. Tables 16A and 16B have been combined into a single Table, with Rule providing specific conditions for selecting the size of bonding conductor or bonding jumper. Arc fault circuit interrupters Code — AFCI protection required, with some exemptions Code — exemptions tightened, application to existing circuits clarified Clarification is now provided for AFCI protection of existing branch circuits that are extended due to renovations or additions.
Exemptions from AFCI protection have been reduced or removed for number of areas including branch circuits supplying smoke alarms, carbon monoxide alarms, and bathrooms.
Disconnecting means for LED luminaires Code — disconnecting means required for fluorescent ballasts Code — disconnecting means required for fluorescent ballasts and LED drivers To support safe maintenance, the Code has for several editions required disconnecting means for fluorescent luminaires utilizing double ended lamps and operating at more than V.
With increased use of LED lighting, the requirements have been extended to LED luminaires exceeding V to ground with double ended lamps. Tamper resistant TR receptacles Code — TR receptacles required in dwelling units and child care facilities Code — TR receptacles required in additional occupancy types The requirement for tamper resistant receptacles in dwelling units and child care facilities is expanded to include other areas where children may be present including hotel guest rooms, preschools, and elementary education facilities.
Equipment connected to devices having Class 2 outputs Code — approval requirement based on application Code — approval based on voltage and application. Voltage limited by location. Products having a Class 2 output are covered by a number of standards including C The output voltage from these supplies can vary substantially in magnitude and waveform, up to 60 Vdc. Revisions to Section 16 now set the requirements for approval of such equipment based on application, location, voltage, and waveform, and maximum permitted voltages for dry, damp, and wet locations.
Continuous loads Code — complex continuous load requirements Code — continuous load requirements simplified. Rule has been one of the more misunderstood Rules in the Code, with varying interpretations of how it should be applied. In both cases, the Subrules now simply require two things: 1 that the continuous load not exceed the continuous operation marking on the fused switch or circuit breaker, and 2 that the continuous load not exceed a specified percentage of the allowable ampacity determined from Section 4.
Gone are references to specific columns in Tables, underground installations, and derating correction factors. In addition, conductor ampacities are determined by Section 4, not 8, as confirmed by several related changes to Section 8.
Finally, the Subrule has been inconsistently applied. As such, Subrule 1 was deleted. Marking for maximum continuous load Code — no labelling requirement Code — maximum continuous load required to be field marked on equipment The maximum continuous load determined for a given installation may be substantially less than the equipment rating.
However, there is no requirement to communicate this information to maintenance personnel, installers, or inspectors, for purposes of future maintenance or modification of the electrical system.
As a result, new Subrule 4 requires that a caution label be applied to the equipment to indicate the maximum permitted continuous load. Electric shock drowning Code — 15 and 20 A receptacles require GFCI protection Code — ground fault protection for feeders, GFCI protection for receptacles Much research has been conducted on the phenomenon known as electric shock drowning.
Section 78 has been extensively updated to require GFCI and Ground Fault protection for branch circuits and feeders respectively. The scope of Section 78 has been expanded to include additional types of structures such as floating piers and docking facilities, and the Rules have been re-arranged to simplify navigation of the Section. Electric vehicle supply equipment EVSE can draw a substantial load when in the charging mode.
For existing buildings, the addition of EVSE can result in the total load exceeding the existing service capacity. In this case, the first option is to increase the service size. A second option is to install a system to monitor the power being drawn by EVSEs and other building loads, and control the EVSE loads such that the overall load does not exceed the limits of the existing service, feeders, and branch circuits.
Kitchen wall not counter receptacles Code — separate branch circuit required Code — separate branch circuit not required Wall receptacles provided in a kitchen are required to be supplied by a separate circuit. However, this requirement predates the requirement for counter receptacles and circuits. Given that many kitchens are now used as general living areas, and that receptacles are now required to be provided along the kitchen wall in the same fashion as a living room, there is no longer a need for a dedicated circuit.
Consequently, the requirement has been deleted. Refrigerators Code — separate circuit required for each receptacle installed for a refrigerator Code — separate circuit only required for mandated refrigerator receptacle The existing wording of required a separate circuit for each receptacle installed for a refrigerator.
This requirement is now relaxed by permitting a dedicated circuit to supply more than one refrigerator receptacle. It has also been revised to more clearly state that the requirement only applies to receptacles mandated by d i for refrigerators in kitchens.
The requirement does not apply to refrigerators installed in other locations. Pre-order your copy of the CE Code here.
Multi Provinces Electrical Code Book
It clearly explains the legal requirements for inspection in each province so that homeowners can safely, easily and confidently make their own electrical installations. Anyone installing electrical wiring in a residence is required to comply with electrical Code rules to ensure safe and legal installation. If the installation will be inspected, technically, all electrical installations, of any size, are required to be inspected it must pass inspection, or the installer may need to rewire some of their job and pay for a re-inspection. This additional expense is often more than three times the cost of this book. Electrical Code Simplified is the only book that can help you meet this tough standard. Clear, Straightforward Instruction This book speaks clearly to the point. The legalese used in the Code is replaced with easily understandable explanations.
