CE Code 2015 - Highlights Taken from the CE Code 2015 Preface: http://shop.csa.ca/en/canada/c221-canadian-electrical-code/c221-15-package/invt/27013892015pkg;

General - The term “injury” has been replaced with “damage” throughout the Code;

Section 4 now contains requirements for high-voltage cable ampacities and clarified Rules for conductor termination temperature. In addition, a new table (Table 39) simplifies residential service and feeder conductor selection (currently Table 5E!);

Section 8 - More options are provided for load and voltage drop calculations;

Section 10 - Bonding conductor selection has been clarified through the addition of the new Tables 16A and 16B;

Section 12 contains many new and revised requirements for wiring methods, and the conduit fill tables have been expanded;

Section 18 has undergone major revisions. Requirements for Class II and Class III locations have been relocated to Appendix J, and requirements for explosive dust atmospheres based on IEC Zone 20, Zone 21, and Zone 22 have been added;

Section 26 - Requirements for arc-fault protection have been expanded and clarified;

Section 50 has been merged with Section 64; and

Section 62 has been completely rewritten.

Now we will consider the above in a little bit more detail.

18-004 Classification of hazardous locations (see Appendices B, J, and L)

Hazardous locations shall be classified according to the nature of the hazard, as follows:

(a) explosive gas atmospheres; or

(b) explosive dust atmospheres.

18-006 Locations containing an explosive gas atmosphere (see Appendix B)

Explosive gas atmospheres shall be divided into Zones 0, 1, and 2 based upon frequency of occurrence and

duration of an explosive gas atmosphere.

(b) the location is adjacent to a Zone 1 location, from which explosive gas atmospheres could be communicated, unless such communication is prevented by adequate positive-pressure ventilation from a source of clean air, and effective safeguards against ventilation failure are provided.

Zone 20 — a location in which an explosive dust atmosphere, in the form of a cloud of dust in air, is present continuously, or for long periods, or frequently.

Zone 21 — a location in which an explosive dust atmosphere, in the form of a cloud of dust in air, is likely to occur in normal operation occasionally.

Zone 22 — location in which an explosive dust atmosphere, in the form of a cloud of dust in air, is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

Branch circuits for residential occupancies

26-720 Special terminology

In this Subsection, the following definitions apply:

Arc-fault protection — a means of recognizing characteristics unique to both series and parallel arc-faults and de-energizing the circuit when an arc-fault is detected.

Combination-type arc-fault circuit interrupter — a device that provides both series and parallel arc-fault protection to the entire branch circuit wiring, including cord sets and power supply cords connected to the outlets, against the unwanted effects of arcing.

Outlet branch-circuit-type arc-fault circuit interrupter — a device that provides both series and parallel arc-fault protection to downstream branch circuit wiring, cord sets, and power supply cords against the unwanted effects of arcing and also provides series arc-fault protection to upstream branch circuit wiring. 21

Safety Services



Branch circuits for residential occupancies

(f) each branch circuit supplying 125 V receptacles rated 20 A or less shall be protected by a combination-type arc-fault circuit interrupter, except for branch circuits supplying
