Full Description

Preface 

This twenty-sixth edition of the Canadian Electrical Code, Part I, was approved by the Committee on the Canadian Electrical Code, Part I, and by the Regulatory Authority Committee at their June 2023 meetings. This twenty-sixth edition supersedes the previous editions published in 2021, 2018, 2015, 2012, 2009, 2006, 2002, 1998, 1994, 1990, 1986, 1982, 1978, 1975, 1972, 1969, 1966, 1962, 1958, 1953, 1947, 1939, 1935, 1930, and 1927. This edition contains important revisions to many Sections. Section 64 contains major revisions for energy storage and renewable energy systems, including a new Subsection for residential occupancies and updates to photovoltaic system requirements. Several important changes appear in Section 68, including new disconnecting means and bonding requirements for conductive pool infrastructure. Section 66 now requires ground fault circuit interrupter protection for receptacles placed in temporary installations such as tents for outdoor functions. Other significant revisions in this edition include the following: • voltage definitions for dc circuit voltages have been revised in Section 0; • Section 2 sees the addition of new requirements for reduction of arcing fault clearing times and revisions to clarify use of ingress protection designations; • in addition to traditional AWG and kcmil sizes, use of conductors sized in mm2 are now recognized through revisions to Section 4 and a new Table; • load calculations for installations with electric vehicle supply equipment have been revised in Section 8 and simplified through the deletion of Table 38; • many new products and updates to wiring methods are recognized in Section 12, including sag and span requirements for overhead installations and new Rules for non-metallic jacketed cable; • sealing requirements have been substantially revised in Section 18 and Annex J18; • Section 36 now features rules for installation of high-voltage couplers (i.e., devices that provide a means to repeatedly join and separate portable power cables); • Table 11 has been formatted into two new Tables (11A and 11B) and made easier to use through a layout similar to Table 19; • an index and Annexes A.1 and A.2 of Appendix A have been reinstated; • Appendix K has been deleted; and • the word "allowable" has been removed from "allowable ampacities" throughout most of the Code. Many of the changes in this edition were developed by cross-functional working groups. Their work is gratefully acknowledged. This Code has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
