CSA C22.10-10 Historical

By the Regulation amending the Construction Code (Order in Council 1062-2010 of December 1st, 2010), the Government subsequently approved the Canadian Electrical Code, Part I (Twenty-first Edition), with the applicable Québec amendments. That Code replaces the Twentieth Edition and comes into force on March 1st, 2011.

A free pocketbook related to the CE Code and to the Québec Construction Code, Chapter V - Electricity is included with the paper version of the Code.

The Québec amendments are published on blue pages and are incorporated at the beginning of the Canadian Electrical Code. A fleur de lys followed by the word "Amended" in the left margin of the Canadian Electrical Code indicates to Québec users that these Rules have been amended for Québec.

Preface

This twenty-first 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 2008 meetings in Calgary, Alberta.

This twenty-first edition supersedes the previous editions, published in 2006, 2002, 1998, 1994, 1990, 1986, 1982, 1978, 1975, 1972, 1969, 1966, 1962, 1958, 1953, 1947, 1939, 1935, 1930, and 1927.

A new Section 58 was added to cover requirements for passenger ropeways and similar equipment. In addition, there are significant changes to Sections 0, 10, 18, 26, 46, and 68. Sections 12 and 32 have been revised to reflect new technology and industry practices.

The designation for receptacle configuration type 5-20RA ("T-slot") has been revised to 5-20R throughout the Code, and the configuration previously designated as 5-20R is now designated 5-20RA to recognize that this configuration is being phased out. Similarly, the designations for 6-20R and 6-20RA configurations have been interchanged throughout the Code.
The term "light fixture" has been replaced by "luminaire" throughout the Code, and all references to HFT conduit have been deleted. See more
