Preface
This nineteenth edition of the Canadian Electrical Code, Part I, was approved by the Committee on Canadian Electrical Code, Part I, and by the Regulatory Authority Committee at their June 2001 meetings in St. John’s, Newfoundland. This nineteenth edition supersedes the previous editions, published in 1927, 1930, 1935, 1939, 1947, 1953, 1958, 1962, 1966, 1969, 1972, 1975, 1978, 1982, 1986, 1990, 1994, and 1998.
Sections 0 to 16 and 26 are considered general sections, the others being supplementary or amendatory sections.
Sections 34, 38, 50, and 66 have been revised considerably to reflect new technology and industry practices, and to harmonize with the National Electrical Code and product standards.
Requirements have been added for the installation of arc-fault circuit interrupters as well as surge protectors.
Various requirements were revised, particularly for heat tracing cables and luminaires, as a result of continuing efforts toward harmonization.
In addition, there are significant changes to Sections 0, 12, 18, 20, 24, 26, 30, 54, 62, 70, and 72.
