Canadian Standards AssociationCanadian Electrical Code, Part IΔPrefaceThis 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 , , , , , , , , , 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 The term “light fixture” has been replaced by “luminaire” throughout the Code, and all references to HFT conduit have been deleted.General arrangement The Code is divided into numbered Sections, each covering some main division of the work. Sections 0 to 16 and 26 are considered general sections, and the other sections supplement or amend the general sections. The Sections are divided into numbered Rules, with captions for easy reference, as follows: (a) Numbering system ― With the exception of Section 38, even numbers have been used throughout to identify Sections and Rules. Rule numbers consist of the Section number separated by a hyphen from the 3- or 4-digit figure. The intention in general is that odd numbers may be used for new Rules required by interim revisions. Due to the introduction of some new Rules and the deletion of some existing Rules during the revision of each edition, the Rule numbers for any particular requirement are not always the same in successive editions. (b) Subdivision of Rules ― Rules are subdivided in the manner illustrated by Rules 8-204 and 8-206, and the subdivisions are identified as follows:00-000 (1) (a) (i) (A) Rule Subrule Item Item Item(c)Reference to other Rules, etc. ― Where reference is made to two or more Rules (e.g., Rules 10-200 to 10-206), the first and last Rules mentioned are included in the reference. Where reference is made to a Subrule or Item in the same Rule, only the Subrule number and/or Item letter and the word “Subrule” or “Item” need be mentioned. If the reference is to another Rule or Section, then the Rule number and the word “Rule” shall be stated (e.g., “Rule 10-200(3)” and not “Subrule (3) of Rule 10-200”).The principal changes that have been made between the 2006 edition of the Canadian Electrical Code, Part I, and this new edition published in 2009 are marked in the text of the Code by the symbol delta (Δ) in the margin. Where revisions to or deletions from the text have caused existing Rules to be renumbered, only the first renumbered Rule in the sequence is marked. Users of the Code are advised that the change markers in the text are not intended to be all-inclusive and are provided a such markers cannot constitute a comprehensive guide to the reorganization or revision of the Code. Care must therefore be taken not to rely on the change markers to determine the current requirements of the Code. As always, users of the Code must consider the entire Code and any local amendments.Acknowledgement The use of material contained in the National Electrical Code is acknowledged. The history and operation of the Canadian Electrical Code, Part I The preliminary work in preparing the Canadian Electrical Code began in 1920 when a special committee, appointed by the main Committee of the Canadian Engineering Standards Association, recommended its? Canadian Standards AssociationxxvCanadian Electrical Code, Part Idevelopment. A third meeting of this Committee was held in June 1927 with representatives from Nova Scotia, Québec, Ontario, Manitoba, Saskatchewan, and British Columbia in attendance. At this meeting, the revised draft, which had been discussed at the previous two meetings, was formally approved and it was resolved that it be printed as Part I of the Canadian Electrical Code. The present Committee on the CE Code, Part I, is composed of 41 members, with representation from inspection authorities, industry, utilities, and allied interests. The main Committee meets once a year and deals with reports that have been submitted by the Section Subcommittees, which work under the jurisdiction of the main Committee. Suggestions for changes to the Code may be made by any member of the Committee or anyone outside the Committee as outlined in Clause C6. January 2009Notes: (1) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. (2) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (3) All enquiries regarding this Standard should be addressed to Canadian Standards Association, 5060 Spectrum Way, Suite 100, Mississauga, Ontario, Canada L4W 5N6. Requests for interpretation will also be accepted by the Committee (see Clause C9). They should be worded in such a manner as to permit a specific “yes” or “no” answer based on the literal text of the requirement concerned. Interpretations are published in CSA’s periodical Info Update, which is available on the CSA Web site at www.csa.ca.xxvi?
