C22.1-15 - Canadian electrical code, part I (23rd edition), safety standard for electrical installations and C22.1HB-15 - CE code handbook, an explanation of rules of the Canadian electrical code, part 1


This twenty-third 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 2014 meetings in Victoria, British Columbia. This twenty-third edition supersedes the previous editions, published in 2012, 2009, 2006, 2002, 1998, 1994, 1990, 1986, 1982, 1978, 1975, 1972, 1969, 1966, 1962, 1958, 1953, 1947, 1939, 1935, 1930, and 1927.

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:
  1. 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.

  2. 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     |   Rule

    (1)            |   Subrule

       (a)         |   Item

           (i)      |   item

             (A)   |   item

  3. 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 2012 edition of the Canadian Electrical Code, Part I, and this new edition published in 2015 are marked in the text of the Code by the symbol delta (Δ) in the margin. Users of the Code are advised that the change markers in the text are not intended to be all-inclusive and are provided as a convenience only; 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.


This Code covers all electrical work and electrical equipment operating or intended to operate at all voltages in electrical installations for buildings, structures, and premises, including factory-built relocatable and non-relocatable structures, and self-propelled marine vessels stationary for periods exceeding five months and connected to a shore supply of electricity continuously or from time to time, with the following exceptions:
  1. installations or equipment employed by an electric, communication, or community antenna distribution system utility in the exercise of its function as a utility, as recognized by the regulatory authority having jurisdiction, and located outdoors or in buildings or sections of buildings used for that purpose;

  2. equipment and facilities that are used in the operation of an electric railway and are supplied exclusively from circuits that supply the motive power;

  3. installations or equipment used for railway signalling and railway communication purposes, and located outdoors or in buildings or sections of buildings used exclusively for such installations;

  4. aircraft; and

  5. electrical systems in ships that are regulated under Transport Canada.

This Code and any standards referenced in it do not make or imply any assurance or guarantee by the authority adopting this Code with respect to life expectancy, durability, or operating performance of equipment and materials so referenced.

Introduction to the CE Code Handbook

The 2015 Canadian Electrical Code Handbook provides background information on the rationale behind the requirements in the Canadian Electrical Code, Part I, and gives an explanation of the rules in plain, easy-to-understand language. The 2015 CE Code Handbook has been updated to incorporate the changes to the 2015 CE Code, and continues to be a key component of the Canadian electrical safety system.

The Handbook provides a clear understanding of the safety and installation requirements of the CE Code related to industrial, commercial and residential installations. Following the navigational structure of the Code, the CE Handbook helps you quickly find pertinent information and outlines detailed scenarios to help avoid misinterpretations. The CE Code Handbook contains examples, calculations and graphics to help you implement the Code.

Developed by technical experts selected for their detailed knowledge and understanding of the CE Code and extensive experience in putting Code principles into practice. It is important to note that the CE Code Handbook does not define each clause and section of the CE Code; only sections and clauses that require further clarification are referenced in the Handbook.
