a) 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;
b) equipment and facilities that are used in the operation of an electric railway and are supplied exclusively from circuits that supply the motive power;
c) 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;

Introduction to the Canadian Electrical Code Handbook
This Handbook provides background information on the reasons behind the requirements in the Canadian Electrical Code, Part I, and gives an explanation of the Rules in plain, easy-to-understand language. The Handbook is intended to provide a clearer understanding of the safety requirements of the Code.
The content of this Handbook is not meant to form a code of mandatory requirements. The mandatory language (shall) that is used in the CE Code, Part I, has not been used here. Care has been taken to ensure that the intent of the Code Rules is clear to the users of the Handbook. However, users of the Handbook must not under any circumstances rely on it to determine the current requirements of the Code. As always, reference must be made to the Code itself and any local amendments. Consult with the authority having jurisdiction (AHJ) for specific Code interpretations. CSA Group does not assume responsibility for any errors or omissions resulting from the information contained in this Handbook.
The Rules in the CE Code, Part I, are divided into two groups. Sections 0 to 16 and 26 are considered general Sections, and the other Sections supplement or amend those general Sections. Therefore, a requirement in the supplementary Sections takes precedence over a general requirement. For example:
• Rule 12-1008 requires 3 threads to be engaged when making a threaded connection, whereas Rule 18-102 requires 5 threads to be engaged when making a threaded connection in a Zone 1 area.
• Section 4 permits the use of aluminum conductors, but Rule 32-100 does not allow aluminum conductors to be used in fire alarm systems.
