Preface

This twenty-third edition of the Canadian Electrical Code, Part I, was approved by the Canadian Electricity Code Committee, Part I, and by the Committee on Regulatory Credentials during their meetings held in June 2014 in Charlottetown, Prince Edward Island. It replaces 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. . 

In this edition, many sections have undergone major revisions. For example, Section 4 now states requirements for the ampacity of high-voltage cables and the temperature-related items at the end of the conductors have been clarified. In addition, the new Table 39 simplifies the choice of service and branch conductors for residential use. More options are given for the calculation of the load and the voltage drop. 

Clarifications have been made to the choice of the conductor of continuity of masses thanks to the addition of tables 16A and 16B. In addition, in section 12, requirements for wiring methods were added and revised, and tables for the number of drivers in a conduit were added. 

Section 18 has undergone significant changes. The requirements for Class II and Class III locations are now in Appendix J, and requirements for explosive dust atmospheres based on IEC zones 20, 21 and 22 have been added to the section. 18. The requirements are now broken down as follows: 

Zones 0, 1, 2, 20, 21 and 22 - Section 18

Class I, II and III and corresponding divisions - Appendix J 

Note: A reference to Class I only constitutes a general reference all classes of gaseous explosive atmospheres of zone 0, zone 1 and zone 2. 

A reference to Class II or Class III only constitutes a general reference to all classes of explosive atmospheres due to zone 20, zone 21 and zone 22 dust. 

A specific reference to an area of ​​a class location I is a reference to this area. 

There is currently no reference to class II or class III areas or divisions in the sections of this Code (ie, sections 0 to 86). 

Other changes have been made to this edition, including: 

• requirements for arc protection have been expanded and clarified
• section 50 has been incorporated in section 64
• section 62 has been completely rewritten

in the English version, the term injury was replaced by the term damage throughout the Code. It should be noted that this change in terminology does not affect the French text.

Many of the changes made in this edition are the result of the work of the cross-functional working groups. Their efforts are greatly appreciated.
Presentation
The Code is divided into numbered sections, each dealing with some key aspects of the work. Sections 0 to 16 and 26 are considered general sections and the remaining sections complete or modify the general sections. The sections are divided into articles whose titles facilitate the consultation:
Dialing Network - With the exception of section 38, even numbers are used to identify sections and sections of the Code. The article numbers consist of the section number, separated by a dash of a 3 or 4 digit number. This approach allows the use of odd numbers for new items to be inserted into the Code as a result of revisions made between two publications. Due to the introduction of some new articles and the deletion of some existing articles, caused by the revision of each edition, the numbers of the articles relating to any particular prescription sometimes differ from one edition to another.
Subdivision of Articles - As in sections 8-204 and 8-206, the other sections of the Code are subdivided and identified as follows: 

00-000 | Article

1) | Paragraph

a) | Paragraph

(i) | Paragraph

A) | Paragraph


Reference to other articles, etc. - When referring to several other articles (eg, items 10-200 to 10-206), the first and last articles mentioned are included in the reference. When referring to a paragraph or a paragraph within the same article, it is sufficient to indicate the number of the paragraph or the letter of the paragraph preceded by the word paragraph or paragraph. If reference is made to another article or section, the number of the article must be specified and preceded by the word article [p. Article 10-200 (3) and not (3) of Article 10-200].
The main changes to the 2015 edition of the Canadian Electrical Code, Part One from the 2012 edition are indicated by the delta (?) Symbol in the margin. All changes are not indicated. The symbols are meant to help the reader, but they are not a guide to changes. It is therefore important not to rely solely on the symbol to identify changes. Users should consult the entire Code as well as any changes or interpretations of local authorities. 

Application domain

This Code applies to all electrical work and to any electrical equipment that operates, or is intended to operate, under all possible voltages in the electrical installations of buildings, structures and properties, including prefabricated movable and non-movable buildings, and self-propelled boats that are immobilized for periods of more than five months and are continuously or occasionally connected to shore power supply with the exception of: 

• installations or equipment used by a public electricity, telecommunications or cable distribution system operating as such and recognized by the relevant regulatory authorities and located outside or inside buildings, or parts of buildings reserved for that purpose
• equipment and installations used for the operation of electric railways and supplied exclusively by circuits supplying the motive power
• installations or equipment used by railways for signaling and telecommunications purposes and located outside or inside buildings, or parts of buildings reserved for that purpose
• aircraft
• ship power systems under the jurisdiction of Transport Canada

See also CSA M421 for mines and quarries. 

The fact that an authority adopts this Code and the reference works does not mean that it guarantees or ensures the service life, durability or continued operation of the equipment and materials concerned.

C22.1HB-F15 - Explanatory Guide to the CCC, Explanation of the Canadian Electrical Code Articles, Part I
Introduction to the Guide explanatory note
This Guide contains documentation on the rationale behind the requirements of the Canadian Electrical Code, Part One, and explains the articles in plain language that is easy to understand. The Guide aims to facilitate a better understanding of the Code's security requirements. 

The Guide was not written to constitute a code of mandatory requirements. In the CCC, Part One, the word must indicates a prescription, but when used in this Guide, the term does not have the same value; it serves here to simply support the requirements that are set out in the Code. It was ensured that the purpose of the articles was clear to the users of the Guide. However, under no circumstances should users of the Guide refer only to the Guide to determine the current requirements of the Code. It is understood that this requires references to the same Code and any local amendment. CSA does not assume responsibility for any errors or omissions that may be found in this Guide. 

The articles of the Canadian Electrical Code, Part I are divided into two groups. Sections 0 to 16 and 26 are considered general sections while the other sections are complementary, or modify these general sections. Thus, a requirement found in a complementary section takes precedence over a general requirement. 

For example:

for a threaded connection, Article 12-1008 requires the penetration of three nets while Article 18-106 requires five in a Class I area 1 area.

Section 4 allows the use of conductors aluminum but Article 32-100 does not allow the use of aluminum conductors in fire alarm systems.

2015 ELECTRIC QUICK REFERENCE GUIDE

Preface

This is the second edition of the Electricity Quick Reference Guide, published by CSA Group. This is a manual that goes hand in hand with the 2015 edition of the Canadian Electrical Code, Part One. 

The Electricity Quick Reference Guide directs readers to the most frequently cited items in the Code and other useful information for staff who often work on the job. Most information is presented in easy-to-read tables. The Electricity Quick Reference Guide also provides some basic information about electricity terminology and work methods. The final sections include basic tables that summarize various commercial sizes, standard ratings, and equivalencies, as well as excerpts from the most frequently accessed tables and schemas in the Code. 

The Electricity Quick Reference Guide is a compact and easy-to-read on-the-job tool, so its content is not complete; it should not be considered an equivalent of the Canadian Electrical Code, Part One. CSA Group assumes no responsibility for any errors or omissions that may result from the information contained in this publication. 

Some of the changes to the 2015 edition of the Canadian Electrical Code Part One are included in this edition of the Quick Reference Guide to Electricity. These changes include the following: 

a new way of establishing how to use the terminating temperature of an equipment to establish the normalized conductor temperature when calculating the maximum ampacity of the conductor;

new correction factors to be used to determine the maximum ampacity of drivers under certain conditions;

new tables to be used to determine the minimum size of the continuity conductors;

the addition of Table 39 to be used to determine the minimum size of three-wire service conductors suitable for 120/240 V and 120/208 V for single dwellings and arterial conductors supplying row house units and similar buildings;

the addition of requirements for class A and class B cable ducts;

the addition of requirements for metallic electrical tubing for wet locations or outdoors;

the addition of Tables 6A to 6K to be used to determine the minimum size of conduits or tubes when all conductors are the same size, are suitable for the same rated voltage, and are protected by the same type of insulation;

the addition of requirements for arc protection in the power outlets in homes and dwellings;

the addition under the column of full load currents in Table 44 of column 208 V for three-phase motors; and

the addition of Table 68 to be used to determine the maximum length of conductors used in housings, measured from the power supply side of the consumer's connection to the farthest point of use on a single-phase 120 VAC (two-wire circuit) with Copper conductors suitable for 90 ° C at an ambient temperature of 30 ° C.
