Preface
This is the fifth edition of CSA Group’s Electrical Code Quick Reference. It is intended to be used as a companion to the 2024 edition of the Canadian Electrical Code, Part I.
The Electrical Code Quick Reference directs the reader to some of the most frequently cited Rules of the Code and other information required by field personnel on a frequent basis. Much of this information is presented in tables that are designed for quick and easy reference. The Electrical Code Quick Reference also provides useful background information related to electrical terminology and procedures. The final sections contain basic tables specifying trade sizes, standard ratings, and equivalents, followed by excerpts from the most commonly consulted Code Tables and Diagrams.
The Electrical Code Quick Reference is designed to be a quick and portable reference guide in the field. Since the material is not intended to be complete, the Electrical Code Quick Reference is not under any circumstances to be used in place of the Canadian Electrical Code, Part I. CSA Group does not assume responsibility for any errors or omissions resulting from the information in this publication.
Some of the changes to the 2024 edition of the Canadian Electrical Code, Part I, are included in this edition of the Electrical Code Quick Reference.
