Parts of the Canadian Electrical Code

The Canadian Electrical Code has helped provide safe electrical installations in Canada for nearly a century. You can read more about the latest revision of CSA C22.1 in our post on the standard.

However, CSA C22.1-2021 is only Part I of the Canadian Electrical Code, one of five parts that each serve different interests.

Part II of the Canadian Electrical Code is focused on evaluating electrical equipment. CSA C22.1-2021 actually specifies that electrical products are approved to a standard document in Part II. And, Part II includes not just a single standard like Part I does, but hundreds. In fact, there are so many standards in the CSA C22.2 series that we couldn’t list them all here. Some of the more popular ones are:

CSA C22.2 No. 120-2013 (R2018): Refrigeration equipment

CAN/CSA C22.2 No. 61010-1-12 (R2022): Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 1: General requirements (Tri-national standard, with UL 61010-1 and ANSI/ISA-61010-1 (82.02.01)

For all available CSA C22.2 standards, please search the ANSI Webstore. If you can’t find a specific document for your occupation or compliance duties, please feel free to email us at, message us on Facebook, or Tweet at us, and we’ll do our best to help you out.

Part III of CSA C22 is focused on power distribution safety. It is made of not one but the following standards:

CSA C22.3 No. 1-2020: Overhead systems

CAN/CSA C22.3 No. 3-98 (R2022): Electrical Coordination

CSA C22.3 No. 4-1974 (R2020): Control of Electrochemical Corrosion of Underground Metallic Structures

CSA C22.3 No. 5.1-93 (R2022): Recommended Practices for Electrical Protection – Electric Contact Between Overhead Supply and Communication Lines

CAN/CSA C22.3 No. 6-13 (R2022): Principles and practices of electrical coordination between pipelines and electric supply lines

CSA C22.3 No. 7-2020: Underground systems

CSA C22.3 No. 9-2020: Interconnection of distributed energy resources and electricity supply systems

CAN/CSA C22.3 No. 60826-2019: Overhead Transmission Lines – Design Criteria (Adopted IEC 60826:2017, Fourth Edition, 2017-02, With Canadian Deviations)

CAN/CSA C22.3 No. 61936-1-2018: Power installations exceeding 1 kV a.c. – Part 1: Common rules (Adopted CEI/IEC 61936-1:2002, first edition, 2002-10, with Canadian deviations)

Part IV was published in 2009 due to industry demand to create an objective-based industrial code. It is intended for an authorized user—“an organization recognized by the authority having jurisdiction and responsible for establishing, documenting, implementing, and maintaining the requirements of this Code and continually improving its effectiveness.” It contains one document:

CSA C22.4-2009 PACKAGE (R2018): Consists Of C22.4 No. 1-09, Objective-Based Industrial Electrical Code And C22.4 No. 2-09, Objective-Based Industrial Electrical Code – Safety Management System Requirements

Part VI of CSA C22 is focused on performing electrical inspections of existing residential buildings. It comprises one standard:

CSA C22.6 No. 1-2011 (R2019): Electrical inspection code for existing residential occupancies
