The Canadian Electrical Code, CE code, or CSA C22.1 is a standard published by the Canadian Standards
Association pertaining to the installation and maintenance of electrical equipment in Canada.
The first edition of the Canadian Electrical Code was published in 1927.[1] The current (21st) edition
was published in 2009. Code revisions are now scheduled on a three-year cycle. The Code is produced by
a large body of volunteers from industry and various levels of government. The code uses a prescriptive
model, outlining in detail the wiring methods that are acceptable. In the current edition, the Code
recognizes that other methods can be used to assure safe installations, but these methods must be
acceptable to the authority enforcing the Code in a particular jurisdiction.
The Canadian Electrical Code serves as the basis for wiring regulations across Canada. Generally,
legislation adopts the code by reference, usually with a schedule of changes that amend the code for
local conditions. These amendments may be administrative in nature or may consist of technical content
particular to the region. Since the Code is a copyrighted document produced by a private body, it may
not be distributed without copyright permission from the Canadian Standards Association.
The Code is divided into sections, each section is labeled with an even number and a title.
Sections 0,2,4,6,8,10,12,14 and 26 include rules that apply to installations in general; the remaining
sections are supplementary and deal with installation methods in specific locations or situations. Some
examples of general sections include: grounding and bonding, protection and control, conductors, and
definitions. Some examples of supplementary sections include: wet locations, hazardous locations, patient
care areas, emergency systems, and temporary installations. When interpreting the requirements for
a particular installation, rules found in supplementary sections of the code amend or supersede the rules
in general sections of the code.
