Product Details
Preface to the 26th edition of the Ontario Electrical Safety Code
This edition of the Ontario Electrical Safety Code contains the standards referenced by the Ontario Regulation made in 2015 pursuant to the Electricity Act regarding the Ontario Electrical Safety Code. Reference should always be made to these Regulations, and amendments thereto, as may be made from time to time.
This edition contains electrical safety requirements for wiring and equipment in buildings, structures, and premises, with the exception of mines, railways, aircraft, marine vessels, installations used for communication purposes, and automobiles.
As electrical hazards occur mainly because of overloading and abuse of wiring systems, it is recommended that initial installations be planned with adequate provision for possible future uses of electricity.
The 26th edition of the Ontario Electrical Safety Code consists of CSA C22.1-15, Canadian Electrical Code, Part I, and the Ontario Amendments to CSA C22.1-15, Canadian Electrical Code, Part I, dated October 2015. This publication contains both documents, with the following marking conventions:
A trillium indicates an amendment applicable in Ontario. The Ontario amendment appears in italics, just before the Canadian Electrical Code Rule(s) that it modifies.
A delta indicates a change from the 25th edition (2012) of the Ontario Electrical Safety Code.
A delta in the CE Code, a change from the previous CE Code (2012).
Note: Some small editorial errors found in the Canadian Electrical Code, published in C22.1-15 Update No. 1, were corrected in this publication.
