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.
