The Ontario Electrical Safety Code
Ontario Electrical Safety Code (27th edition/2018)
ESA has collaborated with its safety partners to produce a new edition of the Ontario Electrical Safety Code (Code). The Minister of Government and Consumer Services has approved the regulatory amendment to adopt the 2018 Ontario Electrical Safety Code, and it will come into effect on May 16, 2019. Electrical work conducted after the effective date needs to meet its requirements.
The 2018 edition of the Ontario Electrical Safety Code –which includes the Canadian Electrical Code Part 1 plus several Ontario-specific amendments – reflects changes in technology and the marketplace, and incorporates feedback from stakeholders, technical reviews and new safety insights. The new edition includes changes designed to enhance electrical safety and protect workers and the public including:
- Re-write of Section 10 requirements for bonding and grounding have been reorganized and reduced in size with some changes that will improve safety and simplify the installations;
- Expanding the use of Tamper-resistant receptacles in educational facilities and hotels/motels;
- Requirements for installing an identified (neutral) conductor at each control (switch) location of permanently installed luminaire;
- Alignment with the Ontario Building Code to prevent the installation of high-voltage conductors over buildings;
- Providing of adequate working space for electrical workers to undertake necessary repairs, maintenance and installation of transformers greater than 50kVA;
- Prohibiting of installation of cables in concealed locations in corrugated roof decking
- Adding requirements for Energy Storage systems; and
- Facilitating the use of Power over Ethernet to provide a pathway for sources of electricity.
All Ontario-specific amendments included in the 27th Ontario Electrical Safety Code can be found here on ESA’s website.
ESA is partnering with the CSA Group to offer the Code book and all ESA bulletins – which provide important updates and interpretations – together for one price. It will be available in print for $219 or a searchable, digital format for $195 – accessible on smart phones, tablets and desktops and compatible with Windows and iOS. (Please note: bulletins are available electronically. After purchasing the Code book, register at CSA Communities to access the bulletins online.)
About the Ontario Electrical Safety Code
The Electrical Safety Authority is designated by Ontario Regulation 89/99 as the responsible authority for purposes of section 113 of the Electricity Act, 1998 and regulations made thereunder. The only such regulation is Ontario Regulation 164/99 as amended by Ontario Regulation 10/02. This regulation adopts, by reference, the Canadian Electrical Code together with specific Ontario amendments and is referred to as the Ontario Electrical Safety Code (Code).
The Ontario Electrical Safety Code is primarily a technical document and it is prescriptive in approach. The Code describes the standards for electrical installations in detail.
Risk associated with technical compliance can be decreased by taking appropriate measures to ensure that those who perform electrical work are qualified, competent and appropriately certified or licensed.
The Code is developed through the efforts of a number of committees representing electrical expertise and knowledge from across Canada and the U.S. The Ontario Electrical Safety Code is law in Ontario, and as such defines the legal requirements for safe electrical installations and products/equipment in Ontario. Changes to the Code are documented on an ongoing basis.
