Ontario Electrical Safety Code (OESC) 27th Edition
Ontario Electrical Safety Code 27th Edition
Please be advised that an unintended omission from the Canadian Electrical Code (CE Code) has been identified. Due to this oversight, ESA is reinstating the existing Ontario Electrical Safety Code version of Rule 10-808 in its Recommendation to the Ministry of Government and Consumer Services. It is included as Rule 10-611 Installation requirements for bonding conductors.
Rationale: During the CE Code approval process led by the Canadian Standards Association (CSA), Rule 10-808 (installation requirements for bonding conductors) was unintentionally excluded from the final Section 10 approval document at the national level (CSA).
During the development of the 2018 Edition of the CE Code, Section 10 was rewritten and reconfigured in an intuitive and user-friendly format. During this process, Rule 10-808 was unintentionally excluded in the final version and, as a result, the CE Code 2018 (national-level) does not contain the safety requirements related to the installation of bonding conductors.
This Rule was originally introduced in the CE Code in 1972 and has evolved over time as required. The Rule was initially introduced to set important safety requirements regarding the installation of equipment bonding conductors.
CSA is taking steps to correct this unintended omission through a proposal to restore this requirement for CE Code 2021. In the meantime, to mitigate risks associated with this gap in guidance, ESA has included the 2015 version of Rule 10-808 in the CE Code as an Ontario-specific amendment.
Rule 10-808 has been renumbered to Rule 10-611 in the 2018 Ontario Electrical Safety Code.
ESA thanks all stakeholders who submitted comments and feedback during the public consultation for Ontario Amendment (OA) proposals.
The below resolution sheet reflects the comments received along with resolution. The revised proposal drafts are based on ESA’s review of the feedback received during the public consultation and discussion with Ontario Provincial Code Committee (OPCC).
Once the overall adoption of the Ontario Electrical Safety Code (OESC) “27th edition” is endorsed by ESA’s Board of Directors, The proposed changes will be submitted to the provincial Government for review and approval.
ESA is recommending to the provincial Government that the OESC 27th edition come into effect May 2019.
The Electrical Safety Authority (ESA) is reviewing the Ontario Electrical Safety Code (OESC) requirements to ensure the regulatory framework provides the appropriate balance between the need to ensure safety and supporting modernization and eliminating unnecessary encumbrance on industry.
ESA sought the views of contractors, consumers, businesses and other stakeholders on all proposed amendments to the Ontario Electrical Safety Code. The consultation ran from Tuesday March 6 to Friday April 20, 2018.
