Which code governs electrical installations in Canada?

1. National Electrical Code (NEC)

2. Building Code of Canada

3. Canadian Electrical Code (CEC)

4. International Electrotechnical Commission (IEC)

The correct answer is: Canadian Electrical Code (CEC)

The Canadian Electrical Code (CEC) is the governing standard for electrical installations throughout Canada. It outlines the necessary safety regulations and requirements for electrical systems, including wiring methods, equipment installation, and maintenance practices to ensure safety and reliability. The CEC is adopted at the federal level and enforced by provincial and territorial authorities, thus providing a unified standard that applies across the country. The National Electrical Code (NEC) is specific to the United States and, while it may influence some practices in Canada, it does not govern Canadian electrical installations. The Building Code of Canada focuses more on structural and safety regulations regarding building construction rather than electrical systems specifically. The International Electrotechnical Commission (IEC) develops international standards, but these are not governing codes for electrical installations in Canada, where the CEC is the primary source of regulation.
