What Are Electrical Codes?

Electrical codes are a collection of guidelines that dictate how electrical systems should be installed and maintained. These codes ensure that electrical installations are safe, reliable, and efficient. In Ontario, the primary code is the Ontario Electrical Safety Code (OESC), which is updated regularly to accommodate technological advancements and emerging safety concerns.

The Role of the Ontario Electrical Safety Code

The OESC is a critical document that outlines the rules for electrical installation and maintenance. It is essential for electricians to be familiar with this code to guarantee the safety and legality of their work. The code covers a wide range of topics, including wiring methods, grounding, and bonding, as well as specific requirements for different types of buildings.
