If you own and manage a commercial building, you must ensure its electrical systems are safe. The current standard for electrical installation for commercial buildings in Canada follows the Canadian Electrical Code (CEC) and the Ontario Electrical Safety Code (OESC).
In this guide, we will examine the basics of the code and the importance of having an electrician inspect commercial buildings in Mississauga or your area.
Canadian Electrical Code (CEC) and Ontario Electrical Safety Code (OESC)
The CEC is the national standard that controls electrical installation practices across Canada. This covers many aspects of electrical systems, including wiring, grounding, overcurrent protection, and equipment standards.
The OESC is a provincial adaptation of the CEC that incorporates additional Ontario-specific requirements. It controls specific regional considerations, such as administrative processes, environmental factors, and equipment standards, ensuring that installations meet the province's safety and operational demands.
Both codes are implemented to reduce risks, enhance energy efficiency, and promote sustainable electrical practices in commercial spaces.
Key Electrical Code Requirements for Commercial Buildings
Below are the key electrical code requirements for commercial buildings to ensure safety:
Wiring Methods
● Commercial buildings should have sufficient wiring systems for heavy usage and environmental stressors.
● Ensure wires are in tubes or raceways to protect against mechanical damage, moisture, and other dangers. You can do this with the help of an electrician in Mississauga or your area.
● For durability and safety purposes, use materials approved by CEC and OESC, such as copper or Aluminum wire.
Overcurrent Protection
● Circuit breakers and fuses must be compatible to handle each load to avoid constant heating.
● Ensure overcurrent protection devices match the capacity of the equipment and circuits to avoid expensive damages.
Service and Panel Requirements
● Electrical service panels should have enough capacity to accommodate the existing and future electrical requirements.
● Electrical panels must be placed in accessible, well-ventilated rooms with ample unhampered space for maintenance and emergency operations.
● Circuit labelling and load balancing are essential to ensure the safety and efficient performance of the equipment.
Emergency Power and Lighting
● Buildings must have emergency lighting and power to allow safe evacuation and necessary operations during power outages. Hire an electrician in Mississauga to install emergency electric systems.
● Ensure engine backup generators, battery systems, and UPS devices meet reliability standards and undergo routine testing to ensure efficiency.
Grounding and Bonding
● Proper earthing reduces the risk of electrical shock, damage to equipment, and disruption of communication systems.
● Bond any metallic systems, like pipes and structural components, to achieve electrical continuity.
Why Electrical Safety Matters
Electrical safety is essential to protect a property and the people around it. Neglected or improperly installed systems can lead to fires, equipment malfunctions, and power outages. If you are a commercial building owner, following the electrical codes is legal and a proactive step towards avoiding risks.
