Safety Codes Bulletin: Electrical Services

Notice 

Recent demands from residential landowners for the newest technologies have shown that these systems may pose a problem with existing electrical services. As we add to these existing electrical systems, there is a huge potential to see these services become overloaded. Unless these new electrical loads are calculated and considered before the start of the work, there is an increased chance the new device may overload the existing service panel, which would lead to an unsafe condition and pose a fire hazard to the occupants of the building. Even the installation of a new air conditioner may result in the existing electrical service becoming overloaded and require a service upgrade.

Safety Codes Services has also become aware that there are some new 100amp services being installed that may not even provide the safety factors needed to comply with the current Canadian Electrical Codes and services are being overloaded.

As a result, this Bulletin has been prepared to provide clarity on roles and responsibilities of Electrical Contractors to ensure compliance with the Safety Codes Act and its regulations.
