Using a generator

If you use a generator, follow the rules for installing and using your generator:

  • Have a qualified technician connect your generator to your home’s electrical system through its panel and transfer switch.
  • Place the generator outdoors in a ventilated area and away from doors and windows (not in a garage). This will prevent exhaust fumes from entering your home.
  • Make sure it is firmly fixed to the ground.
  • Connect lights and appliances directly to the generator. If you use extension cords, they must be of the proper gauge and approved by the Canadian Standards Association (CSA).
