3 Phase Service – Vancouver Electrician FAQ

I have a motor rated at 220V single phase I’m using at home in my workshop can I use it in my commercial workshop that has a 120/208V three phase service without damaging the motor?

Yes. 208V is a standard three phase voltage. The 220V rating of the motor allows it to be used in both a 240V single phase system as well as 208V system. You will not have quite as much power as you would when you were using it at home which provided you with a 120V/240V service but will likely not notice the difference. By the way 208V will actually give you a measured voltage probably closer to 210V-215V.
