    Even very few commercial locations in the US have 3 phase, if you have it, you should know it, since you would have paid a large sum to have it installed.

    Look in your breaker box at top where main power switch is located. Three-phase switches have three legs and single phase units have two legs. So, it's either a double or triple breaker.
