Craig,

12 Gauge as a rule will handle 2400 watts I.e. 120V x 20 amps. You have 220V which is basically (2) 110V x 6 amps in single phase.

Do you have the 3 phase converter?

So if 110V (6) amps =660 watts peak load on each phase times (2). You would be fine with 12 gauge wire if it is already their. If you are going to wire the supply yourself, I would spend a bit more for more service in proximity to the mill. Eventually and grinders or lathes located near too? You may want to go to and 8-6 awg Gauge.

The phase generator is a noisy spinning frequency generator and can be wired at the mill.

You will be fine either way, but make sure you have an adequate ground to earth copper stake close by. When you run extended length of wire the potential resistance accumulates to a point where your body has less resistance that the conductor and you can potentially be the ground circuit in the event of a problem.

Hope that helps!

Bob
