I'm a residential electrician which = single phase so I'm all confused and junk... I'm trying to wire up my mill which is 3 phase 220. I'm running a rotory phase converter with T1, T2, and T3 outputs. The mill has it's main breaker with the 3 lugs and a ground lug for an earth ground rod. Anywho, how do I know which leads go to which lug on the breaker? It's not labeled at all so... Does it matter?
