we just got an air compresor from an old body shop. it sounds like it is 2 phase. is this 120 hot- 120 hot for 220 wirth no nutral? if not how is it setup. somthing i read said most american houses only have single phase service however i think thats wrong. at least in our area there are 3 wires to most every house. 2 insilated hots and a bare nutral. is'nt this 3 phase? so 2 phase should just be 120-120 with no nutral.
