I've been planning for the install of an RPC. The schematics I see on google show bringing in the single-phase, and the third phase magically appears on a 3rd wire with the single phase wires representing the other legs. I have been taking it for granted. But an electrician (not familiar with RPC's) just made me think - he said "with single phase the 2 wires are 180 apart in phase. In 3 phase the 3 are 120 degrees apart. How can you use the same single phase wires as 2 of the 3 legs?
Good question. Can anyone shed any light?
