An easy way to tell is to hook a simple 2 wire iduction motor across the
lines. If it starts, it is 2 phase, if not single phase. The single
phase motor needs some means of starting such as a capacitor start
circuit. That was one of the reasons 2 phase power was used.



I ment to say 3 wires , not 2.
