Usually it's the two HOT wires of the 240vAC (two 120 volt legs that differ in phase) and ground.

That's how our office compressor is wired, and how I plan to wire my home compressor.


This assumes its not a single phase 240VAC generator. And that you are in the USA or Canada.

Thanks. You are correct, the 240VAC Generator is 3Phase and we are in VT, USA. Is there a specific male adapter I could wire to the 208VAC Single Phase Winch Motor in order to be able to plug it directly into the 240VAC outlet on the generator ?

No, there is no such thing as an adapter.

Your motor is designed to run on 208v single phase. Your generator can provide 240v single phase from the three phase it puts out. Thing is the motor will not like the 240v for a very long time. Running it at 240v will shorten it's life.

Why not just get the proper motor?
