I am installing a new compressor for a customer. His shop is 2-phase 5 wire (4 hot 1 neutral) but the new compressor is single phase. I mainly do commercial and light industrial work, but I have never come across 2 phase. Even though I sort of picked up on the basics I'm still unfamiliar with it so hopefully someone can help me out. I need to get the 2 phase supply to the single phase compressor. Can I just use one leg or is there a transformer I need?
I think a 5 wire setup is just a split winding on either of the two phases with the whole advantage being that it can run single phase loads. If you measure from any phase to neutral, do you have 120V?
