That's something I haven't done yet, I'm used to A,B,C, 4-7 , 5-8 , 6-9 or even some other ramps from VFD, the leads are always there and labeled though, transformers pre tapped etc, lol. So what would I expect to get for values and are you saying that the windings should all be in series for the 230 Volt? that's what I want to draw about half the amperage, and the windings would be parallel for the 115 volt hook up? So explain how the path goes in a 480 circuit, I thought I figured it out but it seems like what I was thinking would make a parallel circle, lol.
