Well, same outcome, just not with the typical terminal studs and straps etcWell this in the OP threw me!
The way it is now, is identical to if you strapped across U2, V2, W2 in such a box, thus bridging/bonding for a Star/Wye configuration.
I'll rewire it in Delta and see how the winding resistance compares, get some sort of ballpark on the current flow will be under 415V 3P and see if it looks reasonable for the field winding wires (which are pretty small, but I guess it's only 360w motor after all). If that all looks like it won't immediately produce nuclear armageddon, then I'll hook it up to power and see what happens.
