Reminds me of the fight I had with a restaurant owner about a dough mixer. Strange diagrams on the j box, not similar to any machines I'd done. Told him I had to call the mfr for info. He kept shouting "I told you it's 220!". I said "220 single phase or 3 phase, 220 with a neutral or without?" He shut up then, went off muttering. Turned out it could be connected from 208 to 480 single phase. I think it was a Vulcan. The local tech said he got calls all the time, that the diagrams were not clear at all & some covered voltages in other countries.

We later heard the owner absconded in the night with his $, and his partner's $.
