A while back, a guy came around asking about a furnace in this thread. He made mention of his "wild leg" 3 phase service that takes 2 wires and turns it into 3 phase for his shop. I thought he was mistaken until he posted the schematic from his electrical provider (attached).
If that's actually what's going on, could I use this setup to produce 3ph from my 220V household mains?
Why or why not?
How could this work? Would it actually create 3 phases that are 120 degrees apart?
Looking at the schematic provided, what I see is a single phase (2 phases of a 3 phase system) with a neutral, going into 2 transformers wired in some crazy manner that I don't understand, and supposedly 3 separate phases coming out.Basically, two primary wires come underground from a higher voltage run that is on a main secondary highway, about 1,000 feet behind my property to 2 outside transformers.
One wire feeds into a 15kva transformer, the second into a 25kva transformer, and they call this an open bank, (one missing) 3 phase power system.
