GFI Breaker wiring
I'm having an electrician swap out my FedPac panel for a GE(commercial, 3 phase instalation). In doing so, he didn't notice that two GFCI breakers were connected to the same 12-3 cable until he was installing the breakers and came up one neutral short. I thought it was impossible, but they worked before though we can't figure out how with a common neutral. The only thing I can think of, is when some previous owner went from a standard breakers to GFCIs, he ran a bootleg neutral for the second circuit.
We'll be trying to chase this down tomorrow. Does anyone have any other ideas what we could be looking for?
