I'm having a problem here at the house, I put two GFCI's on the same circuit (didn't know they were same circuit) and now only the first one (?) in the circuit (powder room) works, the 2nd GFCI (downstair bath) is next in line and no power on it, and then a few more (in master bath) have no juice either. I took the 2nd GFCI out and just tested the bare wires and still seems like no juice. ANy ideas?? I grounded out the downstair GFCI when testing it, is it possible to have actually burned out the wires between that and the powder GFCI??
