Will a GFCI work correctly without a grounded wire?
Electrical is something I don't pretend to know anything about. So, I'm here asking this question because DH and I had two electricians tell us different things regarding GFCIs. We just bought a "new" old house. Electric needs to be updated. One electrician said GFCIs need to be used with grounded wires, which we don't have in most of the house. The other electrician said GFCIs will still work without grounded wire. Not sure who to believe. Please help!!!
