Two wire circuit...GFCI
I have a two wire receptacle in a hallway looks like grounded romex was used, but ground wire is not connected at the source (source is unknown). The next circuit in line is a bathroom outlet (next to the sink). This outlet was a three prong receptacle with ground not connected.
I plan on replacing the hallway outlet with a GFCI and then feeding the bathroom outlet via two wires. Is this kosher?
Or does the bathroom need to be fed by the GFCI with three wires? Also....is there anything about the GFCI having to be in the bathroom itself?
If I need three wires from the hall GFCI to the bathroom receptacle, I can fish a new romex if I have to.
