How do I install a GFCI receptacle with two hot wires and common neutral?
I have a pool to protect correctly. There is a 12/3 wire: red serves the receptacles at the bottom of the pole lights and the black serves the pole lights. Now they are on two separate breakers. I was going to put a single pole GFCI on the receptacle line but I know that I can't share the neutral.
I see 3 options:
Can I put both the red and black on the same single pole? I think it is against code but would it work? I don't need the 20A for lights and the outlets.
Is the double pole option with the single ground right?
Wire the first outlet in the series with a GFCI .... but I'm not sure that works because the pole lights after it again share the same neutral.
I'm not pulling new wire ... It's underground.
