Bringing a house closer to code for impending sale. (1) So, the receptacle in a wet bar is 26 inches from the faucet. Needs a GFCI. Opened a the receptacle and got a surprise. The hot side of the receptacle had one black and there one neutral on the other side. Usual. BUT ... what might be the Load side had one black and TWO neutrals. That is a new one! There is a light switch in the box. (2) In the kitchen, I opened another receptacle that looks like it should be at the front end of the circuit run. Again, thinking to add a GFCI. This time, there are two neutrals but THREE hots. How does this work? How can I add the GFCIs as intended?
