I have a room upstairs that's the size of a small studio apartment. My daughter decided to move back home but my tenant noticed that the room she moved into is tied into their apartment. I went to the panel box and noticed that there is a 12/3 wire in place.
My question is can I take the hot wire going to my kid's room and put it on my panel? Would it be ok with the ground and neutral still plugged into the other panel?
