I'm trying to add an outlet from 2 wires that are just hanging out of the wall. I followed the wires to the attic and only one wire goes to the attic. The other wire went somewhere else.
I tested the wire and found out that it's either a ground or a neutral. How do I find out for sure if this is a "ground" or "neutral". If it's a neutral, then this outlet I'm trying to add is almost complete. If it's a ground then I'm in for another few hours of work.
Thanks, stan
