Jea48, the bare wire is the ground. It is connected to the ground bar in the panel and at the outlet it is connected to the box and outlet ground screw
Time for dedicated outlets!
I would like some advice on what exactly to tell my electrician to be sure I get what I need. Is just saying that I want two separate dedicated lines to the listening room sufficient or are there other key fraises that should be included in my description of the work I would like done?
