Question for the electrical-minded.
I finished steaming any remaining cigarette residue out of the wall and am ready to hang my new wall sconce. It can be hard wired or plugged in. They recommend using an electrician for both but I've hung track lighting before and I figured "how hard can it be." I'm not stupid enough to try hard wiring on my own but plug in I can do.
So I undid the 4 screws and removed the back. And there was a little, green nut screwed into the backing (the tip keeps the backing from lying flat on the wall) and it says "ground." That's only for hard wiring, right? If I have to ground this thing, I'm getting an expert.
