I was talking about running another 12/2 line from the dedicated 120 amp (daisy chaining) to the receptacle mounted in the ceiling at the projector, not plugging into the same receptacle. Correct me if I'm wrong, like I said before, I know nothing about electrical work but if I run another line off of the dedicated 120A line to get power at the receptacle at the projector, wouldn't the projector and the HTS 5100 share the same ground then? I just think this would be a much cleaner install compaired to running an extension cord threw the ceiling then out the wall and plugged into the HTS 5100.
