I agree with Bob Bundus and his suggestion on how many and what type of lines to run. I am not sure I agree about break-in of AC power lines (call me a skeptic if you will) and definately disagree about an isolated ground due to code violation and safety issues. Ground has to be tied back to the box somehow. Legally you can not have 2 separate and isolated ground systems being feed by one service. At least not here in New York.
How many dedicated lines?
I'm planning on running some dedicated 20 Amp power lines to my audio/home theater system. My question is how many separate lines should I run? I've heard of one audio system where every component practically had its own line. Is that overkill? Would two or three lines suffice for an entire system? In all, I have about 11 different components that need to be plugged in. Thanks for your help.
