Are there any articles/papers that explain the need or benefit for a dedicated circuit(s) for one's system? Several sources indicate a dedicated circuit, preferably a 20A circuit, or multiple dedicated 20A circuits is the way to go. My home is already built, and I have a 15A circuit to my dedicated system room, an office, a bathroom and hallway light. In the 15 months I've had my system, I've used all these rooms the way I want, at the same point in time, and have never had any problems. I have no ground loops, no strange noise, and no strange lines in my plasma. So I'd like to understand why it is so commonly suggested to spend the $$ to have a dedicated 20A circuit installed. What will my real world benefit be? My Panamax, whether watching a DVD with lots of low frequency, or watching TiVo, or in any circumstance, only reads between 2.2A and 2.5A. I'm hoping there's a great paper I can be referred to that will clear all this up.
