I am looking to make add a dedicated circuit to my panel for all of my media gear in my bonus room. Reason is that the room is mixed use so part of it is the office and the other part is the media room. Currently this is all being run on one circuit. At the moment I have 2 computers, 1 htpc, 1 server, printer, monitors, receiver, xbox, wii, subwoofer, projector and lamps all being powered off of this circuit.
I have room in my panel to add the circuit and accessing my panel won't be an issue as I have access to run the wire to the panel to the room through the attic. One thing I am curious about is how to run the romex wires. Since this is a finished room it has insulation all around the room along with some thermo-ply behind the insulation. Do I need to run the romex wire in a conduit or through the studs or can I just run in along the thermo-ply?
