Wiring is speced by our National Electric Code. However, you have some options. I recommend a dedicated 20 amp isolated ground circuit to a quad (double duplex) outlet. Dedicated means that there are no other faceplates on that circuit breaker (it is common to wire up more than one faceplate to one circuit). 20 amp means the breaker and wire used can carry more current than a typical 15 amp circuit. Isolation grounding means that a different wire type is used to carry the back-box ground to another grounding point on the breaker box. This usually provides better isolation from noise. A single circuit such as this in my home in Philadelphia cost about $100.
AC Polarity
I'm in a house that is about 75 years old and have a pretty nice system (Muse, NAD, Martin-Logan, etc.) along with my TV, VCR's, etc. and am going to replace the prewar electrical outlets in my living room. What I'd like to know is which side of an outlet is the 'hot' side. I am wondering if electricians wire all outlets the same way, say, putting the 'hot' on the side that has the slot for the wide blade on a modern 3 wire outlet. Any info welcome.
