To clarify . . . each receptacle will have it's own circuit. I was just trying to find out whether to use 10/3 or 12/3.
Caselec . . . if all anyone needed to achieve an "isolated" ground was just a dedicated circuit and a receptacle, then why do people even bother w/ a true Isolated Ground receptacle. I've been following a Black & Decker book for home wiring that suggests IG circuits for computers and sensative electronic equipment . . . it says IG circuits "provide extra protection against power surges that can hram equipment." Also, every studio I've been in has them.
So are you saying that connecting the bare wire of 12/2 cable to the grounding screw of a receptacle mounted in a plastic box offers precisely the same protection a 10/3 IG circuit?
They would perform precisely the same?
As far as hiring an electrician, I may hire one . . . I spent $300 a year ago having an electrician install 3 dedicated circuits in my other house for my audio. It seemed like alot of money, but I wanted it "done right." About a week later I flipped on a light switch and noticed a pop in my speakers (which were powered by one of his dedicated circuits). So I spent all that money for good expertise to achieve isolation and I didn't end up getting any. So that is one of the reasons I am on this forum . . . to learn how to do it right. And there seems to be more than one way to do it.
After reading the B & D book, installing a new breaker and pulling cable for a circuit seems to be within the capability of a prudent home owner (at least the book says so).
If I do the work myself, rest assured it will be thoroughly researched . . . I won't do anything I don't think is within my abilities.
Thanks,
Mike
