Isolated Ground?

[Jojitzo]

I have read a lot in this Forum about isolated grounds but none take you from start to finish.I am wiring a recording studio and would like to use isolated ground receptacles.Can anyone tell me from start to finish how to do this.I have full access to everything meaning all the walls are completely gutted.

Re: Isolated Ground?

Did you read the part about isolated ground receptacles being unnecessary in most instances and that they can actually cause problems?

Also consider that if you are using NM (Romex) and plastic boxes or metal boxes on wood studs you HAVE isolated grounds assuming the receptacle circuit is dedicated and originates at the panel, which it should anyway.

You might want to consider balanced power. Take a look Here.

Ty,

If you've read a lot on this Forum about isolated grounds, than maybe you've come to realize that there isn't much need for them. The popular opinion here is that they're basically useless. Solidly grounded receptacles should satisfy your requirements. I would use a cable that contains a copper equipment grounding conductor and not basic type AC cable which uses it's metal jacket as the equipment grounding conductor.

Re: Isolated Ground?

Use balanced power by Equi-Tech and eliminate the grounded circuit conductor all together.

But to answer your question if you have wood framing, sheet rock walls, NM cable, dedicated circuits, and plastic boxes you already have IGR as Hal pointed out.

If not then you need to use an shielded isolation transformer to start with. Then simply run dedicated IGR circuits where you need them. However if you were to go to that expense, just use balanced power systems and achieve even higher PQ. Follow that up by using balanced or optical signal transmission methods, and ground has no purpose other than safety.
