Electrical and Grounding Needs


Hello,

I have an electrician coming to my house this week. I have two outlets in my basement dedicated to my home theater setup -- but they are both on the same breaker. I ran the wire using 12/2 rather than the usual 14/2 thickness, thinking it would be better. Any thoughts on this? Also, he will be hooking a new sub-panel as I have run out of breaker slots, does anyone know of any special grounding considerations I should have the electrician take into account.

Also I will be using a Richard Gray 400s Power Plant on this line.

Thanks for any help in this matter!

Rives suggestion is an excellent one. Perhaps one suggestion to add to Rives: if you are able to convert your equipment, especially the amp to 230 volts, then you would not need a step down voltage converter. Instead, you would have some of the best AC you could practically muster. But this last step takes know-how and gonads but is cheap with excellent results.

Your electrician or perhaps Rives could best answer your question about isolated grounds.

I agree that the suggestions by Rives are good. The isolation transformer may be a tad expensive though.

If you do not use a transformer, the only way to get a true Isolated(in contrast to Dedicated ground)ground, is to have the electrician put an isolated ground bar in your new sub-panel, and run a separate ground wire that is not grounded to any thing else until it reaches your main house grounding point, where it will need to be connected per the National Electrical Code.

Then your electrician can install true isolated and dedicated grounds to each Isolated ground type receptacle you install. This will ensure a separate grounding path back to your main gounding point with no other grounds tied to it in-between to create noise.
