Ground loop question (household wiring question)

[Coytee]

I don't knowingly have any yet....but I'm not setup yet so this is a question about a hypothetical situation.

Setup: 200 amp panel feeding a 50 amp subpanel.

Off the subpanel, four 20 amp circuits dedicated to the HT system. One circuit will drop at the left front location, another at the center location another at the right front location and the last will be in the closet.

This will allow me to put all my amp(s) in the closet or, more likely, take an amp to each front location so they are near each speaker.

Will this breed ground loops? I have no idea.

Here's the question.... (aside from Code since I don't know what a code would say) would there be any merit in me stringing a ground wire from the front left drop to the center drop to the right side drop... in effect, allowing the three (different circuits) to share a ground across the front in addition to the common ground that they already share at the subpanel? I could also tie this in to the 4th circuit in the closet quite easily. I'm talking about a single 12g wire making a stop at each location on 4 different circuits.

Presuming code allows this, would this help anything or would it open another can of worms? I figure it's better to ask now while I'm in open studs than to be told of this "tweek" (if it is one) after drywall is up.

Coytee,

That extra ground wire might cause a ground loop.

That extra ground wire might cause a ground loop.

I gotta admit, that also crossed my mind.

My wife would suggest to you that I sometimes (hahahahaha) over-think things, usually creating more heaches for me (her).

Look up what a "technical ground" is

When you going to finish this.....it's been on the drawing board for two years, maybe three.
