You're really not connecting all that much.

2 circuits can introduce a ground loop problem.

I hooked up an amp probe to the circuit supplying my home theater, and I was seeing peaks of 18A. However, my HT setup includes:

5 Powered Subs (4x300W, 1x2700W) [heh, heh]
1 2x300W amp
1 1x300W amp
1 2x140W amp
Pre/Pro
65" RPTV
DVD
LD
VCR

and was producing in excess of 115dB to draw that much current.

At anything approaching sane volume levels, a 20A circuit was fine.

The little voices told me that soap is the hallmark of civilization.
