Dedicated 20 Amp Line for Audio

I am currently in the process of doing this wiring and in fact just today installed the 20 amp breaker in the panel and pulled and tacked the 8-gauge from the box up through the attic and to the wall where it will come down to the entertainment center.

I still need to come down through the wall and will probably just cut and remove the old 15 amp wire and use that as the wire pull through the wall.

All plugs are 20-amp hospital grade (with the green dot) and will accept the 8-gauge wire.

We have solar panels and an inverter. I’ve heard that these can add noise on the line. I put a ferrite bead over the wire right where it comes out of the panel. May not help anything..., but couldn’t hoit.

I installed a single 8-gauge, 20-amp line/breaker with the thought that if all of the equipment is on the same source, neutral, and ground, it should be less likely to hum or develop ground loops.

If one were to pull two lines from the two busses, which line would you use to ground a metal outlet box, or would you use both grounds on the box???

Well we did it today. The run was 121’ of 8-gauge wire, with another 2 feet to run between the plugs. Seeing as how I had a 125 foot spool of wire, I cut it pretty close!

It is not easy, but not impossible to feed in and jumper the 8-gauge between two hospital plugs in the dual wall box, but using the deep box, we managed.

I also ran RCA panels with six leads from the inside to the outside of the entertainment cabinet to allow me to access various aspects of the system from outside of the cabinet. For example, this would let me bi-amp if I so desired.

Just need to mud a couple slots in the drywall and paint now.
