Mono blocks on different phases of the sub panel?

Thanks Albert. I'm building a new sound room with a dedicated sub panel. My plan was to run the video stuff on one phase and the audio on the other. I think I'll stick with that. I just read that article and it got me thinking. What panel/breakers/bus bars did you use with your system?

When I did my room, I had the electrician put all the audio lines on the same phase leg opposite the leg running the appliances and HVAC system. While he was rewiring the panel, he moved anything that might induce noise (Lighting on dimmers in the audio room and other rooms, fans, washer, dryer, hot tub)to the phase leg opposite audio if it was not already set up that way.

Looks like you, Slipnot1 and I all have the same idea.

As for panel, I went with the Square D that uses bolt in breakers (as opposed to snap in) and it has copper bussbars.

Let us know how you do with it.

Ditto Albert! I have the Square D w/bolt ins as well. I neglected to say that all four lines are pulled to Porter Ports on bright orange 10 gauge.

I also agree that any audio equipment that is connected together by ICs should be fed from the same Line, leg, of the electrical panel.

I do respectfully disagree with moving all induction motor loads to the other Line of the panel. This can cause an more than normal unbalanced load on the electrical panel, the service wire feeding the the panel, and the load on the utility power transformer. By having all the induction loads on the same leg this can lead to over heating of the main Ac power electrical system.

I would suggest balancing the motor loads evenly across both legs as close as possible. Also I would suggest keeping the branch circuit breakers for the audio equipment a few spaces away from the motor load branch circuit breakers.

Here you will find how a typical utility transformer works. Notice for a 3 wire single phase electrical service only the unbalanced load, (amps), returns on the neutral conductor back to the source. The remaining balanced loads are in series. What that means is some of the flow of current traveling though the motor loads is also traveling through the audio equipment power transformer's primary windings.
