Thanks all who chimed in much appreciated and have given the go ahead on the CH panel. Another question has popped up—we have a 400amp service and the electrician wants to use two 200amp panels—one for those circuits served by a 24k Generac propane generator and one for the other circuits in excess of what the Generac can handle. I would prefer using one panel as we have in our current home (200amps). Since we need more than a 200amp panel in the new home I am wondering if we could do a single 300amp panel rather than 2 x 200amps. If I need the full 400amps and two separate panels would you put the audio room circuits on the panel served by the generator or on the other panel? FWIW the generator is outside the audio room so the noise of it will make it unlikely I will listen to my system during power outages.
@n0m1n4l I prefer multiple dedicated lines so I can avoid using a power conditioner—better to draw straight from the wall if possible in my view.
