Electrical Power - Dedicated Runs
We are considering purchasing some MTRX2 monos. They each need a 30A dedicated circuit. MSB states the following:

Using the 30A connector is consistent with the de-rated line recommendation. You might also want to consider that if you feed branch circuits off of this de-rated line spur, you will not be able to safely use any panel breaker that exceeds the capacity of those branch lines. So that may leave you with a 15A circuit. IMO, nothing beats proper, dedicated lines as a starting point for AC power. I think your next step is to clarify the manufacturer's recommendation. The $1 million question: How much does each amplifier draw at rated power output? I don't see that listed in the online specs.

Plus 1 to Cleeds. How often will you run the amps at their max rated power? Under normal listening conditions they will use very little current.

Thanks guys. That’s very helpful.
I already have 3 dedicated 20 A lines run. That’s what they are currently plugged into. It was suggested to me to go down to 6 gauge wire for most of the run and then tie into the 10 gauge wire that I already have run. The electrician will be here tomorrow so I’m trying to figure out what needs to be run. It’s only an estimate, but …

Frankly I think you are in fine shape right now, power wise. 10AWG should be a-ok, unless m-a-y-b-e you have a really, really long run from panel to outlet. Maybe.

Thanks again. I have about a 50-60 ft run.
