Amp and preamp on same outlet?

Jea48, I do not understand why you would make humor of the truth, I had numerous others with the Krell 750MCX mono block's and the stereo Krell 700cx say the same thing, they encouraged me to use the 30 amp breaker as did krell them selfs,no one knows it all, we all learn from each other, I did not believe that the 30 amp breaker would do any thing either, but when I got 20hrs of break-in on the breaker, it turned out to be the best cheap tweak ever I have done in my life time, the benefit's was worth thousand's of dollar's to me!

Jim, you do not understand, Krell runs 30 amp braker on every krell 700cx, 750mcx amp there at the factory, BTW, I have 4 fuses, well with-in the current capability useing a 30 amp breaker, as I said befor, I am not useing all the 30 amps!,however, This amp in particular spikes well above 20 amps while in use, maybe you should call krell, then you will get all the theory as to why this works properly you want, remeber, this amp at full power is 6,000 watts!

Help me Jim or Al, I don't know if my math is right, but isn't 6,000 watts equal to 50 amps on a 120 VAC line?

John, yes your math is of course correct. And the 700cx does indeed have a max power consumption spec of 6000 watts, which if anything seems a bit low in relation to its specified output power rating of 2800 watts/channel into a 2 ohm load (the 8 ohm and 4 ohm ratings being 700 and 1400 watts respectively).

But it seems safe to assume that it would be an unusual occurrence for the amp to be used in a manner that would require it to draw more than 20 amps x 120 volts = 2400 watts for a long enough time to cause a 20 amp breaker to trip.

Best regards,
