Krell Evolution 402e tripping breaker

[Audiofn]

I have a Krell 402e that is tripping the internal breaker. It will run for about a half hour or so and then the breaker will trip and it will shut down. Does anyone have the schematics? Also any thoughts about what a common cause may be? It sounds perfect up to the point of it tripping. The more it warms up the faster the breaker will trip.

The peak power consumption of the 402e is 3800 watts. Given AC circuits, this would be an average ( I think ) of 22 amps, and a peak of 31 amps

How do you have this plugged in? Do you have a dedicated power line for it? Or do you have it plugged into a 15A breaker with a bunch of other stuff?

I just edited the post. It is tripping the internal breaker at the back of the amp not the one feeding the amp. It is plugged into a dedicated 20 amp.
