yes, most 50amp coaches with diesel generators only have a single 'BREAKER' that can be accessed/seen on the front of the generator, although there are actually TWO breakers - they are tripped together whenever one does, just like in the Main Panel of your RV. Resetting one also resets the other.
The reason there are two breakers on the generator for a 50amp coach is because the 'power' for each side is fed back to the RV's breaker panel, which, of course, has TWO Main Breakers.
For some diesel generators that put out 40-50amps, you might have a 30amp and a 20amp breaker on the generator, while other larger generators will have TWO 30amp breakers, and so forth.
