This question would get more play in our Tech Issues forum, as this generator isn't just in Class C's. Might play still better on SmokStak.com which has a Generac section.
In addition to breaker(s) on your generator, there will also be breaker(s) on you coach's Load Center. That's where 12VDC Fuses, 120VAC Breakers, possibly an Inverter, and most likely your Converter/Charger are.
Also, how does your coach shift from shore tie pedestal to generator power? Ours and many others uses an Automatic Transfer Switch. Some, the generator powers an outlet, like the one a shore tie pedestal has, and you unplug from the Pedestal and into that on board Outlet.
