The circuit breakers are there just incase the main cable shorts to the body or chassis.

The size of the fuse or circuit breakers depends on the cable size used and to some degree what you plan on running from the rear battery.

If you have used 6B&S cable and are only running a fridge and some lights I would use 60amp circuit breakers.

You could easily go up to 80amp circuit breakers, the cable will handle this in normal operation.

The concern with going to high with the rating of the circuit breakers is if a partial short occurs it is possible that the current can slowly rise and the cable may overheat before the circuit break trips out.
