    Usually 30 amp, sometimes 20 amp, some have a re-setable fuse

    As said above, 30 amp fuse or 30 amp circuit breaker. Either are available from any auto parts store. And with a fuse, bigger is not better

    I use a 20 amp and haven't had a problem yet, but everything connected to it combined doesn't draw 20 amps. The 3 way fridge is wired directly to the battery with it's own 15 amp inline fuse, it draws between 9 and 10 amps.

    max fuse size usually depends on wire size.
