That is a 12 volt breaker. NO 120 appliance will cause the overload to trip. Also a short in the DC supply to that breaker will trip it. I do NOT like manual reset breakers. I would replace with a auto reset breaker of the same amp. Transient things in RV's cause fuses and these type breakers to trip. With an Auto reset, once the overload or short goes away it resets. Both Auto and Manual reset breakers can wear out over time if they continually trip. Doug
