I have a travel trailer and it keeps tripping the main 30 amp breaker,so I was wondering if I could change out the 30 amp converter to a 40 or 50 amp converter without changing all of the inside wiring? I do have a small fridge,drop in electric stove ,small microwave,electric hot water heater,water pump and over head lights.The main breaker is 30 amp with all the rest of the breakers (4 more ),20 amps.So would changing the converter work or just upgrading the breakers to higher amps? Any and help would be great. Thanks !
