50A Idea

In our trailer, the amp load from the converter (after at least 5 minutes of charge), the TV, and the fridge on electricity are insignificant enough that we can ignore them and not trip any 30 amp breaker. The big amp hogs are AC, microwave, electric element in the hot water heater, and hair dryer. By limiting to 2 of those at a time, we never trip a 30 amp breaker. Because the switch for the water heater is outside and inconvenient, it stays off and runs on propane. In out experience, there is no need to switch the fridge to propane—ours draws 2.8 amps only when it is cooling. When the OP tripped the pedestal breaker it was likely because those pedestal 30 amp breakers have been tripped many times while the 30 amp main breaker in the trailer is brand new and may never have been tripped. It is usually thought that repeated tripping makes a breaker weaker and more prone to trip. On a quick read I don’t think that anyone mentioned that adapting the cord of a 30 amp trailer to a 50 amp outlet in the pedestal is setting up a 30 amp cord with only 50 amps of protection—you’ll get that cord pretty sticky hot before the 50 amp breaker trips if something goes wrong and the 30 amp breaker in the trailer does not trip. But, yes I’ve used a 50 to 30 converter also.
