Just got back in , while out this week end we blew the 30amp breaker at the campground. The maintance man came by and replaced it. He said that we need to ge a 50 amp adpter and run out 30 amp off this. It does not make any sense to me any thoughts

Could be that thier 50 amp circuit is new wiring and is capable of sustaining a better amp load. Your 30 amp at full load may be pulling close to or slightly over 30 amps and is stressing out the wiring on the 30 amp circuit. With an adapter from their 50 amp plug in to your 30 amp cord you might be able to pull close to or at a full 30 amps without topping out their system. Just a thought.

What you haveare two 30Ampbreakers in series protecting yourtrailer. One 30Amp on the post and the 30Amp breaker in your trailer. My guess is that the 30Amp breaker had to be changed because it had tripped enough times that if you were pulling anything near 30 amps, it wasn't capable of maintaining a 30 amp load from your trailer. You must be cognisant of the load that you are putting on the post supply. The comment by the electrician is bogus because if you did what he suggested, then it would be your 30Amp breaker tripping and not the one on the post.

Here are typical loads of your appliances in the trailer. A/C -->15 to 18 Amps, Water heater ---> 10 to 12 Amps, Fridge ---> about 2 Amps, Converter---> 5 to 8 Amps. Let suppose that your loads are at the minumum of my guestimates. You've got the A/C going, the water heater is on electric, the fridge is on electric and ofcourse the converter is going all the time. If all the appliances happen to be on at the same time, there's going to be a 30Amp breaker trip somewhere, because your load is 15 + 10 + 2 + 5 = 32 Amps. If one of the appliances is not running and you fire up say the microwave and the DW puts on the electric kettle, then you're going to have a 30Amp breaker trip. When you only have 30 amps of electricity available, you need to substitute where possible (run on gas) and time share the service. eg. If one heavy load is going, don't fire up another heavy load, unless you want to sit in the dark.
