Most of the time you are better off using the 50 amp breaker if you have the adapter since the 50 amp sockets on the power pedestals are usually in better condition than the 30 amp sockets. They are used less. I'm speaking as a camp host.

Have a great day.

NOT TRUE. Are you stating that if your continous amp draw exceeds 24/25 amps the main 30 amp breaker or the individual breakers will trip? EXPLAIN your reasoning and don't attempt to use the NEC code which does not take into account RV type systems. Doug

I carry a 50 to 30 amp adapter, and on every trip have found at least one site that only had 50 amp receptacles. Usually in commercial RV parks that cater to permanent residents.

I've also sometimes used it when the 30 amp receptacle in a campground is in bad shape or when the 30 amp receptacle is providing low voltage. The heavier wiring for the 50 amp sometimes provides higher voltage in campgrounds with overloaded systems.

I do like DickB and always use the 50 to 30 for my 30 amp service

I have yet to see a spot that dosen't have both hook ups. Most power polls have a 50, 30 and a 20 amp hook up if they list 50 amp service. I do carry the adaptor just incase. There only like 20 bucks on amazon.

Circuit breakers are not limited to 80% of their rating. They will operate at 100% of their rating continuously without tripping. Only after they exceed the rating printed on the breaker will they trip.

Circuit breakers for any given circuit are supposed to be sized to operate no more than 80% of the rating. But, again, that does not mean they will trip at 80%.

It's not the worst idea for all 30 amp users to carry a 50 to 30 amp dog bone. Sometimes the 30 amp connection on the post is in really bad shape from people unplugging with the power on and the 50 amp connection is still good.
Are 50 amp users smarter about disconnecting or are there just fewer of them?

You can use the adapter.
