Is it okay to plug 30 amp camper into 50 amp campground receptacle using an adapter? Is there any advantage doing so, if both 30 and 50 amp are available?

Yes there is an advantage to use the 50 amp outlet. It is less used and the contact blades will be much tighter than the overused 30.

There will be no up or down in voltage. Voltage drop has to do with amp draw and wire size and distance, it does not accrue at the plug.What you will have is a better tighter connection with the 50 because of less use. Always plug your 30 into a 50 if available.


Our statements were correct, just did not get into specifics as to why.

Thanks for the responses. My camper is 30 amp, and I can trip that outside breaker pretty easily.

Its not going to give you anymore power. If your tripping stuff now you need to use less stuff, lol.

could make adapters so that you could use either side of the 50 amps in case one side was overloaded.

With a good adapter, no problem, and the 50A will likely have less wear, with cleaner contacts.

As others have said, it is OK to do. I have found a couple of times I needed to use the 50 amp even though there was a 30. Once when the 30 amp was wired reverse polarity, and more than once when the 30 amp connector was damaged enough that the 50 provided a more reliable connection.

I plug into the 30. If it feels loose, I use an adapter and plug into the fifty. You are checking both first, correct?
