50 amp to 30 amp adapter
I have a 30 amp trailer. If I found myself in a campground with only 50 amp service is it safe to use a 50 amp to 30 amp adapter? In other words, will using 50 amp service damage any electrical compon...

Sound Guy - good links.
Most RVers don't care about the electrical specifications and know that 50A can supply more power than they can use and they don't care about the details. Labeling doesn't really matter as there is one and only one 50A RV circuit.
But in the electrical world with many possible 50A circuits it is a 120/240V 50A 3 pole 4 wire 60HZ single phase circuit. Incorrect labels line 2 phase and 100A circuit are in wide spread use in the RV world and I'm sure will remain that way.
In the RV world it's reasonable to think of it as having 2x 120V 50A capability.
In the electrical world it's known that the 50A label applies to the higher voltage. It's also a fact that the circuit can supply any combination of both 120V and 240V as long as neither hot leg exceeds 50A. The design is also such that the center tapped neutral will carry the difference between the hots and hence never exceed 50A.
