30A breaker on 50A receptacle?
I'm thinking of putting a '50A' receptacle on the side of my house where my RV is stored (only the receptacle outside in a box). The RV is 50A but I'd never need that much power in that location. ...

THe basic rule is the Circuit breaker should be no larger than whatever it protects (It protects the wires and outlet. what you plug in is not protected by the breaker)
SO if the wire is rated 50 amp, and the outlet is rated 50 amp, any circuit breaker smaller than 51 Amp is just fine (51 amp is too big).
IN fact.. I sometimes recommend that.. If you have a 30 amp RV and are having the thing installed professionally (The outlet) INstall a 50 amp Outlet, with 50 amp Wire (Six or heavier ga) and a pair of 30 amp breakers. then use a dogbone to 30.. That way upgrading to 50 amps (later if you choose) involves ONLY replacing the breakers, not new wire or outlets. Way cheaper
ALso,,,, on my 50 amp RV the Generatgor breakers are 30 amp so you should have FULL POWER or darn near full on 30 amps if you are well balanced.
