electrical question
I have 50 amp service at my pole barn, where my rv will be stored. My rv is a 30 amp tt. Would I be better off using a 50 amp surge protector, then plugging in a 50 amp to 30 amp adapter; or, using ...

There is no danger at all in using the 30A cord that came with his RV to plug into 50A.
Of course I understand the situation, and also understand that 10 gauge wire is not rated for 50 amps. While a problem may never happen, I am not the one to promote the use of undersized components. After seeing poor installations of RV inlets and any manner of connections, I will let it to others to recommend this type of thing. If we lived in a perfect world, circuit breakers would not be needed.
Respectfully, your looking at this backwards from what is actually happening. There's nothing undersized when a 30A rig plugs into 50A. It's oversized. As you know, a 50A circuit will have everything bigger and will carry the load even better. As I indicated before, the 50A breaker plays no role in protecting the 30A circuit - that's not its job.
It's just like when you plug in an extension cord, lamp or other small item at home. The ext cord or lamp and its wiring are far smaller than the house wiring. The 15A breaker for that circuit is only there to protect the house wiring and not the lamp.
