The only issue in using the 50A is that the wiring from the plug all the way to the trailers 30A breaker is not properly protected.
But, if my Progressive Industries PT30C is connected at the post, would that not protect the wiring?
No.
While it is very unlikely that a short would develop and cause a load of under 50 amps, it is possible. If it were to happen, the 50A breaker would not trip and the heat from the short, or the overloaded wiring, could cause a fire. That said, I would use the 50A dogbone, but only when the 30A is questionable.
