Plugging 30A 5th wheel into 50A service

Well I for one are confused, we are talking about an RV plugged into a distribution panel, but you quote house wiring, that is not what I am talking about, to be specific, I am talking about the wiring after the circuit breakers in the distribution panel. I have seen voltage on the 30 amp side as low as 90 volts, with hot to touch 30 amp plugs. At the same time, plugged into a 50 amp plug the volts were 109. My current rig is a 50 amp service, on my previous class c it was 30 amps, I always plugged into a 50 amp plug where available with an adaptor, and never had a problem. You are quoting theoretical "what should be", when in fact not all parks are wired that way, they cut conners, talk about understanding the basics, alway check before plugging your RV in to ensure that the recepticle is wired correctly! My autoformer will tell me before I plug in!
We all should take a deep breath and relax, again the original question was "can I plug a 30 amp Rv into a 50 amp outlet"? Your drawings and descriptions of all sorts of wiring diagrams do nothing to answer that question! A statement was made about the advantage of using a 50 amp plug with adaptor rather than using a 30 amp plug directly, if you disagree with that then fine, disagree and we will agree to disagree!

If everything is working correctly, that is outlet, pigtails to breaker, breakers and box buss bars you will not see any difference, except with the possibility that the leg the 30 amp outlet is on is overloaded and when you switch to the 50 amp outlet and adapter and you ended up on the other leg which was not overloaded.

It is just how electricity works. The theory of electrical flow is how it actually occurs in the wild!

If you experience a hot plug of cord, then there is a problem with the plug or outlet it is plugged into, or the amount of current being drawn.
