I agree. If you are going to run 4 wires, install the outlet and breaker that takes all 4 wires. Done once and finished.
That is what I did. I have a 30 amp RV. For now. When I ran my power, I pulled three 6g wires (black, red, white) and one 10g wire (green), put in a 50 amp breaker, and a box with 50amp/30amp/20ampGFCI outlets and breakers. I will never have to touch that wiring again, no matter what I may buy in the future. It did not cost THAT much more to do than a straight 30 amp setup would have been.
(While doing this, I also ran a second conduit and installed a separate box with telephone line and satellite/cable coax. Like I said, done once and finished.)
I am curious, you say "I pulled three 6g wires (black, red, white) and one 10g wire (green), put in a 50 amp breaker, and a box with 50amp/30amp/20ampGFCI outlets and breakers" is that code compliant? Potentially you could have 100A drawing on that one 50A breaker in the panel if you had all three receptacles being used at the same time. I know that is unlikely, but is it code?
Obviously if you try to have 100A flowing through the 50A breaker for more than brief instant, it will trip. That's what it is there for—to prevent overloading the circuit that can only safely (at least in the "what the code deems as safe" sense) carry 50A. (Household circuit breakers are designed to allow a momentary overcurrent without tripping to account for startup surges.)
Typically these camper multiple outlet panels are wired with the 30A on one leg and the 20A on the other leg and, of course, the 50a on both legs, so you wouldn't get 100A on one of the 50A breakers, just 70A...but that's not really pertinent to your question.
This is a code compliant installation, to the best of my knowledge, assuming the rest of the work is also up to code standards.
Thanks for answering my question. "I know that is unlikely, but is it code?"
Completely understand the potential for overload "YOU" answered my question.
