A 50-Amp service with up to 50-Amps per leg can provide almost unlimited power by comparison.


Assuming campground doesn't limit it, if someone wanted to plug in various devices at once that would exceed the typical 20-Amp circuit, why not use the 50-Amp breaker with adaptor as previously discussed at beginning of thread? With correct combination of adaptors it should be possible to get a lot more than 30-Amps for motorhome plus over 20-Amps for outdoor use. I've seen some adaptors that even split into two separate plugs -- could use one for MH and the other for outdoor kitchen. As to extension cord ratings, another option is a standard 30-Amp RV cable. Am I overlooking something?

The OP is going to plug a 30 amp coach into the campgrounds 50 amp pedestal and wants to use the pedestal's 20 amp circuit to power small appliances for use with the outdoor kitchen. The current concerns are the rating of the extension cords that should be used and how to use the appliances without constantly tripping the pedestal breaker. With my prior 30 amp class C I did this on a couple of occasions at campgrounds providing 50 amp service only with an included 20 amp outlet on the pedestal. With the current 50 amp coach, I still use an extension cord off the 20 amp service at the pedestal for running the toaster etc... in the morning and the canopy LED lights at night.
