Park pedestal wiring
Just wondering if anyone knows the typical wiring for a park pedestal. My question is...Is the 30 amp outlet run off the same wiring as the 50 amp just with a smaller breaker and single hot? If I us...

Frequently (but doubtless not universally), the entire pedestal is limited to 50A maximum from any combination of the receptacles. The 30A and 20A breakers are fed from single legs of the 50A feed, with the 50A breaker being a main breaker for the pedestal as a whole.
Since so-called "50 amp RV service" is in fact 100 amp service because it's 50 amp across each of two legs any pedestal wired in this manner would offer a minimum 100 amp service, not 50.
The 50A RV service is 50A 120/240V split phase service. It is not a 100A service in any sense, although it does supply the same power as a 100A 120V single phase service would supply (12 kW in both cases). You cannot power a device requiring 100A (such as, say, a 12 kW 120V light bulb, if you somehow happened to have one) directly from the 50A RV receptacle. You could power a 12 kW 240V light bulb, of course, if you had one, at least until your neighbors complained and the campground management demanded you turn it off.
It's the same situation when comparing a 12V DC system with a 24V DC system. A 5A 24V circuit can supply the same power as a 10A 12V circuit, but that does not make it a 10A circuit in any sense. Adding a grounded center tap doesn't change this.
