Isn't the typical 50/30/20 amp pedestal intended to service one site and not to do double or triple duty serving more than one site?
Yes absolutely not.
It would be interesting to see what the rating is on the breaker back at the distribution panel.
I'm betting on twin 50's.
Pedestals nowadays are typically loop fed from one to the next and the feeder between them is sized according to demand factors in the NEC. In the olden days, they used weatherproof panelboards distributed around a CG/RV park with a 30 amp sub-feeder cable to individual pedestals in a radial fashion. The old way is not as efficient as loop feeding multiple pedestals on the same feeder plus can result in excessive voltage drop. You can have say a 300 amp breaker feeding a number of loop fed pedestals. I can't recall the max. number of pedestals on a loop-fed run, but I think it's something like 8 at 50 amps. Pedestals are available with min. 70 amp up to 200 amp mains ratings. Pedestals can be configured in a number of different combos of 30 & 50 amp recepts. All pedestals are required to have a 20 amp recept.
