this is what I was wondering, can you can plug into a 50 amp supply with a 30amp R/V with a proper adapter? and if so can you draw 50 amp. I guess what i'm try to get to is the cord from the R/V to the power supply on a 30amp R/V is not rated for 50amps. mine looks like # 10.

If you plug your 30 amp capable RV into a 50 amp source with the proper adapter, you'll only be able to draw a total of 30 amps before the RV's main breaker trips. Only a short in the RV cord itself could draw a heavier load, but the 10GA wires in the cord are capable of tripping a 50 amp breaker if shorted. A partial short could conceivably cause enough heat to melt the insulation before the breaker trips, but that would be an extremely unusual event.
