Amps For Dummies!!! (Like Me)

You can overheat the pedestal . Plug into 30 amp and run it close or at max power for the 30, then plug in a 1500 watt heater in the 20 amp plug in the same pedestal. None of the breakers will trip but you can overheat the pedestal and could cause a fire. If a 30 amp only pedestal (not 50 amp) 30 amp is the max load for the entire pedestal the 30 amp plug and the 20 amp. I encountered this last year when I was on a 30 amp just getting set for winter. The pedestal got very hot and could smell wiring. Breakers would not trip because each one was not over the limit for their load, but together it was overloaded. From my encounter with this. on a 30 amp pedestal, I would run a 1500 watt electric from inside the camper( 30 amp ) and no more that a 750 watt on the extension cord to 20 amp outlets.
