I plugged into 2 pedestals to verify if one had a problem and that is how I determined that it was not the receptacle but the plug,I was actually pulling between 32-34 amps on the digital readout,on a 90 degree day it will take all 4 cruise air units running to cool the interior to 68-70,each unit will draw 13-14 amps and with the chargers the total is 32-34 per leg.I have always tried to stay in the less than 80% range which is 40 amps or less and that will assure that the breaker will not trip unless it is weak or there are loose wires in the pedestal.
