Very hot power cord with A/C on??
First time use on new trailer. When leaving RV park went to unplug power cord. Connector at RV site box was VERY hot to touch. Trailer is 30amp, as is power cord. Was running A/C but I've never exp...

If the wire is allowed to coil, it becomes an air cored inductor. Inductors tend to delay current changes; create local electromagnetic field, which can induce currents into nearby metals, electronic equipment etc.
But the property which can cause it to be potentially dangerous is the wire resistance and heat built up due to to many layers of close contact wire.
A standard 2.5 mm extension cord has a voltage drop of approximately 20mV/A.m.
So if we had a cord that was 50 meters long and 5 amps was being drawn through the cord, then there will be a 5 volts drop along the cord. This then equates to 25 watts of heat being generated along the cord. If the cord is still wound this heat will then build up and damage the cord.
