My rv plug got hot and melted at campground. I must not have twisted it tight enough. To save the trip i cut the end of the shore cord off and pulled the rv plug off and hard wired it in with wire nutts and covered with electrical tape. Two days later checking things for return trip I touched the bar that secures the ramp door and got a shock. Checked with meter to ground had 30 volts. Because I didn’t know about hot skin I left it . Got home and plug trailer in just like at campground hard wired and no voltage coming off the same places. I’m thinking the pedestal at campground was bad and questioning if that could caused the plug to melt.
The plug melting and the hot-skin shock were most likely unrelated. The hot-skin voltage probably was the result of a failed ground connection in the pedestal outlet. And you most likely had normal internal leakage currents in your RV electrical system of a few milliamperes.
But your melted twist-lock plug was probably due to a lack of contact maintenance (contact cleaner) and/or loose terminating screws in the plug itself.
I’ve studied these problems at some length and those are the most likely failure mechanisms.
