in the past 14 months i have had to replace the 30A plug that plugs into the rv parks box at least 3 times because 1 of the prongs overheats and melts my plug. need ideas on what might be the cause
Not suggesting user error, but are you hot plugging or removing a lot (put plug in or out with pedestal power switch on and heavy loads on); or is your plug shape preventing you from fully inserting it in the socket? Somehow you are getting more resistance (heat) at your contact.
