can someone tell me what could have caused my plug to burn up? I have an rv with a 50 amp to 30 amp adapter plugged into a 30 amp plus outside. I just noticed the one side of the adapter on the 50 amp...
Save some trouble and money. Only replace what was damaged and don't buy a whole new cord.
The reason things are heat damaged is that they were not capable of carrying the load. Replace just those parts. But if you are not sure which was the bad part, replace both.
It is very easy to do this if you are running a 50 amp coach on a lesser service. You have to be very careful.
