Electrical Post from 2014 SAVED US
Not more than a month ago, I read a post from 2014 talking about a replacement male 50 amp plug that would fit through the marine style opening of a Liberty coach. Most importantly, I book marked it, along with other good posts and articles I have read on PC Forum.
Well, yesterday, the campground 50 amp pedestal breaker tripped and I found my shore cord male plug had become so hot that it cracked. I was fortunate to find an rv store nearby with the Intertek RP-501 plug as described in the 2014 post. A Harbor Freight was also nearby so I purchased a two tools I did not bring along – a cable cutter and a 6″ bench grinder.
Here is a link to this plug on Amazon. It is important to note that the Intertek RP-501 comes in a variety of packing and model numbers BUT the TRUE model number RP-501 is consistent and is stamped on the plug. When I called looking for it locally, the store clerk opened the package and found “RP-501”.
The bench grinder was necessary to file down the metal contacts as they are a bit too long to fit through the 3″ round door opening.
I wonder why the original cord got so hot that it split open and oozed a sticky grey liquid type substance. The plug was so HOT, I could not touch it for several minutes. Perhaps it was a faulty plug as the entire shore cord to which it was attached was installed just this past April.

One of the hardest things to keep up with, and which can be a contributing factor not only in our coaches but also with the shore power pedestal is loose electrical connections.
I have no clue how we can stay up to date on connections except to say if I am bored and have nothing to do I should spend some time cleaning and tightening connections on my bus.
Over the years I have had several malfuncts (a highly technical term) that I could attribute to loose or corroded connections.
