The plug on the end of my 50A power cable has separated from the cable. This is the end that connects to the power box. This cable is only two years old. It still works fine but the gap is about 3/16" and I can see the wires inside of the cable. I have never put any stress on this cable.It looks like the rubber outer casing of the cable was not properly attached to the plug. Has anyone else run across this problem?I can seal the gap with gorilla tape but wondering if it is possible to have it repaired. Any inputs appreciated. Guess this is another example of sub par Chinese manufacturing.John in Fl

You can stretch the sheathing- lay it out in the sun, start at the coach end, secure it and "massage" the sheathing (basically pulling it- use gloves). Then seal with Goop.It's easier to do than describe.

Unless that point is exposed to the weather or subject to friction, all you need to do is fill the gap.....or not worry about it at all. The inside wires still have more than sufficient insulation unless stressed for some reason.Now.....if you can see bare copper, that's a whole different matter and the plug needs to be re-done; replaced probably.

Mine has been that way for years. It is the outer insulating sheath shrinking but you are seeing the individual insulation underneath, it is still safe.

Try what Chris Bryant says. You can work back a good three or four inches if you start working the outer part of the cable at the other end... Then apply the goop or glue to seal it in place once you get it inside the plug assy... I've had to this to my large cables a couple of times over the years...

Not 50 amp, but 30, but the problem is still the same. OEM plugs with molded rubber covers don't stay attached for very long, clamp-on plugs might last a bit longer. The cable itself should last forever, plugs get replaced periodically, if you don't pull them off you'll eventually burn the blades.

Over 10 years I am on my third plug for the original cable, and I now carry its replacement in my parts kit, along with stuff like fuses, a spare cap for the water connection, and a spare plug for the water heater.

+1 on this. Used JB Weld to hold mine in once stretched back into place.
Been good at least five years now. (30a cord)

Thanks to everyone for the tips and suggestions. Think I will stretch the outer sheath, put a stainless steel hose clamp near the plug to hold it there and some JB Weld or goop to seal it. Think I will do that to the other end of the cable too.
