It seems unlikely to me that they are producing their cords to the rated specs. The cords should be able to handle 30 amps continuous withou overheating or burning up. THat does not seem to be the case in any of these instances.

I am not sure the exact series of events that causes the failure. It is possible that corrosion is building up on the terminals inside the plug. That in turn causes more heat. THe heat in turn causes more corrosion until it is a vicious cycle.

That is my rough guess at this time. However, it is getting hot enough that the enire receptables is melting down and failing. THe failures do not, in any instance, stop at the plug. They over heat to the point of causing the plastic structure of the receptacle to literrally burn up such that when you pull out the plug you will quite literally pull out the entire prongs of the receptable (often a hot wire... you should note).

Has this been others experiences too?

PS In 15 years of boating, I have never had this problem on previous cords - including when we were liveaboards in FL on CRUDDY power.
