Dogbone Melted

Have any of you guys seen anything like this. My 2010 Jayco has 50 amp service and is usually hooked up to power to keep the batteries charged with a 50-30 amp and a 30-20 amp dog bone adapters. In this particular instance there has been no power draw on the rig except the converter and maybe a light or two on occasion if we enter the camper at night or need to run a slide out.

I suspect maybe moisture got inside the connection and caused a short which over heated the connection. The breaker inside my work shop that powers this circuit was tripped also.It's been raining a lot lately and this connection was exposed to the rain.

    Is it a Cameco female connector? I find those unreliable and subject to burn on low loads.

    Most recently, a home owner where I was staying switched me over (without my knowledge) to a #14 50 foot extension cord. The female on the cord was loosey goosey and sure enough the 15 amp male end burned.

    I use anti corrosion on my plugs such as deoxit.

    No, I've never seen anything that bad. Seems to me if it was a short the breaker would have tripped. I've had lots of those exposed to rain without anything like that. That usually happens from too much load and a poor connection.

    Do you have any idea over what period of time this happened?
