Progressive EMS repair

This didn't just happen with one incident. I think it's been getting damaged over time. But don't recall any loose outlets. At home before we left for our summer travels, we did have sustained high amp use from running the basement A/C alot. Our 30amp breaker at the house tripped a few times. Well, later when we were on the road, our 30amp plug melted and the cord was hot all the way to and including the electric box in the storage bay. Problem was there were a couple loose screws that hold the 30amp cord in the electric box in the storage bay. Didn't have the EMS plugged in that time. But the loose screw problem must have been happening over time and I just didn't notice the heat that was causing until it was too late.

Anyway, I suppose this could have caused the EMS plug to get damaged over time.

I'll look into changing just the plug on the EMS.....or I'll decide to buy a new unit.

Thanks for all your comments. Much appreciated.
