I had  an issue with my plug last summer.  I didn't pay close enough attention when reeling in the cord before leaving the house for our summer trip and it hit the end harder than it should have.  About a week into the trip my transfer switch quit working, eventually I figured out that one of the leads had pulled loose so I was only getting one leg of the supply current.  The transfer switch won't trip unless it has both legs hot.
