Well, absolutely everything is turned off in the trailer. The home circuit is a gfi breaker, I just push the button to reset. I don't think it's the home breaker, I run my compressor, power washer etc off this circuit. The shore power cable does have some cracks in it next to the metal prongs. It could be the shore cable as suggested. I tried turning off the trailer main ac breaker, and no home breaker kicked off. But it did kick off the home breaker as soon as I turned on the trailer main breaker. Unless there's any other suggestions, it looks like a new cable to me. Thanks a bunch.
