You may have moisture between Hot and Ground providing a capacitive coupling as opposed to a resistive "short" issue. A short would trip immediately as opposed to being a delay.
Possible, even likely.
The basement outlet, which is on the affected circuit, has been known to cause gfci tripping if that area got moist. I did pull it out and open it up, it all looks OK.
I did pump and dump today, but nothing over there got wet.
Question becomes, how to test it?
Or how to isolate it?
I have a single GFCI in the hallway. It has 2 romex cables connected to the load side. One of them is causing the problem, and I know which one it is.
But that line feeds a bunch of stuff, in 2 different slideouts, inside the coach, and in the basement.
