Bj, I know that I'm going to regret asking, but why not do as Doug suggests and as I do?
"(I just kill the 2 20 amp breakers in my shop when I leave)"
Years ago I had a garden reticulation system where water from the bore was insufficient so I used to pump it into a 1000gal. tank and reticulate from there with a separate pump. The point of this story is that one night the tank sprung a leak and the pump kept going all night because I had fitted an air pressure level switch to the tank. I therefore fitted a solar time switch to make sure it didn't happen again.
