Racecarl, I have done what you said. One wire to each pole of a double pole breaker that go directly to an outlet in the shed which has the two outer and upper "slits" energized by the red and black wires, with the ground going to the center lower "slit." This should mean that it is wired right, shouldn't it? I also know the importance of getting an electrician to check it out. My neighbor is certified and he said that he'll take a look at it.
