In the attached drawing I'm showing a mounting pedestal for a main lug from which to run a feeder to the house. To the left of the main lug is a 200 amp disconnect which is mounted on the utility pole. I'm not showing the meter but it is before the disconnect. About 18" of the pedestal is in the ground. I'm planning to run conduit and 2/0 copper from the disconnect to the main lug as shown, which is above ground. Does this look ok? I need a ground, i.e., four wires from disconnect to main lug, correct, and I do not bond neutral to ground at the main lug, correct?
