I think it would be nicer on the wall (and more secure from bumping from our gardening activities etc) if the condenser disconnect is mounted somewhat flush with my exterior stucco, rather than having the box stick out using the screws in the back.
It's going to be a Square D 60A disconnect. This disconnect has two knockouts in the bottom and two in the back.
But if I have it installed flush, then how should the conduit enter the wall, since the bottom knockouts would be inside the wall? For example, would it be just a section of metal conduit sticking out of the wall that a plastic condenser conduit can screw on to?
