“On July 11, 2007, Norm Wild of National Property Inspections inspected our house at the buyers request. While much of his report is fair and accurate, his report had a few glaring errors that were so blatant I decided to write a response to bring attention to the problems…”
If the supporting structure is RIGID enough I would simply install a cover with a KO and run a peice of MC or sealtite down ( I say that because I would like to see the insulated EGC inside it…since I am talking surface extention ) and then mount a box to the support rack…then plug the unit it at that point.
