Diagonally or rectangularly installed, the description implies the service disconnect is in the panelboard and the diagonal run of 50 feet is inside the building. It sounds like the service conductors are accessible inside an attic. This leads me to think the requirements of NEC 230.7(1) are not met since the service disconnect is not located at the point nearest the point of entrance.
Does the AHJ have an allowable length from the point-of-entrance to the location of the DS?
