Galvanized rigid steel conduits pass vertically through a roof assembly, fitted with threaded caps at their upper ends. Each penetration is sealed with a flashing and counterflashing cone secured by a stainless steel clamping ring, with lap sealant applied at joints and the roof deck interface. Below the roof assembly, electrical junction boxes including a six-inch by six-inch by four-inch box and a four-square box connect to electrical metallic tubing runs.
