Electrical rough-in and device mounting at a rooftop exhaust fan curb assembly with an integrated wind screen. Power is supplied via PVC jacketed metal-clad cable supported along the assembly and routed to a NEMA 3R exhaust fan disconnect and a four-inch square box with a receptacle. A light fixture type 'R' controlled by a NEMA 3R motion sensor is mounted to the exterior. Conduit penetrations through the fan base route over a drip pan that drains to the associated electrical room below.
