I would definatlly put a disconnect right next to the door. What size conduit will 6 and 8 fit in? Looking at NM-B since it's cheaper than running single strands Fan has starter switches so will direct wire Probably needs 6 gauge? Probably 20-30 feet from panel. Will 8 gauge hold it with a 40 amp breaker? Should I put a disconnect in or just use breaker in panel.
