Learn what the NEC requires for junction boxes, from box fill calculations and grounding to outdoor use and fire-rated wall installations. The National Electrical Code (NEC), published as NFPA 70, sets minimum safety standards for electrical junction boxes in residential and. A conduit body is a removable-cover section of a conduit system that provides access at junctions or termination points. Outdoor electrical boxes must be installed at least 6 1/2 inches above grade, and in garages, 18 inches or more above the floor. Code requires these enclosures to house wire splices and terminations, mitigating the risk of short circuits and electrical fires.
