Any enclosure approved for a Class I Division 1 or 2 location that contains splices, terminals, devices or controls: outlet bodies, junction boxes, GUB instrument enclosures, bolted enclosures and push-button stations. The approval is the Class, Division and Group marking on the box; NEMA 7 describes the enclosure construction that achieves it.
Explosion-Proof Electrical Components
Browse junction boxes, EYS and ENY sealing fittings, NEMA 7 and 4X push-button stations, and UNF or UNY unions for classified electrical systems. CEC Section 18 treats the equipment, wiring method, threaded joints, bonding and seals as one installation. Match each component's approval, classification, group, temperature and environmental rating to the authenticated drawing and the manufacturer's instructions.

Zone 1 Sealing Requirements Canada: 5 Mistakes
Zone 1 sealing requirements Canada projects often fail on distance, factory-sealed assumptions, boundary seals, and migration seals. Here are the five mistakes to catch early.
NEMA 7 vs NEMA 4X vs Explosion-Proof: What the Ratings Mean
NEMA 7 describes an enclosure built to contain a Class I explosion; NEMA 4X describes water and corrosion resistance. Neither is a hazardous-location approval. Here is how the ratings, the markings and CEC Section 18 fit together.
