Junction Boxes
Classified-location junction boxes engineered to match your fixture ratings.
What to Look For in a Junction Box
A junction box protects electrical connections from environmental exposure and, in hazardous locations, must prevent any internal spark or heat source from igniting the surrounding atmosphere — the same principle behind Explosion Proof Lighting. Key factors include ingress protection (IP) rating and hazardous-location classification, box size relative to conduit and wiring requirements, and material or corrosion resistance appropriate to the installation environment.
Junction Boxes in Hazardous Locations
In classified hazardous locations, junction boxes aren't just wiring enclosures — they're safety-critical components. A junction box installed in a Class I Division 1 area, for example, must carry the same classification rating as the fixtures and equipment it connects, since an unrated box could become an ignition point even if every fixture on the circuit is properly rated.
Where Junction Boxes Are Used
- Hazardous-location electrical installations — connecting classified fixtures and equipment safely
- Industrial facilities requiring classified junction points — anywhere wiring connections occur within a hazardous zone
- Outdoor and corrosive-environment wiring runs — protecting connections from moisture, dust, and corrosion
Choosing the Right Junction Box
Match the junction box's hazardous-location rating to the classification of the installation area — not just the fixtures it connects to. Confirm size requirements based on the number and gauge of conductors passing through, and verify material and IP rating for the site's environmental conditions.
