Explosion-Proof Junction Boxes and Lighting Controls
Explosion-proof junction boxes provide a protected location for electrical connections in hazardous classified areas. Our selection includes standard junction boxes and models equipped with a photocell or motion sensor for controlling compatible lighting in Class 1 Div 1 and Class 1 Div 2 locations.
The junction box and control must match the classification of the exact installation area. Before ordering, confirm the required Class, Division, Group, voltage, ambient temperature range, conduit arrangement, and environmental ratings. A Class 1 Div 2 product should not be installed where Class 1 Div 1 equipment is required.
Available Junction Box Options
- Standard junction boxes: Provide an enclosure for wiring connections, splices, and terminations in compatible hazardous locations.
- Junction boxes with photocells: Automatically control compatible lighting based on available daylight. These are commonly used for outdoor process areas, loading locations, tank farms, and other classified spaces where lights should operate from dusk to dawn.
- Junction boxes with motion sensors: Control compatible fixtures when activity is detected. They may be useful in intermittently occupied storage, service, loading, or process areas where automatic operation can reduce unnecessary lighting hours.
A photocell responds to ambient light, while a motion sensor responds to activity within its detection area. Confirm the control method, switching capacity, detection pattern, mounting position, and compatibility with the connected LED fixtures before ordering.
What to Confirm Before Ordering
- Hazardous-location rating: Verify whether the installation requires Class 1 Div 1 or Class 1 Div 2 equipment and confirm the applicable material group.
- Voltage and electrical load: Match the junction box and control to the circuit voltage and total connected lighting load.
- Fixture compatibility: Confirm the photocell or motion sensor can properly switch the selected LED drivers without exceeding its rated capacity.
- Conduit entries: Review entry size, quantity, orientation, sealing requirements, and available space for conductors and terminations.
- Sensor placement: Position photocells away from light produced by the controlled fixtures. Confirm that motion sensors have an unobstructed detection area and suitable mounting height.
- Environmental exposure: Verify suitability for moisture, dust, corrosion, chemicals, temperature, vibration, and outdoor conditions.
The complete electrical system - including conduit, fittings, seals, cable glands where permitted, grounding, bonding, and connected fixtures - must also be suitable for the classified location. The junction box does not make standard wiring components or fixtures acceptable for hazardous use.
Certifications, Installation, and Warranty
Confirm the exact product markings and certifications for the required Class, Division, Group, voltage, and environmental conditions. Ratings and control features vary by model and should be verified on the product specification before ordering.
Explosion-proof junction boxes and controls should be installed by a qualified electrician experienced with hazardous classified locations. Installation must follow the product listing, manufacturer instructions, applicable electrical codes, area-classification documents, and authority-having-jurisdiction requirements.
Warranty coverage varies by product and application. Review the selected model for its certification, switching capacity, environmental rating, operating limits, and warranty terms.
