    Product Overview

    We supply an explosion proof junction box designed for hazardous location lighting and marine environment lighting. This enclosure is built for use in Class I, Division 1 and Division 2, as well as Class II and III hazardous areas. It is suitable for surface mounting and supports 3/4" NPT conduit entries. Typical installations include chemical processing facilities, oil and gas sites, and offshore platforms where certified enclosures are required for safe electrical connections.

    The housing is corrosion resistant and IP66 rated for wet locations and marine environments. This junction box is commonly used to support and interconnect explosion proof lighting fixtures in areas with flammable gases, vapors, or dusts. The compact form factor allows for installation in confined or exposed locations.

    Core Performance and Output

    This junction box is engineered to maintain the integrity of hazardous location lighting systems. It is certified for use in Class I, Division 1, Groups C and D, and Class I, Division 2, Groups A, B, C, D. It also meets Class II and III requirements for dust and fiber environments. The enclosure supports 100-200W lighting circuits and is rated for 12000-26000 lumen fixtures at 100-277V operation.

    UL 844, UL 1598, UL 1598A, and ABS certifications confirm suitability for hazardous, wet, and marine locations. The IP66 rating ensures protection against water ingress and dust. The box is not intended for use with lighting loads exceeding 200W or for applications requiring larger conduit entries.

    Adjustability and Control Options

    This junction box provides fixed conduit entry points with 3/4" NPT threading. There are no adjustable or modular features. The enclosure is designed for standard surface mounting and does not include integrated control devices or field-adjustable options.

    Control wiring and dimming circuits can be routed through the box as required by the lighting system design. All connections must comply with hazardous location wiring practices.

    Longevity and Reliability

    The enclosure is constructed for long-term use in corrosive and hazardous environments. The IP66 ingress protection and marine-grade finish prevent water and dust intrusion. The housing resists corrosion from salt spray and chemical exposure.

    All gaskets and seals are designed to maintain hazardous location ratings over the service life of the installation. The product includes a 5-year warranty covering material and manufacturing defects.

    Build Quality and Physical Characteristics

    The junction box measures 5.6 x 5.6 x 4.2 inches. The housing is fabricated from corrosion-resistant materials suitable for marine and chemical environments. All conduit entries are 3/4" NPT for compatibility with standard hazardous location fittings.

    The enclosure is UL 844, UL 1598, UL 1598A, and ABS certified. The compact size allows for installation in tight spaces or on exposed structures. The box is designed for surface mounting and includes all required gasketing for hazardous and wet locations.

    Where This Product Fits Best

    This explosion proof junction box is intended for hazardous and marine environments where certified enclosures are required for lighting system connections. It is commonly used in:

    • hazardous location lighting
    • explosion proof lighting
    • paint booth lighting
    • chemical processing facility lighting
    • oil and gas facility lighting
    • refinery lighting
    • marine environment lighting
    • offshore rig lighting

    The enclosure is suitable for wet, corrosive, and high-risk areas where flammable gases, vapors, or dusts are present. The IP66 and marine ratings support use in outdoor, coastal, and offshore installations.

    Installation and Long-Term Use

    Surface mounting is standard. The box is compatible with 3/4" NPT conduit and hazardous location fittings. All wiring must follow hazardous location codes and best practices. The compact size allows for installation in confined or exposed locations.

    Routine inspection of gaskets and conduit seals is recommended to maintain hazardous location integrity. The enclosure is designed for minimal maintenance in corrosive and marine environments. All hardware is corrosion resistant for long-term reliability.

    How This Fixture Is Commonly Used

    This junction box is typically installed as part of explosion proof lighting systems in hazardous and marine environments. Mounting height is determined by the location of lighting fixtures and conduit runs, with most installations at ceiling or wall level.

    Spacing and placement depend on the layout of lighting circuits and the number of fixtures served. Using a single box for multiple fixture connections can reduce installation time but may require careful planning to avoid overcrowding. The compact form factor supports flexible placement in both new and retrofit projects.
