Explosion-proof distribution boxes should be installed in accessible, low-risk areas away from heat, collisions, moisture, and flammable or corrosive substances.

Key Location Considerations

Hazardous Area Classification: Explosion-proof distribution boxes are designed for environments with flammable gases, vapors, or dust, typically classified as Zone 1 or Zone 2. They are suitable for Type IIA, IIB, and IIC hazardous locations and temperature groups T1–T4 . Avoid High-Risk Zones: Do not install near areas prone to flooding, flash floods, unstable slopes, or geological hazards. Avoid farmland, vehicle traffic paths, dense tree clusters, residential yards, and sensitive sites such as historical monuments or national memorials . Proximity to Flammable Materials: Keep the box away from locations with high concentrations of flammable gases, explosives, corrosive chemicals, or severe contamination to prevent accidents . Collision and Heat Protection: Install the box in a location with minimal risk of mechanical impact and away from heat sources. If outdoors, a rain cover should be used to prevent water ingress and rust . Accessibility and Maintenance: Choose locations that allow easy access for inspection, maintenance, and future expansion. The installation path for the main circuit should be as short and direct as possible to reduce costs and simplify layout . Environmental Durability: Prefer areas that are corrosion-resistant and moisture-resistant to extend the service life of the distribution box. Ensure the installation inclination does not exceed 5 degrees . Material and Standards Compliance: Use stainless steel boxes (Baosteel 304 or higher) with a minimum thickness of 4 mm. All components must comply with national standards (e.g., GB7251) and maintain proper electrical clearance and creepage distances .

Summary

When installing an explosion-proof distribution box, prioritize safety, accessibility, and environmental protection. Avoid hazardous, flood-prone, or collision-prone areas, maintain proper grounding, and ensure compliance with relevant standards. Proper placement not only ensures operational safety but also extends the equipment's service life and reliability .
