Specifications and Models of Small Outdoor Distribution Boxes

Small outdoor distribution boxes are weatherproof enclosures designed for safe power distribution, available in various models with IP/NEMA ratings, modular channels, and capacities suited for residential, commercial, and industrial applications.

Key Specifications

1. Environmental Protection: Outdoor distribution boxes must withstand moisture, dust, UV exposure, and impact. Common ratings include IP65 (dust-tight and water-resistant) and NEMA 3R or 4 for rain-tight enclosures, ensuring compliance with NEC Article 312 for wet locations . 2. Material Construction: Boxes are typically made from ABS or polycarbonate shells with flame-retardant, halogen-free, and silicon-free materials. Some models are UV-resistant and impact-resistant (IK09), suitable for harsh outdoor conditions . 3. Electrical Ratings: Small outdoor boxes often support rated voltages up to 400V and currents around 75A, with modular designs offering 4 to 36 channels for flexible circuit distribution . Bus bars are usually copper or aluminum, and overcurrent protection devices like circuit breakers or fuses are included . 4. Temperature Range: Typical operating temperatures range from -5°C to +40°C, with some models capable of handling higher wire temperatures up to 650°C . 5. Installation Features: Many boxes allow customizable gland holes for cable entry while maintaining IP integrity. They can be wall-mounted or pole-mounted, depending on the application, and often include lockable covers for security .
