Plastic distribution boxes in Senegal are typically made from flame-resistant or UV-resistant engineered plastics, with IP66 protection, compact designs, and compliance with national and international electrical standards.

Material and Construction

Plastic distribution boxes are generally constructed from ABS or heavy-duty UV-resistant engineered plastics, ensuring durability, impact resistance, and long-term resilience against harsh environmental conditions such as sun exposure and oxidation . Some models, like the SHPN series, feature ABS shells with PC doors, providing high dielectric strength and insulation voltage of ≥3.75kV and 1000V AC . Flame-resistant ABS is commonly used in modular series such as MB-ABC, MB-AF, and MB-AS, offering impulse-proof and excellent insulation properties .

Dimensions and Series

Distribution boxes come in various sizes to accommodate different installation needs:

• MB-ABC Series:
  • MB-ABC500: 200 × 174 × 95 mm
  • MB-ABC700: 255 × 172 × 95 mm
  • MB-ABC900: 328 × 172 × 95 mm These boxes support modular combination equipment for AC 50Hz, rated voltage 220V/380V .
• HA, HK, LGD Series: Dimensions range from 100–415 mm in length, 105–323 mm in width, and 75–140 mm in height .
• SHPN Series: Compact, wall-mounted design optimized for space-limited areas, suitable for indoor and outdoor installations .

Protection and Standards

• Ingress Protection: IP66, ensuring dustproof and waterproof performance .
• Mechanical Resistance: IK09, providing impact resistance .
• Compliance: Conforms to standards such as BS EN60439-3, JB/T7121-93, and national electrical installation requirements .
• Safety Features: Double insulation, flame-proof materials, and proper earthing systems for operator safety .

Installation Guidelines

• Fixed boxes should be installed 1.3–1.5 m above ground, while mobile boxes should be 0.6–1.5 m above ground .
• Maintain a maximum distance of 30 m between distribution and switch boxes, and 3 m between switch boxes and fixed equipment .
• Each electrical device should have a dedicated switch and residual current device (RCD) .
• Reserved openings for incoming and outgoing wires must be sealed to Class 3 standards after assembly .

Applications

These plastic distribution boxes are widely used in residential, commercial, industrial, and public utility settings, including high-rise buildings, hospitals, airports, and outdoor distribution networks . Their design ensures easy installation, maintenance, and aesthetic integration into surroundings. Overall, Senegal's plastic distribution boxes combine robust materials, standardized dimensions, high protection ratings, and compliance with safety regulations, making them suitable for a variety of electrical distribution applications.
