Cameroonian home distribution boxes typically feature robust, insulated enclosures with dimensions ranging from 200–328 mm in length, 172–174 mm in width, and 95 mm in height, designed for safe residential electrical distribution.

Enclosure and Material

Home distribution boxes in Cameroon are generally made from glass fibre reinforced polyester or flame-resistant ABS plastic, providing excellent insulation, corrosion resistance, and mechanical strength (IK10 rating) for operator safety and durability against UV, heat, and chemicals . The enclosures often feature a double layer of insulation to enhance safety .

Dimensions

Typical dimensions for residential distribution boxes include:

• Length: 200–328 mm
• Width: 172–174 mm
• Height: 95 mm These dimensions correspond to common series such as MB-ABC500, MB-ABC700, and MB-ABC900, suitable for modular installation in homes and small buildings .

Electrical Specifications

• Fuse Type: 22 x 58 mm, rated up to 80 A for collective housing connections .
• Voltage Rating: AC 50 Hz, 220/380 V .
• Network Connection: Supports 35–240 mm² cable cross-sections with 2–4 network bypasses up to 35 mm² .
• Busbars: Aluminium busbars are used, with sizes varying according to transformer capacity (e.g., 72x50x8 mm for 63/100 KVA, 1120x50x15 mm for 160/315 KVA boxes), .

Installation Guidelines

• Mounting Height: Fixed boxes should be installed 1.3–1.5 m above ground, while mobile boxes can be 0.6–1.5 m .
• Spacing: Distance between distribution boxes should not exceed 30 m, and horizontal distance to fixed electrical equipment should be ≤3 m .
• Safety Compliance: Each box should follow the "one equipment, one switch, one RCD" rule to ensure safe operation .

Features

• Mechanical Protection: IK10 impact resistance .
• Ease of Installation: Knockouts and cable entry points for convenient wiring .
• Safety: Double insulation, flame-proof materials, and protective short-circuit sets .
• Applications: Suitable for residential homes, high-rise buildings, hospitals, commercial spaces, and collective housing . These specifications ensure that Cameroonian home distribution boxes provide safe, reliable, and standardized electrical distribution for residential and small-scale commercial applications.
