A Level 3 distribution box in Rwanda typically has dimensions around 600 mm (length) × 400 mm (width) × 250 mm (height), designed to accommodate multiple ways for medium-voltage and low-voltage connections.

Overview

Level 3 distribution boxes are part of Rwanda's electricity distribution network, used to manage and distribute power from medium-voltage lines to low-voltage feeders. They are standardized to ensure safety, reliability, and compatibility with the national grid infrastructure . These boxes are generally mounted on poles or concrete pads and are designed to house circuit breakers, fuses, and busbars.

Typical Dimensions

According to distribution box catalogues and industry specifications :

• Length: 600 mm
• Width: 400 mm
• Height: 250 mm These dimensions may vary slightly depending on the manufacturer or the number of ways (connection points) required. Level 3 boxes are usually designed to accommodate 12 to 24 ways, allowing for multiple outgoing circuits.

Material and Construction

• Material: Powder-coated steel or corrosion-resistant aluminum
• Protection: IP54 or higher for dust and water ingress
• Mounting: Pole-mounted or wall-mounted with secure locking mechanisms
• Safety Features: Earthing terminals, lockable doors, and internal barriers to prevent accidental contact with live parts

Compliance and Standards

Level 3 distribution boxes in Rwanda must comply with REG Reticulation Standards Version 7, which ensures proper sizing, spacing, and installation practices for medium- and low-voltage distribution equipment . These standards also cover transformer connections, earthing, and protection devices to maintain network reliability and safety.

Practical Considerations

• Ensure the box is installed at a height accessible for maintenance but safe from unauthorized access.
• Verify the number of ways matches the planned feeder circuits.
• Confirm that the box material and IP rating are suitable for local environmental conditions. By adhering to these specifications, Level 3 distribution boxes provide a robust, safe, and standardized solution for electricity distribution in Rwanda .
