Zambian Lighting Distribution Box Dimensions and Specifications

Zambian lighting distribution boxes are designed for AC 50/60Hz systems, with rated voltages up to 400V and load currents typically up to 100–125A, suitable for residential, commercial, and industrial applications.

General Specifications

Zambian lighting distribution boxes, such as the XRM and YCX6 models, are used for secondary power distribution and control of lighting and electrical equipment. They are suitable for single-phase three-wire or three-phase four/five-wire systems with AC 50/60Hz and rated voltages up to 400V . The boxes provide protection against overload, short circuit, and leakage, ensuring safe operation for both operators and connected equipment .

• Rated Load Current: XRM boxes typically handle up to 100A, while YCX6 boxes can manage total input currents up to 125A, with individual short-circuit protection devices rated up to 63A .
• Enclosure: Fully enclosed metal or plastic-metal hybrid designs, often with measuring instruments, control switches, buttons, and signal indicators mounted on the surface for monitoring and operational efficiency .
• Applications: Widely used in residential buildings, hotels, high-rise buildings, industrial and mining enterprises, hospitals, schools, and government offices .

Dimensions and Design

While exact dimensions vary by manufacturer and model, typical modular lighting distribution boxes in Zambia follow these guidelines:

• Single-gang boxes: For one device, usually compact for wall or ceiling installation.
• Double-gang or multi-gang boxes: For two or more devices, with increased width and depth to accommodate additional breakers or control modules .
• Mounting: Can be installed in technical flooring, false ceilings, or wall recesses, with optimized size for easy handling and maintenance .
• Material: Robust metal or metal-plastic combination for durability, with weatherproof or indoor-rated options depending on the application .

Compliance and Standards

Zambian lighting distribution boxes are designed in accordance with Zambian Standards (ZS 397:2023), which cover electricity supply, distribution, and quality of service . These standards ensure that boxes meet safety, performance, and operational requirements, including proper insulation, protection against electrical faults, and compatibility with local voltage and frequency specifications.

Key Features

• Modular design for flexible installation and expansion.
• Overload and short-circuit protection via MCBs or MCCBs.
• Leakage protection for enhanced safety.
• Surface-mounted indicators for monitoring voltage, current, and operational status.
• Versatile applications across residential, commercial, and industrial environments. In summary, Zambian lighting distribution boxes are modular, safe, and compliant with national standards, with rated voltages up to 400V, load currents up to 125A, and flexible installation options suitable for a wide range of buildings and industrial facilities .
