Construction site power distribution is typically organized in three levels: the main distribution board, distribution boxes, and switch boxes. The main distribution board is installed close to the incoming power supply, while distribution boxes are positioned near areas with concentrated electrical equipment or loads. Switch boxes are located below distribution boxes, and the horizontal distance between a switch box and the equipment it controls should not exceed 3 meters. The distance between a distribution box and its switch box should generally be less than 30 meters to ensure efficient power delivery and safety .
Distribution boxes must be installed in ventilated, dry, and temperature-stable locations, avoiding areas exposed to gas, smoke, steam, liquids, vibration, impact, or heat sources. Adequate space should be provided around the boxes to allow two people to work simultaneously without obstruction, and no items, weeds, or shrubs should block access .
The bottom edge of a distribution box is usually set between 1.5 and 1.8 meters above the ground, which facilitates operation and inspection. Boxes should be firmly fixed using mounting brackets or screws to prevent movement or tilting due to vibration or accidental impact .
Distribution boxes are typically made of iron plate or high-quality insulating material, with metal parts electrically connected to the protective grounding system. Inside, electrical equipment is mounted on insulated plates, and all wiring should use insulated, high-temperature-resistant wires with secure connections. Protective neutral wires and leakage protection devices are installed to enhance safety .
On dynamic construction sites, distribution boards are often weatherproof, shock-resistant, and mobile, allowing them to be relocated as site power needs change. They serve as central hubs, dividing incoming electricity into multiple circuits for tools, lighting, and machinery, and include components like main breakers, outgoing circuit breakers, sockets, and residual current devices (RCDs) for safety .
In practice, distribution boxes are located to balance accessibility, safety, and efficiency, ensuring that power is delivered reliably to all site equipment while minimizing hazards. Proper placement, secure installation, and adherence to environmental and safety standards are essential for effective construction site electrical management .
