Construction power distribution box with metering

Construction power distribution boxes with metering provide safe, temporary electricity distribution on worksites while allowing energy monitoring.

Key Features

Amperage and Voltage Ratings: Construction distribution boxes typically range from 30A to 400A depending on the site requirements. Smaller boxes for light-duty use often operate at 110–120V with branch circuits rated around 20A, while larger industrial boxes can handle 160–400A for heavy machinery and multiple circuits . Built-in Metering: Many boxes include multifunctional electricity meters or transformer measurement panels to monitor energy consumption in real time. This is essential for tracking usage on construction sites, fairgrounds, or temporary installations . Safety Protections: These boxes are equipped with circuit breakers for each outlet, leakage protection, and sometimes main disconnect switches. This ensures protection against overloads, short circuits, and electrocution . Durability and Weather Resistance: Construction boxes are designed for harsh environments. They often feature thick metal or high-quality ABS plastic enclosures, double insulation, and waterproof ratings such as IP44, IP54, or IP65. This allows safe outdoor use in rain, dust, or snow . Installation and Mobility: Many units are wall-mounted or freestanding, with pre-wired interiors for easy setup. Mobile distribution cabinets are available for temporary sites, allowing quick deployment and relocation . Customization and Industrial Use: For larger projects, manufacturers like ELSTA Mosdorfer and TopCabinet offer modular cabinets with multiple meter panels, lockable compartments, and options for single-phase or three-phase systems. These can be tailored for construction sites, photovoltaic systems, or commercial installations .

Applications

• Construction Sites: Temporary power for tools, lighting, and machinery.
• Industrial Projects: Sub-distribution and metering for high-energy equipment.
• Outdoor Events: Fairgrounds, campsites, and marketplaces requiring monitored power.
• Renewable Energy Installations: Solar or wind projects needing accurate energy measurement.

Summary

A construction power distribution box with metering combines safe power distribution, real-time energy monitoring, and robust protection for temporary or industrial sites. When selecting a unit, consider amperage, voltage, number of outlets, metering type, environmental protection rating, and mobility to match the specific requirements of your worksite .
