Portable three-level distribution boxes are typically compact, modular units designed for easy transport, with approximate dimensions ranging from 600–900 mm in height, 400–600 mm in width, and 300–500 mm in depth.

General Specifications

Portable three-level distribution boxes are engineered for temporary or mobile power distribution, often used in industrial, entertainment, or construction settings. They are designed to house multiple circuit breakers or outlets across three vertical levels, allowing for organized and safe distribution of power .

• Height: Usually between 600 mm and 900 mm, depending on the number of levels and internal components.
• Width: Typically 400 mm to 600 mm, providing enough space for multiple outlets or breakers per level.
• Depth: Commonly 300 mm to 500 mm, allowing for wiring, busbars, and ventilation.
• Weight: Varies with material and amperage rating; lightweight designs use steel or aluminum for portability.

Design Features

• Modular Levels: Each of the three levels can accommodate circuit breakers, RCBOs, or outlets, often configurable for 16A–32A loads .
• Portability: Equipped with handles or wheels for easy transport, suitable for indoor and outdoor use .
• Safety Certifications: Many units comply with CE, UL, or CB standards, ensuring safe operation under temporary conditions .
• Compact Layout: Space-saving design allows stacking of components while maintaining accessibility for maintenance and operation .

Practical Considerations

When selecting a portable three-level distribution box, consider:

• Amperage and voltage requirements to ensure the box can handle the intended load.
• Number of outlets or breakers per level to match your equipment needs.
• Transport and storage space to accommodate the box's height, width, and depth.
• Environmental conditions such as moisture or dust, which may require IP-rated enclosures. These dimensions and features provide a practical guideline for planning installation, transport, and operational use of portable three-level distribution boxes in temporary or mobile power setups.
