Mobile power distribution boxes vary in size, with common dimensions ranging from 37 × 34 × 33 cm to 570 × 570 × 685 mm.

Typical Dimensions

• Compact Mk2 Distribution Box: 570 mm × 570 mm × 685 mm high, designed for stacking to save storage space and suitable for construction, industrial, mining, and event applications .
• SAA Portable Distribution Box (240V): 37 cm × 34 cm × 33 cm, featuring overcurrent protection, waterproof design, and a handle for portability, ideal for stage and event environments .

Material and Design Considerations

Many mobile power distribution boxes are made from rubber or solid rubber composites for durability, impact resistance, and electrical insulation . Some models use IP66-rated enclosures to ensure protection against dust and water ingress . The boxes often include MCB, RCD, or RCBO breakers for circuit protection, and their design allows for practical handling, stacking, and flexible component fitting .

Applications

These boxes are widely used in temporary power setups, including construction sites, trade fairs, events, and industrial maintenance. The choice of size depends on the number of circuits, power rating, and portability requirements. Smaller boxes like the SAA model are easier to transport, while larger boxes like the Mk2 provide more outlets and higher current capacity. In summary, mobile power distribution boxes come in a range of sizes, from compact units around 37 × 34 × 33 cm to larger stackable units measuring 570 × 570 × 685 mm, with materials and features tailored to safety, durability, and application needs .
