Buying Guide: How to Choose a Temporary Power Distribution Box
- Amperage and inlet/outlet options: Assess your max load and ensure the box supports the necessary inlet (50A, 30A, etc.) and the required number and type of outlets (GFCI, straight U-ground, twist-lock).
- Safety features: Look for GFCI protection, circuit breakers for each receptacle, and weather-resistant enclosures suitable for outdoor use.
- Durability and portability: Consider enclosure material (steel vs. non-conductive), weight, and features like handles or stacking capability for easier transport on sites.
- Weather and site conditions: Choose IP or NEMA-rated enclosures if exposure to rain, dust, or chemicals is likely. Grounding and bonding should meet local codes.
- Ease of setup: Units with clearly labeled ports and integrated cooling or ventilation reduce overheating risks during multi-tool operation.
- Expansion and compatibility: If you anticipate scaling up, select a model compatible with additional inlets or a companion distribution box.
