Comprehensive Guide to Temporary Power Distribution Boxes
What is a Generator Power Distribution Box?
A generator power distribution box, also known as a temporary power box, is designed to safely distribute power from a generator to multiple outlets or circuits. These boxes are especially important for temporary setups—like construction projects, emergency backups, or outdoor events—where fixed wiring isn’t available or feasible.
Unlike basic extension cords or power strips, these boxes come equipped with GFCI protection, twist-lock inlets, and weatherproof designs. They typically convert high amperage generator output (like 30A or 50A) into multiple household or industrial-grade outlets for safe usage.
Key Features to Look For
When selecting a generator power box, it’s crucial to consider these core attributes:
- Amperage Compatibility (30A or 50A)
- OSHA & NEC Compliance
- Number and Type of Outlets
- GFCI Protection
- Construction Quality (Steel, Aluminum, Weatherproofing)
- Ease of Installation
- Safety Certifications
Each of the listed models below meets these standards and comes from reputable manufacturers with strong safety records.

Make sure to match the power output of your generator to the inlet rating of your chosen box (e.g., 30A or 50A) for safe and effective operation.
Safety Tips for Using Generator Power Boxes
- Always use GFCI-protected outlets, especially in outdoor or damp environments.
- Never overload your generator or power box. Calculate total wattage requirements before plugging in multiple devices.
- Ensure your box is grounded properly as per manufacturer instructions.
- Use weather-resistant enclosures and avoid placing boxes in standing water.
- For residential installation, consult a licensed electrician, especially for through-wall or permanent kits.
