Temporary power distribution boxes are built to be rugged yet portable, often featuring carrying handles or optional wheels for mobility. Most units are toolbox-sized, making them easy to move between locations, while larger models may resemble a small storage crate to accommodate higher power loads and multiple outlets . The exact dimensions vary by model, but typical boxes are roughly 12–24 inches in width, 12–24 inches in height, and 8–18 inches in depth, depending on the number of circuits and receptacles .
These boxes can handle single-phase 120/240V or three-phase 208Y/120V and 480Y/277V power sources, with some models supporting up to 3.8 kW or more . They include multiple outlets, such as 20A 125V receptacles, 30A 125/250V inlets, and 60A three-phase connections, allowing them to power everything from small tools to heavy-duty industrial equipment .
Temporary power distribution boxes are made from aluminum, stainless steel, or rugged polymer enclosures to withstand harsh outdoor conditions, dust, moisture, and frequent handling . Many models are weatherproof and meet industry safety standards, with features like GFCI protection, overcurrent protection, and locking covers .
While the exact size depends on the model and power requirements, most temporary power distribution boxes are compact enough to be carried by one or two people, yet large enough to provide multiple outlets and handle significant electrical loads. They are designed for flexibility, durability, and ease of transport, making them ideal for construction sites, outdoor events, and temporary industrial setups .
