Power Distribution Units expertly designed for maximum power in a compact unit, are easily portable and self-contained. Importance of internal wiring connection from the breaker to the receptacle in a safely enclosed easily mobile unit is optimal when it comes to running large power tools and machinery on the job site.


Easily Portable and Completely Self-Contained

Our high-grade Power Distribution Units are engineered with Type 3R construction standard in compliance with NEMA, JIC, NEC, UL and other industry standards to ensure industry regulatory approval. The power distribution unit includes a padlock hasp, beneficial for safety and compliance. Enclosures built with 12-gauge cold rolled steel construction protect electrical and wiring and ensure safety while in proximity to large machinery.

Reliable Internal Wiring Connection from the Breaker to the Receptacle

Loss of power is unacceptable in many mission-critical operations. The Portable Distribution Units are built with all internal wiring and stacked within a tall and lean durable design including wiring connection to the receptacle. For high heat on the job site, the unit includes an integral transformer fan with thermostat for the high ambient temperature to cool down.
