Midwest Tool U038C010 100A Temporary Power Outlet Nema 3R

Product Description

The MIDWEST TOOL U038C010 is a 100-amp, 1-phase unmetered temporary power outlet designed for construction site and job site power distribution. Built in a NEMA 3R-rated G90 galvanized steel enclosure with a zinc-coated finish, it provides weatherproof protection for outdoor temporary service applications. The unit comes factory wired and assembled with three receptacle positions and three circuit breakers, ready for surface mounting. It carries UL and CUL listings and meets NEMA and NEC applicable standards at a voltage rating of 120/240 volts. Licensed electricians install and connect this unit during temporary service setup on residential and commercial construction projects.

The U038C010 is suited for temporary electrical service panels on construction sites where a metered service is not required. The left position hosts a 6-20R receptacle, while the center and right positions each carry a 5-20R2GFCI receptacle, providing GFCI protection on the 120-volt circuits. The three circuit breaker positions consist of two CB220 breakers and one CB120 breaker. All terminals accept copper or aluminum conductors, and loop-feed terminals allow for maximum wiring flexibility across a broad range of wire sizes. The enclosure features concentric knockouts to accommodate varied wiring needs.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and all applicable local codes. Confirm the utility or generator supply is de-energized and locked out before making any wiring connections. The enclosure is rated for surface mounting and the NEMA 3R enclosure is suitable for outdoor use, but it should be positioned to minimize direct water exposure where possible. Verify conductor sizing against the wire range specifications before terminating line, load, neutral, and ground conductors.
