Midwest Tool U013 Unmetered Power Outlet 30A Nema 3R

Product Description

The MIDWEST TOOL U013 is a 30-amp, single-phase unmetered power outlet designed for surface mounting in temporary or permanent electrical distribution applications. Built with G90 galvanized steel and a zinc-coated finish, the enclosure meets NEMA 3R standards for outdoor and wet-location use. The unit is rated at 120 volts and accepts a center-position R32U receptacle configuration. All components arrive factory wired and assembled, reducing field labor time. UL and CUL listed, the U013 complies with NEMA and NEC applicable standards. Licensed electricians install this unit in construction sites, utility pedestals, and similar temporary power setups.

The U013 is suited for residential and light commercial temporary power applications where a compact, weatherproof single-phase outlet is required. Its surface-mount design fits standard construction-site and utility installations. The enclosure accepts a broad range of concentric knockouts to accommodate varied conduit and wiring entry needs, and loop-feed terminals allow maximum circuit flexibility for field wiring configurations.

Compatibility

Designed as an OEM-style surface-mount unmetered power outlet compatible with single-phase 120-volt temporary and permanent power distribution installations meeting NEMA and NEC requirements.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all upstream power sources before wiring or servicing the unit. The NEMA 3R enclosure is rated for outdoor use but should be mounted to a solid, plumb surface to maintain proper weatherproofing. Verify wire gauge selection matches the branch circuit load and follows NEC ampacity tables for the conductor material and installation method used.
