Leviton 16R22-UR Panel Receptacle 400A 600V Nema 3R

Product Description

The LEVITON 16R22-UR is a female panel receptacle rated for 400 amps at 600 volts, designed for heavy-duty power distribution applications in industrial and commercial environments. It accepts wire sizes from 1/0 to 4/0 AWG via a double set screw termination method, providing a secure, low-resistance connection under high-current load. The enclosure carries a NEMA 3R rating, making it suitable for outdoor and semi-protected indoor locations where exposure to rain, sleet, and ice is possible. Licensed electricians install this receptacle as a fixed panel-mount power inlet, typically in temporary power distribution systems, construction site panels, and portable generator hookups.

This receptacle is suited for both residential service applications and commercial or light industrial installations where a rated, weatherproof female panel connector is required. The NEMA 3R rating makes it a common choice for outdoor disconnect panels, generator transfer switch enclosures, and portable distribution equipment. The double set screw termination supports the full wire range from 1/0 to 4/0 AWG, accommodating the large-gauge feeders common in 400-amp service runs. Red color aids in visual identification of high-amperage circuits on job sites and in multi-circuit panel assemblies.
