Leviton 16R23-UR Panel Receptacle 600V 400A Nema 3R

Product Description

The LEVITON 16R23-UR is a male panel receptacle rated for 600 volts and 400 amps, designed for heavy-duty electrical distribution applications. It features a threaded stud termination method and accepts wire sizes from 2 AWG up to 4/0 AWG, making it suitable for high-current service entrance and panel connections. The receptacle carries a NEMA 3R rating, indicating it is built to withstand outdoor exposure including rain and sleet. Licensed electricians install this component in industrial, commercial, and utility settings where robust, weatherproof power connections are required at panel enclosures.

This panel receptacle is suited for use in outdoor-rated electrical enclosures, load centers, and service entrance equipment where a secure, high-amperage male connection point is needed. The NEMA 3R rating makes it appropriate for installations exposed to the elements, such as exterior distribution panels, meter bases, and weatherproof disconnect enclosures. The color is red, which aids in visual identification of the connection point. It ships as a single unit and is commonly specified in commercial and light industrial electrical work.
