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

Product Description

The LEVITON 16R23-UG is a male panel receptacle rated for 400 amps at 600 volts, built for heavy-duty industrial and commercial power distribution applications. The threaded stud termination accepts wire from 2 AWG up to 4/0 AWG, providing flexibility across a range of feeder and service conductor sizes. The unit carries a NEMA 3R enclosure rating, meaning it is designed to withstand falling rain and sleet, making it suitable for outdoor or semi-protected installations. Overall length is 2.72 inches. Licensed electricians and electrical contractors typically install this receptacle in panel or enclosure assemblies where high-current connections must remain weatherproof and mechanically secure.

This receptacle is intended for use in electrical panels, switchgear enclosures, and power distribution assemblies in commercial, industrial, and utility service environments. The NEMA 3R rating qualifies it for outdoor use in locations subject to rain and ice formation without direct submersion. It is well suited for service entrance panels, motor control centers, and portable power distribution systems where a robust 400-amp connection point is required. Its green color coding aids in quick visual identification during installation and inspection.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Confirm that the panel or enclosure is fully de-energized and locked out before mounting or terminating the receptacle. Conductors must be torqued to the enclosure or connector manufacturer specifications using an appropriate lug torque tool. The threaded stud termination requires a properly rated compression lug or mechanical connector sized for the conductor being terminated.
