Leviton 16R24-UG 400A 600V Nema 3R Panel Receptacle

Product Description

The LEVITON 16R24-UG is a female panel receptacle rated for 400 amps at 600 volts, 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 feed connections. The enclosure carries a NEMA 3R rating, indicating protection against falling rain and sleet, which allows installation in outdoor or semi-exposed locations. Licensed electricians and electrical contractors install this receptacle in commercial, industrial, and utility panel assemblies where robust, code-compliant connections are required. The unit measures 3.56 inches in length and is finished in green for field identification.

This panel receptacle is used in applications requiring secure, high-ampacity female connections at switchgear, distribution panels, load centers, and service equipment. The NEMA 3R rating makes it appropriate for weatherproof enclosures in outdoor service applications. Its threaded stud design provides a mechanically secure termination that resists vibration and maintains consistent contact pressure under load cycling. Typical installations include commercial service entrances, industrial power distribution equipment, and generator interconnect panels where 400-amp capacity and 600-volt insulation are required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or service equipment fully before installing or servicing this receptacle.
