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

Product Description

The LEVITON 16R23-UB is a male panel receptacle rated for 400 amps at 600 volts, designed for high-capacity electrical connections in enclosures and panels exposed to outdoor or wet environments. The threaded stud termination method accepts wire sizes from 2 AWG up to 4/0 AWG, making it suitable for large feeder and service entrance applications. Its NEMA 3R rating means the housing resists rain, sleet, and external ice formation. At 2.72 inches in overall length and finished in blue for polarity or circuit identification, this receptacle is installed by licensed electricians working on commercial, industrial, or utility power distribution equipment.

This panel receptacle is used in applications where a secure, high-amperage connection point is required on an enclosure wall or panel dead-front. Typical install scenarios include temporary power distribution panels, generator connection points, portable equipment hookups, and industrial machinery feeds. The NEMA 3R rating qualifies it for outdoor enclosures that require protection from precipitation but do not need full weathertight sealing. It is well suited for both permanent panel installations and temporary service connections at construction sites or industrial facilities.

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 enclosure before mounting or terminating this receptacle. Ensure conductor lugs and hardware are torqued per the conductor and lug manufacturer specifications. Verify that the enclosure maintains its NEMA 3R integrity after cutout and installation to preserve environmental protection.
