Leviton 16D23-UR Cam Male Plug 400A 600V 1/0-4/0 Awg Nema 3R

Product Description

The LEVITON 16D23-UR is a single-pole male cam-style plug connector rated for 400 amps at 600 volts. It accepts wire sizes from 1/0 to 4/0 AWG and uses a single set screw termination method for a secure, low-resistance connection. The connector carries a NEMA 3R enclosure rating, making it suitable for outdoor and semi-protected environments where exposure to rain and sleet is a concern. At 7.01 inches in overall length and finished in red for easy circuit identification, this plug is built for industrial power distribution, temporary power hookups, and high-amperage service connections installed by licensed electricians and qualified power distribution technicians.

The 16D23-UR is used in applications requiring high-current single-pole connections, including portable generator hookups, stage and event power distribution, industrial equipment feeds, and temporary construction power systems. The cam-style locking design provides a positive mechanical engagement that resists accidental disconnection under load. The NEMA 3R rating makes it appropriate for exterior electrical enclosures, outdoor switchgear, and job-site distribution equipment where weatherproofing is required but full submersion is not a factor.

Compatibility

Designed as an OEM-style replacement or new-installation cam connector for single-pole 400 amp power distribution systems using 1/0 to 4/0 AWG conductors in NEMA 3R-rated enclosures and assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before terminating or disconnecting any cam connector. Insert the conductor fully into the barrel and tighten the set screw to the connector manufacturer's guidelines using an appropriately sized hex key. Verify polarity and color-code conventions with the mating connector body before restoring power.
