Leviton 16D31-UB Cam Female Connector 300A 600V Nema 3R

Product Description

The LEVITON 16D31-UB is a single-pole female cam-style plug connector rated for 300 amps and 600 volts, built for demanding temporary and permanent power distribution applications. It features a double set screw termination that accepts wire sizes from 2 AWG to 2/0 AWG, providing a secure, low-resistance connection under high-current conditions. The NEMA 3R enclosure rating means the connector is designed to resist falling dirt, rain, sleet, and snow, making it suitable for outdoor and semi-protected indoor installations. Electricians and temporary power contractors rely on this type of connector for portable distribution equipment, generator hookups, and stage or event power systems.

This connector is intended for use in high-current single-pole power distribution setups where cam-type connectors are the industry standard. Common applications include temporary power distribution panels, generator output connections, load bank hookups, and entertainment or construction site power systems. The blue color coding on this unit follows the standard cam connector color convention used to identify one of the line conductors, helping crews make fast, accurate connections in the field. It is appropriate for both residential service entrance work and commercial or industrial temporary power distribution where 600-volt service is required.

Key Features

• 300-amp continuous current rating for high-load power distribution circuits
• 600-volt rating suitable for single-phase and three-phase service applications
• Double set screw termination accepts 2 AWG to 2/0 AWG conductors for a secure mechanical connection
• NEMA 3R rated for outdoor use, resisting rain, sleet, and falling debris
• Female single-pole cam connector design compatible with standard cam-style distribution systems
• Meets CSA and UL 1691 standards for cam-type connectors

Compatibility

Designed for use in standard single-pole cam-type connector power distribution systems where 300-amp, 600-volt female plug connectors are specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for high-current connectors and temporary power distribution. De-energize and lock out the circuit at the source before making any terminations. Ensure conductor insulation is stripped to the correct length and that both set screws are torqued evenly to achieve a solid mechanical and electrical connection. Inspect the connector body and contact surfaces for damage before placing the connection into service.
