Hubbell CS8164C Locking Connector - 50A 480V 3-Pole 4-Wire, Twist-Lock, Cord Mounted

Overview

The Hubbell CS8164C locking connector is built for demanding industrial environments where secure, high-current power connections matter. With a 50 amp rating at 480V and a 3-Pole 4-Wire grounding configuration, this twist-lock device is designed to support 3-phase delta systems and keep power reliably connected during production runs, maintenance, or setup changes.

Designed for cord-mounted applications, the CS8164C integrates smoothly into existing cable runs while offering a robust locking action that helps prevent accidental disconnections in busy facilities. The combination of its composite body and a high-contrast black and white housing aids quick identification and inspection on crowded shop floors.

Construction, Standards, and Compatibility

This connector carries UL498 recognition, reflecting adherence to widely used electrical safety standards. It is described as non-NEMA in design, which provides flexibility for installations that require an alternative form factor or mounting approach. The 3-Pole 4-Wire grounding setup ensures a defined grounded path for safety and equipment protection.

In everyday use, the CS8164C offers a reliable interface for heavy equipment, motors, or power tools that demand consistent current delivery. The durable composite body supports frequent connect/disconnect cycles and remains resistant to the wear common in industrial settings. The black and white finish contributes to durability while helping technicians quickly locate and verify connections in varied lighting conditions.

Practical Use Cases and Benefits

On factory floors, warehouses, or maintenance bays, you may appreciate the ability to transfer power securely with a twist-lock mechanism. The 50A, 480V rating supports substantial loads, while the 3P4W arrangement provides a grounded configuration for safer operation. The cord-mounted design simplifies integration with existing electrical runs, and the composite construction balances toughness with manageability.
