Hubbell CS8364L 50A 250V 3-Phase 4-Wire Twist-Lock Connector For Sale

The HUBBELL CS8364L is a twist-lock electrical connector rated for 50 amps at 250 volts in a 3-phase, 4-wire configuration. This heavy-duty connector is designed for industrial and commercial power distribution applications where a secure, locking connection is required. The twist-lock design prevents accidental disconnection under load, making it well-suited for temporary power setups, generator hookups, and portable equipment feeds. Licensed electricians install this connector as part of branch circuit wiring on job sites, in industrial facilities, and at commercial venues requiring high-amperage 3-phase power.

The CS8364L fits into applications where 3-phase, 4-wire power at 250 volts is required, including temporary construction power, generator output connections, and industrial machinery feeds. Its 50-amp rating supports high-draw equipment common in manufacturing, event power, and large commercial HVAC installations. This connector is typically paired with a matching inlet or receptacle in the same CS series configuration to complete a secure power circuit.

• Twist-lock engagement prevents accidental disconnection under load
• Heavy-duty construction suited for commercial and industrial environments
• Compatible with CS series inlets and receptacles in matching as an OEM-style replacement or installation connector for 3-phase, 4-wire twist-lock wiring systems in commercial and industrial power distribution circuits rated at 50 amps and 250 volts.
  Installation Notes

  Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit at the panel before making or breaking any connections. Verify that the source voltage, phase configuration, and ampacity match the connector rating before wiring. Do not exceed the 50-amp continuous load rating of the connector.
