Legrand CS6377 Locking Inlet 3-wire 50A 250V

Product Description

The LEGRAND CS6377 is a 3-wire locking inlet rated for 50 amps at 250 volts. It provides a secure, twist-lock connection point for temporary or permanent power applications where a reliable, high-amperage connection is required. The CS6377 is a flush-mount or surface-mount inlet used to receive a locking plug in industrial, commercial, and heavy-duty residential settings. Licensed electricians install this device as part of a fixed wiring assembly, typically at generator connection points, transfer panels, or other high-current power entry locations.

This inlet is suited for applications requiring a NEMA L6-50 style locking configuration. Common install scenarios include standby generator hookups, portable power distribution panels, and industrial equipment connection points where accidental disconnection must be prevented. The twist-lock design keeps the mating plug secured under load, making it appropriate for environments with vibration or high-cycle use.

Key Features

• 50-amp, 250-volt rating supports high-current power delivery
• 3-wire locking configuration prevents accidental plug disconnection
• Twist-lock retention mechanism suitable for high-cycle and vibration-prone environments
• Designed for flush or surface mounting in fixed wiring assemblies
• Compatible with matching locking plugs per NEMA L6-50 configuration

Compatibility

Designed as an OEM-style replacement or new-installation locking inlet for 3-wire, 50-amp, 250-volt locking wiring systems in commercial and industrial electrical applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify zero voltage with a meter before beginning any wiring work. Use appropriately rated conductors and enclosures sized for a 50-amp, 250-volt circuit. Secure the inlet to a listed enclosure or surface as required by local code.
