Leviton Telcom 2746 Locking Outlet Flanged 3P 4W

Product Description

The LEVITON TELCOM 2746 is a flanged locking outlet configured for 3-pole, 4-wire, 3-phase electrical service in the NEMA L17 series. Flanged outlets are designed for panel or enclosure mounting, providing a fixed receptacle point where a twist-lock plug can be secured under load. This type of device is typically installed in industrial, commercial, and heavy-duty electrical distribution applications where a secure, vibration-resistant connection is required. Licensed electricians handle installation as part of branch circuit wiring for machinery, generators, and portable equipment hookups.

This outlet is suited for 3-phase power distribution panels, generator transfer switch assemblies, and equipment panels in commercial or light industrial facilities. The L17-series designation indicates compatibility with twist-lock wiring devices following the NEMA L17 configuration, which is used in applications requiring a dedicated 3-phase, multi-wire circuit with a locking retention mechanism. Installation is performed during panel construction, equipment room buildouts, or generator connection setups where a stable, code-compliant outlet point is needed.

Key Features

• Flanged mounting design for direct panel or enclosure installation
• 3-pole, 4-wire configuration supports 3-phase power distribution
• NEMA L17-series locking outlet for twist-lock plug retention
• Single-unit packaging suitable for individual circuit or outlet point installations

Compatibility

Designed as an OEM-style replacement or new-installation flanged locking outlet for 3-phase electrical distribution panels and enclosures requiring a NEMA L17-series, 3-pole, 4-wire twist-lock outlet.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify absence of voltage with a calibrated meter before working on any wiring connections. Ensure the panel or enclosure knockout or mounting hole is properly sized and deburred before seating the flanged outlet. Follow NEC requirements for conductor sizing, grounding, and conduit fill applicable to the circuit ampacity and installation environment.
