Leviton Telcom 4770-B Locking Plug 15A 277V

Product Description

The LEVITON TELCOM 4770-B is a locking plug rated for 15 amps and 277 volts in a 2-pole, 3-wire grounding configuration. This twist-lock style plug is designed for secure electrical connections in applications where accidental disconnection is not acceptable. The grounding conductor provides an additional layer of fault protection. Licensed electricians install this plug in commercial and industrial branch circuit wiring where a positive locking connection is required.

This plug is suited for commercial lighting circuits, industrial equipment hookups, and other demanding environments where a standard straight-blade connection is insufficient. The 277-volt rating makes it a common choice for single-phase commercial fluorescent and LED lighting circuits fed directly from a 480Y/277-volt distribution system. The 2-pole, 3-wire grounding configuration meets typical requirements for these branch circuit terminations.

Key Features

• Twist-lock design prevents accidental disconnection under load or vibration
• 15-amp, 277-volt rating suitable for commercial lighting branch circuits
• 2-pole, 3-wire grounding configuration for fault protection
• Sold individually as a single unit replacement or new-installation plug

Compatibility

Designed as an OEM-style locking plug for use with compatible twist-lock receptacles rated for 2-pole, 3-wire grounding service at 15 amps and 277 volts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit at the panelboard before terminating conductors. Verify conductor gauge is appropriate for the 15-amp circuit rating before making connections. Do not exceed the voltage or amperage ratings marked on the plug body.
