Legrand cs8165c Locking Plug 50A 3-phase 480V

Product Description

The LEGRAND cs8165c is a heavy-duty locking plug rated for 50 amps, 3-phase, 480 volts across 4 wires. Manufactured under the Pass and Seymour product line, it uses a Turnlok push-twist-lock body assembly that allows fast, secure terminations without special tooling. The back body slides onto the device and locks with a quarter turn, reducing labor time on temporary and permanent power connections. The plug is molded from nylon for resistance to impact, moisture, and chemicals commonly found in commercial and industrial work environments. Electricians and maintenance crews rely on this device for reliable high-voltage connections in demanding jobsite conditions.

The cs8165c is suited for commercial and industrial applications where 3-phase, 480-volt power distribution is required. Typical installation scenarios include temporary power setups on construction sites, industrial machinery hookups, and generator distribution panels. The quarter-twist locking mechanism keeps the plug firmly seated under vibration and load, reducing the risk of accidental disconnection during operation. Its 4-wire configuration accommodates three hot conductors plus a ground, making it appropriate for standard 3-phase wye and delta distribution systems commonly encountered in commercial electrical work.

Key Features

• Push-twist-and-lock Turnlok body assembly for fast, tool-free installation
• Quarter-twist back body locks in place, reducing assembly time and labor cost
• Nylon construction resists impact, moisture, and harsh jobsite conditions
• Designed for both temporary power and permanent commercial and industrial installations

Compatibility

Designed as an OEM-style locking plug for 50-amp, 3-phase, 480-volt, 4-wire electrical systems in commercial and industrial applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize the circuit and verify absence of voltage with a suitable meter before making or breaking any connections. Confirm conductor sizing, overcurrent protection, and grounding comply with applicable NEC articles for the specific application. Do not exceed the rated voltage or amperage of the device.
