Eaton L6-30 Locking Plug, Two-Pole Three-Wire, Nylon

The Eaton L6-30 Locking Plug is a two-pole, three-wire industrial-grade locking connector rated 30A at 250V, built for demanding power-distribution applications that require a secure, vibration-resistant connection. Constructed with a nylon/thermoplastic face and body and featuring Eaton's Ultra Grip design, this severe duty locking connector uses back wiring with brass contacts for dependable conductivity. Available in black and white, it is engineered for industrial environments where a standard locking plug must resist accidental disconnection.

Key Features

  • Locking Configuration: L6-30, two-pole, three-wire (grounding) design for secure, twist-lock engagement in industrial power circuits.
  • Electrical Rating: Rated 30A at 250V for demanding industrial power applications.
  • Durable Construction: Nylon/thermoplastic face and body material for impact resistance and long service life.
  • Back Wiring: Back-wiring method simplifies termination during installation.
  • Ultra Grip Design: Severe duty locking connector special feature provides enhanced grip for easier insertion and removal.
  • Brass Contacts: Brass contact material delivers reliable, low-resistance conductivity.
  • Cord Diameter Range: Accommodates cord diameters of 0.25-0.69 in (6.4 mm-17.5 mm).
  • Operating Temperature: Rated for -20 to 60 °C (-4 to 140 °F) environments.

Eaton L530-P – Frequently Asked Questions

1) What is the difference between the L530-P and L630-P versions of this Eaton locking plug?
Two configurations are offered. Pick the 125V option for MPN L530-P, or the 250V option for MPN L630-P. Both are two-pole, three-wire grounding locking plugs rated 30A, so the choice comes down to the circuit voltage at your receptacle: a 125V twist-lock outlet takes the L530-P, a 250V one takes the L630-P. The two bodies are not interchangeable in the receptacle, so order against the outlet you actually have.
2) What size cord will the Eaton 30A locking plug clamp on?
The cord grip takes outside diameters from 0.25 to 0.69 in (6.4 mm to 17.5 mm). That covers the usual 10/3 and 12/3 SOOW or SJOOW cordage used for 30A twist-lock cordsets. Anything jacketed larger than 0.69 in will not seat in the clamp, and a cord below 0.25 in will not be gripped properly.
3) Can I use this plug on a 30A twist-lock generator or temporary power feed outdoors?
Operating range is -20 to 60 C (-4 to 140 F), with a nylon/thermoplastic face and body for impact resistance, and Eaton lists it as a severe duty locking connector. That suits portable and temporary power, heavy equipment feeds and jobsite cordsets. It is a standard locking plug, not a watertight or dust-tight device, so for washdown or dust-laden service look instead at a sealed type such as the Pass & Seymour 2675 rubber dust-tight locking plug.
4) Will this Eaton plug work on a 480V three-phase machine?
No. It is rated 250V maximum and is two-pole three-wire, so it is a single-phase device. For 480V three-phase at 30A, use an L16-30P type such as the Leviton polarized locking plug; for 480V three-wire, the Pass & Seymour L720P Turnlok is the NEMA L8 option.
5) We need a 30A plug for a 480V three-phase circuit - is the Eaton L6-30 usable?
No. The Eaton L6-30 plug is rated 250V on a two-pole three-wire configuration, so it is a single-phase 250V device. For 30A at 480V three-phase, the Leviton industrial grade polarized locking plug in NEMA L16-30P is the three-phase 480V device. If the circuit is 480V but not 30A three-phase, the Pass & Seymour L720P Turnlok is a NEMA L8 three-wire 480V plug.
6) Is this Eaton locking plug wired from the back, and does that affect how I build the cordset?
Termination is back wiring, so conductors land from the rear of the device and the body closes over them. Strip and dress your leads before you assemble, bring the ground to the green terminal, and set the cord clamp so strain lands on the jacket and not the terminals. Brass contacts carry the current path.
7) Is this a commercial grade or industrial grade locking plug?
Eaton grades this one commercial, with industrial application use and a severe duty Ultra Grip body. If your spec sheet calls out industrial grade specifically, the Leviton locking plugs are listed industrial grade, including the L6-20P 20A 250V and the L16-30P 30A 480V three-phase. Note those are different NEMA configurations, so match the receptacle before substituting.
8) What is the difference between the Eaton L6-30 plug and the Leviton industrial grade locking plugs?
The Eaton L6-30 is listed as commercial grade with a nylon/thermoplastic face and body, brass contacts and back wiring. The Leviton locking plugs such as the L6-20P and L6-15P are listed as industrial grade. Grade is a separate axis from configuration, so match the NEMA configuration first and then decide which grade the environment calls for.
9) The cordset runs in a washdown area - is the Eaton L6-30 the right plug, or is there a sealed option?
The Eaton L6-30 plug is a severe duty locking connector with a nylon thermoplastic body rated -20 to 60 C, but it is a standard locking plug design rather than a sealed one. Where the connection has to resist dust or hose-down, the Pass and Seymour 2675 is a 20A rubber dust-tight locking plug from the 267 Series. Note that it is a 20A device, so it does not substitute on a 30A L6-30 circuit.
10) Is the Bryant 4722N a substitute for the Eaton L5-30 plug on a 125V circuit?
No. The Eaton locking plug is offered in a 125V version as MPN L530-P, which is a 30A configuration. The Bryant 4722N is an angle locking plug in NEMA L5-15P at 15A 125V, so it is a different blade pattern and a lower amperage. It will not engage an L5-30 receptacle.
11) Is there a non-metallic alternative to the Eaton L6-30 locking plug?
The Eaton L6-30 already uses a nylon thermoplastic face and body, so the housing is non-metallic. Bryant's 71020NP is also a non-metallic locking plug, from the 7 Series. Choose between them on the NEMA configuration the receptacle requires rather than on housing material.
12) What color is the Eaton 30A locking plug body?
White is the listed color, with black also produced in this Eaton line. For a plug there is no finish-matching requirement the way there is for a device plate, so color is a labeling or crew-identification choice on cordsets rather than a fit concern.
