Leviton 2340 NEMA L8-20 Locking Receptacle, Single, 20A

The Leviton 2340 is a single NEMA L8-20 locking receptacle rated 20A, built to deliver a secure, twist-lock connection for demanding electrical circuits. Designed for use where accidental disconnects cannot be tolerated, this locking-style device pairs with a compatible NEMA L8-20 locking plug to keep equipment connected under vibration, movement, or incidental cord pull. As a single receptacle configuration, the Leviton 2340 is well suited for dedicated circuit applications in commercial, industrial, and institutional settings where a NEMA L8-20 locking connection is specified.

Key Features

  • NEMA Configuration: NEMA L8-20 locking configuration ensures the receptacle mates only with the correct locking plug, reducing the risk of cross-connection with incompatible devices.
  • Locking Design: Twist-lock engagement secures the mating plug in place, helping prevent accidental disconnection in applications subject to vibration or cord strain.
  • Amperage Rating: Rated 20A for dedicated-circuit loads consistent with NEMA L8-20 applications.
  • Single Receptacle: Configured as a single receptacle device for straightforward installation on a dedicated NEMA L8-20 circuit.
  • Leviton Build Quality: Manufactured by Leviton, a recognized supplier of wiring devices for professional electrical installations.

Leviton 2340 – Frequently Asked Questions

1) I need a locking receptacle but my equipment is 125/250V, not 480V. What should I look at instead?
Then skip the L8-20. For a 125/250V four-wire cord, the matching device is an L14-20, and ZenSupply carries the Eaton L14-20 industrial locking receptacle in black nylon, commercial grade. For a 125V two-pole cord on a small load, the Eaton NEMA L1-15 locking receptacle is the low-amp option. Match the NEMA letter-number on the equipment cord cap, not just the amp rating.
2) Can an Eaton L14-20 locking receptacle be used in place of the Leviton 2340?
No. The Leviton 2340 is a NEMA L8-20 configuration rated 480V, 20A, while the Eaton L14-20 industrial locking receptacle is a NEMA L14-20 configuration in a black nylon body. L8-20 and L14-20 have different blade patterns and serve different circuit types, so an L8-20 plug will not mate with an L14-20 receptacle. If the equipment cord ends in an L8-20 plug, the 2340 is the matching device; if it ends in an L14-20 plug, use the Eaton L14-20.
3) Which of these locking receptacles is rated for a 480V circuit?
The Leviton 2340 carries a 480V rating in a NEMA L8-20, 20A single locking configuration, which is the pattern used for 480V two-pole three-wire grounding circuits. The Eaton 7540 is a NEMA L1-15 device and the Eaton L14-20 is a NEMA L14-20 device, both of which are different configurations serving different circuit arrangements. For a 480V L8-20 feed, the 2340 is the device that matches.
4) Why use a locking receptacle instead of a standard straight-blade one for equipment power?
The twist-lock engagement holds the plug mechanically, so vibration, equipment movement or an incidental pull on the cord will not drop the connection. On a straight-blade device the cord can walk out under the same conditions. That is the reason the 2340 gets specified for dedicated circuits feeding commercial and industrial equipment where an unplanned disconnect is not acceptable.
5) Is the Leviton 2340 a single receptacle or a duplex?
Single. The 2340 is a one-outlet locking device, which is how a dedicated circuit is normally served, one load, one receptacle. If you need two separately corded pieces of equipment on the same outlet box, you need two devices and the circuits to match, not this one.
6) What is the Leviton part number and model to order for an L8-20 locking receptacle?
Order Leviton model 2340. That is the manufacturer part number, and the single model offered for this NEMA L8-20 20A receptacle.
7) Can I use the Leviton 2340 outdoors or on a piece of equipment housing?
The 2340 is a standard-mount single locking receptacle intended for installation on a dedicated L8-20 circuit in commercial, industrial and institutional work. It is not supplied as a flanged outlet for mounting through equipment sheet metal. If you need a flanged body, look at a flanged locking receptacle such as the Bryant 71020ER from the 7 Series. For wet or damp locations, the enclosure or weatherproof cover is a separate item you specify with it.
8) How many conductors does an L8-20 circuit need for the Leviton 2340?
L8-20 is a three-pole, three-wire configuration, so the 2340 lands three current-carrying conductors (no neutral) plus no separate equipment ground blade, which is why it is used on 480V three-phase delta or two-pole 480V equipment feeds rather than on anything needing a neutral. If your load needs a neutral at 480V, an L8-20 is the wrong configuration for the job.
9) What locking receptacle should I use for a small 15A twist-lock cord instead of the Leviton 2340?
For a 15A twist-lock cord, the Eaton 7540 is a NEMA L1-15 locking receptacle in commercial grade. The Leviton 2340 is a NEMA L8-20 single locking receptacle rated 20A at 480V, which is a different and higher-voltage configuration. Match the receptacle to the plug configuration stamped on the cord cap: L1-15 cords to the Eaton 7540, L8-20 cords to the Leviton 2340.
10) I need a locking receptacle that mounts to a flanged inlet plate on equipment, not a standard wall box. What is the alternative to the Leviton 2340?
Look at the Bryant 71020ER, a 7 Series flanged locking receptacle. A flanged device is designed to be surface mounted through a cutout in equipment housing or a panel face. The Leviton 2340 is a single locking receptacle in NEMA L8-20 configuration intended for conventional device-box installation on a dedicated circuit. Confirm the Bryant unit's configuration matches your plug before ordering, since the 2340 is specifically L8-20.
