Leviton 2750 Single Flush NEMA L18-30 Locking Receptacle

The Leviton 2750 is a single flush-mount receptacle built around the NEMA L18-30 locking configuration, designed to give electricians and facility maintenance teams a dependable point of connection for equipment that uses a matching L18-30 locking-type plug. Unlike a standard straight-blade device, the locking pin-and-sleeve style contacts of the L18-30 configuration require the mating plug to be inserted and twisted into place, which helps guard against accidental disconnection in applications where a cord could otherwise be jarred loose or bumped during normal operation. The flush design allows the receptacle to sit cleanly in a standard wallplate opening for a low-profile finished look in the panel, enclosure, or wall location where it is installed, making it a straightforward fit for both new construction and retrofit projects that already call out an L18-30 locking device.

Key Features

  • NEMA L18-30 Configuration: Matches the L18-30 locking-type plug pattern for a secure, twist-lock connection between cord and receptacle.
  • Single Flush-Mount Receptacle: Sits flush for a clean, low-profile installation in a compatible wallplate or enclosure opening.
  • Locking Retention: The twist-to-lock engagement helps resist accidental unplugging from vibration, movement, or an inadvertent tug on the connected cord.
  • Leviton Build Quality: Manufactured by Leviton, a long-established name in wiring devices for commercial and industrial electrical systems.
  • Dedicated Device: A single-receptacle configuration intended for a dedicated connection point rather than a shared multi-outlet layout.
  • Job-Site Familiarity: The L18-30 pattern is a recognized locking configuration, so installers and maintenance staff can identify the correct mating plug at a glance.

Typical Applications

  • Commercial and Industrial Electrical Installations
  • Locking-Plug Equipment Connections
  • Panel, Enclosure, and Wall-Mounted Power Connections

Why Leviton?

Leviton has long been a trusted source for wiring devices used throughout commercial and industrial electrical systems. The 2750 single flush NEMA L18-30 receptacle reflects that focus, giving contractors and facility teams a locking-style connection point built for installations where a secure, dependable plug engagement matters. Choosing a Leviton device for this application means specifying a component from a manufacturer whose wiring devices are a familiar standard on professional job sites, backed by a design intended for consistent, repeatable performance over the life of the installation.

Leviton 2750 – Frequently Asked Questions

1) Can I use the Leviton 2750 as a direct replacement for an existing L18-30 locking receptacle?
That's one of its stated uses. If the device coming out is a flush-mount L18-30 single receptacle, the 2750 drops into the same role and mates with the same plugs already on your equipment cords. Confirm the existing circuit is the 3-phase 4-pole 5-wire arrangement L18-30 uses before you reterminate.
2) What locking plug mates with a Leviton 2750 L18-30 receptacle?
The Leviton 2750 is built around the NEMA L18-30 locking configuration and accepts only a matching L18-30 locking-type plug, which is inserted and twisted into place. Locking plugs built on other NEMA patterns will not engage it: the Eaton L530P is an L6-30 two-pole three-wire plug, the Pass & Seymour L720P is a Turnlok NEMA L8 three-wire 480V plug, and the Bryant 4722N is an angle plug in the NEMA L5-15P configuration. NEMA locking patterns are keyed by blade arrangement, so the cord plug has to carry the L18-30 pattern specifically.
3) I need the cord end, not the wall device - what should I order alongside a Leviton 2750?
The Leviton 2750 is the flush-mount receptacle side of the connection, the device that sits in the wallplate or enclosure opening. The cord-mounted half is a separate locking plug. Comparable locking plugs include the Eaton L530P in L6-30, the Pass & Seymour L720P Turnlok in NEMA L8 at 480V, the Pass & Seymour 2675-2675 267 Series 20A rubber dust-tight plug in yellow, and the Bryant 71020NP 7 Series non-metallic plug. Match the plug's NEMA configuration to the receptacle you are wiring rather than to the brand.
4) Will the Leviton 2750 fit a standard wallplate opening?
Yes. The 2750 is a flush-mount single device sized to sit in a standard wallplate opening for a low-profile finish. The wallplate itself is not part of the device, so order a plate cut for the L18-30 flush receptacle pattern along with it.
5) Why specify a twist-lock receptacle instead of a straight-blade one for equipment power?
Twist-lock contacts have to be inserted and rotated to seat, so a bumped or tugged cord won't drop the connection the way it can on a straight-blade device. That's the reason the 2750 gets specified for equipment in traffic areas, on vibrating machinery, and anywhere an unplanned disconnect shuts a process down. A straight-blade receptacle is fine for general convenience power where nothing depends on retention.
6) I need the cord-end locking plug, not the receptacle. What else do you carry?
ZenSupply stocks locking plugs across several configurations, so match the plug to the circuit you're wiring. For 30A two-pole three-wire 250V work there's the Eaton L6-30 locking plug in nylon, commercial grade. For 125V 15A there's the Bryant 4722N angle locking plug, NEMA L5-15P. Heavier industrial needs are covered by the Eaton 7765 armored locking plug, 50A 600V/250Vdc with back wiring, extra heavy duty, and the Eaton 7411-C Safety Grip plug at 20A 120/208V, heavy-duty specification grade. For wet or dusty locations, the Pass & Seymour 2675 is a 20A rubber dust-tight locking plug in yellow.
7) We have a 50A 600V machine feed - is the Leviton 2750 the right locking device?
The Leviton 2750 is an L18-30 configuration device, so it is matched to equipment cords carrying an L18-30 locking plug. For a heavier industrial connection, the Eaton 7765 is an industrial armored locking plug rated 50A 600V/250Vdc with back-wiring terminations and is catalogued as extra heavy duty. Confirm the configuration called out on the equipment nameplate or the drawing before choosing between them, since the plug and receptacle must share the same NEMA pattern.
8) Does a flush device like the Leviton 2750 work in a wet or washdown area?
The Leviton 2750 is a single flush-mount receptacle designed to sit in a standard wallplate opening for a low-profile finish in a panel, enclosure, or wall location, with the twist-lock engagement resisting accidental disconnection from vibration or a tug on the cord. If the connection point is exposed to dust or moisture, the cord end matters too: the Pass & Seymour 2675-2675 is a 267 Series 20A rubber dust-tight locking plug in yellow, and the Eaton 7411-C Safety Grip plug is a 20A 120/208V device in heavy-duty specification grade. Verify the enclosure and cover rating for the environment with the specifying engineer.
9) Can I use a 15A or 20A locking plug on the same circuit as a Leviton 2750?
No - NEMA locking configurations are not interchangeable across ampere ratings. The Leviton 2750 carries the L18-30 pattern and will only accept an L18-30 plug. Lower-rated locking plugs such as the Bryant 4722N, a 15A 125V angle plug in NEMA L5-15P, or 20A devices like the Eaton 7411-C Safety Grip plug at 120/208V and the Pass & Seymour 2675-2675 267 Series 20A plug use different blade patterns and belong on circuits wired for those configurations.
10) Is the Leviton 2750 a multi-outlet device or a single outlet?
Single outlet. It's built as a dedicated connection point for one piece of equipment, not a duplex or shared multi-outlet layout. If you need two L18-30 drops, you're running two devices.
11) What is the Leviton part number to order for the single flush L18-30 receptacle?
Order Leviton 2750. That is the manufacturer part number for the single flush-mount NEMA L18-30 locking receptacle, and it is the only model on the item.
12) What is a lighter-duty locking device if the Leviton 2750 is more than the application needs?
The Leviton 2750 is a single-receptacle device intended as a dedicated L18-30 connection point rather than a shared multi-outlet layout. Where a smaller single-phase locking connection will do, the Bryant 4722N is an angle locking plug in NEMA L5-15P at 15A 125V, the Bryant 71020NP is a 7 Series non-metallic locking plug, and the Eaton L530P is an L6-30 nylon two-pole three-wire plug listed as commercial grade. These are cord-end devices in different NEMA patterns, so the matching receptacle has to change with them.
