Leviton 4-Wire 3-Pole Non-NEMA Industrial Grade California Style Locking Plug

The Leviton 4-Wire 3-Pole Non-NEMA Industrial Grade California Style Locking Plug is engineered for power connection applications that call for a secure, twist-locking termination rather than a standard straight-blade plug. Featuring a 4-wire, 3-pole configuration paired with a Non-NEMA California style locking design, this plug is manufactured to Leviton's industrial grade construction standards for durability and dependable performance in demanding commercial and industrial electrical environments. The twist-and-lock engagement mechanism helps resist accidental disconnection in high-vibration, high-traffic, or outdoor work settings, making it a practical choice for facilities and job sites that depend on continuous, secure power delivery. As the plug half of a locking plug-and-connector interface, it is intended to be paired with a compatible Leviton California style locking connector or receptacle sharing the same 4-wire, 3-pole, Non-NEMA configuration.

Key Features

  • 4-Wire, 3-Pole Configuration: Supports circuits that require a dedicated grounding conductor along with three current-carrying conductors.
  • California Style Locking Design: Twist-and-lock engagement helps prevent accidental disconnects during use, unlike a standard straight-blade plug.
  • Non-NEMA Configuration: Designed for specialized, application-specific connection requirements outside common NEMA configurations.
  • Industrial Grade Construction: Built by Leviton to withstand the rigors of demanding industrial, commercial, and job-site environments.
  • Plug-Style Termination: Functions as the male half of a locking plug and connector power interface, intended to mate with a compatible California style locking connector.
  • Leviton Engineering: Backed by Leviton's long-standing reputation for wiring devices used across commercial, industrial, and residential electrical systems.

Technical Specifications

  • List Batch: LEV-20260730

Typical Applications

  • Industrial Power Distribution Equipment
  • Temporary and Portable Power Connections
  • Generator and Backup Power Hookups
  • Commercial and Industrial Facility Wiring
  • Job-Site and Construction Power Setups
  • Renovation and New Construction Electrical Projects

Why Leviton?

Leviton builds its locking devices to industrial grade standards, giving electrical professionals a dependable connection point for demanding power applications.

Leviton CS8365C – Frequently Asked Questions

1) What is the difference between the Leviton CS6365C and CS8365C locking plugs?
Both are 50A, 3-pole, 4-wire California style locking plugs, and the difference is the voltage and phase. The CS6365C is rated 125/250V single phase, which is the common configuration for portable generator and shore-power style hookups. The CS8365C is rated 250V three phase, used where you have three hot legs plus ground. They are not interchangeable with each other, and the mating connector or receptacle has to match the same CS configuration.
2) I need a 3-phase twist lock plug - how does the CS8365C compare to the Pass & Seymour L720P?
The Leviton CS8365C is a 250V 3-phase California style Non-NEMA plug with a 3-pole 4-wire configuration, rated 50A industrial grade. The Pass & Seymour L720P is a Turnlok NEMA L8 locking plug, 3-wire at 480V. The two differ in blade pattern, wire count and voltage class: the CS8365C carries a dedicated grounding conductor as its fourth wire and follows the California style pattern, while the L720P is a 3-wire NEMA L8 device. Match whichever connector or receptacle is already installed on the circuit.
3) Is there a 50 amp locking plug that can be used instead of the Leviton CS6365C or CS8365C California style plug?
The Leviton CS6365C and CS8365C are both 50A California style Non-NEMA locking plugs, in 125/250V 1-phase and 250V 3-phase respectively. The closest 50 amp alternative is the Eaton 7765 industrial armored locking plug, rated 50A 600V/250Vdc with back-wiring and built to an extra heavy duty grade. Note that the Eaton is a NEMA-pattern armored device rather than a California style Non-NEMA blade pattern, so it will not mate with a California style connector or receptacle - the amperage matches but the interface does not.
4) Does a 3-pole 4-wire plug mean three hots and a ground?
Yes. The 3 poles are the current-carrying conductors and the fourth wire is the equipment grounding conductor. On the CS8365C that means three hot legs plus ground for 250V three phase. On the CS6365C, the 125/250V single-phase version, the poles carry two hots and a neutral with ground as the fourth wire. There is no separate isolated neutral beyond that, so it is not suited to circuits needing both a neutral and a full ground on top of three hots.
5) Is this Leviton locking plug rated for job site and generator power hookups?
It is built to industrial grade construction standards and is intended for portable and temporary power, generator and backup power hookups, and industrial power distribution equipment. The twist-lock engagement is what matters on a job site: it resists accidental disconnection under vibration and foot traffic in a way a straight-blade plug will not. Rating is 50A.
6) What should I use for a lighter-duty twist lock circuit instead of a 50 amp California style plug?
The Leviton California style plugs are 50A industrial grade devices for 3-pole 4-wire circuits. For smaller twist-lock loads, several lower-amperage options exist: the Eaton 7411-C safety grip locking plug at 20A 120/208V in heavy-duty specification grade, the Pass & Seymour 2675 rubber dust-tight locking plug at 20A, the Eaton L530P L6-30 two-pole three-wire nylon plug in commercial grade, and the Bryant 4722N angle plug in NEMA L5-15P at 15A 125V. All of these are NEMA-configured rather than California style, so they pair with NEMA receptacles of the matching configuration.
7) For a wet or dusty job site, is the Leviton California style plug the right pick or is there a sealed alternative?
The Leviton California style locking plug is an industrial grade 50A device whose twist-and-lock engagement resists accidental disconnection in high-vibration and outdoor settings, but it is not described as a sealed device. If the environment calls for an enclosure-rated body at a lower amperage, the Pass & Seymour 2675 is a 20A rubber dust-tight locking plug in yellow from the 267 Series, and the Eaton 7765 is an armored 50A 600V/250Vdc plug with back-wiring in extra heavy duty construction. Both are NEMA configurations, so confirm the mating device before substituting.
8) What color is the Leviton CS6365C locking plug housing?
Black. Both the CS6365C and CS8365C come in black only, so there is no color coding to distinguish the single-phase from the three-phase version. Go by the part number and the printed rating on the device, not the housing color, when you have both configurations on the same site.
