Leviton California Style Locking Plug, 4-Wire, 480V, 50A

The Leviton is an Industrial Grade California Style Locking Plug engineered for demanding 3-Phase power connections in commercial and industrial settings. Referenced by Leviton as the CS8165C, this 4-Wire, 3-Pole, Non-NEMA locking plug is rated 480-Volt, 3-Phase, 50-Amp and finished in a durable Black/White housing for easy identification. Unlike standard NEMA locking devices, the California Style configuration uses a rotating collar to create a secure, vibration-resistant connection that stands up to the mechanical stress of industrial equipment, temporary power setups, and heavy-duty job sites. Built for electrical professionals who need dependable high-amperage connections, this plug delivers the durability and safety expected from Leviton Industrial Grade devices.

Leviton CS82-65C – Frequently Asked Questions

1) Will a Leviton CS8165 California Style plug mate with a NEMA L16-30 or other NEMA twist-lock receptacle?
No. The CS8165C is a non-NEMA California Style device, and its pin-and-sleeve geometry will not engage a standard NEMA locking receptacle. It has to land in a matching California Style connector or receptacle. If your existing outlets are NEMA twist-lock, you need a NEMA plug instead, not this one.
2) What is the difference between the 3-pole and 2-pole versions of the Leviton California Style 50A locking plug?
Two configurations are offered. The 3-pole version is the CS8165C, a 4-wire, 3-pole device for 480V 3-phase circuits feeding motors, machinery, and panel loads. The 2-pole version is the CS82-65C, for circuits that do not carry three phase conductors. Pick by the circuit you are landing on, since the pole count determines which California Style receptacle it will mate with.
3) Is the Leviton CS8165C rated for 480V 3-phase equipment at 50 amps?
Yes. The CS8165C is rated 480 volts, 3-phase, 50 amps in a 4-wire, 3-pole configuration. That covers 3-phase motor and panel feed hookups, plant machinery, and temporary high-amperage job site power. Do not use it on a circuit above that rating.
4) What is the closest alternative to the Leviton CS8165C for a 50A industrial plug if the equipment uses a NEMA configuration instead of California Style?
The Leviton CS8165C is a California Style locking plug, a non-NEMA pin geometry that only mates with California Style connectors and receptacles, so it will not engage a NEMA locking outlet. For a 50-amp industrial plug on a NEMA-style feed, the Eaton 7765 is an industrial armored locking plug rated 50A 600V/250Vdc with back-wiring terminations. Both carry the same 50-amp rating, but the Eaton is an armored back-wired body while the CS8165C uses the California Style rotating collar, and the two will not intermate.
5) I need a locking plug for a 30A 250V single-phase circuit, not 480V three-phase. What should I use?
The Leviton CS8165C is built for 480-volt 3-phase, 50-amp service in a 4-wire, 3-pole California Style pattern, which is more device than a single-phase 250-volt branch needs. For that circuit the Eaton L6-30 locking plug is a two-pole three-wire nylon device in the L6-30 series, a standard NEMA twist-lock rather than California Style.
6) Is this Leviton locking plug industrial grade or just commercial grade?
Industrial grade. The CS8165 California Style plug is built to Leviton's industrial grade standard for plant floors, machine shops, and job site temporary power, where a commercial or residential grade device would not hold up to repeated connects and vibration.
7) Why use a California Style locking plug instead of a standard twist-lock on vibrating equipment?
The California Style design uses a rotating collar that clamps the connection, so it resists accidental disconnection from vibration or equipment movement. That is why it shows up on industrial motors, machinery, and portable job site power where a device can get knocked or shaken loose. The tradeoff is that it will only mate with other California Style devices.
8) What are the alternatives if I need a 50A locking plug but not the California Style configuration?
For a 50A device on a different system, Eaton's 7765 industrial armored locking plug is rated 50A at 600V/600V-class service with 250Vdc, and it uses back-wiring. It is an extra heavy duty device, so it is a fit where you want armored housing rather than California Style geometry. For much lower amperage work, Eaton's L6-30 locking plug is a two-pole three-wire nylon commercial grade device, and the Bryant 4722N is a NEMA L5-15P angle plug at 15A 125V. None of those will mate with a California Style receptacle.
9) Is the Eaton 7411-C a substitute for the Leviton CS8165C on a machine feed?
No. The Eaton 7411-C Safety Grip locking plug is rated 20A at 120/208V and built to Heavy-Duty Specification Grade, so it is a light-duty three-phase device. The Leviton CS8165C is an Industrial Grade California Style plug rated 50A at 480V 3-phase. The amperage, voltage, and mating geometry all differ, so the 7411-C cannot take the place of the CS8165C on a 50-amp 480-volt machine hookup.
10) For a 125V cord cap on portable job-site gear, is there a simpler option than the Leviton CS8165C?
Yes. The Leviton CS8165C is a 50-amp, 480-volt 3-phase California Style plug intended for heavy industrial hookups. For a 15-amp 125-volt cord end, the Bryant 4722N is an angle locking plug in the NEMA L5-15P configuration, a far lighter single-phase twist-lock. It mates to standard L5-15 receptacles rather than California Style devices.
11) What is the difference between the Leviton CS8165C and the Bryant 71020NP locking plug?
The Leviton CS8165C is an Industrial Grade California Style locking plug with a rotating collar, offered in 3-pole (CS8165C) and 2-pole (CS82-65C) configurations for 480V 3-phase 50-amp service. The Bryant 71020NP is a 7 Series non-metallic locking plug. The Bryant uses a non-metallic body in the NEMA-pattern 7 Series, while the Leviton uses the non-NEMA California Style geometry that requires matching California Style mating devices.
12) Does the black and white housing on the Leviton CS8165 mean anything electrically?
No, it is identification only. The black/white housing makes the circuit type easy to spot on a plant floor where several voltages are running side by side. It does not change the 480V 50A rating or the mating configuration.
13) Can I use the Leviton CS8165C for temporary power on a job site?
Yes, that is one of its intended uses. The industrial grade construction and locking collar suit temporary and portable power hookups as well as permanent plant distribution, machine connections, and heavy equipment feeds. You will need California Style connectors on the cord and receptacle side to match.
