Leviton Single Locking Receptacle, Industrial Grade, California Style Non-NEMA

The Leviton Single Locking Receptacle (model CS816-9) delivers industrial-grade power connectivity for demanding commercial and industrial electrical systems. Configured to the California Style Non-NEMA standard, this flush-mount, impact-resistant receptacle is rated 50-Amp, 480-Volt AC, 3-Phase, making it well suited for heavy-duty equipment, machinery, and power-distribution circuits found in industrial plants, manufacturing facilities, and commercial job sites. Its black, industrial-grade housing is engineered to withstand rugged jobsite and plant-floor conditions while maintaining a secure, vibration-resistant locking connection that reduces the risk of accidental disconnects under load.

Key Features

  • Amperage Rating: 50-Amp capacity supports high-current industrial power distribution and heavy equipment loads.
  • Voltage & Phase: 480-Volt AC, 3-Phase configuration for heavy industrial and commercial power circuits.
  • Locking Connection: Single locking receptacle design in California Style Non-NEMA configuration for a secure, vibration-resistant connection that resists accidental disconnection.
  • Flush Mount Design: Flush mounting profile allows clean, low-profile integration into panels, enclosures, and industrial equipment surfaces.
  • Impact-Resistant Construction: Impact-resistant housing built to withstand rough industrial handling, drops, and demanding jobsite conditions.
  • Industrial Grade: Industrial grade rating designed for the rigors of continuous commercial and industrial duty cycles.
  • Housing Color: Black housing for easy visual identification on industrial equipment and panels.
  • Model Options: Available in CS816-9-P and CS8269 configurations to match mating plug and connector requirements.

Leviton CS816-9 – Frequently Asked Questions

1) What is the difference between the Leviton CS816-9 and CS8269 California style locking receptacles?
The wiring configuration is the whole difference. CS816-9 is the 480V 3-phase, 3-pole 4-wire device. CS8269 is the 250V, 2-pole 3-wire device. Both are Leviton California Style (non-NEMA) locking receptacles rated 50A, industrial grade. Pick by the circuit you are landing on, not by the body style, because the blade patterns are not interchangeable between the two.
2) Is the Leviton CS816-9 suitable for a 480V 3-phase machine feed?
That is what it is for. The CS816-9 is rated 50A at 480V AC, 3-phase, wired 3-pole 4-wire, and Leviton lists it for heavy machinery, power distribution and panel circuits in plants and industrial facilities. If your machine is a 250V single-phase load instead, order the CS8269 (2-pole 3-wire).
3) Can I use an Eaton L14-20 locking receptacle in place of the Leviton CS8269?
No. The Leviton CS8269 is a California Style non-NEMA locking receptacle rated 50A, 250V, 2-pole 3-wire. The Eaton L14-20 is a NEMA L14-20 industrial locking receptacle in black nylon, which is a different, non-interchangeable blade pattern and a lower-amperage configuration. A cord cap wired for CS816-9 or CS8269 will not mate with an L14-20 device, and the reverse is equally true. Choose the Eaton L14-20 only if the existing plugs on the equipment are NEMA L14-20; use the Leviton California Style device when the equipment cordset is already California Style.
4) Is this a flush mount or a flanged receptacle?
Flush mount. The Leviton California Style locking receptacle sets into panels, enclosures and equipment surfaces with a low-profile face. If you need a flanged inlet-style body that mounts proud on a box or machine skin, that is a different device - the Bryant 71020ER 7 Series flanged locking receptacle is a flanged option we carry.
5) Is this Leviton locking receptacle rated for plant floor duty or is it just a commercial device?
It carries Leviton's industrial grade rating, with an impact-resistant black housing built for plant floors, machine rooms and jobsite handling. The locking connection resists vibration-induced disconnects under load. By comparison, the Eaton 7540 and Eaton L14-20 locking receptacles we stock are listed at commercial grade.
6) I need a 20A locking receptacle, not 50A. What else do you carry?
Both Leviton California Style devices here are 50A, so neither will suit a 20A branch circuit. For 20A twist-lock, look at the Eaton L14-20 industrial locking receptacle in black nylon (NEMA L14-20, 4-wire 125/250V pattern) or, for a 15A single-pole circuit, the Eaton NEMA L1-15 locking receptacle.
7) Do I need a matching plug, and does it have to be the same California Style configuration?
Yes, the mating plug or connector has to match the same California Style configuration and amperage, and it is sold separately. For the CS816-9 that means a 50A 480V 3-phase 3-pole 4-wire California Style plug; for the CS8269, a 50A 250V 2-pole 3-wire. Mixing configurations across the two will not mate.
8) What is the difference between the Leviton CS816-9 and an Eaton NEMA L1-15 locking receptacle?
They serve opposite ends of the load range. The Leviton CS816-9 is a 50A, 480V 3-phase, 3-pole 4-wire California Style locking receptacle built for heavy machinery and power-distribution circuits. The Eaton NEMA L1-15 locking receptacle is a 15A NEMA twist-lock device listed at commercial grade. Use the Eaton L1-15 for light single-phase locking connections such as equipment cords and appliances; use the Leviton CS816-9 where a 480V 3-phase feeder terminates.
9) I need a flanged locking receptacle for a machine enclosure, not a flush device. What should I look at?
The Leviton California Style receptacle is a flush-mount device intended to sit in a panel or enclosure opening. If the application calls for a flanged inlet-style body that mounts on the outside of equipment, the Bryant 71020ER is a 7 Series flanged locking receptacle. Confirm the Bryant configuration matches your cord cap before ordering, since the Leviton California Style pattern and NEMA twist-lock patterns do not intermate.
10) Why use a locking receptacle instead of a straight-blade device on machinery?
A locking connection twists into place and holds, so vibration from a motor or a tugged cord will not walk the plug out mid-run. On a 50A, 480V 3-phase feed that matters - an accidental disconnect under load is an arcing event, not just downtime. That is the case for the Leviton California Style locking receptacle over a straight-blade outlet on equipment circuits.
