Cooper Wiring Devices CWL-515C Two-Pole Three-Wire Locking Receptacle, 15A

The Cooper Wiring Devices CWL-515C Locking Receptacle is engineered for secure, dependable power connections in demanding industrial environments. This two-pole, three-wire locking receptacle is rated 15A and is available in 125 volt and 277 volt configurations, giving specifiers flexibility to match the receptacle to the circuit voltage at hand. It accepts cords with diameters ranging from 0.38 to 1 in, making it well suited for industrial equipment and machinery that require a connection resistant to accidental disconnection. Electricians and maintenance teams specify locking receptacles like this one specifically because standard straight-blade devices can loosen or pull free under vibration, movement, or tension, and a twist-lock connection keeps the circuit intact. Built to Cooper Wiring Devices' standards for industrial-duty electrical products, this receptacle delivers the twist-lock security professionals expect on demanding job sites, in plants, and on production floors where downtime from a disconnected cord is not an option.

Key Features

Cooper Wiring Devices CWL715R – Frequently Asked Questions

1) What voltage options does the Cooper CWL515C locking receptacle come in?
Two voltage builds are offered on this Cooper two-pole three-wire locking receptacle: the CWL515C at 125 volts and the CWL715R at 277 volts. Both are 15A. Pick by the circuit you are landing on, not by the body, since the blade patterns differ between a 125V and a 277V device and a plug made for one will not twist into the other.
2) Will this Cooper locking receptacle work with my SO cord on a shop machine?
It takes cord diameters from 0.38 to 1 inch, which covers most industrial cordsets and extension assemblies. Measure the outside jacket diameter of your cord. Under 0.38 inch and the clamp will not grip the jacket properly; over 1 inch and it will not seat.
3) I need a 20A or a 4-wire locking receptacle instead of a 15A two-pole. What else is available?
The Cooper CWL515C tops out at 15A on two poles and three wires. For a higher-amp or higher-pole job, ZenSupply carries the Leviton 2410 industrial grade flush mount NEMA L14-20R at 20A 125/250V, the Eaton L14-20 industrial locking receptacle in black nylon, and the Leviton 2450 industrial grade 4-pole 4-wire unit rated 20A at 277/480V Y. The Leviton 2450 is the one to look at if your load needs four wires rather than three.
4) What is the closest equivalent to the Cooper CWL515C locking receptacle if I need a 20A device instead of 15A?
The Cooper CWL515C is a two-pole, three-wire locking receptacle rated 15A. When the load calls for a 20A two-pole three-wire device, the Leviton 2420 industrial grade flush mount locking receptacle covers that step up, and the Leviton 2330 is another industrial grade flush mount locking receptacle in the same family. Both are industrial grade, matching the industrial application the Cooper device is specified for.
5) Which locking receptacle should I specify for a 277/480V three-phase circuit rather than the Cooper CWL515C?
The Cooper CWL515C is a two-pole, three-wire receptacle, which does not cover three-phase four-wire service. For 277/480V Y AC, the Leviton 2450 is an industrial grade four-wire, four-pole single locking receptacle rated 20A at that voltage. Note that the Cooper family does include a 277 volt two-pole three-wire version under MPN CWL715R, so confirm whether the circuit is single-phase 277 or a full 277/480V Y system before ordering.
6) What is the difference between the Cooper CWL515C and the Eaton 7540 locking receptacle?
The Cooper CWL515C is a two-pole, three-wire locking receptacle rated 15A for industrial applications. The Eaton 7540 is a NEMA L1-15 locking receptacle listed as commercial grade. L1-15 is a two-wire, non-grounding pattern, so it does not provide the dedicated ground path the three-wire Cooper device supports. If the connected equipment requires an equipment ground, the Eaton 7540 is not a drop-in alternative.
7) Why use a twist-lock receptacle instead of a standard straight-blade outlet on machinery?
Vibration and cord tension pull straight-blade plugs loose. A twist-lock connection like this 15A Cooper device holds the plug mechanically until it is rotated out, so equipment on a production floor or a piece of moving machinery stays powered. If the load never moves and the cord is not disturbed, a straight blade is simpler and cheaper.
8) Does this 15A locking receptacle give me a ground for my equipment?
Yes. It is a two-pole, three-wire configuration, so the third conductor is the equipment grounding path for the connected load. Two current-carrying poles plus ground. If your load needs a neutral in addition to two hots and a ground, you need a four-wire device instead.
9) What size opening does the Cooper CWL515C need in the plate or box?
The receptacle body measures 2 inches by 1.75 inches, so it fits a standard single-gang locking-device opening. Confirm your cover plate is cut for a locking receptacle and not a duplex, since the round twist-lock face will not sit in a duplex plate.
10) Is there a flanged or surface-mount locking receptacle if I am not putting it in a wall box?
This Cooper 15A device is a standard body for box mounting. For an inlet-style flanged application, the Bryant 71020ER 7 Series flanged locking receptacle is the alternative ZenSupply stocks. Flanged units mount to the face of an enclosure or machine panel rather than inside a gang box.
11) The Cooper CWL515C is a flush device. What do I use if the receptacle has to mount to a flanged outlet on a machine enclosure?
The Cooper CWL515C is a two-pole, three-wire 15A locking receptacle intended for standard device mounting. Where the connection has to land on the face of an equipment enclosure or a portable power box, the Bryant 71020ER is a 7 Series flanged locking receptacle, which mounts on a flange plate rather than in a conventional device box. Confirm the NEMA configuration of the flanged unit matches the cordset before ordering.
12) For a wash-down or chemical exposure area, is the Cooper CWL515C the right locking receptacle or is there a better option?
The Cooper CWL515C is built for industrial application and accepts cord diameters from 0.38 to 1 in, but if the mounting location sees impact or chemical contact, the Leviton 2330 and Leviton 2420 are industrial grade flush mount locking receptacles described as impact- and chemical-resistant. Both are 20A-class industrial devices, so verify the circuit rating and NEMA pattern match your load before substituting.
13) If I am standardizing locking receptacles across a plant, which of these are industrial grade versus commercial grade?
The Cooper CWL515C is specified for industrial application as a two-pole, three-wire 15A locking receptacle. Among the alternatives, the Leviton 2330, 2410, 2420 and 2450 are all listed as industrial grade, while the Eaton 7540 and the Eaton L14-20R are listed as commercial grade. If a facility standard calls for industrial grade throughout, the Leviton group gives you 20A single-phase, 125/250V L14-20R and 277/480V four-pole options under one grade.
14) Is a 15A locking receptacle like this rated for plant and shop-floor duty or just light commercial?
Cooper builds this one for industrial application, which is the use class stated for it. If you want a body specifically called out as impact and chemical resistant for a wash-down or chemical exposure area, the Leviton 2330 and Leviton 2420 flush-mount industrial grade units are the ones to compare against.
