Pass & Seymour L2120P 20A NEMA L2120 Locking Plug, Black/White Body

The Pass & Seymour L2120P is a 20A NEMA L2120 locking plug featuring a black back and white front body constructed from impact- and corrosion-resistant durable nylon 6 shell material. Built for demanding job-site use, this plug pairs industrial-strength brass alloy blades with a rounded, snag-resistant contour and an integral flexible rubber cord grommet that conforms to and seals around SO cord to protect the wiring chamber from oils, water, or chips. The L2120P is cULus Listed and Federal Spec Listed, making it a reliable choice for professional electrical installations.

Key Features

  • 20A NEMA Rating: Visible stamped NEMA L2120 configuration and device rating for quick field identification.
  • Durable Construction: Impact- and corrosion-resistant nylon 6 shell in a black back, white front body.
  • Locking Design: Raised ribs provide a non-slip gripping profile for turning to lock and unlock.
  • Brass Alloy Contacts: Industrial-strength brass alloy plug blades and connector contacts resist heat rise and provide excellent conductivity.
  • Cord Protection: Integral flexible rubber cord grommet conforms to and seals around SO cord to protect the wiring chamber from oils, water, or chips.
  • Cord Pull-Out Resistance: Double dovetail design provides superior protection against cord pull-out forces.
  • Job-Site Ready: Rounded back contour reduces snags and hang-ups, while quick-thread assembly and cord-grip screws come backed-out, ready-to-wire.

Pass & Seymour L2120-P – Frequently Asked Questions

1) Will this locking plug hold up on a jobsite cord that gets dragged through oil and coolant?
That is what it was built for. The shell is nylon 6, specified impact and corrosion resistant, and an integral flexible rubber grommet seals around SO cord to keep oils, water, and chips out of the wiring chamber. A double dovetail design resists cord pull-out, and the rounded back contour cuts down on snagging when the cord is pulled across equipment.
2) Is the L2120P UL listed for commercial and industrial installations?
It carries a cULus Listing, which covers both US and Canadian requirements, and it is also Federal Spec Listed, which is what institutional and government procurement typically asks for on a wiring device.
3) Can I use the L2120P on patient care equipment in a hospital?
No. Hospital grade is a separate listing on the plug itself, and the L2120P is specified as an industrial and commercial locking plug, not hospital grade. For patient care cord sets ZenSupply carries hospital grade options such as the Bryant 8266T (NEMA 5-15P), the Bryant 8395T angle plug (NEMA 5-20P), the watertight Bryant 8666TSP (6-15P), and the tamper-resistant Leviton 8215-CAT (5-15P) and 8315-CT (5-20P).
4) Is the Leviton 275-E angle plug a substitute for the Pass & Seymour L2120P?
No. The Pass & Seymour L2120P is a NEMA L2120 locking plug rated 20A, where the blades twist into the mating connector to lock. The Leviton 275-E is a commercial grade 4-wire 3-pole straight blade angle plug, so its blades pull straight out and will not mate with an L2120 locking receptacle or connector. Use the L2120P wherever the opening calls for a twist-lock L2120 configuration.
5) What should I use instead of the L2120P for a 125V 15A cord on hospital equipment?
The Pass & Seymour L2120P is a NEMA L2120 locking plug and is not a hospital grade device. For a 15A 125V hospital application, the Bryant 8266T is a hospital grade plug in the NEMA 5-15P configuration, and the Leviton 8215-CAT is a tamper-resistant hospital-grade plug, also NEMA 5-15P, supplied in a pack of 100 for standardizing across a facility.
6) Is the Pass & Seymour L2120P rated 20 amps?
Yes, 20A. That rating is stamped on the plug along with the NEMA L2120 configuration, and the brass alloy blades and contacts are specified to resist heat rise at that load.
7) What cord type should I use with the Pass & Seymour L2120P plug?
The grommet is specified to conform to and seal around SO cord, so SO (and the equivalent SOOW type portable cord) is what the cord grip is designed around. Cord-grip and assembly screws ship backed out ready to wire, and the external cord grips let you see the cord is properly retained after assembly.
8) I need a straight blade plug, not a twist-lock. What else is there?
The L2120P is a locking device and will not work in a straight blade outlet. For straight blade industrial work, ZenSupply carries the Leviton 5666-C, a 3-wire 2-pole polarized industrial grade straight blade plug rated 250V single phase, and the Eaton Arrow Hart Ultra Grip, a 15A 125V industrial specification grade straight blade plug. For a 4-wire 3-pole straight blade in an angle body there is the Leviton 275-E, commercial grade.
9) What is the correct part number to order for the Pass & Seymour L2120 locking plug?
Order it as Pass & Seymour L2120-P. It is the plug half of the L2120 pairing; the matching connector is a separate part. Country of origin is Mexico.
10) For a wet or washdown location, how does the L2120P compare to a watertight plug?
The Pass & Seymour L2120P uses a nylon 6 shell with an integral flexible rubber cord grommet that seals around SO cord to keep oils, water, and chips out of the wiring chamber, and it is cULus Listed. If the application calls for a device built specifically as watertight, the Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration, which is a different blade pattern and amperage class than the L2120 twist-lock.
11) How big is the L2120P plug body?
Published dimensions are 2.57 in length by 2.2 in width. Worth checking if you are plugging into a recessed or ganged locking receptacle where body diameter decides whether adjacent devices clear.
12) Is this plug easy to identify once it is installed in a panel of similar devices?
The body is two-tone, black back with a white front, and the NEMA L2120 configuration plus the device rating are stamped visibly on the plug. Raised ribs on the shell also give a non-slip grip for twisting it in and out, which is the detail that matters when a crew is cycling cord sets with gloves on.
