Pass & Seymour L1620P 20A NEMA L1620 Twist-Lock Plug, Black/White Nylon

The Pass & Seymour L1620P is a 20A NEMA L1620 twist-lock plug built with a black back and white front nylon 6 body for durability on demanding job sites. This industrial-grade plug pairs brass alloy blades and connector contacts with a rounded back contour that reduces snags and hang-ups during handling. It is cULus Listed, making it a dependable choice for professional power connections requiring code-compliant twist-lock hardware.

Key Features

  • NEMA Configuration: Rated 20A, NEMA L1620 twist-lock configuration with visible stamped configuration and device rating for quick identification.
  • Durable Construction: Impact- and corrosion-resistant nylon 6 shell material with a black back and white front body stands up to job-site conditions.
  • Brass Alloy Contacts: Industrial-strength brass alloy plug blades and connector contacts resist heat rise and provide excellent conductivity.
  • Snag-Resistant Design: Rounded back contour reduces snags and hang-ups when the cord is handled or dragged on the job site.
  • Sealed Cord Grommet: Integral flexible rubber cord grommet conforms to and seals around SO cord, protecting the wiring chamber from oils, water, or chips.
  • Cord Retention: Double dovetail design provides superior protection against cord pull-out forces, while new-design external cord grips give visible assurance of safe, proper cord retention.
  • Grip & Assembly: Scallop shell design and raised ribs provide a non-slip gripping surface for insertion, withdrawal, and turning, and quick-thread assembly and cord-grip screws come backed-out, ready-to-wire.

Pass & Seymour L1620-P – Frequently Asked Questions

1) What should I use instead of the Pass & Seymour L1620P if the receptacle has straight blades rather than a twist-lock slot?
The L1620P is a NEMA L1620 twist-lock plug, so it will not engage a straight-blade outlet. For a straight-blade opening, the Leviton 5666-C is a 3-wire 2-pole polarized industrial grade straight blade plug rated 250-volt 1-phase, and the Eaton Arrow Hart AH5266 Ultra Grip is a straight blade plug rated 15A 125V in an industrial specification grade. Match the plug configuration to the outlet pattern, not just the amperage.
2) Will this twist-lock plug hold up on SO cord dragged around a job site?
That is what the body is built for. An integral flexible rubber cord grommet conforms to and seals around SO cord, keeping oils, water and chips out of the wiring chamber, and a double dovetail cord grip resists pull-out. The nylon 6 shell is impact and corrosion resistant, and the back is contoured round so the plug is less likely to snag when the cord is dragged.
3) Can I wire the L1620P without extra parts or hardware?
It ships ready to wire. The quick-thread assembly screws and the cord-grip screws come backed out, so you strip the SO cord, land the conductors and close it up. No separate clamp or boot is needed for cord retention, and the external cord grips give you a visual check that the cord is properly gripped.
4) What is the difference between this twist-lock plug and a straight blade plug like the Leviton 5666-C?
The L1620P locks: you insert and turn, and the blades cam into the receptacle so vibration or a cord pull will not drop the connection, which is why it is used on job-site and outdoor equipment feeds. A straight blade device such as the Leviton 5666-C, a 3-wire 2-pole industrial grade plug for 250V single phase, simply pulls straight out and is a different voltage and pole arrangement entirely. Pick the locking pattern wherever accidental disconnection matters, or where the receptacle is already L16-20.
5) I need a plug that can be dragged through wet areas - how does the L1620P compare to a watertight plug?
The L1620P uses an integral flexible rubber cord grommet that seals around SO cord to keep oils, water, and chips out of the wiring chamber, in a nylon 6 body. If the application calls for a fully watertight assembly, the Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration. Note the configurations differ, so the receptacle on the circuit decides which one fits.
6) Is there a right-angle alternative to the Pass & Seymour L1620P for tight clearance behind equipment?
The L1620P is a straight-body twist-lock plug measuring 2.57 in long by 2.2 in wide. For openings where the cord has to turn immediately, the Leviton 275-E is a commercial grade 4-wire 3-pole straight blade angle plug and the Bryant 8395T is an angle hospital-grade plug in NEMA 5-20P. Both are angle bodies in straight-blade configurations rather than twist-lock, so verify the receptacle pattern first.
7) We buy plugs in bulk for a facility standardization program - which of these comes in a case quantity?
The Pass & Seymour L1620P is sold as an individual industrial twist-lock plug. If the requirement is a bulk carton of one configuration, the Leviton 8215-CAT is a tamper-resistant hospital-grade NEMA 5-15P plug in a pack of 100 and the Leviton 8315-CT is a tamper-resistant hospital-grade NEMA 5-20P plug in a pack of 100. Those are straight-blade hospital grade devices, so they standardize general receptacle circuits rather than twist-lock equipment drops.
8) Is a commercial grade plug like the Leviton 275-E a direct substitute for the Pass & Seymour L1620P?
No. The L1620P is a twist-lock plug with brass alloy blades, a double dovetail cord retention design, and a nylon 6 shell, while the Leviton 275-E is a commercial grade 4-wire 3-pole straight blade angle plug. The blade pattern and pole count differ, so the 275-E will not land in an L1620 receptacle. Closer in duty class are the industrial grade straight-blade devices such as the Leviton 5666-C or the Eaton Arrow Hart AH5266, though those are also straight blade.
9) How big is this plug, and will it fit in a tight equipment enclosure or strain relief boot?
Body dimensions are 2.57 in long by 2.2 in wide, so it is a full industrial-size cord cap rather than a slim straight-blade plug. Check clearance if you are landing it inside a panel knockout area or behind a machine guard.
10) Will the L1620P work in a wet or washdown location?
The rubber grommet seals around the cord and keeps water, oils and chips out of the wiring chamber, and the nylon 6 shell is corrosion resistant, which suits outdoor job-site equipment wiring. It is not a watertight-rated device, though. If you need a watertight assembly, a device built for it, such as the Bryant 8666TSP watertight plug in NEMA 6-15P, is the right category, bearing in mind that is a different configuration and rating.
11) Is there a spec sheet for the Pass & Seymour L1620-P?
Yes. The manufacturer spec sheet for MPN L1620-P is published by Legrand and linked from the product's specification data, which is the document to submit when a job requires manufacturer cut sheets.
