Pass & Seymour 28W7 Series Watertight Locking Plug, Yellow

The Pass & Seymour 28W7 Series Watertight Locking Plug is a heavy-duty, 30A locking device plug built for demanding industrial and outdoor power connections. This page covers the 28W7 Series across its available NEMA locking configurations, from NEMA L14-30 (125/250V) to NEMA L15-30 (250V 3-Phase), so you can select the configuration that matches your power distribution requirements. Every configuration in the 28W7 family shares the same rugged Yellow-finish TPV housing and multipoint sealing system, delivering NEMA 4, 4X, 6, 6P, and IP67 environmental protection for washdown, wet, and corrosive-environment applications where standard connectors fail.

Key Features

  • Electrical Rating: 30A locking device plug, available in NEMA L14-30 (125/250V) and NEMA L15-30 (250V 3-Phase) configurations for secure, code-compliant power connections.
  • Multipoint Sealing System: Provides environmental protection rated NEMA 4, 4X, 6, 6P, and IP67 for reliable performance in wet or washdown areas.
  • Durable Construction: Thermoplastic elastomer (TPV) body stands up to impacts, oils, chemicals, heat, and weather exposure.
  • Color-Coded Sealing Bushings: Included to accommodate a large range of cord diameters for a proper environmental seal.

Pass & Seymour 28W74 – Frequently Asked Questions

1) What's the difference between the 28W74 and 28W75 watertight locking plugs?
Both are 30A Pass & Seymour 28W7 Series watertight locking plugs, and the difference is the NEMA configuration. Model 28W74 is NEMA L14-30, 125/250V, which is the 4-wire single-phase configuration used for generator and portable power feeds. Model 28W75 is NEMA L15-30, 250V 3-phase. The blade patterns are not interchangeable, so the plug has to match the receptacle or inlet already on the equipment.
2) Can a Pass & Seymour 28W7 locking plug be hosed down during washdown?
Yes. The 28W7 Series plug is built with a multipoint sealing system rated NEMA 4, 4X, 6, 6P and IP67, and the body resists high-pressure hose down up to 1,500 psi. That covers sanitation washdown in food processing, wet outdoor use, and corrosive locations. The housing is thermoplastic elastomer (TPV), which stands up to oils, chemicals, heat and impact.
3) Do I need a separate bushing for my cord size with the 28W7 plug?
No separate purchase is needed. Color-coded sealing bushings are included with the 28W7 Series plug and cover a range of cord diameters so you get a proper environmental seal. Pick the bushing that matches your cord OD at install; using an oversized one will compromise the IP67 seal.
4) Is a watertight locking plug worth it over a standard industrial locking plug outdoors?
If the connection sits in standing water, gets hosed, or lives in a corrosive atmosphere, yes. Standard industrial-grade locking plugs such as the Leviton NEMA L6-20P or Leviton NEMA L16-30P are industrial grade but we hold no environmental rating on them, while the Pass & Seymour 28W7 carries NEMA 4X/6P and IP67 with nickel-plated blades and contacts for corrosion resistance. For a dry indoor panel feed, the plain industrial plug is the simpler buy.
5) I need a 50A locking plug, not 30A. What else do you carry?
The Pass & Seymour 28W7 Series is a 30A device, so it won't serve a 50A circuit. For higher capacity, the Eaton industrial armored locking plug is rated 50A 600V/250Vdc with back-wiring, in extra heavy duty construction.
6) Is a Leviton 2411 four-wire locking plug a substitute for the 28W74?
They are not interchangeable. The 28W74 is the NEMA L14-30 configuration of the 28W7 Series, rated 30A at 125/250V. The Leviton 2411 is a four-wire industrial grade locking plug rated 20A at 125/250V 3-phase, so both the amperage and the blade pattern differ from the 28W74.
7) The 28W7 is more plug than I need for a dry indoor 20A circuit. What is a simpler option?
The 28W7 Series is a 30A watertight device with a TPV body and multipoint sealing rated NEMA 4, 4X, 6, 6P and IP67 for washdown and corrosive areas. If the location is dry and the circuit is 20A at 250V, the Leviton 2321 is an industrial grade locking plug in NEMA L6-20P. For 20A at 120/208V, the Eaton 7411-C Safety Grip plug is a heavy-duty specification grade device.
8) Does a non-metallic locking plug like the Bryant 71020NP give the same wet-location protection as the 28W7?
Non-metallic housing and watertight sealing are different things. The Bryant 71020NP is a 7 Series non-metallic locking plug. The 28W7 Series uses a thermoplastic elastomer body with a multipoint sealing system and color-coded sealing bushings, carrying NEMA 4, 4X, 6, 6P and IP67 ratings plus resistance to 1,500 psi hose-down, which is what qualifies it for washdown and submersion-prone areas.
9) Does the yellow 28W7 locking plug come in other colors?
The 28W7 Series watertight locking plug is yellow only. The high-visibility yellow TPV housing is the same across both the L14-30 and L15-30 configurations, which helps when you want cord ends easy to spot on a jobsite or plant floor.
10) How are Pass & Seymour 28W7 watertight locking plugs packaged for stocking?
The 28W7 Series plugs are packaged 10 each, which suits MRO shelf stock or a crew kitting multiple cord ends. They are made in the United States.
11) Is the 28W7 plug easy to pull apart with gloves or wet hands?
Grip was designed for it. Large ribs are molded into the TPV body of the 28W7 plug to improve purchase when mating and unmating, which matters in washdown areas and outdoors where hands and the device are wet.
