Pass & Seymour PS420P9-W – Frequently Asked Questions

1) Will the Pass & Seymour PS-420P9W pin and sleeve plug mate with other brands of IEC 309 connectors?
The Pass & Seymour watertight pin and sleeve plug is built to IEC 309 and Legrand states guaranteed IEC 309 compatibility across its Pin & Sleeve line. That means mating is governed by the IEC 309 configuration, so the amperage, voltage band and pole/wire count on the mating connector or receptacle have to match: 3-pole, 4-wire at 250V, with the same Motor FLA rating you order (20A, 30A, 60A or 100A). Mixing amperage ratings or pole counts will not mate.
2) Can this pin and sleeve plug be used outdoors or in a washdown area?
Yes. Sealing is done in two places: natural-rubber grommets seal the cable entry where the cord passes in, and an integral neoprene gasket on the locking ring seals the joint once the plug is mated to its connector or receptacle. The nylon housing is impact and corrosion resistant and the pins are nickel-plated brass, which is why these get used for construction temp power, marine and wet-location equipment hookups. Note the watertight seal at the mating face only exists when the plug is actually mated and the ring is locked down.
3) I need a watertight plug for hospital equipment. Is this the right one?
No, not if the application calls for a hospital grade device. The Pass & Seymour pin and sleeve is an IEC 309 industrial watertight plug and carries no hospital grade designation. For hospital grade work ZenSupply carries the Bryant 8666TSP watertight hospital grade plug in N6-15P, plus the Bryant 8266T in NEMA 5-15P and the Bryant 8395T angle plug in NEMA 5-20P, and the tamper-resistant Leviton 8215-CAT (5-15P) and 8315-CT (5-20P).
4) What is the difference between the Pass & Seymour PS-420P9W pin and sleeve plug and a straight blade plug like the Leviton 275-E?
They mate differently and are not interchangeable. The Pass & Seymour PS-420P9W is a pin and sleeve device built to IEC 309, so its round pins and sleeves engage a matching IEC 309 connector or receptacle and the locking ring's neoprene gasket seals the mated joint. The Leviton 275-E is a commercial grade straight blade angle plug, which uses flat blades in a NEMA pattern. Both are 3-pole 4-wire, so they can serve the same circuit configuration, but a pin and sleeve plug will only land in a pin and sleeve device and a straight blade plug will only land in a NEMA receptacle.
5) Can a watertight hospital-grade plug such as the Bryant 8666TSP be used in place of the Pass & Seymour PS-420P9W outdoors?
No. Both are watertight devices, but they serve different circuits. The Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration, a 15A two-pole straight blade pattern for patient-care and similar branch circuits. The Pass & Seymour PS-420P9W is a 3-pole 4-wire 250V IEC 309 pin and sleeve plug offered in Motor FLA ratings of 20A, 30A, 60A and 100A, with a nylon housing, nickel-plated brass pins and natural-rubber cable grommets. A feeder or motor circuit wired for the pin and sleeve device cannot terminate in an N6-15P plug.
6) Is a pin and sleeve plug the right choice, or should I use a NEMA straight blade or twist-lock plug?
Pin and sleeve is the choice when the connection lives outdoors, gets hosed down, or carries higher current than a blade device sensibly handles. The Pass & Seymour watertight IEC 309 plug covers 3-pole 4-wire 250V up to 100A Motor FLA with a sealed, locking-ring mating joint. If the load is a standard 125V receptacle circuit indoors, a straight blade device is simpler and far cheaper to match: ZenSupply carries the Leviton 275-E 4-wire 3-pole commercial straight blade angle plug and the Leviton 5666-C 3-wire 2-pole industrial grade 250V plug for that kind of work. The tradeoff is that blade devices will not mate with IEC 309 equipment and do not give you the watertight seal.
7) Does a 3-pole 4-wire pin and sleeve plug mean three phases plus ground?
Yes, that is the usual reading of it: three current-carrying poles plus an equipment ground, rated 250V. There is no neutral in this configuration, so if your equipment needs a neutral as well as a ground you need a 4-pole 5-wire device instead, not this one.
8) Is the Pass & Seymour pin and sleeve watertight plug UL listed for commercial jobs?
It is cULus Listed, so it carries both the US and Canadian marks on the same device, which matters if you are specifying one part number across facilities on either side of the border.
9) For a 250V single-phase portable load, is there a simpler plug than the Pass & Seymour pin and sleeve?
Yes, if the load does not need a fourth wire or a watertight mated connection. The Pass & Seymour PS-420P9W family is a 3-pole 4-wire 250V pin and sleeve plug rated to IEC 309, covering Motor FLA ratings from 20A to 100A. For a two-pole single-phase 250V circuit, the Leviton 5666-C is a 3-wire 2-pole polarized industrial grade straight blade plug rated 250 volt, 1-phase, which is a lighter-duty straight blade device rather than a sealed pin and sleeve assembly.
10) Is the Eaton Arrow Hart AH5266 an alternative to the Pass & Seymour PS-420P9W for industrial cord sets?
Only for a much smaller load on a different circuit. The Eaton Arrow Hart AH5266 Ultra Grip is an industrial specification grade straight blade plug rated 15A 125V. The Pass & Seymour PS-420P9W is a 3-pole 4-wire 250V pin and sleeve plug with guaranteed IEC 309 compatibility and cULus Listing, offered from 20A through 100A Motor FLA. If the cord set feeds 250V three-pole equipment or has to seal at the mated joint, the pin and sleeve device is the one that matches; the AH5266 suits 125V single-phase tools and cords.
11) How much assembly is involved in wiring this plug in the field?
Very little prep. It ships cable-ready: the cord grip arrives open, the terminal screws are already backed out, and the front and back body do not need to be taken apart before you wire it. The cord grip is a hinged design and the terminal screws are combination head, so you can drive them with either a flat or Phillips driver.
12) How are these pin and sleeve plugs packaged, and where are they made?
Packaging is 10 each, which is worth knowing if you only need one or two for a single hookup. Country of origin is the United States, which can matter on government and institutional work with domestic sourcing requirements.
13) Why nickel-plated brass pins instead of plain brass on an industrial plug?
The nickel plating adds corrosion resistance at the contact surfaces without giving up conductivity, which is the point on a device that gets used outdoors, on marine work, or in washdown areas where plain brass would oxidize and start running warm at the contacts.
14) If a facility is standardizing on tamper-resistant hospital-grade plugs, where does the Pass & Seymour pin and sleeve plug fit?
They cover separate parts of the building. Tamper-resistant hospital-grade devices such as the Leviton 8215-CAT in NEMA 5-15P and the Leviton 8315-CT in NEMA 5-20P handle 125V patient-care and general-use cord ends. The Pass & Seymour PS-420P9W handles the heavy end: a gray nylon 3-pole 4-wire 250V IEC 309 pin and sleeve plug in Motor FLA ratings of 20A, 30A, 60A and 100A, with watertight sealing at the cable entry and the locking ring for wet-location, motor and portable equipment feeds. A facility typically specifies both rather than choosing between them.
15) Does any angle-body plug substitute for the Pass & Seymour PS-420P9W where cord strain is a concern?
Angle-body straight blade plugs such as the Bryant 8395T, an angle hospital-grade plug in the NEMA 5-20P configuration, and the Leviton 275-E, a 3-pole 4-wire commercial grade straight blade angle plug, direct the cord away from the face but use blade contacts and will not mate with an IEC 309 device. The Pass & Seymour PS-420P9W addresses cord strain its own way, with a hinged cord grip that ships open and cable-ready plus natural-rubber grommets sealing the cable entry, while keeping the IEC 309 pin and sleeve interface.
16) What color is the Pass & Seymour watertight pin and sleeve plug, and will it match the rest of my pin and sleeve devices?
Gray body. On IEC 309 devices the color on the housing is cosmetic, but the sleeve and pin arrangement is what fixes which voltage band it mates with, so match the configuration and amperage rather than the housing color when you are standardizing a facility.
