Pass & Seymour PS5366-X – Frequently Asked Questions

1) What amperage and voltage is the Pass & Seymour PS5366X plug rated for?
The PS5366X is a 20A, 125V plug. That covers standard single-phase 120V branch circuits on 20-amp cord sets, tool leads, and portable equipment. If your equipment runs on 250V, this is the wrong device for it.
2) How many wires does the PS5366X plug terminate, and how hard is it to wire?
It is a 3-wire device: hot, neutral, and ground. All three terminals sit on the same plane, so you can land conductors from any angle without rotating the body. It ships completely ready-to-wire, the cord grip is a rugged two-piece design for uniform retention, and the tri-drive assembly screws plus recessed cord-grip screws cut down on screwdriver slippage.
3) Is the Pass & Seymour PS5366X UL listed and acceptable for federal projects?
The PS5366X carries a cULus Listing, which covers both US and Canadian requirements, and it is Federal Spec Listed, so it meets the federal specification requirement that shows up on government and institutional jobs.
4) What should I use instead of the Pass & Seymour PS5366X in a patient care area where hospital-grade plugs are required?
The PS5366X is a spec-grade, extra-hard use plug rated 20A, 125V, so it is not a hospital-grade device. For a 20A 125V patient-care cord set, the Leviton 8315-CT is a tamper-resistant hospital-grade plug in the NEMA 5-20P configuration. If the equipment cord ends in a 15A configuration instead, the Leviton 8215-CAT is the tamper-resistant hospital-grade plug in NEMA 5-15P, and the Bryant 8266T is a hospital-grade NEMA 5-15P plug. Note that both Leviton tamper-resistant plugs are supplied in packs of 100.
5) Is the PS5366X suitable for extra-hard use cord on a job site?
That is what it is built for. The PS5366X is a spec-grade, extra-hard use plug with a nylon housing for impact and chemical resistance, brass alloy blades and contacts that resist heat rise, and an internal dust shield that keeps the terminals clean in dirty environments. It is used on industrial and commercial power wiring, tool cord sets, and renovation work.
6) What is the difference between the PS5366X and the Leviton 275-E plug?
The PS5366X is a 3-wire, 20A 125V spec-grade plug with a nylon housing and a straight body. The Leviton 275-E is a commercial grade 4-wire, 3-pole straight blade plug in an angle body. The 4-wire 3-pole configuration serves a different circuit arrangement than the 3-wire PS5366X, and the angle body routes the cord parallel to the wall rather than straight out.
7) Can the PS5366X be used in a wet or washdown location?
The PS5366X is built for extra-hard use cord applications with a nylon housing and an internal dust shield that keeps terminals free of contaminants, but it is not described as a watertight device. Where a watertight plug is called for, the Bryant 8666TSP is a watertight hospital-grade plug in the N6-15P configuration - note that it is a different blade configuration and voltage class than the 125V PS5366X.
8) What is the exact part number and finish to order for the Pass & Seymour extra-hard use 20A plug?
Order Pass & Seymour PS5366X, manufacturer part number PS5366-X. It comes in black and white, and it is made in Mexico. There is one configuration, so no separate finish or option code to specify.
9) Will a nylon plug hold up better than rubber in a shop environment?
The PS5366X uses a nylon housing, which gives it impact and chemical resistance for solvent and oil exposure in industrial settings. A rubber-bodied plug such as the Bryant 7516NC in the NM10-50P series is a different approach, flexible and built around a higher-amperage range configuration. For 20A 125V cord sets in a shop, the nylon spec-grade body with the internal dust shield is the one that keeps contaminants off the terminals.
10) If I am standardizing on industrial grade plugs across a facility, how does the PS5366X compare to Leviton and Eaton industrial plugs?
The PS5366X is a spec-grade, cULus listed plug with a nylon housing, brass alloy blades and contacts, and a two-piece cord grip, rated 20A 125V. On the industrial side, the Eaton Arrow Hart Ultra Grip is an industrial specification grade straight blade plug at 15A 125V, and the Leviton 5666-C is an industrial grade 3-wire 2-pole plug at 250V 1-phase. Choosing among them comes down to the amperage and voltage of the circuit each cord set serves.
