Pass & Seymour PS20AC3 – Frequently Asked Questions

1) Will the Pass & Seymour PS20AC3 fit in a standard shallow wall box?
The PS20AC3 is built on a shallow body to make it easier to get into standard boxes and leave room to fold conductors back. Body depth is 1.073 inches, with overall height of 3.281 inches and width of 1.32 inches, so it drops into a normal single-gang strap opening without a deep box.
2) Does the PS20AC3 switch ground itself to a metal box, or do I still need a ground wire?
An auto-ground clip is built into the strap, so when the switch is mounted to a properly grounded metal box the yoke bonds through the mounting screw. In a nonmetallic box, or wherever your inspector wants it, land the equipment grounding conductor on the green screw as usual. The auto-ground is a backup path, not a reason to skip the ground conductor.
3) I need a three-way switch instead of the Pass & Seymour PS20AC3 - what should I order?
The PS20AC3 is a single-pole industrial extra heavy duty toggle. For three-way switching, where two switches control one load from separate locations, use the Eaton Arrow Hart AH-1223GY, an industrial grade three-way toggle switch rated 20A at 120/277V. A single-pole device cannot be wired into a three-way circuit, so the substitution has to be made at the device, not at the wiring.
4) What is the closest equivalent to the Pass & Seymour PS20AC3 toggle switch from another manufacturer?
The Leviton 1221 is the nearest cross-brand match. It is an extra heavy-duty industrial specification grade SPST toggle switch rated 20A at 120/277V, which puts it in the same extra heavy duty specification grade class as the PS20AC3. The PS20AC3 is supplied in brown thermoplastic with a matte finish, so if you are matching existing white or ivory devices on a wall you will need to confirm color separately when cross-shopping.
5) Is the PS20AC3 rated for a hospital or lab where the walls get chemically cleaned?
Yes, that is the environment it was built for. The back body is glass-reinforced, chemical-resistant thermoplastic, and the toggle and cover are chemical and impact resistant, so quat and bleach wipe-downs won't craze the housing. It is cULus listed and Federal Spec compliant, which is usually what an institutional spec calls for on a switch.
6) What is the difference between a spec grade switch like the PS20AC3 and a standard residential toggle?
Spec grade means the internals change, not just the label. The PS20AC3 uses oversized silver-alloy contacts for heat dissipation and long contact life, plus a one-piece heavy-duty brass alloy contact arm that virtually eliminates contact bounce. Residential grade switches use lighter contacts and a thinner strap. On a corridor, shop floor, or any switch cycled dozens of times a day, the spec grade device is what holds up.
7) What is the closest alternative to the PS20AC3 from another brand?
Leviton's extra heavy-duty spec grade single-pole toggles are the nearest cross-brand equivalents: the 1221 SPST at 20A 120/277V, and the 1221-2KL 1-pole at 20A 120/277V. Both are catalogued as specification grade like the Pass & Seymour. Color is the main thing to check, since the PS20AC3 is brown and the Leviton part numbers carry their own color suffixes.
8) I want a switch that shows when the load is on. Does the PS20AC3 have a pilot light?
No, the PS20AC3 is a plain industrial toggle with no indicator. If you need to see from the hallway that a fan or exterior light is running, go with a pilot light toggle instead: Leviton's industrial grade pilot light toggle in 1-pole 120V, or the 120/277V AC 20A 1-pole industrial pilot light version.
9) Does the PS20AC3 meet Federal Spec requirements for a government job?
Federal Spec compliant and cULus listed, which is the pair of callouts most government and municipal switch specs are written around. It is a specification grade industrial device, so it belongs on a submittal for federal, municipal, or institutional work rather than a residential-grade substitution.
10) Is there a version of a heavy duty toggle switch with a pilot light, like the PS20AC3 but lit?
The PS20AC3 has no pilot light - it is a plain industrial extra heavy duty toggle. If you want the handle or lens to indicate that the load is energized, the Leviton 1221-2L is an industrial grade pilot light toggle switch, 1-pole, 120/277V AC, 20A. For a 120V-only circuit, the Leviton 1201PLC is an industrial grade 1-pole pilot light toggle at 120V. Pilot devices typically need a neutral in the box, so verify the box has one before switching over.
11) What is the difference between the Pass & Seymour PS20AC3 and the Leviton 1221-2KL?
Both are extra heavy-duty specification grade 1-pole toggle switches. The Leviton 1221-2KL is rated 20A at 120/277V and carries the same spec grade classification as the Leviton 1221. The PS20AC3 differentiates on construction details: a glass-reinforced chemical-resistant thermoplastic back body, oversized silver-alloy contacts, a one-piece brass alloy contact arm, and an auto-ground clip that makes the grounding connection to the metal box through the mounting strap. It is cULus listed and Federal Spec compliant, and it is finished in brown.
12) Can I use the Bryant 4801W in place of the Pass & Seymour PS20AC3?
Only if the circuit suits it. The Bryant 4801W is a 4-Series single-pole toggle rated 15A at 277V AC in white, so it is a lower-ampacity device than a 20A switch and is not a like-for-like drop-in on a 20A branch circuit or where a 20A device is called out on the drawing. Where the load and the specification allow 15A, it is a single-pole toggle in the same wiring position as the PS20AC3, but in white rather than the PS20AC3's brown matte finish.
13) For standardizing switches across a facility, which of these covers the most openings alongside the PS20AC3?
A common approach is to keep the PS20AC3 as the single-pole extra heavy duty workhorse - glass-reinforced chemical-resistant thermoplastic body, cULus listed and Federal Spec compliant, suitable for industrial, healthcare, educational and government facilities - and stock the Eaton Arrow Hart AH-1223GY industrial grade three-way, 20A 120/277V, for the corridor and stair locations that need two-point control, plus the Leviton 1221-2L industrial grade pilot light toggle, 20A 120/277V 1-pole, for mechanical rooms and remote loads where staff need to see that a circuit is live. All three sit at 20A, which keeps the branch circuit device rating consistent.
14) Will the brown color of the PS20AC3 match the other devices in my building?
The PS20AC3 is brown with a matte finish, which is the traditional commercial and older-construction device color rather than the ivory or white you see on newer work. Matte hides fingerprints better than gloss. If your existing devices are white or ivory, this one will not match, and a brown wall plate is what you want with it.
