Pass & Seymour PS20AC3-W – Frequently Asked Questions

1) What wire sizes will the Pass & Seymour PS20AC3W toggle switch accept, and can I back-wire it?
The PS20AC3W takes #14 through #10 AWG copper or copper-clad wire. You can land conductors on the side screws or use the external screw-pressure-plate back wire connection, so #10 branch circuit wire is no problem. Aluminum wire is not called out, so stick with copper or copper-clad.
2) Will the PS20AC3W fit in a shallow or crowded switch box?
It is built with a shallow back body specifically to ease installation in tight boxes, and the locking support resists face-to-back body separation when you are pushing it into a crowded box. The device body measures 4.195 in high, 1.25 in wide and 1.09 in deep.
3) Is the Pass & Seymour PS20AC3W approved for federal and government facility work?
Yes. It is cULus Listed and Federal Spec Listed, which is why it gets specified on government and institutional jobs where the submittal has to show a listed specification-grade device.
4) What is the closest equivalent to the Pass & Seymour PS20AC3W from another manufacturer?
The Leviton 1221 is the nearest match. Both are extra heavy-duty specification grade single-pole toggle switches; the Leviton 1221 is rated 20A at 120/277V and is catalogued at Specification grade, the same grade designation carried by the PS20AC3W. The Pass & Seymour unit is white with a matte finish, cULus Listed, and accepts #14 to #10 AWG copper or copper-clad wire at side or back-wire screw-pressure-plate terminals. If you want the same spec-grade switch with a locking toggle, the Leviton 1221-2KL is an extra heavy-duty spec grade 1-pole switch rated 20A, 120/277V.
5) I need a three-way switch instead of a single-pole for a stairwell - what should I order?
The Pass & Seymour PS20AC3W is a single-pole toggle switch, so it will not do three-way travelers. For a three-way opening, the Eaton Arrow Hart industrial grade three-way toggle switch is rated 20A at 120/277V, and the Bryant 4903W is a 3-way AC toggle switch rated 20A 277V at commercial grade. Both cover the same 20A switching leg you would be running to a single-pole spec switch.
6) Do I need a separate grounding pigtail with this switch, or does it self-ground?
The switch has a standard grounding terminal with a screw-pressure plate back wire plus an auto-ground clip that makes positive ground through the mounting strap to a grounded metal box. In a metal box the clip handles it; in a nonmetallic box, land your equipment ground on the green terminal.
7) Why pay for an extra heavy duty spec grade switch instead of a commercial grade toggle?
The difference is in the guts. The PS20AC3W uses a one-piece nickel-plated brass strap for corrosion resistance, a one-piece brass alloy contact arm that virtually eliminates contact bounce, oversized silver-alloy contacts for longer contact life and heat dissipation, and a glass-reinforced thermoplastic back body that stands up to harsh cleaners. That matters on high-cycle openings, wash-down areas and industrial plants. For a light-traffic office or tenant space, a commercial grade device like the Bryant 4903W three-way is the lighter-duty option.
8) Will this switch hold up to harsh cleaning chemicals in a hospital or food plant?
It is built for it. The cover is impact- and chemical-resistant, the back body is glass-reinforced chemical-resistant thermoplastic, and the one-piece toggle is molded from chemical-, impact- and heat-resistant thermoplastic. The nickel-plated brass strap adds corrosion resistance in damp or wash-down areas.
9) Is there a version of this switch with a pilot light so housekeeping can see it is on?
The Pass & Seymour PS20AC3W has a plain one-piece thermoplastic toggle with no indicator. For an illuminated switch, the Leviton 1221-2L is an industrial grade pilot light toggle switch, 1-pole, rated 20A at 120/277V AC, and the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V. Both keep the single-pole function of the PS20AC3W while adding the indicator.
10) Can I use a 15 amp commercial switch in place of the PS20AC3W?
They are not the same switching capacity. The Bryant 4801W is a single-pole 15A 277V AC toggle switch, so it sits below the 20A spec-grade class the PS20AC3W belongs to and should only go on a circuit sized for 15A. The Pass & Seymour PS20AC3W is Specification Grade, cULus Listed, and also Federal Spec Listed, which matters if the drawing calls for a federal-spec device on a government or institutional job.
11) Will an Ideal 774005 heavy-duty toggle switch work as a substitute for the PS20AC3W?
No - they are different kinds of device. The Ideal Industries 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, built for equipment and panel wiring rather than a wall box. The Pass & Seymour PS20AC3W is a single-pole wall-mount switch with side and external screw-pressure-plate back wire terminals for #14 to #10 AWG copper or copper-clad wire, plus a grounding terminal and auto-ground clip, so it lands in a standard device box behind a wall plate.
12) Will the white finish on the PS20AC3W match other white devices and plates on my floor?
The device is white with a matte finish, not gloss. If the receptacles and wall plates already in the building are gloss white, the toggle will read slightly flatter next to them. For a facility standardizing on one look, order the switches, receptacles and plates in the same color family and finish.
13) Does the PS20AC3W come with a wall plate?
No plate is included. The PS20AC3W is the switch only, so order a toggle-style wall plate separately, single-gang or ganged to match the box, in the color you are standardizing on.
14) Where is the Pass & Seymour PS20AC3W made, and what do I order it by?
Order it as Pass & Seymour part number PS20AC3-W, the white industrial extra heavy duty specification grade toggle switch. Country of origin is Mexico, which is the detail Buy American or trade-compliance paperwork usually asks for.
