Pass & Seymour PS20AC1-I – Frequently Asked Questions

1) What wire size does the Pass & Seymour PS20AC1I switch accept, and can I back-wire it?
The PS20AC1I takes #14 to #10 AWG copper or copper-clad wire. You can wire it from the side screws or through the external screw-pressure-plate back wiring, so stranded #12 pigtails in a crowded commercial box are no problem. There are no push-in quick-connect holes here; the pressure plate clamps the conductor under the screw.
2) Is a specification grade switch worth it over a residential grade switch for a high-traffic facility?
For corridors, restrooms, schools, and plant areas where a switch gets thrown dozens of times a day, yes. The PS20AC1I is built as Industrial Extra Heavy Duty Specification Grade: glass-reinforced chemical-resistant thermoplastic back body, a one-piece brass alloy contact arm that virtually eliminates contact bounce, and oversized silver-alloy contacts for long life and heat dissipation. A residential grade switch has none of that and is the part that comes back as a callback.
3) Does this Pass & Seymour switch meet Federal Specification requirements for government work?
The PS20AC1I is Federal Spec Listed and cULus Listed, which is what a government or institutional spec writer is usually looking for when they call out a specification grade switch. Those two listings are what we hold on record for this device.
4) What is the closest equivalent to the Pass & Seymour PS20AC1I from another manufacturer?
The Leviton 1221-2W is the nearest match in function and grade: it is an extra heavy-duty industrial specification grade SPST single-pole toggle switch rated 20A at 120/277V AC. The PS20AC1I is likewise an industrial extra heavy-duty specification grade toggle switch, with a glass-reinforced thermoplastic back body, one-piece brass alloy contact arm, and side plus external screw-pressure-plate back wiring for #14 to #10 AWG copper. The Leviton is cataloged in white, while the Pass & Seymour is ivory, so match the device color to the existing wall plates and adjacent devices before standardizing.
5) I need a three-way switch instead of a single-pole in the same heavy-duty grade. What should I order?
The PS20AC1I is a single-pole industrial extra heavy-duty specification grade toggle. For a three-way opening in comparable grade, the Leviton 1223-PLR is a 3-way extra heavy-duty industrial grade toggle switch rated 20 amp at 120 volt and includes a pilot light, which is useful where the controlled load is out of sight. Confirm the pilot light is acceptable on the circuit before specifying it as a straight swap for a plain 3-way.
6) We need the switch to be key or lock controlled so tenants cannot operate it. Is the PS20AC1I an option?
No - the PS20AC1I uses a one-piece thermoplastic toggle with no locking provision, so anyone can operate it. For restricted operation, the Leviton 1221-2IL is an industrial grade locking toggle switch, SPST single-pole, 20A at 120/277V, and the Bryant 4802L is a 4 Series single-pole locking AC switch rated 20A 277V. Note the Bryant is a 277V device, so verify the circuit voltage before ordering it for a 120V branch.
7) Does this Pass & Seymour spec grade toggle switch ground itself to a metal box?
Yes. The PS20AC1I has an auto-ground clip on the one-piece nickel-plated brass strap, so mounting it in a grounded metal box establishes the equipment ground through the mounting screw. It still has a green grounding terminal path via the strap, but in a nonmetallic box you need to bond the device conductor normally.
8) Will an ivory toggle switch match the other ivory devices and plates in my building?
The PS20AC1I is ivory with a matte finish, which is the standard ivory used across commercial wiring device lines, so it lines up with ivory receptacles and standard ivory toggle wall plates. Note that matte ivory reads slightly warmer than white or light almond, so don't mix it into a run of white devices on the same wall.
9) Will the PS20AC1I hold up in a kitchen or plant area that gets washed down with strong cleaners?
Chemical resistance is built into both halves of the device. The back body is glass-reinforced chemical-resistant thermoplastic and the toggle is molded from chemical-, impact-, and heat-resistant thermoplastic, with a nickel-plated brass strap for corrosion resistance. It is not a weatherproof or wet-location assembly on its own, so for washdown areas pair it with the appropriate gasketed cover or enclosure.
10) Will the PS20AC1I fit a standard single-gang box and a standard toggle wall plate?
Yes. It measures 3.281 in high, 1.32 in wide, and 1.073 in deep, which is the normal strap-mounted toggle footprint for a single-gang box and a standard single-toggle plate. The locking support between face and back body keeps the assembly from separating when you cinch it into a tight box.
11) What are my alternatives to the Pass & Seymour PS20AC1I if I need a different switch function?
If you need the same extra heavy-duty spec grade build in a different configuration, the Leviton 1221-2W is the single-pole specification grade equivalent, the Leviton 1223-PLR is a 3-way industrial grade switch with a pilot light, and the Leviton 1286-W is a DPDT center-off in specification grade. For a locking toggle that resists casual operation, look at the Leviton 1221-2IL industrial grade locking switch or the Bryant 4802L locking AC switch.
12) I need a switch with an indicator light so staff can see it is on from the hallway. Is this the right one?
No. The PS20AC1I is a plain ivory toggle with no pilot or indicator. For a lighted switch, go to the Bryant 4801GLI lighted AC switch or the Leviton 1223-PLR 3-way toggle with pilot light.
13) Is there a lighted version so the switch can be found in a dark mechanical room?
The PS20AC1I toggle is not illuminated. If the maintenance crew needs to locate the switch in the dark, the Bryant 4801GLI is a 4-Series 20A 277V lighted AC switch. The Bryant is a 277V device, so it suits 277V lighting branches rather than 120V general-purpose circuits. The PS20AC1I remains the choice where a plain extra heavy-duty specification grade toggle with auto-ground clip is what the drawing calls for.
14) Do I need a specification grade switch like the PS20AC1I, or will a commercial grade device do?
It depends on duty. The PS20AC1I is built to industrial extra heavy-duty specification grade with oversized silver-alloy contacts, a one-piece nickel-plated brass strap, and a glass-reinforced chemical-resistant back body, and it is cULus Listed and Federal Spec Listed - which is what you want in high-traffic facilities, federal work, and harsh-cleaner environments. Where the duty is lighter, the Eaton 275VBOX is a commercial grade decorator duplex combination switch with auto-ground, rated 15A in white. The Eaton is a 15A decorator-style combination device rather than a 20A single toggle, so it is not a visual or electrical match on a standardized toggle layout.
15) Do I need a switch and receptacle in one gang instead of a straight toggle?
Where box space is tight and you need both a switch and an outlet in one opening, the PS20AC1I will not do it, it is a toggle switch only. The Eaton decorator duplex combination switch with auto-ground is the commercial grade combination device for that situation.
16) Why does contact bounce matter when I am switching fluorescent or LED lighting loads?
Contact bounce arcs, and arcing is what erodes a switch's contacts and causes premature failure on inductive and electronic ballast loads. The PS20AC1I uses a heavy-duty one-piece brass alloy contact arm that virtually eliminates bounce, with oversized silver-alloy contacts for heat dissipation and heavy-duty bumpers for quiet, smooth operation. That combination is why it gets specified where lighting circuits are switched constantly.
17) We are replacing 15-amp switches throughout a building. Is the PS20AC1I an upgrade or should I stay at 15 amp?
The PS20AC1I is the heavier device - an industrial extra heavy-duty specification grade toggle with oversized silver-alloy contacts and back wiring for #14 to #10 AWG copper, so it accepts the larger conductors used on 20A branches. If the circuits are genuinely 15 amp and the duty is light, the Bryant 9801 is a BR Series 1-pole 15A 120/277V AC switch. Match the device rating to the branch circuit and the conductor size rather than assuming a direct one-for-one swap.
