Pass & Seymour CS20AC1-I – Frequently Asked Questions

1) What wire size does the Pass & Seymour CS20AC1I toggle switch accept?
The CS20AC1I takes #14 through #10 AWG copper or copper-clad wire. Connections are side wire or external screw-pressure-plate, so you can land a stripped conductor under the screw or use the pressure plate where you are pulling #10 and want a cleaner termination. No back-wire push-in holes.
2) Will this Pass & Seymour switch fit in a standard single-gang box with a standard wall plate?
Yes. The CS20AC1I is a standard strap-mounted toggle switch measuring 3.281 x 1.32 x 1.073 inches, which is the normal single-gang device footprint, and it mounts with the included tri-drive mounting screws. Use a standard toggle-opening wall plate; in Ivory if you want the plate to match the device.
3) Is this switch approved for federal and institutional projects?
The CS20AC1I is cULus Listed and Federal Spec Listed, which is what most government, healthcare and education specs call for on a spec-grade switching device. That Federal Specification compliance is usually the line item that decides whether a switch can go on a public-works job.
4) Which switch should I use if I need the toggle to be key or lock controlled rather than open to the public?
The Pass & Seymour CS20AC1I is a standard commercial specification grade toggle with an exposed polycarbonate handle, so anyone can operate it. Where tenants or the public should not be able to switch a circuit, look at the Leviton 1221-2IL, an industrial grade locking toggle switch, SPST single-pole, 20A 120/277V, or the Bryant 4802L, a 4 Series single-pole locking AC switch rated 20A 277V. Both restrict operation at the device itself instead of relying on a locked cover plate.
5) What is the closest equivalent to the Pass & Seymour CS20AC1I single-pole spec grade toggle switch from another brand?
The Leviton 1221-2W is the nearest match in function and rating: it is an extra heavy-duty industrial specification grade SPST single-pole toggle switch rated 20A at 120/277V AC. The Pass & Seymour CS20AC1I is a commercial specification grade toggle built with a one-piece brass alloy contact arm, oversized silver alloy contacts, and a glass-reinforced nylon back body, and it ships in Ivory. The Leviton is catalogued in White, so if you are matching existing Ivory devices down a corridor, the color is the deciding difference.
6) I need a three-way switch instead of a single-pole spec grade toggle - what should I order?
The Pass & Seymour CS20AC1I is a single-pole specification grade toggle. For a two-location circuit, the Leviton 1223-PLR is a 3-way extra heavy-duty industrial grade toggle switch with a pilot light, rated 20 amp at 120 volt. The pilot light gives you a lit indication of circuit status, which matters in stairwells and back-of-house runs where the load is out of sight.
7) What looks like a substitute for the CS20AC1I but will not work in the same box?
Two to watch. The Eaton 275VBOX is a decorator duplex combination switch with auto-ground, 15A, in White - it is a two-switch decorator-style device, not a single toggle, so it needs a decorator plate and a different wall plate opening than the CS20AC1I. The Leviton 1286-W is a 20-amp DPDT center-off toggle, specification grade; it looks like an ordinary toggle but is a double-pole double-throw device with a center-off position, intended for reversing or two-source switching rather than simple single-pole on/off.
8) For a federal or government facility spec, which of these switches carries the right listings?
The Pass & Seymour CS20AC1I is cULus Listed and Federal Specification listed, which is typically what a government or institutional submittal calls for on a specification grade wiring device. Among the comparable toggles, the Leviton 1221-2W and 1286-W are catalogued as specification grade and the Leviton 1221-2IL as industrial grade. If the submittal names Federal Specification compliance specifically, the CS20AC1I states it directly.
9) Do I need a separate ground wire pigtail for this switch?
The CS20AC1I has a one-piece steel strap with an integral ground, plated for corrosion resistance, so the grounding means is built into the device. You still bond it per code at the box.
10) What is the difference between a specification grade switch like this and a residential grade switch?
Spec grade means the internals are built for repeated commercial switching rather than occasional household use. On the CS20AC1I that is a one-piece brass alloy contact arm, oversized silver alloy contacts, a glass-reinforced nylon back body with locking support against face-to-body separation, and a polycarbonate toggle that resists chipping under abuse. The cam gives a fast make and positive break to cut arcing. For a corridor, restroom, or retail space being cycled dozens of times a day, that is the grade to buy.
11) Will the Ivory finish match the other devices on my floor?
The CS20AC1I is Ivory with a matte finish, so it blends with the older ivory and almond device families rather than with bright white. If your building standard is white, this is the wrong color to order for a visible wall; pick a white device instead.
12) What are the alternatives to the Pass & Seymour CS20AC1I if I need a different switch function?
Within the same spec-grade class ZenSupply carries the Leviton 1221-2W, an extra heavy-duty industrial spec grade SPST single-pole toggle rated 20A 120/277V, as the straight white equivalent. If the job needs three-way control with a pilot light, the Leviton 1223-PLR is a 3-way spec grade toggle with pilot light at 20A 120V. For a double-pole double-throw center-off application, such as a two-speed or two-source selector, the Leviton 1286-W is a 20A DPDT center-off spec grade switch. None of those are Ivory substitutes for color matching, but they cover the functions the CS20AC1I does not.
13) What do I use if the switch needs to be visible in a dark corridor?
The Pass & Seymour CS20AC1I has a plain matte-finish toggle with no illumination. If you need the handle located in the dark, the Bryant 4801GLI is a 4-Series lighted AC switch rated 20A 277V. Note the Bryant is a 277V device, so confirm your branch circuit voltage before swapping it in.
14) Is a 15A commercial switch an acceptable substitute for the Pass & Seymour CS20AC1I?
Only where the circuit and the spec allow it. The CS20AC1I is a specification grade toggle wired for #14 through #10 AWG copper or copper-clad conductors, which is consistent with 20A branch circuit work. The Bryant 9801 is a BR Series 1-pole 15A 120/277V AC switch - a lower ampere rating, so it is not a drop-in on a 20A circuit specified for a 20A device. Match the ampere rating on the drawing rather than the yoke size.
15) I manage a building with ivory devices throughout - which spec grade switches will match?
The Pass & Seymour CS20AC1I is Ivory with a matte finish, so it blends with existing ivory toggles and ivory wall plates. Among the comparable devices, the Leviton 1221-2W, Leviton 1286-W and Eaton 275VBOX are catalogued in White, which will read noticeably cooler next to ivory on the same wall. If color continuity across the fleet matters more than brand continuity, the CS20AC1I is the one that holds the match.
16) I want a switch with an indicator light so staff can see the circuit is energized. Is this it?
The CS20AC1I has no pilot or lighted toggle. For a visible indicator, the Bryant 4801GLI is a 4-Series lighted AC switch rated 20A 277V, and the Leviton 1223-PLR adds a pilot light on a 3-way spec grade switch.
17) Where is the Pass & Seymour CS20AC1I made, and what is the exact part number to order?
Order it as Pass & Seymour CS20AC1-I, the Ivory specification grade toggle switch. Country of origin is Mexico, which matters if you are filing country-of-origin documentation on a federally funded project.
18) Will this switch hold up in a high-traffic public restroom or school corridor?
That is the application it is built for. Heavy-duty toggle bumpers keep the action smooth and quiet through repeated use, the polycarbonate toggle resists breaking and chipping under abuse, and the back body locking support resists face-to-back-body separation, which is the usual failure point when a switch gets hit hard. Oversized silver alloy contacts extend switch life under frequent cycling.
