Pass & Seymour CS20AC3-W – Frequently Asked Questions

1) What size wire does the Pass & Seymour CS20AC3W toggle switch accept?
The CS20AC3W is built to take #14 through #10 AWG copper or copper-clad wire. Pass & Seymour offers this spec grade switch in side wire form and in an external screw-pressure-plate version that takes both back and side wire, so you can pigtail or feed straight through depending on how the box is wired. Terminal and mounting screws are tri-drive, so a flat, Phillips, or square driver all work on them.
2) Will the Pass & Seymour CS20AC3W fit a standard single-gang wall box and cover plate?
Dimensionally the CS20AC3W measures 3.281 x 1.32 x 1.073 inches, which is standard toggle switch geometry for a single-gang box and a standard toggle-opening wall plate. The one-piece steel strap carries an integral ground, so the yoke grounds through the mounting screws to a grounded metal box.
3) What is a comparable commercial AC toggle switch to the Pass & Seymour CS20AC3W if I need a 20A 277V rating on the switch itself?
The Bryant 4801GLI is a 4-Series AC switch rated 20A 277V, so it covers the same commercial 277V lighting-circuit duty in a toggle-style device. The difference is that the 4801GLI is a lighted switch, meaning the toggle carries an illuminated indicator, while the Pass & Seymour CS20AC3W is a plain commercial specification grade toggle in white with a matte finish. Choose the CS20AC3W where you want an unlit toggle that matches other white devices in the room, and the 4801GLI where crews need to locate the switch in a dark space.
4) I need to keep users from turning a lighting circuit off at the wall. What should I use instead of the Pass & Seymour CS20AC3W?
Use the Bryant 4802L instead. It is a 4 Series single-pole locking AC switch rated 20A 277V, so the toggle can be locked in position on a circuit you do not want switched by occupants. The Pass & Seymour CS20AC3W is a standard commercial specification grade toggle with a high strength thermoplastic polycarbonate toggle and no locking provision, so it is the right part for normal room lighting control and the wrong part where the switch has to be secured.
5) What is the difference between a spec grade switch like the Pass & Seymour CS20AC3W and a residential grade toggle?
Spec grade construction is what separates them. The CS20AC3W uses a one-piece steel strap plated against corrosion, a glass-reinforced nylon back body with locking support that resists the face separating from the body, a one-piece brass alloy contact arm, and oversized silver alloy contacts. The cam makes fast and breaks positively to hold down arcing, and heavy-duty toggle bumpers keep the action quiet. Residential grade devices are generally lighter duty in all of those areas. For high-cycle openings like a corridor, break room, or classroom, the spec grade device is the one that holds up.
6) Is the toggle on this Pass & Seymour switch strong enough for a high-abuse area?
The toggle is high strength thermoplastic polycarbonate, chosen to resist breaking and chipping under heavy abuse, and the back body is glass-reinforced nylon with locking support so the face and back body do not pull apart. That combination is what you want in a gym, corridor, school, or public restroom where the switch gets hit hard.
7) What are the alternatives to the Pass & Seymour CS20AC3W if I need a lighted or locking AC switch?
If the CS20AC3W's plain toggle is not what the job calls for, Bryant covers a couple of the common variations. The Bryant 4801GLI is a lighted 4-Series 20A 277V AC switch, useful when the fixture it controls is out of sight. The Bryant 4802L is a single-pole locking AC switch at 20A 277V, for circuits you do not want switched off by the wrong person. Bryant also lists the 9801 in its BR Series as a 1-pole 15A 120/277V AC switch if you are on a 15 amp circuit.
8) Do I need a separate ground screw or pigtail when installing the CS20AC3W?
No separate grounding accessory is needed. The steel strap is one piece with an integral ground and is plated for corrosion resistance, so bonding follows the strap. In damp or corrosive environments that plating is the reason the yoke does not rust out behind the plate.
9) Is there a lighter-duty alternative to the Pass & Seymour CS20AC3W for a 15A branch circuit?
Yes. The Bryant 9801 is a BR Series 1-pole AC switch rated 15A at 120/277V, which suits a 15A lighting branch where a 20A device is more than the circuit calls for. The Pass & Seymour CS20AC3W is the commercial specification grade choice, built with a one-piece steel strap with integral ground, glass-reinforced nylon back body, and oversized silver alloy contacts for long switch life in heavier-traffic commercial spaces.
10) Can I use a Bussmann TPHCS-250 in place of the Pass & Seymour CS20AC3W?
No. The Bussmann TPHCS-250 is a TPH Series high-current switch rated 80 Vdc with 100kA SCCR, which is a DC power switching device for equipment and distribution duty, not a wall-box device. The Pass & Seymour CS20AC3W is a commercial specification grade AC toggle switch in white that mounts in a standard device box with tri-drive terminal and mounting screws and accepts #14 to #10 AWG copper or copper-clad wire. The two are not interchangeable in either direction.
11) Will the white finish on the CS20AC3W match the other devices in my building?
The toggle is white with a matte finish, not gloss. Matte is what most current commercial spec grade device lines use, so it sits well next to other spec grade white devices. If your existing switches are an older glossy white, expect a slight sheen difference rather than a color difference.
12) Where do I find the full electrical ratings for the Pass & Seymour CS20AC3W?
Pass & Seymour publishes a spec sheet PDF for the CS20AC3W that carries the complete electrical data, and it is linked with the product record. The catalog number to quote when ordering or cross-referencing is CS20AC3-W.
13) How does the Bryant CSB2BW compare with the Pass & Seymour CS20AC3W for a 277V commercial switching job?
The Bryant CSB2BW is a DPA Series wiring device switch listed at 1/277V, so it addresses the same 277V commercial switching application. The Pass & Seymour CS20AC3W approaches it as a specification grade toggle with a one-piece brass alloy contact arm and a cam designed for fast make with positive break action to limit arcing, and it is cULus Listed. If your submittal calls out a white matte toggle to match the rest of the devices on the floor, the CS20AC3W is the one to specify.
