Pass & Seymour CSB15AC4-I – Frequently Asked Questions

1) What wire size does the Pass & Seymour CSB15AC4 toggle switch accept?
The CSB15AC4 terminates #14 through #10 AWG copper or copper-clad wire. You can side wire it or use the external screw-pressure-plate back and side wire connections, so it works whether you're pigtailing in a crowded commercial box or landing #10 on a long homerun. Terminal and mounting screws are tri-drive.
2) Is the Pass & Seymour CSB15AC4 switch UL and CSA listed for commercial code work?
It carries UL, cULus, CSA, and Federal Spec listings. That combination covers US and Canadian commercial and industrial installations and satisfies jobs written to a federal specification, which is often what pushes a spec on a government or institutional project past standard-grade devices.
3) Can I swap a standard-grade toggle switch for the CSB15AC4 in an existing box?
Yes. It's a straight replacement for a standard-grade toggle in a standard device box, and upgrading standard-grade to spec-grade is one of its listed applications. The body measures 2.375 in high, 1.32 in wide, and 1.073 in deep, so it fits normal device openings and standard wall plates.
4) I need a 20A switch instead of the 15A Pass & Seymour CSB15AC4 - what should I use?
For a 20A circuit, the Bryant 4802L is a 4 Series single-pole locking AC switch rated 20A 277V, and the Bryant 4801GLI is a 4-Series 20A 277V lighted AC switch. The Pass & Seymour CSB15AC4 is a Hard Use Specification Grade toggle switch that terminates #14 to #10 AWG copper or copper-clad wire; if the branch circuit and load call for 20A, step to one of the Bryant 4 Series devices rather than the 15A toggle.
5) What is the closest alternative to the Pass & Seymour CSB15AC4 toggle switch if I need a 15A AC switch from another brand?
The Bryant 9801 is a BR Series 1-pole 15A 120/277V AC switch, which covers the same 15A single-pole toggle switching duty as the Pass & Seymour CSB15AC4 Hard Use Specification Grade toggle switch. The CSB15AC4 is a brown device with a glass-reinforced nylon back body, oversized silver alloy contacts, and a one-piece brass alloy contact arm, and it terminates #14 to #10 AWG copper or copper-clad wire at side wire or external screw-pressure-plate connections. Confirm the color and wallplate match your existing devices before ordering either one.
6) Will a brown spec grade toggle switch match the existing devices in my building?
The CSB15AC4 is brown with a matte finish, so it lines up with older brown device runs and brown wall plates already in the building. If your other openings are ivory, white, or gray, this one will stand out; match on color before standardizing a floor on it.
7) What makes the CSB15AC4 a hard use switch rather than a standard residential toggle?
Three things do the work. The back body is glass-reinforced nylon with locking support that resists face-to-back-body separation, the toggle is high-strength thermoplastic polycarbonate so it doesn't chip or snap under abuse, and the contacts are oversized silver alloy on a one-piece brass alloy contact arm. The cam gives a fast make with positive break to cut arcing. That's the difference in a corridor, stairwell, or plant floor switch that gets thrown hundreds of times a week.
8) Do I need a separate ground screw or pigtail with the Pass & Seymour CSB15AC4?
No separate grounding accessory is needed. The switch uses a one-piece steel strap with an integral ground, plated for corrosion resistance, so you bond straight to the strap. The plating matters in damp or washdown areas where a bare strap would rust behind the plate.
9) Is the CSB15AC4 the right switch for a high-current DC disconnect?
No. It's an AC wiring device for lighting and general switch control in commercial and industrial branch circuits. For high-current DC work you want something like the Bussmann TPHCS-250, a TPH Series high-current switch rated 80 Vdc with 100kA SCCR. Different class of device entirely.
10) Is there an alternative to the CSB15AC4 with a pilot light or a lock so occupants cannot switch it off?
Yes, but they are different device functions. The Bryant 4801GLI is a 4-Series lighted AC switch at 20A 277V, useful where you want a visible indicator at the toggle, and the Bryant 4802L is a 4 Series single-pole locking AC switch at 20A 277V for openings where the switch must be secured against casual operation. The Pass & Seymour CSB15AC4 is a standard brown toggle with no light or lock, built for hard-use commercial and industrial switching with a polycarbonate toggle and heavy-duty toggle bumpers for quiet action.
11) Will a Bussmann TPHCS-250 work as a substitute for the Pass & Seymour CSB15AC4?
No. The Bussmann TPHCS-250 is a TPH Series high-current switch rated 80 Vdc with a 100kA short-circuit current rating, a power-distribution component rather than a wall-box wiring device. The Pass & Seymour CSB15AC4 is a Hard Use Specification Grade AC toggle switch with side wire or external screw-pressure-plate terminations for #14 to #10 AWG copper or copper-clad wire and a one-piece steel strap with integral ground for standard box mounting. For a wall switch replacement, stay with a toggle device such as the Bryant 9801 BR Series 15A 120/277V AC switch.
12) Is the Pass & Seymour CSB15AC4 a quiet switch for offices and patient rooms?
It uses heavy-duty toggle bumpers for a smooth, quiet switching action, so it's a reasonable choice where snap noise is a complaint, such as offices, classrooms, and healthcare corridors. It's still a mechanical toggle, not a silent electronic device.
13) Where is the Pass & Seymour CSB15AC4 made, and what part number do I order?
Order by manufacturer part number CSB15AC4 from Pass & Seymour. Country of origin is Mexico, which matters if you're filling out country-of-origin documentation on a government or institutional submittal.
