The Pass & Seymour PS20AC4LA is an Industrial Extra Heavy Duty Specification Grade toggle switch finished in Light Almond, built for demanding commercial and industrial wiring applications. It features external screw-pressure-plate back and side wiring that accepts #14 - #10 AWG copper or copper-clad conductors, a heavy-gauge one-piece copper alloy contact arm, and a standard grounding terminal. Backed by cULus, CSA, UL, and Federal Spec listings, this switch delivers specification-grade durability and code-compliant performance where reliability is non-negotiable.

Pass & Seymour PS20AC4 – Frequently Asked Questions

1) What wire sizes will the Pass & Seymour PS20AC4 toggle switch accept?
The PS20AC4 takes #14 through #10 AWG copper or copper-clad conductors on external screw-pressure-plate terminals, and it is both back and side wired. That gives you the choice of straight-in back wiring for speed or side screws where you are pigtailing in a crowded box.
2) Do I need a separate ground pigtail with the PS20AC4, or does it self-ground?
The strap is nickel-plated steel with an integral ground and an auto-ground clip, so it grounds through the mounting screw into a properly grounded metal box. A standard grounding terminal is also on the device, so you can land a green wire directly when the box is nonmetallic or when your spec requires a bonded conductor.
3) Is the PS20AC4 acceptable on a job that calls for specification grade wiring devices?
Yes. It is an extra heavy-duty Specification Grade device, and it carries cULus, CSA, UL, and Federal Spec listings. That combination is what most institutional and government submittals ask for on a toggle switch, so it will clear a spec that rules out residential grade devices.
4) Can a Bussmann TPHCS-250 be used in place of the PS20AC4?
No. The Bussmann TPHCS-250 is a TPH Series high-current switch rated 80 Vdc with 100kA SCCR - a DC power switching component, not a wall-box wiring device. The Pass & Seymour PS20AC4 is an AC toggle switch with back and side screw-pressure-plate terminals for #14 - #10 AWG conductors that mounts in a standard device box. They are not interchangeable.
5) What is a comparable 20A AC toggle switch to the Pass & Seymour PS20AC4 from another brand?
The Bryant 4801GLI is a 4-Series 20A 277V lighted AC switch, which keeps the same 20A AC switching duty as the Pass & Seymour PS20AC4 specification grade toggle switch while adding an illuminated toggle. The PS20AC4 uses a heavy-gauge one-piece copper alloy contact arm with oversized silver alloy contacts and external screw-pressure-plate back and side wiring for #14 - #10 AWG copper conductors; the Bryant is the choice when you want the handle to light.
6) I need a switch that can be locked in position instead of a standard toggle - what should I use?
The Bryant 4802L is a 4 Series single-pole locking AC switch rated 20A 277V. The Pass & Seymour PS20AC4 is a standard specification grade toggle with no locking handle provision, so for equipment or circuits that must be secured against casual switching, the 4802L covers that at the same 20A duty.
7) Will this Pass & Seymour spec grade switch fit in a shallow or crowded outlet box?
It is built on a low-profile body specifically for tight boxes, and the device measures 3.281 in high by 1.32 in wide by 1.073 in deep. The shallow depth is the number that matters when you are stuffing #10 conductors back into an old work box.
8) Why choose an extra heavy-duty switch over a standard commercial toggle for high-cycle areas?
The difference is in the contact system. This one uses a heavy-gauge one-piece copper alloy contact arm that cuts contact bounce, oversized silver alloy contacts for longer life and better heat dissipation, and a cam that gives fast make and positive break to limit arcing. In a corridor, restroom, or shop area getting switched dozens of times a day, that is the construction that keeps it out of the callback list.
9) What other brands of commercial AC toggle switch could I use instead of the Pass & Seymour PS20AC4?
Bryant is the main cross-brand option we carry. The Bryant 4802L in the 4 Series is a single-pole locking AC switch rated 20A 277V, useful where you need the toggle keyed or locked off. The Bryant 4801GLI in the same 4-Series is a lighted 20A 277V AC switch if you want the handle to glow in a dark corridor. For a 15A device instead, the Bryant 9801 in the BR Series is a 1-pole 15A 120/277V AC switch.
10) Is there a lighter-duty alternative if a 20A specification grade switch is more than the circuit needs?
The Bryant 9801 is a BR Series 1-pole 15A 120/277V AC switch, a 15A device for lighter general-purpose branch circuits. The Pass & Seymour PS20AC4 is built for heavy-duty, high-cycle commercial and industrial switching with a glass-reinforced nylon back body and nickel-plated steel strap with integral ground and auto-ground clip, so it stays the pick where the spec calls for 20A extra heavy-duty.
11) How durable is the body and toggle on this Pass & Seymour switch?
The toggle is high-strength thermoplastic polycarbonate and the back body is glass-reinforced nylon. A locking support resists the face and back body pulling apart, which is the usual failure point when a device gets levered on during trim-out. Bumper pads inside keep the throw quiet.
12) What is the difference between the PS20AC4 and the Bryant CSB2BW?
The Bryant CSB2BW is a DPA Series 1/277V wiring device switch. The Pass & Seymour PS20AC4 is an extra heavy-duty specification grade toggle offered in Brown, Gray, and Light Almond with a matte finish, and its cULus, CSA, UL, and Federal Spec listings are what specifiers usually cite on commercial drawings.
13) Where is the Pass & Seymour PS20AC4 made?
Mexico. That matters on public jobs with country-of-origin reporting requirements, so note it before you submit.
