Pass & Seymour PS20AC2-W Extra Heavy-Duty 2-Pole Toggle Switch, 20A 120/277V

The Pass & Seymour PS20AC2-W is an extra heavy-duty specification grade 2-pole toggle switch built for demanding commercial and industrial wiring applications, rated 20A at 120/277V. This back- and side-wired switch is available in Light Almond and White, letting installers match the device to the surrounding decor without changing any of the underlying electrical specifications. It features a nickel-plated steel strap with integral ground and auto-ground clip for a positive ground connection, plus a heavy-gauge one-piece copper alloy contact arm that virtually eliminates contact bounce. This device is cULus Listed for code-compliant installation in professional electrical systems.

Key Features

  • Rating: 20A, 120/277V 2-pole toggle switch suited for extra heavy-duty specification grade use.
  • Wiring: External screw-pressure-plate back- and side-wire terminals accept #14 - #10 AWG copper or copper-clad conductors.
  • Durable Construction: Nickel-plated steel strap with integral ground and auto-ground clip assures a positive ground; back body is made of glass-reinforced nylon for added strength.
  • Contact Design: Heavy-gauge one-piece copper alloy contact arm virtually eliminates contact bounce, and oversized silver alloy contacts provide long life and better heat dissipation.
  • Switching Action: Cam controls a fast "make" and positive "break" to minimize arcing.
  • Toggle: High-strength thermoplastic polycarbonate toggle with heavy-duty bumper pads for quiet operation.
  • Design: Shallow design eases installation, and locking support resists face and back body separation.
  • Grounding: Grounding terminal is standard on every switch.
  • Color Options: Available in Light Almond and White to suit a range of commercial and industrial finish schemes.

Pass & Seymour PS20AC2-W – Frequently Asked Questions

1) What wire size do the terminals on the PS20AC2 accept, and can I back-wire it?
External screw-pressure-plate terminals take #14 through #10 AWG copper or copper-clad conductors, and the device is both back- and side-wired, so you can land conductors straight in behind the plate or wrap the screws. #12 pulls for a 20A branch circuit land without any trouble.
2) What is the closest equivalent to the Pass & Seymour PS20AC2 if I need a single-pole switch instead of 2-pole?
The PS20AC2 is a 2-pole switch rated 20A at 120/277V. For a single-pole opening at the same electrical rating, the Leviton 1221-2KL is an extra heavy-duty specification grade 1-pole toggle switch rated 20A, 120/277V. The Leviton 1221 is also offered as an SPST extra heavy-duty industrial specification grade switch at 20A 120/277V. Both switch one hot leg only, so they will not break both legs of a 240V or two-circuit load the way the 2-pole PS20AC2 does.
3) I need three-way switching rather than 2-pole - what should I order instead of the PS20AC2?
A 2-pole switch like the PS20AC2 breaks two circuit legs from one location; it does not provide multi-location control. For three-way control at the same 20A, 120/277V rating, the Eaton Arrow Hart AH-1223GY is an industrial grade three-way toggle switch rated 20A, 120/277V. The Bryant 4903W is a 3-way AC toggle switch rated 20A 277V in commercial grade. Three-way devices use a common and two travelers, so the wiring differs from the 2-pole layout.
4) The Ideal 774005 is also a double-pole switch - can I use it in place of the PS20AC2?
They are not interchangeable in a standard wall box. The Ideal Industries 774005 is a heavy-duty DPST on-off toggle switch with spade terminals, which suits panel or enclosure mounting with crimped connections. The Pass & Seymour PS20AC2 is a wall-mount specification grade device with external screw-pressure-plate back- and side-wire terminals accepting #14 to #10 AWG copper, a nickel-plated steel strap with integral ground and auto-ground clip, and a cULus Listing. If you are wiring a device box with building wire, the PS20AC2 is the one that lands on a strap and yoke.
5) Does this 2-pole switch need a separate ground wire pigtail in a metal box?
A grounding terminal is standard on every PS20AC2, and the nickel-plated steel strap has an integral ground plus an auto-ground clip, so the yoke bonds to a grounded metal box through the mounting screw. You can still run a bonding jumper to the green screw, which is what you will need in a nonmetallic box.
6) Is the PS20AC2 toggle switch approved for commercial code inspection?
It is cULus Listed, which covers both US and Canadian installations. Pass & Seymour builds it as extra heavy-duty specification grade, the tier normally called for on commercial and institutional drawings rather than residential grade.
7) Will this switch fit a shallow or crowded existing box?
The PS20AC2 uses a shallow body design to ease installation in tight boxes, and a locking support keeps the face from separating from the back body during a hard push into wire bundles. The back body is glass-reinforced nylon.
8) What colors does the PS20AC2 2-pole switch come in, and are the electrical specs the same?
Two colors: White (PS20AC2-W) and Light Almond (PS20AC2-LA). Only the color changes. Both are the same 20A 120/277V 2-pole device with a matte finish, so you can mix colors across a building to match existing plates without touching the spec.
9) Can I use this switch to control a 277V ballast or LED driver circuit on a commercial lighting panel?
Yes. The 120/277V AC rating at 20A covers 277V lighting branch circuits, and being 2-pole it will break both conductors where the design calls for that. For a single-pole 277V spec grade equivalent, the Leviton 1221-2KL is a 1-pole extra heavy-duty device at 20A 120/277V.
10) Is there a version of this switch with a pilot light to show when the load is on?
The Pass & Seymour PS20AC2 is a 2-pole switch with a polycarbonate toggle and no indicator. If you need visual confirmation at the switch, the Leviton 1221-2L is an industrial grade pilot light toggle switch, 120/277V AC, 20A, 1-pole, and the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V. Both are single-pole, so they control one leg rather than the two legs the PS20AC2 breaks.
11) How does the Pass & Seymour PS20AC2 compare to the Bryant 4801W for a 277V lighting circuit?
The Bryant 4801W is a 4-Series single-pole AC toggle switch rated 15A at 277V, white. The Pass & Seymour PS20AC2 is a 2-pole device rated 20A at 120/277V with oversized silver alloy contacts and a one-piece copper alloy contact arm, offered in Light Almond and White. If the circuit is a 20A branch and you need to break both legs, the PS20AC2 matches; for a 15A single-pole 277V leg, the 4801W is the single-pole device.
12) If I am standardizing a facility on specification grade switches, which devices sit in the same class as the PS20AC2?
The Pass & Seymour PS20AC2 is an extra heavy-duty specification grade device, 20A 120/277V, cULus Listed, with a glass-reinforced nylon back body and nickel-plated steel strap. In the same class, the Leviton 1221 is an extra heavy-duty industrial specification grade SPST switch at 20A 120/277V and the Leviton 1221-2KL is an extra heavy-duty spec grade 1-pole at 20A 120/277V; both are listed at specification grade. Commercial and industrial grade alternatives such as the Bryant 4903W and the Eaton Arrow Hart AH-1223GY sit at a different grade designation.
13) Will this hold up on a high-cycle switch location like a shop or corridor light?
That is what it is built for. A heavy-gauge one-piece copper alloy contact arm cuts contact bounce, oversized silver alloy contacts handle the heat and extend life, and a cam gives a fast make and positive break to limit arcing. The toggle is high-strength thermoplastic polycarbonate with bumper pads so it stays quiet after heavy use.
14) How is the PS20AC2 packaged for a job-site order?
It ships 10 each per pack, which suits stocking a panel of openings or a renovation punch list rather than buying singles. Country of origin is Mexico.
