Leviton 1223-2W – Frequently Asked Questions
1) Can the Leviton 1223-2W switch be used on a 277V lighting circuit?
Yes. The Leviton 1223-2W toggle switch is rated 120/277V AC at 20 amps, so it works on standard 120V commercial branch circuits and on 277V fluorescent or LED lighting circuits fed from a 480/277V system. That dual rating is why it gets specified in warehouses and office buildings where both voltages are present.
2) How many switches do I need for 3-way control of a hallway light?
Two. A 3-way switch like the Leviton 1223-2W controls one load from two separate locations, so you install a pair of them, one at each end, with a 3-wire traveler run between them. One 3-way switch on its own will not work as a simple on/off replacement for a single-pole device.
3) Can I use the Leviton 1223-2W to replace a single-pole switch?
Not as a drop-in. A single-pole switch has two load terminals; the 1223-2W is a 3-way device with a common and two travelers, and it needs that third conductor in the box to function as intended. If you only have a 2-wire switch loop, use a single-pole 20A spec grade device instead. Bryant's 4801W is a single-pole toggle switch option in white if that is the configuration you actually need.
4) What is the closest cross-brand equivalent to the Leviton 1223-2W 20A 3-way toggle switch?
The Eaton Arrow Hart industrial grade three-way toggle switch, AH-1223GY, matches it most directly: it is a three-way toggle rated 20A at 120/277V, the same amperage and dual-voltage rating the Leviton 1223-2W carries. The Leviton is specification grade in white; the Eaton is an Arrow Hart series device in gray, so if device color has to match the rest of the devices in the opening, that is the detail to confirm before you swap.
5) Can I use the Bryant 4801W in place of the Leviton 1223-2W?
No. The Bryant 4801W is a 4-Series single-pole switch rated 15A at 277V AC, so it switches a load from one location only and will not wire into a three-way circuit. The Leviton 1223-2W is a 20A three-way device, which controls one load from two switch locations. Use the 4801W only where the opening is genuinely single-pole and 15A is adequate.
6) Is a spec grade switch worth it over a residential grade one for a commercial building?
For high-cycle openings it is the difference that matters. The Leviton 1223-2W is built to Extra Heavy-Duty Industrial/Specification Grade, which is the construction class electrical contractors use where a switch gets thrown dozens of times a day, such as stairwells, corridors and shop floors. Residential grade devices are not built for that repeat-cycle duty, and they top out below the 20A and 277V this one carries.
7) Will a 20-amp switch work on a 15-amp lighting circuit?
Yes. The 20A rating on the Leviton 1223-2W is the maximum the contacts can carry, so it is fine on a 15A branch circuit and gives you headroom on heavy ballast or LED driver inrush. Standardizing a building on the 20A device also means one part number covers both 15A and 20A circuits.
8) I need a 20A three-way toggle switch in ivory instead of white - what should I order?
The Pass & Seymour CS20AC3I is a commercial 20A specification grade toggle switch in ivory. It carries the same 20A rating and specification grade as the white Leviton 1223-2W, so it is the one to use when the ivory devices and wallplates already in the building have to be matched.
9) How does the Pass & Seymour 660 Trademaster compare to the Leviton 1223-2W?
They are different classes of device. The Pass & Seymour 660 is a Trademaster grounding toggle switch, a general-purpose line. The Leviton 1223-2W is an extra heavy-duty industrial/specification grade three-way switch rated 20A at 120/277V AC, built for repeat-cycle service in hallways, stairwells, and warehouses. For a high-cycle commercial opening that needs switching from two locations, the 1223-2W is the device written to that duty.
10) Which 20A three-way toggle switch should I use on a 277V lighting circuit if I do not need a spec grade device?
The Bryant 4903W is a 3-way AC toggle switch rated 20A at 277V in commercial grade, in white. It covers 277V three-way lighting at the same 20A as the Leviton 1223-2W; the Leviton is a specification grade device rated for both 120 and 277V AC, so it is the one to carry if the same part number has to work on 120V branch circuits as well as 277V lighting.
11) Is a wallplate included with the Leviton 1223-2W toggle switch?
No wallplate is part of the 1223-2W; it ships as the switch itself. Order a standard toggle-opening plate separately, and match it to the gang count of the box. For a 3-way pair you will need a plate at each of the two locations.
