Pass & Seymour 1222-L – Frequently Asked Questions

1) What wire size do the terminals on the 1222-L switch take?
Side wired terminals accept #14 through #10 AWG copper or copper-clad conductors. There is no back-wire or push-in option, so plan on looping conductors onto the screws.
2) Does the Pass & Seymour 1222-L come with a key, and what key does it use?
One 1498-NT key ships with the switch. It is a normally open, key-locking toggle, so operation is restricted to whoever holds the key. If you are standardizing a building on the same key, order spare 1498-NT keys.
3) Can I use the 1222-L switch on a 277V lighting circuit?
Yes. It is rated 15A at 120/277V, so it works on both 120V branch circuits and 277V commercial lighting. The 15A rating is the ceiling, so a 20A circuit load needs a 20A device instead.
4) What is the closest key-locking alternative to the Pass & Seymour 1222-L switch?
The Leviton 1221-2IL is the nearest locking toggle switch to the Pass & Seymour 1222-L. The 1222-L is a locking double-pole, double-throw switch rated 15A at 120/277V, while the Leviton 1221-2IL is an industrial grade locking toggle rated SPST single-pole at 20A, 120/277V. So the Leviton covers a single-pole single-throw circuit at a higher amperage, and the Pass & Seymour handles a two-pole, two-throw transfer circuit. Match the pole and throw count your circuit needs first, then the amperage.
5) If I need DPDT switching but not the key lock, what should I use instead of the 1222-L?
The Leviton 1286-W is the DPDT option without a key. It is a 20A DPDT center-off toggle switch in industrial/specification grade, so it gives you the same two-pole, two-throw switching the Pass & Seymour 1222-L provides, plus a center-off position, but anyone can operate the toggle. Choose the 1222-L when the circuit sits in a restricted-access area and must only be switched by someone holding the key; the 1222-L is supplied with one 1498-NT key.
6) What is the difference between the double-pole double-throw 1222-L and a single-pole version?
The 1222-L is the double pole double throw configuration, meaning it switches two hot legs between two positions at once, which is what you need for transferring a two-wire load or a 240V/two-leg circuit between sources. If you only need one leg switched between two outputs, the single pole double throw version of the same locking switch is the correct choice.
7) Is this locking switch listed for commercial and institutional work?
It carries UL, CSA and cULus listings, which covers the usual inspection requirements for commercial and industrial installations. Contacts are oversize silver alloy for heat dissipation under load.
8) I need a 20A DPDT center-off switch instead of a locking 15A one. What else is there?
If the application needs 20 amps and a center-off position rather than a key, the Leviton 1286-W is a 20A DPDT center-off toggle in industrial/specification grade. The Pass & Seymour 1222-L is the right pick only when you need the key-locking restriction at 15A.
9) Can I use this switch as a manual motor controller?
It is described as a manual controller switch rated 15A at 120/277V for double-pole, double-throw circuit control, and manual motor and equipment control switching is one of its stated applications. Keep the load within the 15A rating.
10) What is a simpler switch than the 1222-L for basic on/off lighting at the same voltage?
For plain single-pole on/off control, the Bryant 9801 is a BR Series 1-pole AC switch rated 15A 120/277V, matching the 15A, 120/277V rating of the Pass & Seymour 1222-L without the key lock or the double-pole, double-throw contact arrangement. The 1222-L is the choice when the circuit needs to be keyed shut or needs two poles switched between two throws.
11) Will the gray 1222-L switch match the device plates already in my building?
The switch is gray with a matte finish and a thermoplastic (nylon) housing, which is the common commercial device color rather than white or ivory. If your existing openings are white, the toggle will not match, so budget for plates and accept the color difference on the toggle itself.
12) How are the Pass & Seymour 1222-L switches packaged for a multi-unit job?
They are packed 10 each, which suits buying by the carton when you are keying several mechanical rooms or restricted-access areas at once. Country of origin is Mexico.
13) Can I use a combination switch device in place of the 1222-L in a single gang box?
Not for the same purpose. The Eaton 275VBOX is a commercial grade decorator duplex combination switch with auto-ground, rated 15A in white, which puts two independent switch controls in one opening. The Pass & Seymour 1222-L is one key-locking double-pole, double-throw device rated 15A at 120/277V that fits standard device boxes or NEMA 1 sheet steel enclosures. Pick the Eaton when you need two separate switched loads from one gang; pick the 1222-L when one circuit must be keyed and switched on two poles.
