Pass & Seymour 1250 – Frequently Asked Questions

1) What does SPDT mean on the Pass & Seymour 1250 switch, and what can I wire to it?
Single pole, double throw. The 1250 switches one line between two separate loads or circuits rather than simply on and off, which is why it gets used for equipment selection, generator transfer and motor control center duty. It is rated 15A and wired through side terminals.
2) Does the Pass & Seymour 1250 locking switch come with the key, or do I order that separately?
The key ships with it. The 1250 includes the 1498-NT key, so you can put it in service without a separate order. If you are standardizing a building on key-operated switches, order extra keys as loose stock for the techs who need them.
3) Can I mount the 1250 locking switch in an industrial enclosure instead of a standard wall box?
Both work. The 1250 installs in a standard device box or in a NEMA 1 sheet steel enclosure, which is the indoor, non-dust, non-washdown enclosure type. For wet, oily or washdown areas you need a device rated for that environment, not this one.
4) What is the closest alternative to the Pass & Seymour 1250 if I need a key-locking switch at 20A instead of 15A?
The Pass & Seymour 1250 is a 15A single pole double throw locking switch with an included 1498-NT key. If the circuit calls for a higher rating, the Bryant 4802L 4 Series single-pole locking AC switch is rated 20A at 277V. The trade-off is the switching configuration: the 1250 is SPDT, so it transfers a common leg between two outputs, while the 4802L is single-pole, a simple on/off on one circuit. Use the 4802L only where you need locked on/off control, not two-position transfer.
5) For a high-current DC disconnect, is the Pass & Seymour 1250 the right switch or do I need something else?
The 1250 is a 15A wiring device rated for standard device boxes and NEMA 1 sheet steel enclosures, wired with #14-#10 AWG copper on side terminals - it is a control-circuit and branch-circuit switch, not a power disconnect. For DC power switching, the Bussmann TPHCS-250 TPH Series high-current switch is rated 80 Vdc with a 100kA short circuit current rating. Those are different classes of device; specify by the system voltage and fault current on your drawing.
6) What wire size do the terminals on the Pass & Seymour 1250 take?
Side-wired terminals accept #14 through #10 AWG copper or copper-clad conductors, with fiber insulating barriers between terminals. That covers a standard 15A branch circuit on #14 and gives you room if the run was pulled in #12 or #10 for voltage drop.
7) Can I use the 1250 as a DC disconnect on a battery or solar circuit?
It is not the device for that. The 1250 is an AC-rated general use switch listed for standard device boxes and NEMA 1. For high-current DC service, the Bussmann TPHCS-250 in the TPH series is rated 80 Vdc with a 100kA SCCR, which is a different class of product entirely.
8) If I do not need the locking key, what is a simpler switch than the Pass & Seymour 1250 at the same 15A rating?
The Pass & Seymour 1250 carries a locking mechanism with a key, which is what you pay for when you need to restrict operation of a transfer or isolation circuit. Where no access restriction is required, the Bryant 9801 BR Series 1-pole AC switch is rated 15A at 120/277V and operates as a standard toggle. Note that it is a 1-pole device, so it will not replace the 1250's double-throw transfer function - only its on/off duty.
9) Can I use a lighted switch like the Bryant 4801GLI in place of the Pass & Seymour 1250?
Not as a functional equivalent. The Bryant 4801GLI is a 4-Series lighted AC switch rated 20A at 277V, built so the toggle is visible in a dark space. The Pass & Seymour 1250 is a 15A SPDT locking switch whose purpose is controlled, key-restricted transfer between two circuits in panels and generator transfer applications. Swapping in a lighted switch gives you indication but drops both the double-throw configuration and the key lock.
10) Will the brown 1250 match the other devices on my job, and what is it made of?
Body, cover and toggle are molded nylon in brown with a matte finish, so it reads as a standard commercial brown device rather than a gloss thermoplastic. If the rest of the opening is ivory, white or gray, this one will stand out.
11) Why does the 1250 use oversize silver alloy contacts, and does it matter for inductive loads?
Oversize silver alloy contacts are specified for longer service life and better heat dissipation under load, which is what you want on repeated switching in motor control centers and transfer applications. This is a general-use 15A switch, so size it to the actual load current it will carry.
12) What is the manufacturer part number and where is the Pass & Seymour 1250 made?
The catalog number is 1250 from Pass & Seymour, country of origin Mexico. Quote that number directly when matching existing devices in a panel so you get the SPDT locking version and not a standard toggle.
13) How does the Pass & Seymour 1250 differ from a Bryant CSB series wiring device switch?
The Bryant CSB2BW is a DPA Series 277V wiring device switch. The Pass & Seymour 1250 is a 15A SPDT device in brown nylon with a matte finish, oversize silver alloy contacts and a key lock, cULus listed. If you are standardizing a panel on brown nylon devices with keyed operation and two-position transfer, the 1250 is the one to hold the line on; the CSB is a different series and will not match it on appearance or function.
