Pass & Seymour 660-BKG – Frequently Asked Questions
1) Is the Pass & Seymour 660 Trademaster switch a self-grounding switch, and do I still need a ground wire?
The 660 Trademaster is a grounding toggle switch, which means it has a grounding provision built into the device so the switch body is bonded rather than left floating. You still land the circuit's equipment ground at the device's grounding point per the installation. This is the configuration to pick when your inspector or spec calls for a grounded switch on the circuit.
2) Is the Pass & Seymour 660 switch UL listed for commercial work?
Yes. The 660 Trademaster grounding toggle switch is UL Listed and cULus Listed, so it is accepted for both US and Canadian installations, and it is used in commercial and industrial wiring as well as residential lighting and circuit control.
3) Will the Pass & Seymour 660 toggle switch fit a standard single-gang box and wall plate?
Yes. The device measures 4.195 in high, 1.25 in wide and 1.09 in deep, which is the standard toggle switch strap and body footprint for a single-gang box with a standard toggle opening plate. Depth of 1.09 in is worth checking against shallow boxes packed with conductors.
4) I need a 3-way switch for a stairwell, not a single toggle. What should I order instead of the 660?
The 660 Trademaster is a grounding toggle switch and is not described as a three-way device. For a pair of switches controlling one light, use a three-way: the Bryant 4903W is a 3-way AC toggle rated 20A 277V, commercial grade, and the Eaton Arrow Hart AH-1223GY is an industrial grade three-way rated 20A, 120/277V.
5) Can I use the Pass & Seymour 660 switch on a 277V lighting circuit?
No voltage or amperage rating is carried for the 660 Trademaster, so do not assume it for 277V lighting. When you need a confirmed 277V device, the Bryant 4801W is a single-pole 15A 277V AC toggle and the Leviton 1221 is a SPST extra heavy-duty specification grade toggle rated 20A 120/277V.
6) Is the Pass & Seymour 660 a direct swap for an existing grounded toggle switch?
It is built for grounded toggle switch replacement work, and it uses the standard toggle body and single-gang strap dimensions (4.195 x 1.25 x 1.09 in), so it goes back into an existing box behind your existing toggle-opening plate. Match the color to the rest of the room, white or black, and carry the equipment ground over to the new device.
7) What is a comparable single-pole toggle switch to the Pass & Seymour Trademaster 660-WG if an industrial grade device is specified?
The Leviton 1221 is an SPST toggle switch rated 20A at 120/277V and is built to extra heavy-duty industrial specification grade, so it answers a spec calling for an industrial or specification grade single-pole switch. The Trademaster 660 grounding toggle switch is a thermoplastic-bodied toggle switch offered in white (660-WG) and black (660-BKG). Choose the Leviton where the drawing names a grade; choose the Trademaster where a grounding toggle switch in white or black is what the job needs.
8) What is the 660 Trademaster switch body made of, and will it hold up in a high-traffic building?
The housing is high impact resistant injection molded thermoplastic, chosen to resist cracking and wear in everyday use. For apartment corridors, offices and similar repeated-use openings that is the durability argument. If your spec sheet actually calls out extra heavy-duty industrial or specification grade, look at the Leviton 1221 or 1221-2KL instead, which are listed as specification grade devices.
9) Is there a toggle switch with an indicator light for equipment I cannot see from the switch?
The 660 Trademaster is a plain grounding toggle with no pilot light. For a switch that shows when the load is energized, the Leviton 1201PLC is an industrial grade pilot light toggle switch, 1-pole, 120V. That is the one for exhaust fans, attic lights and remote equipment.
10) I am standardizing switches across a building and need ivory, not white or black. What are my options?
The Trademaster 660 is offered in white (660-WG) and black (660-BKG) only. If the building is ivory, the Leviton 1201-2I is an extra heavy-duty industrial/specification grade toggle switch in ivory. Keep in mind that is a different series, so trim and toggle styling will not match adjacent Trademaster devices.
11) Is the Leviton 1201PLC a substitute for the Pass & Seymour Trademaster 660 grounding toggle switch?
Not a direct one. The Leviton 1201PLC is an industrial grade 1-pole pilot light toggle switch for 120V, meaning the handle or lens illuminates to show circuit status. The Trademaster 660 is a plain grounding toggle switch with a satin finish and no pilot light, so swapping to the 1201PLC changes what the occupant sees at the wall.
12) I need a white 15A single-pole toggle switch rather than the Trademaster 660 - what else is there?
The Bryant 4801W is a 4-Series single-pole toggle switch rated 15A at 277V AC in white. It covers a 15A single-pole circuit where the Trademaster 660-WG white grounding toggle switch would otherwise be used.
