Intermatic T101 – Frequently Asked Questions

1) Will the Intermatic T101 time switch work on a 120V lighting circuit?
Yes. The T101 is built for 120 VAC, 60 Hz single-phase power, and it switches SPST (single pole, single throw), so it breaks one hot leg to the load. That makes it a straight fit for a standard 120V indoor lighting branch circuit. If your load is 240V or you need two poles broken, the T101 is the wrong device in the T100 family.
2) Can the Intermatic T101 be mounted outdoors or in a wet location?
No. The T101 ships in an indoor metal enclosure with a gray finish, so it belongs inside a conditioned or dry space: electrical rooms, back-of-house, retail and office ceilings spaces, mechanical closets. For an exterior wall or a damp location you need an outdoor-rated enclosure version instead.
3) How many on/off cycles a day can the T101 mechanical timer be set for?
Up to 12 ON/OFF operations in a 24-hour cycle, with a one-hour minimum between a trip on and a trip off. So it will handle a lobby light that cycles morning and evening, or a sign that runs several blocks a day, but it cannot do short interval duty like 15 minutes on, 15 minutes off. For anything under an hour you need a different timing product.
4) Will the same T101 timer work for both weekday and weekend schedules?
No. The T101 runs a 24-hour dial, meaning whatever trippers you set repeat every single day including Saturday and Sunday. If a retail store or school needs a different Sunday schedule, you need a 7-day timer rather than this 24-hour unit.
5) How much wall space do I need to mount an Intermatic T101 timer?
Plan on a footprint of 7.875 inches high by 5.125 inches wide, with the enclosure standing 3.437 inches deep off the mounting surface. Allow for the door swing and conduit entries on top of that, which matters in a crowded electrical closet or when you're stacking timers next to a panel.
6) Can I turn the lights on manually without disturbing the timer schedule on an Intermatic T101?
Yes. The T101 has a manual override so maintenance or staff can flip the load on or off at the enclosure, and the dial keeps running its 24-hour program. Useful in a school or office where housekeeping needs light after the scheduled off time.
7) Is a mechanical time switch like the T101 better than an electronic timer for my building?
The tradeoff comes down to what you want happening when the power blinks. The T101 is a mechanical 24-hour dial with no electronics and no dependence on backup power, so there is nothing to reprogram after a trip, though the dial will lose the time it sat dead and needs resetting. An electronic timer holds the schedule through an outage and can do astronomic or seven-day programs, which the T101 cannot: it repeats the same set of trippers every day. For plain daily lighting on a fixed schedule, the mechanical unit is the simpler service call.
8) What is the exact part number and series for the Intermatic gray indoor 24-hour timer?
The part number is T101, part of Intermatic's T100 Series mechanical time switches. It is made in Mexico. When you are standardizing across a property, quote it as Intermatic T101 so you get the 120V SPST indoor version and not another T100 variant with different voltage or pole configuration.
9) What kinds of loads and facilities is the Intermatic T101 used for?
It is spec'd for indoor lighting control and general ON/OFF timing and scheduling. In practice that means store and sign lighting, office and corridor lights, exhaust fans on a daily schedule, and similar fixed-schedule loads in retail, office, school, and healthcare buildings. Anything that needs to come on and go off at the same clock times every day is what this dial is for.
