Intermatic T103P – Frequently Asked Questions

1) Will the Intermatic T103P time switch work on a 120V circuit, and does it switch both legs?
The T103P runs on 120 VAC, 60 Hz and switches DPST, meaning both poles open and close together. That gives you a two-pole break on a 120V load rather than switching only the hot leg. It is a line-voltage mechanical switch, so the same 120V feed that powers the clock motor is the supply being switched.
2) Can an Intermatic T103P mechanical timer be mounted outside?
Yes. The T103P ships in a gray plastic indoor/outdoor enclosure, so it can go on an exterior wall for parking lot, sign, or security lighting as well as inside a mechanical room. The enclosure measures 10 in high, 6.5 in wide and 4 in deep, so allow that footprint plus door swing when you pick the mounting spot.
3) How many on/off cycles a day can I program on the T103P, and how short can each one be?
Up to 12 ON/OFF operations in a 24-hour cycle, with a 1-hour minimum interval between them. That works for lighting schedules, but if you need a load cycled for fifteen minutes or repeated every half hour, the 1-hour minimum rules the T103P out.
4) Does the T103P repeat the same schedule every day, or can I set different times for weekends?
It is a 24-hour timer. The dial makes one revolution per day and repeats the same trippers every day, with no separate weekend or day-of-week programming. For skip-a-day or weekday/weekend schedules you need a 7-day time switch instead.
5) Can I turn the lights on manually without changing the timer program?
Yes, the T103P has a manual override lever so maintenance staff can flip the load on or off immediately, and the clock keeps running its programmed schedule underneath. Handy when a property manager needs lot lights on early for an evening event.
6) Mechanical timer versus an electronic one for lighting control, which makes more sense?
The T103P is mechanical, so the schedule lives on a dial with physical trippers instead of in firmware. There is nothing to reprogram after a power outage and no display to fail, which is why the T100 Series is still specified for exterior lighting. The trade-off is resolution and flexibility: a fixed 24-hour cycle, 12 operations max, 1-hour minimum interval, and no astronomic sunrise/sunset tracking. If you want the lights to follow the seasons automatically, you want an astronomic or electronic control, not this.
7) Can the T103P switch the lighting circuit directly, or do I need a contactor behind it?
For most loads it switches directly, no separate contactor needed. That is the point of the T100 Series design in a lighting retrofit. Size the circuit to the timer's own switch rating before you commit it to a heavy multi-fixture branch, and for very large or motor loads run the timer as a pilot to a contactor instead.
