Intermatic T104P – Frequently Asked Questions

1) What does DPST mean on the Intermatic T104P, and can it switch both legs of a 240V load?
DPST is double-pole, single-throw: the T104P opens and closes two hot legs at the same time from one time setting. That is what you want on a 208V, 240V or 277V two-hot-leg load, since both conductors are broken when the timer is off. It is one switched circuit, not two independently timed ones.
2) How many on/off cycles a day can I schedule with the T104P timer?
Up to 12 ON/OFF operations in a 24-hour cycle, with a one-hour minimum between an ON and the next OFF. Each pair of trippers on the dial gives you one ON and one OFF, so a simple dusk-to-dawn lighting schedule uses a single pair and leaves the rest for staged or midday loads.
3) Can I mount an Intermatic T104P time switch outdoors on a building exterior?
Yes. The T104P comes in a grey plastic enclosure rated for indoor or outdoor mounting, which is why it gets used on parking lot, security and exterior area lighting as well as interior circuits.
4) Is the T104P a 7-day timer or a 24-hour timer?
It is a 24-hour timer. The T104P repeats the same schedule every day, so it cannot run a different program on weekends. If your building needs weekday-versus-weekend schedules, you need a 7-day astronomic or electronic time switch rather than this 24-hour T100 series dial.
5) What wall space do I need to allow for the Intermatic T104P enclosure?
Plan for a footprint of 10 in high by 6.5 in wide with a 4 in depth off the wall. Leave clearance in front of the door so the dial and trippers can be reached for setting and for the manual override lever.
6) Can maintenance staff turn the lights on without changing the timer schedule?
Yes. The T104P has a manual override so the load can be switched on or off by hand without disturbing the trippers. Once the next scheduled tripper comes around, the timer resumes its normal program.
7) Is a mechanical time switch like the T104P still a good choice compared with an electronic timer?
For a fixed daily lighting schedule it holds up well. The T100 series dial has no program to lose, no battery to replace, and a motor-driven dial that anyone on a maintenance crew can read and reset by moving the trippers. The trade-off is one-hour minimum intervals and a single repeating 24-hour program; if you need minute-level precision, seasonal sunset tracking, or different weekday schedules, go electronic.
8) What part number do I order for the 208-277V DPST Intermatic 24-hour timer?
Order Intermatic T104P. That is the 24-hour mechanical time switch with 208-277 VAC, 60 Hz operation, DPST switching and the indoor/outdoor plastic enclosure. Other suffixes in the T100 family change voltage, pole configuration or enclosure type, so the P designation matters if you want the plastic outdoor case.
