Intermatic T104R – Frequently Asked Questions

1) What does DPST switching mean on this timer, and can it control a two-pole 240V load?
DPST means double pole, single throw: the T104R opens and closes two hot legs at once from one timing mechanism. That lets it switch both ungrounded conductors of a 208V or 240V load, or two separate 277V legs together. It is a single schedule driving both poles, not two independent circuits on different times.
2) Can the Intermatic T104R be mounted outdoors on a building exterior?
Yes. The T104R ships in a gray metal indoor/outdoor enclosure, so it can be surface mounted on an exterior wall for parking lot, sign, or security lighting as well as indoors in a mechanical room.
3) How many on/off times a day can I program on this mechanical time switch?
Up to 12 ON/OFF operations per day, with a minimum of one hour between a trip pin and the next. So you can run a morning and evening lighting block plus midday cycles, but you cannot schedule anything shorter than an hour apart. If you need 15 or 30 minute resolution, a mechanical 24-hour dial of this type is the wrong tool.
4) How much wall space do I need to mount the T104R enclosure?
Allow for an enclosure measuring 10.125 in high, 6.5 in wide and 3.625 in deep, plus clearance to swing the door and land conduit. Worth checking before you commit a spot in a crowded electrical closet or on a narrow pilaster.
5) Can maintenance staff turn the lights on manually without disturbing the schedule?
Yes. The timer has a manual override lever that lets someone switch the load on or off right at the cabinet, then hand control back to the dial at the next scheduled trip. Useful for after-hours work or testing a circuit without pulling pins.
6) Is this a 24-hour timer only, or does it skip weekends?
It is a 24-hour dial. The same schedule repeats every day, so the T104R does not differentiate weekdays from weekends or holidays. For a schedule that varies by day of week you need a 7-day astronomic or electronic time switch instead.
7) I have an existing Intermatic enclosure on the wall. Can I just swap the mechanism in?
The T104R mechanism can be installed in most Intermatic enclosures, so if you already have a case and raceway in place you can reuse the mounting and conduit rather than re-drilling a new box. Confirm the existing can is sized for the T100 Series chassis.
8) Is the T104R suitable for standardizing outdoor lighting control across a portfolio of buildings?
It is a reasonable fleet standard where every site runs 208-277 VAC lighting and wants a simple daily on/off. The T100 Series is a long-running mechanical platform, the applications listed are indoor lighting control, outdoor lighting control and general ON/OFF scheduling, and the metal cabinet suits both interior panels and exterior walls. Sites fed at 120V will need a different voltage model, so the portfolio is only truly standardized if the supply matches.
9) What is the exact manufacturer part number and where is it made?
The part number is Intermatic T104R, UPC 078275000124, and it is manufactured in Mexico. It sits in the T100 Series mechanical time switch family.
