Intermatic T7401B – Frequently Asked Questions

1) Can an Intermatic T7401B mechanical time switch be mounted outdoors or in a wet location?
No. The T7401B comes in a Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It carries no rating against rain, splashing water, or washdown. For a parking lot pole, a rooftop, or an exterior sign circuit, you need a time switch in a raintight outdoor enclosure. Inside an electrical room, a retail back-of-house, or a mechanical closet, the metal Type 1 box is the right fit.
2) Can I set a different lighting schedule for Saturday and Sunday than for weekdays?
Yes, that's the reason to pick the T7401B over a 24-hour timer. It's a true 7-day mechanical time switch, so each day of the week gets its own ON and OFF times. A 24-hour dial repeats the same schedule every day, which means a retail store or office building with reduced weekend hours ends up burning lights on Sunday. With the 7-day dial you program the short weekend day once and leave it.
3) What is the shortest ON time I can program on an Intermatic T7401B?
3.5 hours. The minimum interval between an ON and the following OFF is 3-1/2 hours, so the T7401B will not do short cycles. If you need a circuit to run 20 minutes, or to pulse a few times an hour, this mechanical switch cannot be set that way and you want a timer with a shorter minimum interval or an electronic control. For lighting that goes on at dusk and off at close, 3.5 hours is no constraint at all.
4) Will the Intermatic T7401B lose its program during a power outage?
No. It has 16-hour power failure carry-over, so the clock rewinds and keeps the preset schedule through an outage up to that length and picks back up on time with no reprogramming. Past 16 hours without power the clock time has to be reset. For a property manager running lights across multiple buildings, that's the difference between one storm and a round of site visits to reset timers.
5) How many separate circuits can one Intermatic T7401B control?
Four. The switching configuration is 4-SPST, meaning four independent single-pole, single-throw circuits in one enclosure, each switched on the same 7-day program mechanism. That's useful where you want a bank of loads dropped together, say four lighting circuits in a retail space, without four separate timer cans on the wall. SPST also means each circuit is a simple make/break, not a transfer between two loads, so if you need to switch a load between two sources you need a double-throw control instead.
6) How much wall space do I need to mount an Intermatic 7-day time switch enclosure?
Allow for a box measuring 13.125 inches high, 9 inches wide, and 3.75 inches deep, plus clearance to swing the cover and to pull conduit into the sides or bottom. That footprint matters in a crowded electrical closet, since it's a good deal taller than a typical 24-hour dial timer. Gray painted metal housing, with a separate grounding terminal inside.
7) What is the Intermatic part number for the 7-day 120V 4-SPST time switch?
Order it as Intermatic T7401B. That's the model to hand a distributor or put on a submittal, and it identifies the 120 VAC 4-SPST configuration in the indoor metal enclosure specifically. Intermatic's 7-day mechanical line uses close part numbers for different voltage and switch configurations, so the full suffix matters when you're standardizing a facility on one model.
8) Is a mechanical time switch or an electronic timer better for commercial lighting control?
A mechanical time switch like the T7401B is the choice when you want a schedule that a maintenance tech can read and change at the wall without a manual or a battery. The dial shows the program, and the 16-hour carry-over holds it through outages. The tradeoffs: the minimum interval is 3.5 hours, there's no astronomic dusk-to-dawn tracking, and no holiday skip. If your schedule needs short cycles, sunrise and sunset following, or holiday overrides, an electronic time switch is the right type. For a fixed store-hours lighting schedule, the mechanical unit is fewer things to fail.
9) Can the Intermatic T7401B switch a 240V or low-voltage load if the clock is on 120V?
The clock motor has its own terminals, separate from the switched circuits, so the timer body can be powered from a 120 VAC, 60 Hz source while the four SPST contacts carry loads that are not on that same line. That's the installation flexibility the separate clock terminals exist for. What the contacts themselves are rated to carry is a function of the switch rating, so match your load to the contact rating on the unit's own nameplate before you land the conductors.
10) Is there a ground terminal in the Intermatic T7401B enclosure for the equipment grounding conductor?
Yes, the metal enclosure has a separate grounding terminal, so the equipment grounding conductor lands on its own screw rather than sharing a neutral or load terminal. On a metal-can control in a commercial install that's what an inspector looks for, and it keeps the housing bonded independent of the switched circuits.
11) What color is the Intermatic T7401B time switch enclosure?
Gray painted metal. It reads as standard equipment-room finish rather than something meant for a finished tenant space, so if it's landing on a wall in a lobby or a retail sales floor you may want it inside a closet or behind a door. In a mechanical room or back-of-house it matches everything else on the wall. Made in Mexico.
