Intermatic T175 – Frequently Asked Questions

1) Can the Intermatic T175 time switch be installed outdoors or in a wet location?
No. The T175 ships in a gray indoor metal enclosure and is intended for indoor installation only. For an exterior wall, a pool pump pad, or anywhere exposed to weather, you need a time switch in a raintight outdoor enclosure instead, or the T175 mechanism mounted inside a weatherproof cabinet you supply.
2) Will the Intermatic T175 handle a 40 amp lighting circuit at 120V?
Yes, up to 40 A per pole at 120 VAC, 60 Hz. That covers most indoor lighting banks and single-phase equipment circuits in that range. The timer motor itself is 120 V only, so on a 208/240 or 277 V system you need the version of the switch matched to that supply voltage, not the T175.
3) What does the skip-a-day feature on the T175 actually do, and how is it different from a 7-day timer?
Skip-a-day lets you omit the programmed ON cycle on selected days while the rest of the week runs normally, using day-skipper screws on the dial. It is still a 24-hour dial, not a true 7-day program, so every day that runs uses the same ON/OFF times. If you need different hours on different days, say a different Saturday schedule for a retail space, you want a 7-day time switch rather than this one.
4) Does the Intermatic T175 come with the trippers, or do I need to order more?
It arrives with one ON tripper, one OFF tripper, and three day-skipper screws, which is enough for a single daily on/off cycle plus three skipped days. To run additional cycles, up to the 10 per day the switch supports, you will need to add tripper pairs separately.
5) Is the Intermatic T175 a replacement for a T100 series timer?
The T175 is similar to the T100 Series and carries the same 40 A per pole load rating, with skip-a-day scheduling added on the dial. If you are replacing a 120 V T100-style indoor mechanical timer and want the ability to omit selected days, the T175 covers the same load duty. Confirm your existing unit is 120 V, since the T175 runs on 120 VAC, 60 Hz.
6) Will the Intermatic T175 fit in the space where my old timer was mounted?
The enclosure measures 7.875 in high, 5.125 in wide, and 3.437 in deep, so allow a panel space a little larger than that plus room to swing the door and route conduit. Measure your existing backboard footprint against those three numbers before you pull the old unit.
7) How many on/off cycles per day can I program on the Intermatic T175?
Up to 10 ON/OFF operations in a 24-hour period, with a one-hour minimum between an ON and an OFF. That one-hour floor matters for HVAC and motor loads, it keeps the timer from short cycling equipment, but it also means you cannot schedule a 15 or 30 minute run with this switch.
8) Can I switch the load on manually without losing the T175 program?
Yes. The T175 has a manual override that turns the load on or off immediately and leaves the dial program intact, so the next scheduled change still happens. Useful for maintenance crews who need lights up outside normal hours without reprogramming the timer.
9) Can the T175 control two circuits, or switch one load on while another goes off?
The contact arrangement is 1 NO / 1 NC, so you get one normally open and one normally closed contact driven by the same dial. That lets you energize one load while de-energizing another on the same schedule. It does not give you two independently timed circuits.
10) Is a mechanical dial timer like the T175 the right choice over a digital/astronomic timer for parking lot or exterior lighting?
For exterior lighting that should follow sunrise and sunset, a dial timer is the wrong tool, fixed clock times drift against daylight through the year and you end up resetting the trippers seasonally. The T175 is built for indoor lighting control and straightforward ON/OFF scheduling at set hours, in an indoor enclosure. Use it for interior lighting banks, equipment run windows, and facility load shedding; use an astronomic or photocell-based control for anything tracking daylight.
11) What is the exact part number and origin for the Intermatic T175 so I can match it on a submittal?
Order it as Intermatic model T175, manufacturer part number T175, made in Mexico. Spec line reads: 24-hour mechanical time switch, skip-a-day, 40 A per pole, 120 VAC 60 Hz, 1 NO / 1 NC, gray indoor metal enclosure.
