Intermatic EI500WC – Frequently Asked Questions

1) Will the Intermatic EI500WC timer switch work on a 120V residential lighting circuit?
Yes. The EI500WC is rated 125 VAC, 60 Hz, which covers a standard 120V branch circuit, and it installs on 15 A circuits. It's a single-pole device, so it replaces a standard single-pole wall switch controlling lights or fans from one location. If the load is switched from two locations (3-way), this is not the right control.
2) Can I use the EI500WC to control LED and CFL fixtures, or is it incandescent only?
It handles incandescent, fluorescent, CFL and LED loads, so you can put it on retrofitted LED corridor or exterior fixtures without swapping the control. Load limit is 15A at 125 VAC. It switches the load on and off on a schedule, it does not dim.
3) Does the EI500WC lose its schedule when the power goes out?
No. A built-in rechargeable battery backup holds the program through an outage, so the timer resumes its schedule when power returns instead of needing to be reprogrammed. That matters on exterior and common-area lighting where nobody notices a blank timer for a week.
4) Will the Intermatic EI500WC fit in a standard single-gang wall box?
The timer body measures 4.125 in x 1.75 in x 1.438 in (H x W x D). The 1.438 in depth is what matters in a shallow or crowded box, so on an old metal box packed with conductors check your remaining depth before you cut in. It's white, so it matches standard white device plates already on the wall.
5) How many on/off events can I program on the Intermatic EI500WC in a week?
Up to 14 ON/OFF events across a 7-day schedule, and it also runs a simple 24-hour repeating program if every day is the same. That's enough for two events a day all week, or you can concentrate them, for example different weekend hours on a clubhouse or laundry room. Programming is done on a backlit LCD, so it's readable in a dark mechanical room.
6) Can this timer run a bathroom exhaust fan or ventilation equipment, not just lights?
Yes. The EI500WC is listed for air movement and ventilation as well as indoor and outdoor lighting control, so exhaust fans and ventilation equipment are intended applications as long as the load stays within 15A at 125 VAC. Scheduling a fan on fixed daily runs is a common use in multi-family and small commercial spaces.
7) What is the random mode on the Intermatic EI500WC timer for?
Random mode varies the ON and OFF times automatically around the programmed schedule so the lighting doesn't run on an obvious fixed pattern. It's used on vacant units, seasonal properties and street-facing offices to give a lived-in look. Leave it off where you need the lights on at an exact time, such as a parking lot photocell-free schedule.
8) What is the exact part number to order the Intermatic 7-day 15A timer switch in white?
Order Intermatic EI500WC. That is the complete manufacturer part number for the white 7-day programmable timer switch rated 125 VAC, 15A, and it's a single configuration, so there are no finish or voltage options to specify. Country of origin is China.
