Customer Questions & Answers

Can this timer turn on 2 separate 120v circuits at the same time?

Asked by: Mayate
It's got additional terminals to run to other loads, but best to ask Intermatic to make sure you don't overload the timer circuits.

What would make motor burn out

Asked by: Rob
Short circuit from power surge, or water infiltration, which did not trip the circuit breaker. Or, possibly some mechanical failure that prevented the dial from rotating, or incorrect wiring in the motor, or connection. Yes, it could have been a mfr defect in the timer.

I have a T104r, is this compatible?

Asked by: Sean1
No. The T104 is a 208 - 277 volt timer, while the T101 is a 125 volt timer. The internal motor will not work correctly to maintain the proper operation.

T100 Series 40 Amp 125-Volt 24 Hour SPST Mechanical Time Switch with Outdoor Enclosure is rated 4.8 out of 5 by 23.
Rated 4 out of 5 by from Good Product... But... Terrible Instructions Good timer similar to pool timers, which are mechanical - which are much more reliable than the digital, electronic timers used to control lights, which are at risk for failure due to shorts from power surges, and from water infiltration. If this timer experiences a short, it merely trips the circuit breaker, which can be reset and your back in business, unless the short was so bad that it burnt some wires in the timer. However, the installation instructions are not simple and clear enough for most layman homeowners to easily understand the wiring connections (unless you've got some electrical wiring experience) - they could have been made much clearer for those of us, who have very little wiring experience (who probably should hire an electrician to install it anyway). But... if you don't want to wait on the electrician to show... Here's a YouTube video that explains it all very clearly - if you want to DIY it anyway. https://www.youtube.com/watch?v=E3JKZd5NGbk Just make sure the wire from your breaker box, which carries the electricity (typically black) is connected to terminal "1", the wire that continues to carry the electricity to your light fixture (typically black) is connected to terminal "2", and that the wires that do not carry the electricity from your breaker and to your light fixture (neutral wires, which complete the circuit, typically white or red) are both connected to terminal "A". And you'll be fine. The wiring diagram from the mfr - shows the same thing, once you understand it, but... if you don't... "a video is worth a 1000 words / diagrams." Come on Intermatic... get with the program... it's 2016... YouTube is where its at!!!

Rated 5 out of 5 by from T100 SERIES 40 AMP 125-VOLT 24 HOUR SPST MECHANICAL TIME SWITCH WITH OUTDOOR ENCLOSURE what can you say other than it works and looks good. On the other hand at the same purchase time I needed a 125 volt timer that controls two separate circuits and Home Depot dosn't stock it. some times you have to split the circuit on another breaker if you have exceeded the wattage.I could have bought two of these but instead ended up at Grainger and used this timer on a pool light.It seems to be the norm,every time I need something they dont have or their out of. we also need 10's and 12's in the rough sawn cedar ,its the only economical wood you can use for outside finish. P T is too rough ,bent,,knotty, not treated enough these days and and poplar is too expensive for people on a buget. With cedar you can use the rough side or smooth side and it looks great on a budget.Pine will not last very long no matter what. And why are you stocking that plastic spline junk for screens the stretch spline is adjustable for spline grooves on old and new frames.

Rated 4 out of 5 by from WORKS AS DESCRIBED, GREAT PRICE! The Timer is as described. It was easy to use for a DIY'r (electrician recommended)! The only thing I would like to see is a better manual on/off option with out messing with the pins.

Rated 4 out of 5 by from decent box and this is a replacement unit. old one lasted 10 years in a pool environment. you can add as many timer pins as you need for cycling

Rated 4 out of 5 by from Easy to program poo pump l timer The timer is very easy to program unlike some of the electronic units I have owned in the past. I would recommend sealing the knock out holes where the electrical wires go in and out with environmental puddy to keep spiders from getting in the box and mucking up the mechanical gears.
