I wanted to use this to turn on & off Christmas lights. I currently have a light switch controlling my outside outlets. There is 1 supply line in and 2 feeder lines out. The way I have it now the manual switch works but the timer is not running. Which terminals need to be connected to power the clock timer. A diagram would be really help full. I'm not much a electrician as you can tell. Thank you.....
Asked by: Dave
This is a 240v timer there for needs a 240v breaker to operate. In a nut shell two lines in but, **** YOU CAN NOT USE TWO SEPARATE BREAKERS (unless they are bonded together). Your local HD should be able to help you figure it out or hire an electrition to be sure there are no issues. Hope this helps.

t104r v. t104r3

What is there a difference between the t104r and the t104r3?
Asked by: MikeB
The only difference that I can tell is the instruction sheet has been rewritten, with more emphasis on the instructions.

150 VOLTS 250Watts light

Will this be able to handle that?
Asked by: Sammul
Not sure what you are asking. The voltage going into a home is 2 x 120. All your standard outlets, switches, etc are all 120v. There are things that use 240v but those are hard wired or have a very different plug so you can't use it for a 120v item.

T100 Series 40 Amp 208-277-Volt DPST 24 Hour Mechanical Time Switch with Outdoor Enclosure is rated 4.6 out of 5 by 27.
Rated 5 out of 5 by from Intermatic Performance It took 45 minutes to throw circuit breakers off, take off old swimming pool pump, put on Intermatic T100, wire the Intermatic 240 volt/40 amp, program the automatic on/off function, flip the circuit breakers back on, and use the manual override to test the new switch. Perfect, and has continued to be so.

Rated 4 out of 5 by from now the lesser of 2 I have been around this product now for 50 years due to I am a electrical contractor and my dad was and my grandfather was so I have seen this company change hands and now they have closed production in the u.s.a. and moved to mexico, a few years ago they had American flag on everyone with made in the u.s.a. I noticed it gone but not a mexico flag so they must not be proud of coming from mexico.

Rated 5 out of 5 by from The Gold Standard for Timers This time switch was purchased for use with pool equipment and replaced an earlier model with a plastic case. The new weatherproof enclosure is vastly superior to the older model which eventually suffered from weather exposure, became brittle and broke. This is a great example of product improvement. They left what worked well alone and only changed what needed to be improved.

Rated 4 out of 5 by from Works as Advertised Bought this yesterday to replace a 40+ year unit that finally died, it is used for turning power to a pump for the swimming pool. It was the same size as the old, this version is a lot easier to mount as you can easily out pull the timing controller to mount the box. The model number even matches the old one! That was convenient. I got it installed with no problems, hopefully this lasts just as long. Everything seems the same as the original.

Rated 5 out of 5 by from Perfect Replacement I bought this timer as a replacement to run my pool filter pump (the old one was broken, and the company who made no longer is in business for a replacement timer mechanism). The box mounted in it's place perfectly, and was a breeze to install and wire in. To top it all off, this unit was very inexpensive vs going to a pool supply house for the same type of replacement. I'm very pleased.
