Make sure the clock is set to the right time. If the timer is clock is set and the on time is 7:00 pm, then it should be off before that. (past 7:00am). if all is correct, it should do it's job until the power fails. At which time you need to set the clock again.

SOURCE: Triing to install intermatic t103 please help.

T103 has 120Volt clock motor, so we can wire this timer.

T103 timer is rated for 30 amps and 2horsepower and your blowers use 28 amps.
So we're getting close to max on the timer. Hopefully blowers won't all be started at one time since motors draw maximum amperage when they start.
However, you need 30 amp breaker and orange 10 gauge wire for that much amperage >> unless only one blower is turned ON at any given time.
Always match wire size, amperage of breaker and amperage of Load or it will trip the breaker.
If you put 30 amp breaker on size 10 wire it is good. But 30 amp breaker on smaller size 14 or 12 gauge wire is fire hazard.

Look at the basics:
You have 2 cables.
One cable comes from breaker box.
Other cable goes to three 120V plugs (120V is same as 110V).

Each cable has black-wire, white-wire and bare-copper-ground-wire.

How to wire the timer.
Timer has 5 terminals: A 1 2 3 4

A) Cable from breaker box:
White wire from breaker connects to terminal A
Black-wire from breaker connects to terminal 1

B) Cable going to 3 plugs
Black wire to plugs connects to terminal 2
White wire to plugs connects to terminal A
Ground wires connect to green ground screw.

Terminals 3 and 4 are not used in this case.
Here is a wiring diagram that shows 120Volt from breaker box and 120Volt going to Load

How connect a new intermatic t104r 120v


T104 timer is 240Volts.
Not 120Volt
You can convert timer into 120V by changing clock motor from WG1573 to WG1570. This action will convert the T104 into T103.
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html

The T104 timer can be wired many different ways:

We install the timer and it does not work automatically. We can switch it on only manually


You posted under T103 Intermatic 120V timer.

Sounds like you wired the timer wrong:
Timer has 120V clock motor and requires Hot from breaker on terminal 1, and Neutral from breaker on terminal A. This will power clock motor.
If you have any of the wires reversed, timer will do what you describe.

Can I used the T103M dpst spst timer for christmas lights? I would be coming off 2 20amps breakers in a single slot. I relly don't understand what a dpst and spst are (what they do) I am trying to hook up...


T103M is 120Volt timer that can handle all the Christmas lights.
Minimum on-off time 1 hour.
Rotate dial until current time lines up with silver pointer.
Set on-off trippers on dial.
Let's go step by step.

1) T103 has terminals A 1 2 3 4 >> terminals are also called poles
DPST (double pole single throw) and SPST (single pole single throw) are two different ways to wire this particular timer.
T103 timer can be wired numerous ways... but your project is not complicated.
DPST means timer turns off two terminals/poles (double pole) with each click/throw of timer switch (single throw)
SPST means timer turns off one terminal/pole (single pole) with each click/throw of timer switch (single throw)

2) T103 timer is ST single throw, all the lights come on at same time. So this timer is 1 channel.
1 channel timers are either ON or OFF and everything turns on-off at same time.
You cannot stagger on-off times with 1 channel timer.
If you want upstairs and downstairs lights to come ON at different times, you need two timers .. or a 2-channel timer (which is different ballgame).

3) T103 timer has 120Volt clock motor that is connected to terminals A and 1.
Look at timer and you can see small white wires connected to A and 1 terminals that power 125V clock motor.
When wiring this timer, your wires from 20 amp breaker box connect to terminals A and 1.
Black hot wire from breaker must connect to terminal 1
White neutral wire from neutral busbar must connect to terminal A
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
http://waterheatertimer.org/B220C.html

4) Terminal 1 must be hot so when timer switch clicks ON, it sends power to terminal 2.
Your load wires connect to terminals A and 2
I made simple drawing of SPST option showing how to wire T103 to 3 receptacles.
Fixya downgrades image so it's hard to see.
Hot wire to terminal 1
Load wire to terminal 2
Neutrals on terminal A
To see image larger:
http://waterheatertimer.org/images/110-600-21Kb.jpg

geno_3245_171.jpg
If you want to wire timer for DPST, which is necessary for loads exceeding 2 horsepower (1500 Watts) on each terminal
Notice black jumper wire from terminal 1 to terminal 3
Notice all white neutral wires to terminal A
To see image larger:
http://waterheatertimer.org/images/110-600-17Kb.jpg
geno_3245_172.jpg
I made third image for guy who was wiring high amperage blowers, that show wiring for two T103 timers. Having two timers would let upstairs and downstairs lights come on at different times.

I have an Intermatic T103 DPST timer installed now (120v). The clock mechanism has failed. I bought Tork 1103 guts to replace it. The wiring is a bit different. Can u map for me which wires go to which...


T-103 has 120V clock motor with 5 terminals A 1 2 3 4
Tork 1101 has 120V clock motor with 4 terminals L 1 X 2

T103 is DPST and can control one-or-two 120Volt loads, or one-or-two 240Volt loads.
Tork 1101 is SPST can control one 120Volt load

Common ground between these timers one 120 Volt load
Changeover for one 120 Volt load:
White wires T103 terminal A go to Tork terminal X
Black wire T103 terminal 1 goes Tork terminals L and 1 (there is brass connector plate that connects L and 1 - if connector is missing, jumper between L and 1)
Black wire on T103 terminal 2 goes Tork terminal 2

If Load requirement is greater than T1101, Grainger sells T103 clock motor for $16

I having troble with my t103 timer to turn the lights on manualy i try to set the timer but for some reason doesn't work what can i do ???


T103 Intermatic timer has 120Volt clock motor and can control 120V or 240V Loads.
Wiring for timer is shown on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

Troubleshoot T103:
1) Manual override is working correctly, and it snaps crisp and clean, and Load turns on-and-off.
That means timer is basically good.

2) Next look to see if yellow dial is rotating.
If dial is not rotating, then 120Volt clock motor needs to be replaced.
Take photo of wiring and mark wires before starting.
Remove two white wires connected to screw terminals 1 and A.
Snap timer mechanism out of box, clock motor is on back of timer.
Use small star screwdriver to remove old clock motor.
Reattach white wires on terminals 1 and A, tighten screws very tight.
Reset current time: lift and rotate dial until current time lines up with silver pointer.
Grainger sells 125V clock motor:
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

3) If dial is rotating, but gets stuck at certain times, or runs slow, then replace clock motor.

4) If dial is rotating, and trippers are attached to dial, but timer does not turn ON, then trippers are worn down and need to be replaced.
Grainger sells the T103 trippers
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search

5) How Intermatic mechanical timers work:
Dial with ON-OFF trippers is rotated by clock motor.
Trippers on dial contact ON-OFF lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Lever moves electrical contacts on back of timer that turn Load ON-OFF.
Manual override lever clicks back and forth with each ON-OFF action.

Have intermatic t103 time switch, 240 v supply, clock motor not turning. what the correct wiring for the clock. 2 white wires...


Maybe-bad news.
The link below shows wiring for the T-104, T-103 and T-101
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

For a 240V installation, the correct timer is the T-104, not the T-103
This is because the T-103 clock motor is 120V, and requires additional neutral wire on terminal A
The T-104 clock motor is 240V, and requires only the two hot wires and does not require a neutral.

I suggest you exchange timers and get the T-104
Or run another wire to nearby 120V receptacle and connect Terminal A to the white wires in nearby receptacles. This will give you the neutral that is needed for the clock.
In the absence of a Neutral wire, you can work-around by connecting ground wire to Terminal A >>> but this is NOT Code. You might use the ground wire as a temporary work-around until running additional neutral wire.
