The Black hot wire from your house supply goes on the terminal below the L and 1.

The White neutral wire from your house supply goes to the terminal below the X.

Connect a White neutral wire from the terminal below the X to your neutral on your load.

Connect a Black wire from terminal #2 to the Black on your load.

This wires up both your timer clock and will turn on your device, too.

If you don't have an X or L1, send the question again with the model number of your timer.

Can i put 120 volts to the dry contacts on a tork dts400b timer?


1) DTS wiring shows on link below:
http://waterheatertimer.org/pdf/1TORK.DTS400A.DZS400A.WIRING.pdf
Timer appears on page below:
http://waterheatertimer.org/Tork-Digital-timers-and-manuals.html#DTS

2) Tork DTS400B is 4 channel timer, so you can control 4 different Loads with different programming for each Load.

3) I am not 100% certain what you are asking.
Timer can be wired for 120V operation.
Clock motor has separate wiring from Load wiring.

4) Clock motor is shown in wiring diagram as 'Timer supply'
Timer supply is on lower row of terminals.
120 Volt Hot connects to screw terminal identified as 120
120V Neutral connects to screw terminal identified as N
Clock motor wiring does not pass to the Load or channel terminals.

5) Load terminals are not fed by 120V connection to Timer supply.
Each load is wired separately.
For example lets say Load 1 is channel 1 or CH1.
Hot to CH1 connects to terminal C.
Neutral to CH1 connects to terminal NO, or to NC terminal.

6) Terminal NO normally open turns ON when timer turns ON
Terminals NC is normally closed is ON full time, except when timer tuns ON. So NC turns OFF when timer turns ON.

Can I use my Intermatic model T-103 switch for 2 separate 20amp 120v circuits?


Yes, the timer motor is 120 volt, so connect both neutrals from each separate 120 volt circuit to the "A" terminal. Probably best to place all the neutrals (line and load) under a wirenut with a jumper going to the "A" terminal. The terminals are intended for only two wires.
One hot will go to terminal #1 and the other will go to terminal #3. The 120 volt timer motor is connected internally at the factory to the "A" terminal and terminal #1.

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.

How do I wire an intermatic t-103 timer switch


The T-103 has a 120Volt clock motor

From there, the wiring can go two directions depending on your Load voltage (load is the fan, light or motor that timer turns on-off)

Here is a link that shows exact wiring:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103

When wiring the T-103, steps 1-2-3 are true for 120V or 240V installation:
1) A white Neutral wire is always connected to terminal A (Neutral wire connects to Neutral busbar in breaker box)
2) A black Hot wire is always connected to terminal 1 >> this hot wire can come from 120V or 240V breaker
3) Black wire going to Load (fan, light, motor) is always connected to terminal 2
The following step is true for 120V Load
4) if Load is 120V, then white wire from Load connects to terminal A
The following steps are true for 240V Load
5) Only the neutral wire connects to terminal A as described in (1
6) The second Black hot from breaker box (240V has 2 hot wires) connects to terminal 3
7) The second White going to Load connects to terminal 4

Here are 2 more links that show how 120V and 240V circuits are wired

How do you wire a intermatic t103


I'm looking at the T-103 sitting here in my office.
Terminals are labeled: A 1 2 3 4
I have about 10 different Intermatic timers on the shelves & each is a bit different

The T103 has a 120Volt (or 110V) clock motor
You need a white Neutral wire to operate the T103 clock

120V: Let's say your Load (light, fan, pump) is 120V
The white Neutral from breaker box connects to Terminal A
The 120V black Hot wire from breaker box connects to Terminal 1
The black wire going to Load (fan, light, motor) connects to terminal 2
The white wire going to Load connects to terminal A along with the Neutral
Ground wires connects to green ground screw
If your wires from breaker and wires to load are wired in reverse, the timer will turn ON the Load but the timer will not shut the circuit OFF.
To test which wire is Hot and Neutral, look at explanation at bottom of page.

240V: Let's say your Load is 240 Volts (or 220 Volts)
The clock motor is still 120V so you still need a white Neutral wire connected on Terminal A
Now you have 2 Hot wires coming from breaker box
Hot wire 1 from breaker box connects to Terminal 1
Hot wire 2 from breaker box connects to Terminal 3
Wire 1 going to Load connects to Terminal 2
Wire 2 going to Load connects to Terminal 4
Ground wires connects to green ground screw

What if you don't have a Neutral wire and you are wiring a 240V circuit?
240V circuits normally have 2 hots and a ground, but no neutral
Buy the T-104 timer
The T-104 has a 240V clock motor
Wiring for the T-104 is exactly the same as 240V wiring shown above for T103 EXCEPT there is no Neutral on Terminal A, and Terminal A is bare
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How to test which wire is Hot
Test requires wires with live electricity >>> this is not advisable without precaution
Stand on dry boards, do not touch anything metal, wear dry clothes, do not hold screwdriver in mouth, wear gloves, tape tester leads to wood sticks so hands are away from power
Remove wires from terminals
Separate wires so they can be tested
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire(s)
If circuit is 120V, then there is only one Hot wire
If circuit is 240V, then 2 wires will test hot to ground >> these wires will be Hots 1 & 2
Test assumes circuit breaker is functioning normally.

How do you test for neutral?
If you have 120V line with only 1 hot wire, then one of the white wires will be Neutral?
Test Hot wire to each white wire
Tester lights up on neutral

Let's review your wiring. There's probably something miswired when you get symptoms like that. Let's work one circuit at a time.

For circuit #1, the incoming (LINE) black (hot) wire is connected to the #3 terminal. The white (neutral) is connected to the "A" terminal. The bare equipment grounding wire is connected to the "GR" terminal (the green screw on the case).

The outgoing (LOAD) black wire to the first set of lights is connected to terminal #4 and the outgoing white (neutral) wire connects to the "A" terminal. The outgoing bare wire to the lights goes to the "GR" terminal. It's best to twist the wires together with a pigtail, wirenut them and connect the pigtail to the "GR" terminal.

Now for separate circuit #2. The incoming (LINE) black (hot) connects to terminal #1. The incoming white (neutral) connects to terminal "A". The incoming bare wire connects to the "GR" terminal.

The outgoing (LOAD) black wire to the 2nd set of lights connects to the #2 terminal. The outgoing white (neutral) goes to the "A" terminal. It's OK to twist all the white neutral wires (incoming _and_ outgoing for _both_ circuits) together with a pigtail that goes to the "A" terminal. Use a red wirenut.

As long as you don't load the 15 amp breaker over 12 amps (this is considered a continuous circuit and it cannot be loaded over 80% per NEC), you don't have to have two circuits if you don't want too. Figure about 1 amp per light as long as the lights aren't over 100 watt. (100 watt lamp/120 volts = 0.83 amps (round to one amp)

T103 clock not working


Please read all of this post. You may burn up the 120 volt T103 timer motor is you are not careful.

The statement: "I have 120v board with 120 constant and 240 timed" is not very clear to me as to what you mean.

In US residential wiring, the white wire is not always the "neutral;" The white wire is sometimes used for 240 volt circuits.

We cannot tell you how to wire your timer unless we know _exactly_ what you have.

If your incoming supply cable (from the breaker box) has 3 wires (black, white, and bare), there are two scenarios:

1...If the voltage from black (hot) to white (ALSO hot in this case) is 240 volts, and you have only 3 wires (black, white, and bare), then the T103 is the _wrong_ timer if you are trying to control a 240 volt load. You should use a T104 timer.

The T104 uses a 240 volt timer motor and the T103 uses a 120 volt timer motor.

2...If the voltage between black and white is 120 volts, then you will only be able to control 120 volt loads; then the incoming black supply wire is connected to terminal 3 and the white (neutral) wire is connected to the "A" terminal. The bare equipment grounding wire is then connected to the "GR" terminal.

To show the difference, if you are trying to control a 240 volt load, to use a T103 and wire it _correctly_, you would need to have a incoming supply cable with a total of 4 wires (black, red, white (neutral), and bare) Black to red would be 240 volts. Black to white would be 120 volts. Red to white would be 120 volts.
The connections would be as follows:
White (neutral in this case) to the "A" terminal
Black to terminal 1
Red to terminal 3
The 240 volt load would then connect to terminals 2 and 4
Both the bare equipment grounding wires are connected to the "GR" terminal.

Since you did not mention a red wire, I can only ASSUME that this is not the case.

Sorry, we can't tell you how to wire this timer based upon assumptions.

So, what do you have?

Clock doesn't work


The wiring diagram for that timer is somewhat misleading. The 120 volt clock timer motor is connected internally to the "A" (neutral) terminal and the #3 terminal. The "A" (neutral) terminal is to the immediate left of the #1 terminal.
Here's how to do the wiring for your use, (assuming a 120 volt supply circuit and a 120 volt lighting or other load):
Connect the incoming power (line) black wire to terminal # 3. Connect the incoming (neutral) white wire to terminal "A".
Connect the outgoing (load) black wire to terminal # 4.
Connect the outgoing (neutral) white wire to terminal "A".
