SOURCE: Bought an Intermatic T104 Timer for a 120v pool

T104 series intermatic timers are 208/230/277 volt clocks, not 120. I believe you have the wrong model and need a T101 series instead.

SOURCE: T101 R Clock will not turn

The "Line" is the power source. The "load" is the device that is being powered.

typically the green wire is the ground wire. I strongly urge you to verify your assumption that is is the common wire. If the green is indeed the ground, and it gets hooked up to common, you will be energizing the cabinet of the unit and posing a serious shock hazzard.

Your curcuit will be as follows.

The power source "Line" will have wires going to the timer. (hooked to the "line" terminals on the timer.)the timer then is supplying the power to the pool pump, and we will reffer to it as the "line".

The two black wires from the pump would be hooked up to the "load" side of the timer.

Typically they would be labled line 1 and line 2 or "L1" and "L2"

If yours are not labled so, describe exactly what terminals you have in detail in both the pump and the timer.

SOURCE: WH40 water heater timer: Does black wire from

WH40 is 240Volt timer.
WH40 will not work with 120V circuit.

See WH40 wiring illustration at following link:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html

There are two hot wires in 240V circuit because every circuit requires two wires to complete the circuit.
Hot wires from breaker connect to terminal 1 and 3.
Notice that small white wires are also connected to terminals 1 and 3.
Small white wires power clock motor located on back of mechanism, so this says power from breaker box must arrive on terminals 1 and 3. This insures that clock motor runs continuously.
If clock motor only runs when manual override switch is clicked ON, then your Hot and Load wires are reversed.

Bare ground wire connects to green ground screw.
Wires going to Load (water heater) connect to terminals 2 and 4.

FYI: Terminal A is not used unless circuit also has a Neutral wire,
See basic water heater circuit Diagram #2:
http://waterheatertimer.org/240-v-water-heater-circuit.html

Terminal A is also used if you want to convert WH40 to 120V timer by replacing 240V clock with 120V clock.

SOURCE: WOODS 59018 TIMER WIREING CORRECT

I don't have answer for defective timer. Buy another timer if everything below checks out:
59018 7-day timer has limited 1 year warranty, and appears to be made by Tork
Timer is for 120Volt single-pole only.
Rated for 1000 watt tungsten, 8A ballast, 1/4 HP
Push reset button with toothpick > not necessary to press-and-hold other button to accomplish reset.
After reset, 12:00 am Monday should display.
Programs are deleted. Reprogram timer.

To check, change and delete specific programming, press PROG key until selected program displays, and then set new programming >>> or press-and-hold MODE button and press PROG button again to delete selected program.

Timer has non-replaceable 30-day carryover battery and does not lose programming after power outage, and will retain programs until battery is depleted.

Review wiring:
Hot to timer black.
Neutral to timer white.
Load to timer red.
Ground to timer green.

Lights will blink if timer red and timer white are connected to load together.
Timer will not function if timer black and red wires are reversed. Display will not show.

2red wire and one green going to switch, need to hook up timer gm40av which wires go where


GM40AV automatically detects line voltage. So there are NO dip switches. Timer handles 120V thru 277V, including 208V and 240V.
Probably both red wires connect to terminals L1 L2. And this will power the timer clock. Green goes to green ground screw.
Wiring for GE40 and GM40AV is identical, except no dip switches for GM40AV
http://waterheatertimer.org/How-to-wire-GM40-timer.html
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM
GM40 series timers are very versatile and can be wired many different ways, including 3-phase applications, multiple loads with different voltages etc. Add comment and describe what you are wiring, and attach photo if needed, and I can go step by step.

Line voltage is not known.
240Volts has 2 hot wires and no neutral wire.
If both 10-2 wires test hot to ground, then you are working with 240V and no neutral is present.
http://waterheatertimer.org/240-v-water-heater-circuit.html#120-240

ET104C timer is shipped default setting for 240Volts.
ET104C can be wired many different ways.
Terminals 1 and 2 are for running the timer operation. So power lines connect to terminals 1 and 2.
Terminals 3 4 5 6 are dry. They have no power when wires are connected to terminals 1 and 2.
Typical 240v ET104C wiring shows next image.

Check that your pool heater supports optional fireman's switch
Black wires on firemans switch connect to pool heater. Power to fireman switch comes from pool equipment and not the timer.
If pool equipment does not support fireman, then cap off the wires.

Fireman switch turns off heater 15-20 minutes before turning off pump.
The purpose is so pool equipment lasts longer.

You can buy the fireman's switch separately, but if this is new timer, then switch is probably good.
Open following link to identify fireman's switch and related parts for the timer:

You might have your Line and Load wires reversed.
Line wires come from circuit breaker.
Load wires go to water heater.
http://waterheatertimer.org/B220C.html

WH21 wiring: There are 2 Hot Line wires coming from breaker box that connect to terminals 1 and 2.
WH21 is SPST and turns off one Hot wire going to Load. So Load wires connect to terminals 2 and 3. Terminal 2 has 2 wires: 1 Line wire and 1 Load wire.
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/wh21%20-%20english.ashx

Keep in mind that WH21 is 25 amp, 2Hp 240Volt timer that will work on water heaters up to 4500 watts. Look at label on side of tank to see wattage. All appliances and motors have labels.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

Larger wattage water heaters require 30 amp water heater timers as shown following page:

I have a Et 70115C Intermatic Timer, I want to install it on my Hot Water Heater, I have connected the 2 110V leads from my breaker to Terminals 1 & 2 and connected the two leads from the hot water...


A) 5 terminal ET70115C.
Voltage selector set to 240.

B) BUT you say you have 120Volts from breaker >>> confusing, so I'm proceeding on basis that you meant to say 240V from breaker.
Add a comment at any time.

C) Review timer:
5-terminal ET70115 timer has NO and NC terminals
NC is normally closed >> this terminal has power when timer is OFF
NO is normally open >> this terminals has power when timer turns ON
For water heater, you want NO terminal 4 so water heater turns ON when timer turns ON

D) Wire for 240Volt water heater

Two hot wires from breaker connect to terminals 1 and 2. This powers timer clock.
Jumper wire connects between terminal 2 to terminal 3. This sends power to the switch circuit.
Wires to water heater connect to terminals 1 and 4

E) 5-terminal timer turns off 1 hot wire to 240V water heater.
Turning off 1 hot wire will stop 240V circuit from working; Water heater thermostats also turn off one hot wire.
240V water heater has black and red wire.
Wire from terminal 4 should connect to Black wire on water heater.

Diagram shows two wires on terminal 1
Two wires on terminal 2
One jumper wire on terminal 3
One wire on terminal 4
Zero wires on terminal 5

My EH40 is not supplying power to the water heater. I hooked the power line in to posts 1 and 2 and I hooked the load out to posts 4 and 6. When I use my power checker it reads no power to posts 3,4,5,...


I have an EH 40 sitting in front of me right now.
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html
The link above shows correct 240V water heater timer wiring for EH40
Link below shows an overview picture of EH 40 connected to 240V water heater
http://waterheatertimer.org/images/EH40-water-heater-circuit-5.jpg
http://waterheatertimer.org/240-v-water-heater-circuit.html


EH40 has a 240V clock.
Terminals 1 and 2 send power to the 240V clock
Power to the clock terminals do not pass through timer to any other terminal

How to wire EH40 for 240V
240V line has 2 hot wires from breaker box.
Lets call these wires Hot1 and Hot2
These wire are interchangeable on 240V circuit
Hot1 connects to terminal 1 with a jumper to terminal 3 (or connect to 3 and jumper to 1)
Hot2 connects to terminal 2 with a jumper to terminal 5 (or connect to 5 and jumper to 2)

240V circuit has 2 wires going to the Load
Let's call these Load1 and Load2
These wires are interchangeable on 240V circuit
Load1 connects to terminal 4
Load2 connects to terminal 6

If the timer is still not working, go back to the breaker and test if it is delivering 240V to the circuit.
If breaker is bad on one leg, then the circuit can test with live power, but the 240V appliance will not work.
240V circuit requires both legs of 240V before circuit is complete.

After hooking up line wires to motor and load wires from water heater to load terminals,diasgram shows jumper wires from terminbal 1 to terminal 3 and terminbal 2 to tertmninal 5. voltage is 240.thank you ...


That is correct.

LINE 1 (incoming hot wire from source or circuit breaker) connects to terminal #1 then jumps over to terminal #3 using the _same_ gauge wire.

LINE 2 (other incoming hot wire from source or circuit breaker) connects to terminal #2 then jumps over to terminal #5.

The LOAD (outgoing to water heater) then connects to terminals 4 and 6.
