Wiring diagram for GE Mechanical Time Switch model 56922

I have 3 wires (hot, neutral, and ground) coming in for the hot water heater but it's 240v but the GE Mechanical Time Switch 56922 wiring diagram shows 2 hot for the 240v wiring diagram. Can I use the 120v wiring diagram (for one in coming hot wire) as long as I set the jumpers to 240v Or do I need a different switch?

I have extensive files on timers and don't recognize that GE number.
Possibly you have GE 15071 or 70 or similar timer.

Open following link to identify timer, and read step-by-step wiring.

SOURCE: #15207 timer, Need to know

Normally, timers need to have a seperate power source for operations besides the power source it is controlling. Two posts should read "clock" for the timers power source. The other power source that is being controlled uses "line" for the incoming and "load" for the Hot water tank. Hope this helps.

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.

Proper wiring for 220 volts timer


You posted under T104 timer.
Open following links for wiring information and diagrams.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/B220C.html

You say 220Volts and I use 240Volts = same thing
T104 is 240Volt timer with 240V WG1573 clock motor
240Volt cable has two hot wires that arrive from breaker box. These wires connect to terminals 1 and 3.
240Volt cable going to Load has two wires. These wires connect to terminals 2 and 4.
Bare ground wire connects to green screw.

If your timer has terminal A, then terminal A is not used unless you are converting timer for 277Volt operation, or some other specific wiring purpose, or if your 240Volt cable from breaker box also has a Neutral wire, in which case the Neutral connects to terminal A.

If you have different brand timer, or different model number, then add a comment with model number that shows inside timer door, and I will search for wiring diagram.

You have 220Volts (same as 240V), then that circuit does not need a neutral.
All household single phase voltage requires two wires to complete the circuit.
With 120V, you have 1 hot wire and 1 neutral wire.
With 240, you have 2 hot wires, and these hot wires are called 'out of phase' since each comes from separate side of breaker box.
Notice that your 220V 10-2 wire goes back to a double breaker. This double breaker snaps over two different busbars. The breaker pulls 2 out of phase 120Volt lines, and when testing voltage across those two out of phase 120V wires, you get 240V potential.
The ground wire is redundant safety in both 120 or 240 Volt circuits, and is not necessary for either 120 or 240 to operate.

Lost wiring instructions for my woods water heater timer. What wires attach to bus bar


Timer model is usually located inside the door panel:

1) Open following link to access manual with wiring diagrams.
http://waterheatertimer.org/Woods-timers-and-manuals.html#Boxtype

2) Example manual shows different wiring diagrams:
http://waterheatertimer.org/pdf/Woods-59396-59399-manual.pdf
If you have timer with 8 terminals, and ordinary 240V water heater, then use diagram on bottom right.

3) Woods timers are wired identically to GE 15207, except your model might not have dip switches.
http://waterheatertimer.org/How-to-wire-GE-15207-timer.html

4) Busbar usually refers to a long metal bar where many wires connect to same pole. For example neutral busbar inside breaker box has 20 or 30 wires connected to it, and all are connected to Neutral wire from power pole.

How to wire a intermatic timer T104 240 v to a 120v?


T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/images/Back-of-WH40-2b.jpg

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
http://waterheatertimer.org/images/T-104-control-120V-Load-500.jpg
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
http://waterheatertimer.org/images/T-104-control-120V-Load-2-5.jpg
Replace T104 240V clock with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

WH40 water heater timer: Does black wire from service box go to terminal #1 and black wire to water heater to terminal #2? Does neutral (white) from service box go to terminal #3 and neutral (white) to...


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.

How to wire a GE timer switch, model 56922, to my 220v hot water heater, using 2-#10 awg with ground?


You should have received a booklet or manual for the timer unless you got it third party, used, etc.

Anyway, here's a link to the PDF manual for this timer:
http://www.jascoproducts.com/support/manual-downloads/applications/DocumentLibraryManager/upload/15087-15207-56922-Manual-eng.pdf

From what you described, it sounds like you want to wire the timer using a 240 volt, single phase wiring system.

First, download and print out the manual.

Make sure all power is off. Pay VERY close attention to the switch settings in the timer as to how to set them to run the timer motor on 240 volts. If you want to use 240 volts, then set the switches to the settings shown in the CENTER drawing or the one that's labeled 208~240VAC for the timer motor.

After you verify that, see the schematic in the manual that is located in the far bottom right-hand corner of the page and is labeled 208/240/277V Timer, 208/240/277V Load, Double Break wired as single throw.

The labels L1 and L2 mean the power coming into the timer. L1 and L2 should be one leg each of the power coming from a 240 volt circuit breaker in your power panel rated for the duty. The heater should be the only thing on the circuit. The little box on the right labeled Load means your hot water heater.

The ground wire (green) should be connected to the ground lug inside the heater connection box or secured to the metal part of the box. Attach and secure the other end to the timer case or mounting box which should also be grounded.

Set the timer trip switches where you want them.

Double-check all connections before applying power. Check the timer later to be sure it's running and keeping time.

If you are not comfortable performing this type of work, it would be dvisable to hire a competent electrician to do the work.
