Question about Intermatic Hardware & Accessories

1 Answer

I have an Intermatic Timer T103 in a newly purchased home. It worked properly, now when the unit is on and then tripped off by the timer and off tripper, it does not keep time. The yellow time dial stays in the last position where it was tripped off. I'm pretty sure the wiring is correct, as the timer worked properly when we first bought the house. Thanks in advance!

SOURCE: wiring a wh40 intermatic timer to a sears hot water heater

Shut off breaker to you water heater. STILL TEST FOR VOLTAGE BEFORE YOU TOUCH ANY WIRING. The 3 wire that go to you water heater disconnect them. You are going to install them to your WH 40 timer.
The wires that you disconnected will now go to terminals: Black to Terminal 1 & White To Terminal 3, The Ground copper wire will go to the ground terminal should be a green screw.
You will have to buy some 10/2 wiring to go from your timer to your water heater. You can buy it by the foot at Lowes. Figure how much you will need.
With the new 10/2 wire install the Black to terminal 2 & White To Terminal 4, the ground wire will go to the ground screw with the other ground wire.
Wiring that went to terminals 2 & 4 will be installed to you water heater, the same way when you disconnected them. Set your timer clock and your done. Turn breaker back on!

Intermittent Intermatic Pool Timer T40003RT3 The pool timer is 220v but only one 110v 20amp breaker in the breaker box to the pool equipment and when it is off the pump will not run in manual mode.

http://waterheatertimer.org/Intermatic-control-centers-and-manuals.html#RT3

RT3 series has T104 240 volt timer -or- T103 120 volt timer, -plus- low voltage transformer for pool light.
The circuit breaker can be used for transformer, or another outlet or nearby light etc, or it can be used for a T103 120 volt timer.
To trace the wire back to breaker box.... open you main panel and start turning off breakers one at a time and label the panel.
See if you have single breaker or double breaker supplying power to pool equipment.

I just purchased a home that has an Intermatic T103 installed in the garage, how can I figure out want it's connected too?


T-103 is 120Volt timer that can be used to control 120Volt and/or 240Volt loads, for example pools and spas and outdoor lights.
Look at the yellow dial and see if it has trippers attached to dial.
If no trippers are on the dial, then the timer function is off.
Next look at dial and see if it rotates as time passes.
If dial does not rotate, then either the clock motor is bad or electricity to timer is off or timer is not connected to power.
Test across terminals A and 1 for 120Volts will tell if timer is getting power.
Last, move manual override back and forth and see if anything turns on and off.

I have Intermatic timer WG 1573 208/277V 60Hz 3W stamped on the case. I would like to chage this unit to a 110V timer system if possible. (In other words just be able to switch clock motors) If this is...


WG1573 is a 240 Volt clock motor for T100 series timers.
This means you have T-104 timer.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
Image shown on link above is T104R outdoor timer.
T104 indoor timer is the same except door does not have rubber gasket.
Terminals are labeled A 1 2 3 4
If this is not your timer, then add a comment.

Following instructions will convert T104 240V timer to T103 120V timer

Clock motor can be replace with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search

Timer mechanism snaps out and clock motor is located on back.
Remove clock motor with star screwdriver tip

Connect new clock motor wires to DIFFERENT terminals than before.
Old clock was connected to terminals 1 and 3
New 120V clock motor is connected to terminals A and 1

Wiring for 120V T103 is shown on link below.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
White neutral wire must connect to terminal A
Black hot wire must connect to terminal 1

The Timer trip switch works some of the time for the on time. Is there a better Trip switch with a longer tang for the T104. Thanks


You posted under Intermatic timers.

Grainger sells new Intermatic trippers:
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

Trippers push a lever on-and-off.
When tripper wears down, the lever is not pushed.

To check if tripper needs to be replaced, click manual override lever.
If manual override clicks crisp and clean, and load turns on-and-off, then timer is probably good shape.

Circuit breaker keeps tripping when timer turns on. Also, if turned on manually.Intermatic T103. I've had this timer for about a year and everything was fine until now.


Since the timer doesn't trip the breaker until it turns on the load, the circuit is OK up to and including the timer. Either the load is faulty (has a short) or the wire supplying the load is damaged. You can test the wire that supplies the load by disconnecting the load then turning the manual switch to ON. If the breaker doesn't trip, then you know it is the load itself that is causing the problem.
