Let me see if I can help

Power coming in from the live circuit ( Main Power ) needs to connect to The A Terminal and #1 Terminal and the ground point.

Power connection out to the equipment you want times connects to the A terminal and then the #2 Terminal and then the same ground point.

The #1 and #2 Terminals are your break point switch, so when the timer is one power is applied to the #2 terminal, when off, no power to the #2 terminal.

Hope that helps some.

If the little gray box has no trippers, the dial does not rotate,and the lever is on, is electricity being conducted to my water heater?


Maybe yes.
Open TP valve on water heater and see if heater has hot water.

If you want to test, then test across wires on terminals 2 and 4 for 240Volt. Test across terminals 1 and 3 for 240Volt.

To fix timer, buy new WG1573 240Volt clock motor.

I NEEDAND CAN'T FIND DIAGRAM FOR THE INTERMATIC T101P201 FIREMAN SWICH


1) T101P201 timer does not have a separate manual yet
http://www.poolandspacontrols.com/products/mechanical%20time%20switches/pool%20and%20spa%20time%20switches.aspx

2) However typical T101P201 timer is ordinary T101 timing mechanism inside Nema 3R beige-colored outdoor plastic enclosure, with additional fireman's switch.
Wiring for T101 shows on following link, and shows on door of timer enclosure:
Check that your timer terminals match illustrations because many timers can fit inside Intermatic enclosures.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

3) Fireman switch wiring:
T101P201 has a fireman's switch that wires directly to the pool heater thermostat.
http://waterheatertimer.org/pdf/Intermatic-Firemans-switch-156T4042A.pdf
If you are not using the timer for pool heater, or if heater does not have connection for fireman's switch, then do not connect fireman switch wires, and just tape them out of the way.

I want to add an under-counter auxiliary water heater to my 15A dishwasher circuit. I need to install some sort of relay to cut out the water heater when the dishwasher is being run, to avoid overloading...


If I understand correctly you have 15 amp breaker with 14gauge wire.
Total watt capacity of 15 amp breaker is recommended at 80% rated load = 12 amps

You want to connect two appliances to same 15 amp line.
1) You have 6 amp Dishwasher that draws 720 Watts
2) You have under the counter water heater with 1500 Watt element that draws 12.5 amps.
3) Combined load is 18.5 Amps and 2220 Watts, approximately
So you do not want dishwasher and water heater turned on at same time.
Makes good sense.

Solutions:
> Easiest thing would be to put water heater on ordinary wall switch located inside sink cabinet.
Back when garbage disposals first came out, garbage disposal switch was inside sink cabinet. You opened cabine door and flipped the switch.
> Next solution would be to put water heater on a timer located under the sink. There are different timers. In-wall timers and box-type

In-wall timer would need relay/contactor
A battery operated timer like the ST01C would not need to be reset after power outage
http://waterheatertimer.org/Programmable.html
Here are instruction pages for selecting and installing the relay/contactor.
http://waterheatertimer.org/H230A.html
http://waterheatertimer.org/Install.html
Add a comment any time.

Box-type timer like T101 120Volt timer. This timer needs no relay/contactor.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101
Timer needs to be reset after power outage, but operates on ordinary 120V power, and is simple to install.

> There is no easy way to wire the dishwasher and water heater together so one is certain not to operate when other is turned on. There are likely electronic control panels for that project. But since you know the hours when dishwasher is likely to be ON, then set water heater timer to turn OFF during those hours. Water inside tank will stay hot for a couple hours, so there is no loss.

It sounds like you are a solid electrician.
If needed, add comment any time for more assistance.

Don't know what is it used for,and how it operates?I don't have any instructions for it.


You posted under T101 timer.
Most box timers have model number and instructions pasted on inside of door.
Instructions can seems a foreign language sometimes.

If your timer is different than T101, then add a comment with timer number.
I have extensive files on timers.

Box timers are generally used for heavy amperage loads like outdoor lights, swimming pool pumps, water heaters, parking lot lights and lighted outdoor signs.
They are surface mounted near breaker box, or in attic or basement, or garage.
Box timers are used in schools to ring bells, and inside factories to run processes and fans.
Some are complicated electronic devices used to control machines with one second precision.
Mechanical box timers are noisy when turning on-off, so are generally not installed in living area of house.

T101 timer is least complicated of any timer.
It is used for ordinary household 120V circuit.
Timer has 120Volt clock motor, and controls 120Volt circuit.
For example 120Volt water heater, or 120V grow lights, or aquarium, or any application up to 2 horsepower, for example timer can be located inside garage to control outdoor lights.
T101R is raintight outdoor box, with rubber gasket on door that seals tight when closed.
Raintight boxes are installed outdoors to operate 120Volt spas and pool pumps.
When box timer is rated for indoor, there is no rubber gasket on door, and that box is called NEMA 1 enclosure.
My local Lowes sells T101 T103 T104 > and each is for slightly different purpose and each wires differently.
Link below shows wiring and manuals for T100 series timers.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Here's how T100 series timer works:
Lift and rotate yellow dial until current time lines up with silver pointer.
Clock motor rotates dial as time passes.
Clock motors are accurate for years, but current time has to be reset after power outage.
ON-OFF trippers are placed on outer edge of dial.
Trippers push a lever, and lever turns circuit on-and-off.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Each time lever is pushed, manual-override lever clicks back and forth with audible sound.

I think I have My T101 time switch wired wrong I have nothing under terminal A ! side of my whit to terminial 1 and the other side of my white to terminal 2 which feeds my water heater and the blacks tied...


The timer that you have is a 120 volt timer. You are only breaking 1 leg of electricity which means in the off postion you still have 120 volts going to the heater. Also the clock will not function because you do not have a neutral going to the A terminal. You will need to replace time clock with a 240 volt clock T 104
