Intermatic EI200 series is rated for 1/4 HP.
Check nameplate on motor for HP. Pool pump is probably 1 HP.

Add a comment and say what kind of timer you are using and say specifically what you want timer to do, and I will locate correct timer for that specific need.

You can also add a contactor to the circuit.
Timer controls contactor, and contactor turns pump on-off.

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.

Is timer the problem


I would think whatever is hooked up to the timer is bad. Not the timer itself. Disconnect/unplug the pool pump from the timer and see if the timer trips the breaker.

My pool pump trips main circuit breaker sometimes when it turns off


Get a new electrician! The pool pump should be on its own isolated circuit, usually on no larger than a 30 amp GFCI protected breaker. You said it was replaced but he only treated the symptom, not the cause. This one will take on site troubleshooting to find out why your whole house is affected.

Pool time switches pool on, but off does not trip off, and can't do it manual. When I push it on off, the pool pump tries to stop but continutes running. Have to use breaker box.


Model number of timer is not known.
Is this new installation? Or installation that worked before and recently stopped working?
If the manual override lever on timer does not turn Load on-off, then 1) wiring is wrong or 2) timer has gone bad or 3) pump has a short.
I suspect a short since you say the pump 'tries to stop running.'
Copy following links for troubleshoot walk-thru, and correct wiring:

Pool pump starts randomly (as if there is a short) even when it is not set to start and stop. Otherwise works fine, not sure if I need to replace unit or dissassemble and clean or ????? T21004R


Sounds like 240Volt WG1573 clock motor has gone bad and needs replacement. But more checking is needed.

You posted under T2100-4R which is 60 amp Intermatic control panel with a single T104M 240Volt timer mechanism.
All Intermatic timer mechanisms can fit into same control center, so you can possibly have different timer mechanism inserted into the T2100-4R control center.
The control center can have up to 4 circuit breakers.
Instruction manual shows that timer can also have fireman's switch that is wired to pool heater and causes pool heater to turn off 20 minutes before pool pump turns off.
http://www.poolandspacontrols.com/products/mechanical%20controls/60%20amp%20pool%20and%20spa%20control%20panels.aspx

(1) First thing: If you have T104 mechanism, do a troubleshoot run-down to see if trippers, clock motor, or wiring are suspect:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html

(2) Next would be to check the circuit breakers for loose wires, burned connections, or the smell of burning or crackling sound that says breaker is loose on the busbar.

(3) Check for loose wiring on T104 and test circuit:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
(a) Push the manual override lever to OFF position and test across terminals 1 and 2 and then across terminals 3 and 4 to make sure timer is turning off power to pump. Both tests should show 0 volts.
(b) Push manual override lever to to ON position and repeat test above. Both tests should show 240 volts.
If the test fails, then buy new T104M timer mechanism.

(4) If the T104 timer is turning off both lines in the 240Volt circuit, then pump cannot turn on since neither wire is Hot.
However if your T104 timer is actually a T101 timer or if timer has different wiring, where timer is turning off only 1 leg and not both legs of 240Volt circuit, then pump has one hot wire available and a short to ground could cause pump to turn on unexpectedly.

My pool sweep had been doing fine. Now the new pump seems to be dragging as if it is running on half power and the sweep crawls slowly. The pump gets hot and shuts off. The pool filter pump on the left...


My opinion is that new pump is defective.

You posted under Intermatic pool timer.
The timer will not have any effect on the new pump overheating.

Insufficient wiring can cause new pump to overheat.
However if wiring is undersized, and/or if both pumps are turned ON at same time, the circuit breaker would get hot and trip.

Instead of the breaker tripping, your new pump is getting hot, and turning off.
Remember, any pump that slows down and overheats is getting damaged.
Replace the defective pump.

Install a timer to control pool operation


Another option would be to get an electronic timer like the Intermatic P1353 that has 3 circuits on it that you could program to cut on and off at different times. For example, you could have one circuit that controls the pump and turns the pump on, then the second circuit would turn on the booster pump at a set time after the filter pump had come on and then the heater could be set to also run at a preset time after the pump circuit was activated. Since the pump, booster and heater are all 220, it's a straight forward hookup with everything in one timer box.

The lights, as stated before, would be on a separate circuit (110) and have its own timer or photosensitive eye set in line.

OK .. first check the breaker in the main electrical panel, make certain that it is retset, then the breakers in the pool disconnect, making sure they are reset and feeding power to the pump. Oh just so there is no confusion. when resetting a breaker, press firmly to off , then back to on .. if the timer will opperate the clock dial , then it should be good with turning on the pump.

Timer works fine. In on position, pool pump does not turn on


Most likely problems: The switch contacts in the timer are burned or, there is a loose connection or, the lever linkage is loose.

Need to turn off breaker and inspect for these potential failures.

More info, let me know...
