A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.

What size breaker does it take to run a outdoor well?

Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.


What size circuit breaker to use on well pump?

Depends entirely on the voltage and current rating of your pump.


What size amp circuit breaker should be used for a well?

Usually 30 Amp 240 volts, but there will be a spec on the well pump.


Can a 220 Volt well motor be added to a 200 amp box or does it need its own box?

The well pump breaker is installed in two slots in your breaker box. You then run the correct size cable for the amperage of the pump to the area where the pressure tank is located. install a breaker or disconnect on the wall near the pressure tank and then connect the low pressure switch to the disconnect. Connect the pump to the low pressure switch.


Do i need to switch circuit breaker since i went from 115V well pump to 230V well pump it is also a higher HP pump but pressure is lower than before?

The 230v breaker is 2-pole, The 115v is only single-pole so YES you need a new breaker. DON'T use 2 single-pole breakers instead. The well pump will run to the pressure setting of the pressure switch controlling it, regardless of HP. The difference might be in the size of the pump in flow rating, I.E. a 1/2 HP pump rated at 10gpm @ 70 psi won't perform the same as a 3/4 HP pump rated at 20 gpm @ 50 psi. Check the pump curve and pressure switch setting. The pressure switch for the new pump will need both power leads connected to the switch (1 lead per contact set), not 1 wire as the 115v motor was.


What type of circuit has double 20amp breaker going to a separate box at that separate box there is a well pump with another 20amp breaker to that?

Sounds like a 240 volt sub panel feeding a well pump.


How much electricity does a well pump use?

That depends on the depth of the water in the well and the size of the pump.


Which kind of well dose not need a pump?

An artesian well does not need a pump, as the water comes to the surface.


What size circuit breaker is needed for a 300 watt bulb?

A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.


What kind of well does not need a pump?

Artesian well


How do you run a 120V outlet off a 240V water well breaker?

You will need to have a three wire feeding your well pump motor to do this. It will be connected like a sub panel breaker box. A new breaker for the pump out of the new panel and a 15 amp breaker for the new receptacle. Both of these circuits must be protected by their own breaker. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
