Guide to Electrical Wiring for a Well Pump
[ad#block]Electrical Question: My well is connected to a 220 volt circuit.
- 220 Volt Well Pump Power
I need a 110 volt outlet near the well house.
- Converting 220 to 110
Can I get 110 volts off of the 220 volt circuit wires for the well pump?
This electrical question came from: Randy, a Homeowner from Prosperity, South Carolina.
Thanks for your electrical repair question Randy.
Application: Installing a 120 volt or 220 volt circuit or modifying a well pump circuit..
Skill Level: Intermediate to Advanced, Best installed by a Licensed Electrical Contractor. Working in electrical panels is not recommended for homeowners, non-experienced individuals or non-electricians.
Tools Required: Basic Electricians Pouch Hand Tools.
Estimated Time: Depends on personal level experience, ability to work with tools and install 120 volt or 220 volt electrical circuit wiring.
Precaution: Identify the main circuit of the panel, turn it OFF and Tag it with a Note before working with the pump circuit wiring or installing the 220 volt wiring and circuit breaker.
Notice: Installing an additional 220 volt pump circuit should be done according to local and national electrical codes with a permit and be inspected.
Why You Should Consider a Sub-Panel for Your Well Pump Service
- 220v to 120v Converter
The only way to safely get 120 volts from a 220 volt circuit would be to use a transformer, however this would depend on what it is you wish to connect to the well circuit.
- Well Pump Circuit
The 220 volt well circuit is a dedicated circuit for the well pump and it is best to leave this circuit alone to prevent problems with the well pump.
Electrical Tips for Wiring a Well Pump
- Installing Well Pump Circuit Wiring
If a circuit is being installed out to a remote well pump, especially if there will be a pump house, I would encourage you to install a sub-panel with a 4-wire service.
- Pump House Sub Panel
The sub-panel service should be larger that the required circuit for the well pump. This way the sub-panel may provide a circuit for the well, and have additional capacity for lighting and freeze protection or other accessories.
- Planning for Future Equipment
Planning ahead for future electrical devices pays off in the long run, especially if the pump house is remotely located where a light and freeze tape will be required.

We have a 220 outlet in our pump house. We also have a broken 220 heater. We need to keep a small heat source in the well house during harsh winter nights where the temp outside drops below 32 degrees. Should we replace the broken heater? Or should we change the 220 outlet? Or do you have another suggestion? Thank you very much for your advice.
If the heater in the pump house is not working because there is a problem with the 220 outlet then the 220 outlet should be replaced with a new one. If the 220 heater is in fact broken then you do have a few options of replacing the heater or installing 220 volt self regulated heat tape or heat cable that is thermostatically controlled. The heat cable is always my recommendation because it will be safer and much more energy efficient. There are several manufacturers of heat cables available for this type of application, including Easy Heat, Raytheon, NuHeat and others. Your local well pump service company may be a good source for more information, and I’m sure they would be happy of take care of the installation for you and provide any additional service to keep your water pipes from freezing.
I hope this helps you,
