The wiring diagram for a 120 volt well pump pressure switch is a important part of any well pump installation. If you don’t understand the wiring of the switch, it can be a source of confusion and frustration. In this article, we will explain what you need to know about wiring a pressure switch and provide a diagram to help you get started.
What is a Pressure Switch?
A pressure switch is a device that senses the pressure of the water in a well and then turns the pump on or off. When the pressure in the well drops below a certain level, the switch will activate and turn the pump on. When the pressure in the well rises above a certain level, the switch will deactivate and turn the pump off. Pressure switches are designed to prevent water from being over-pumped, which can cause damage to the pump and the well.
How do You Wire a Pressure Switch?
Wiring a pressure switch is relatively straightforward but it is important to get it right. The first step is to connect the wires from the pump to the switch. Most pressure switches have two terminals, one for the pump power and one for the pressure switch power. After you have connected the wires from the pump and the switch, you need to connect the wires from the switch to the power source. This is usually done by connecting the wires to the circuit breaker or the fuse box.
How to Read a 120 Volt Well Pump Pressure Switch Wiring Diagram?
Once you have connected the wires to the switch, you need to read the wiring diagram to understand how the switch works. A 120 volt well pump pressure switch wiring diagram will typically have four wires coming out of the switch. The two black wires are for the pump power and the two red wires are for the pressure switch power. The diagram will also indicate which wires need to be connected to the circuit breaker or the fuse box.
Conclusion
Understanding the wiring of a 120 volt well pump pressure switch is an important part of the installation process. By following the wiring diagram and making sure that all the connections are secure, you can ensure that your well pump pressure switch will work properly and provide you with years of reliable service.
