Troubleshooting Signals and Indicators. Terminal Common Label Typical Wire Color Function 1 Power In / Line Black or Red Connected to the breaker panel hot wire 2 Pump / Load Red or Blue Connected to the pump motor 3 Ground Bare or Green Connected to the system ground for safety Step-by-Step Wiring Procedure Before touching any wires, ensure the circuit breaker controlling the pump is turned off and verify the power is dead with a non-contact voltage tester.
Standard Wiring Conventions for Pressure Switch Systems
This small device acts as the automatic brain of your pump, telling it when to start and stop based on the demand for water in your home. You will typically find three key terminals on the switch: the terminal for the incoming live power, the terminal for the pump motor, and the ground.
To visualize this, refer to the table below outlining the common conventions for standard systems. How a Pressure Switch Works At its core, a water pump pressure switch is a mechanical and electrical device that monitors the line pressure of your water system.
Standard Wiring Conventions for Pressure Switch Terminals
Connect the black or red wire from the electrical panel to the power terminal on the switch, securing it with the terminal screw. Once the system reaches the high-pressure setting, usually around 40 to 60 PSI, the diaphragm expands and opens the contacts, cutting power until the next demand.
