Wiring of a borehole submersible pump

In borehole submersible pump control wiring, the following terms typically refer to:

– L: This refers to the Line wire, which is the wire carrying the phase (or live) voltage from the electrical supply to the control panel.

– N: This refers to the Neutral wire, which is the wire carrying the zero voltage (or ground) back from the electrical supply to the control panel.

– C: This refers to the Capacitor wire, which is used in some submersible pump motors to start the motor.

– M: This refers to the Main winding wire, which is one of the wires of the submersible pump motor.

– A: This refers to the Auxiliary winding wire, which is another wire of the submersible pump motor and is used to help start the motor.

– PE: This refers to the Protective Earth wire, which is used to provide a safe path for electrical fault currents. It is connected to the metal casing or structure of the submersible pump.

It’s important to follow the correct wiring diagram when wiring a borehole submersible pump control to ensure it is done safely and accurately.
