As you know that we have two types of winding in a single phase motor and these coils have also two starting and finishing ends, So we connect one one end of each coils and make a common point which know also with name of common point. And the other ends called starting and running terminals or connection. So we have 3 wire terminals or wire which out form the motor , that's why we called this 3 wire motor.
In the post you will completely learn about single phase submersible pump control box wiring diagram, and this diagram not to hard to understand like there own diagram which is mostly available in control box back side.
Single phase submersible pump control box wiring diagram - 3 wire submersible pump wiring diagram
In submersible pump control box we use a capacitor, a resit able thermal overload and DPST switch (double pole single throw). The wiring connection of submersible pump control box is very simple. Here is the complete guide step by step.
- First of all switch of the main circuit breaker in your distribution board, this for that reason that you can work safely and protect himself form electric accidents.
- Then connect the supply to input wire connectors.
- After that get connection from wire connectors and then connect your neutral and Line wire (hot wire / phase) to the double pole single throw switch as i shown in the below diagram.
- Then get hot wire connection form DPST switch and connect to the reset able thermal overload protector. And form overload protector connect this (black wire) to one of the output wire connector.
- Now get your neutral wire (blue) form the switch and connect to capacitor, and form same terminal of capacitor connect it to one of the output connector.
- Then connect a wire form other free side of capacitor terminal and connect to the one of the out wire connectors which i shown with red or brown color in diagram.
- In 1 number connector connect your ground or earth wire as i shown in diagram with green color.
