The ceiling fan capacitor wiring is become easy if you know about start run and common connection in fan wires.
Crompton ceiling fan wire connection.
Connect the white wires neutral wires from your fan and ceiling together.
White wires found in the ceiling junction box are sometimes used for switching when a wall switch is used.
Lastly connect the blue wires together or the blue wire to the black wire for lights.
Typically these white wires are identified with black tape or a black marker.
As you know that ceiling fan have 3 wire which come out from winding.
Only 14 coils will be put at the bottom of 14 slots fan and 14 coils above.
The bottom winding that is inserted first in the ceiling fan is always called the starting winding and the top winding is called the running winding.
Connect the red and blue wire and put a wire nut and electric tap and insert it in the wire connector as shown in fig below.
Connect the green wire to your household ground wire copper bare wire.
But the problem is that which one for capacitor and which one for direct power supply.
Wiring connections for a ceiling fan may seem overwhelming when wiring to a wall switch for the fan motor and the light fixture but this should help you out.
Connect the black wires together.
Now connect the live and neutral to the power supply.
For ceiling fans without lights follow the same step.
Connect the white wire coming out of your ceiling to the white wire coming out of the top of the fan.
Twist the copper ends together until they are securely connected to each other.
In this wire we connect the electric power supply and capacitor.
Switch on the main circuit breaker to test the ceiling fan.
This is a simple illustrated circuit diagram of ceiling fan to be noted that the wiring diagram is for ac 220v single phase line with single phase ceiling fan motor.
Here a simple spst switch is used to supply power or not to the fan motor and a regulator is used to controlling the fan speed.
Connecting the neutral wires will complete the circuit in your fan.
