This wiring arrangement allows for lowering the lights with a dimmer and controlling the fan with the built in pull chain.
Ceiling fan dimmer switch wiring diagram.
The source is at the ceiling outlet box and 3 wire cable runs from there to the switch box.
The hot source is connected directly to the bottom terminal on the switch.
Ceiling fan dimmer switch diagram.
This wiring method is used when the power source is from the switch and one wants to control the fan and light from that single switch.
This setup allows you to dim the light in the fixture and also switch the fan off and on from a separate switch.
The neutral from the source is spliced directly to the white wire on the fan kit and the cable.
Fan speed would need to be controlled by a pull chain or in some newer fans a wireless remote.
Ceiling fan capacitor connection diagram 3 wire ceiling fan capacitor diagram 5 wire ceiling fan capacitor diagram and installation role of capacitor in fan and single phase motor so in above diagram the speed switch contacts on l 3 and 2 5 uf and fan on running or start on 2 5 micro farad cap and on med speed.
From there two wires run to the ceiling fan.
Switched lines and neutral connect to a 3 wire cable that travels to the light fan outlet box in the ceiling the fan control switch usually connects to the black wire and the light kit switch to the red wire of the 3 way cable in this diagram the black wire of the ceiling fan is for the fan and the blue wire.
Line voltage enters the switch outlet box and the line wire connects to each switch.
