Red Wire Circuit Diagram. Hopefully this will make it clearer as to what the wires at the ceiling rose are for. In this diagram the source is at sw1 and the hot is connected to the common terminal there.

The function of these wires is the same as we have mentioned above. Rpm signal red and.
Here the fan and light are controlled by the same switch and the dimmer is not used.
The ground wire also connects to the switch but the white wire gets spliced to the circuit neutral wire and bypasses the switch. In this diagram the source is at sw1 and the hot is connected to the common terminal there. Another is that the box is on a circuit three way switch loop. Connect and wrap the two remaining black wires in the box to create a path between the lamp and the second switch.
