Fan/Light Switched Together - Power Source at Light and 2 3-Way Switches with Power Required, 3-Wire plus Ground Cable Routed thru a Ceiling Box

At the ceiling box - the ungrounded fixture conductors {aka hot} for the fan and lights connect to the black wire coming from switch 2. The white wire from the circuit power source cable is the grounded leg conductor {aka neutral} for both the fan and light. The black wire from the switch 1 connects to the black wire from the circuit power supply cable.

Wrap a piece of black electrical tape around both ends of the white wire going between the 2 switch boxes as well as the portion of white on this cable being looped thru the fixture box, as this wire is also being used as an ungrounded conductor {aka hot}.

Bare wires are together and grounded to box (if metallic) and if the fixture has a green wire or a grounding screw , it gets grounded also. Bares and green wires are equipment grounding conductors.

Be sure to read all documentation that comes with your fan / light combo fixture.

If you need onward power from the fixture then....

(1) If only switched power required onward then at existing fixture...

1. onward cable - black/white/bare
2. connect black from onward cable to the black wire coming from switch 2.
3. connect white from onward cable to white wire of the circuit power supply cable.
4. connect bare from onward cable to bare coming from circuit power supply cable and to electrical box if metallic.
5. At the onward cables destination , the black is the switched ungrounded conductor {aka hot}, the white is the grounded leg {aka neutral}, and the bare is the equipment grounding conductor.

(2) If only unswitch power required onward then at existing fixture...

1. onward cable - black/white/bare
2. connect black from onward cable to black wire coming from circuit power source cable
3. connect white from onward cable to white coming from circuit power supply cable
4. connect bare from onward cable to bare coming from circuit power source cable and to electrical box if metallic.
5. At the onward cables destination, the black is the ungrounded conductor {aka hot}, the white is the grounded leg {aka neutral}, and the bare is the equipment grounding conductor.

(3) If switched and unswitched power required onward then at existing fixture...

1. onward cable - black/red/white/bare
2. connect black from onward cable to black wire coming from circuit power supply cable
3. connect red from onward cable to the black wire coming from switch 2.
4. connect white from onward cable to white coming from circuit power supply cable
5. connect bare from onward cable to bare coming from circuit power source cable and to electrical box if metallic.
6. At the onward cables destination, the black is the unswitched ungrounded conductor {aka hot}, red is the switched ungrounded and the bare is the equipment grounding conductor.

If you need onward power from the switch then....

This is not possible with this configuration as no grounded leg {aka neutral} exists at the switch locations.

If wiring multiple fixtures be sure to check the following guidelines concerning how to do it and what not to do: Wiring Multiple Fixtures.
