Bathroom Fan Wiring Help

So far I have installed the 20 amp circuit in the electrical panel and connected to the GFCI line feed using Romex 12-2 wire.


I have run a Romex 12-2 wire from the gfci load feed that can go to either the fan itself or the switch. Not sure where it should go.


The fan junction box calls for the following connections:
Ground
Live to Black (night light)
Neutral to White
Live to black (regular light)
Neutral to white
Live to black (vent fan)


The switch has 5 total screws:
1 Ground
1 Common Line
3 side wire terminals.


I plan on using Romex 12-2 wire for all connections.


If somebody understands what I have above and can tell me where to connect the wires from the GFCI load feed and what connections need to be made between the fan and switch that would be great.


Thanks in advance.

 

Under 2011 NEC a neutral even if not used is required in the switch box so it is simpler to run power to the switch first.

You would need to either run 12-4 (not 12-2) from the switch to the fan or run ENT (flexable plastic conduit) with five #12 wires.

Note unless required by location such as over a shower or manufacturer instructions most say not to put a light on a GFCI because if it trips it leaves you in the dark. In this case since it is a fixture with a light come from the line side of the GFCI not load side unless otherwise contraindicated..
