How do I wire 14/2 cable to 14/3 cable for a hunter bath exhaust fan/light combo and a switch for each?

I will be pulling power off of the 14/2 cable in the attic above the bath on the same circut (end of run that powers a vanity light, switch and recepticle in bath. I'm assuming I will need to mount a junction box - have the 14/2 power coming into the box then from there 14/3 to the fan then 14/3 down the wall to a new dual switch.How do I wire 14/2 cable to 14/3 cable for a hunter bath exhaust fan/light combo and a switch for each?
Your 14/2 has one nuetral and one hot wire (usually nuetral is white)


If you now need two sources of power connect the 14/3 white to 14/2 white (this carries the nuetral)


Connect the red and black from the 14/3 to the black of the 14/2


this gives you two lines of 120v each (it will not give you 240)


use one line for light

That idea will work, however if you don't keep up with your colors in the j-box, you will have a mess...Easy fix...





Unswitched 14/2 from the hot source down to switchbox in wall. 14/3 from switchbox up to fan.


Connect both white wires together in switchbox. Black in the 14/2 will feed both switches hot..black and red in 14/3 to fan..black to fan lead, red to light lead, white from switchbox to 2 whites in fan.





This will also make troubleshooting easier, because you won't have to root around in j-boxes in the ceiling..
connect the white in the 14/3 to the new switch box to the common side of your fan/light switch and the other end of the white to the existing black hot 14/2 in the junction box it your attic. then use the red and black wires from the new switch for power to the fan/light. from the existing junction box pick the neutral (white) back up with the 14/3 to the fan/light.


basically you need two pieces of 14/3, one from the existing junction box to the fan/light switch and the second from the existing junction box to the new fan/light.


a ground fault interrupter is required if you are putting a receptacle within 4 feet of a faucet, sink or some other source of water and in wet/damp locations
I agree with the assesment by Donie. Additionally, if this light/fan is going to be located above the bath you need to put it on a GFC (ground fault circuit) There are two ways of doing this:





1. Replace the breaker in the breaker box with GFI breaker or...


2. Run the wiring to the fan/light switches from a GFCI receptacle.





Be Careful, Electricity is no joke.
In a bathroom and kitchen where you have water and faucets it is very important that electric outlets, switches and fixtures be grounded. The 14/2 wire is not going to provide a ground. You might wish to connect the bare third wire in the 14/3 to a water pipe or something even if you have to run another piece of plain copper wire to accomplish this.
