Question Bathroom Circuit

Hi everyone!

I have the following situation in my bathroom:

1. In the switch box, I have a 12-2 (black and white) coming from the breaker and another 12-2 going to the light and fan.

2. The white wires are bound together with a wire nut and the black wires are attached to the switch.

3. When you flip the switch, the fan and lights come on.

How can I wire things so that the fan is controlled by a separate switch? Thanks!

You need to replace the wire from the switch to the fan/light with 12-3 wire. You then need to add a second switch.

The 12-3 wire will have a black, a red and a white insulated wire plus a bare ground wire.

The second switch can be a normal sized switch (means changing the box to a larger box) or you could replace the regular switch with a duplex switch.

You wire it so that the red wire to the fan/light is switched by one switch and that black wire to the fan light is switched by the other switch. At the fan/light you connect the black to the fan and the red to the light (or vice-versa).

The white wire and the ground wire remains as they are. The white goes all the way through connected to each other at the switch and then connected to the fan/light, and the grounds connect to each other, to the switch(es), to the fan/light and to every box that is metal.

Or you can buy a Hunter 27186 (about $40) and use the wiring you already have in place.
