    Question on how to connect two switches in a bathroom circuit, where one switch is for the fan, and one is for a light:

    20 amp circuit on 12G comes into bathroom, into a GFCI. I then run the GFCI to a single-pole switch in a 2 gang box which is then connected to a ceiling fan. The second switch in the box is for a light over the sink.

    How do I connect the first switch to the second, i.e. do I daisy chain them together somehow? Or should I have run two separate lengths of 12G romex from the GFCI to each of the two switches, and then connect each switch to it's respective load? I assume in this second scenario I need to use wire nuts to connect the white and black wires to a third piece of same that is then attached to the terminal screw on the GFCI?

    I can't find this particular scenario anywhere else online or in my basic wiring books.

    Thanks.

    Place 2 black pigtails on the 12awg NM black feeder and connect each pigtail to the bottom of the switch with the singlel pole switches in the upright position.

    Thank-you. I assume that I also pigtail all the neutral ends (12G feeder, fan, light) together, and then does it matter which switch I place the grounded wires to?

    switch

    If they both have grounding terminals then both of them.

    No, the white actually called the "grounded conductor" wires will all be wire nutted together, no pigtail needed. Then you place each black that feeds the fixtures to the top terminal (off/on upright) of your single pole switches.

    One for the light and one for the fan.

    Remove all power before you do this.

    The bare wires actually known and the "grounding conductors" will be pigtailed to each device (switch) and bonded to the box if it is metal.
