I have a switch loop that controls a bathroom light fixture. I would like to pull power from this switch (white wire is hot) to another switch that would control an exhaust fan. Can this be done and if so what would the wiring connections be?

Only if the light and fan come at the same time, best bet is to pull another switch loop for the fan.

How do you do pull a switch loop? I posted a similar question and just noticed your response and I think this is the solution I need.

First turn off the power!
A switch loop is very easy to add, Pull 1 12-2 w/ground from your fan, down the wall to your switch box.
Basicaly all you are doing is extending the black wire(hot), you have black and white power wires...and black and white in the switch loop...mark the white wire in the switch loop with black electrial tape on both ends. Wirenut the white power wire to the white wire on the fan, wirenut the black to the black in the switch loop. Wirenut the taped white wire to the black wire on the fan. Hook up your switch. You can get a stacked switch to put in place of the single switch, and not have to add a box.

I would like to post a correction in the reply by HP.. Acording to NEC the white wire in a switch loop should always be hot only to the switch and not the DEVICE,(light)..
Please correct me if I am mistaken...
