I'm adding an exhaust fan (powered by the existing lighting circuit) to
a bathroom and want to change the single light switch to double switches
for fan and light. Is there any reason not to replace the existing 14/2
cable running to the switch box with a 14/3 to control light and fan
(code/safety/difficulty). It would be a lot easier to draw a single
replacement cable up through the existing holes/cavity than running a
second 14/2 down to the new double-gang box. (The wall switch is on the
outside wall of a sauna, so the wall is stuffed with insulation.) Thanks
for any advice.
