I need to add a gfi outlet to my wifes bathroom. I want to add it to the cu
rrent light switch box. This box currently has two switches, one for the fa
n,light and one for the vanity light. Each switch has a white wire, a black
wire, and a ground. When checking with a voltmeter, the white wire on both
switches always has power. Each black wire only has power when the switch
is turned on. I am assuming the white wire is the power wire. Can I take th
ese white wires off the switches, connect them to the top and bottom "hot"
terminal on the gfi outlet, then feed the switches from both terminals on t
he other side of the gfi? When I did this messing around with the switches,
everything worked properly. I just thought that the black wire was always
the constant power wire.
