I am installing a Broan model# QTRE070C ceiling fan in my bathroom. I'd like to wire the fan through the GFCI plug to fan timer switch. The fan isn't going to be directly over the tub/shower enclosure but in the center of the bathroom ceiling. If it's not directly over the tub/shower will I still have to run it through a GFCI receptacle for power or can I get power to my switch from the existing light switch? I think it would be prudent to run through the GFCI. Could you explain to me how to wire my fan through the GFCI plug to a timer switch. (if pigtails are needed could you please explain how to do it too?) Thanks. PS. I'm in Canada 120 Vac, 20 amp cct. blk (hot), wh (neutral), ground.

The GFI has two sets of terminals, "Line" and "load". Line is for the power sourse. Load is for the other plugs, lights or fans you want protected. You can not, at any point cheat and wire the white wire back to the non-GFI white lines. This will immediately cause the circuit to break. Ditto for black,which would have course, render the GFI useless. When I doubted myself, I have tested to be sure I have done it right, I have connected bare wires from a lamp one lead to the black (GFI protected) wire and the other lead to an independent ground (not the GFI white). It should cause the GFI to break the circuit. You could do this with a wire, no lamp, but if you are wrong you will get a huge, dangerous spark. I am not an electrician, just a handyman, so someone please verify.
