I have added a fan in my bathroom. I planned to wire it in parallel to the existing light, off of the existing light switch (in the hot,black wire,side of the light circuit). However, when I do this, only the light works, the fan will not run. If I wire them in series, only the fan will run, the light is dark. Clearly, there is something I do not understand, please help!

Hi hyper71.

So. You are trying to operate a fan in your bathroom.
You want this fan to be on separate sw.

To achieve this you need to have:

1. A feed in the sw. box. (a neutral & a hot + a neutral & a swicthed wire to lamp + ground)
2. If you have all this, you have to pull a cable ( black& white +ground) to fan.
3. You have to install 1 more box, ore use a stacked switch.


Regards Zoltan

P.S. If you have further problems Email me

hi hyper71,
sounds like u may have just switched power in the switch box (just a white black and a bare with the white and black hooked to the switch). if this is the caes the power is in the light. u can still hook up your fan useing the same switch what u need to do is bring your fan wire into the light box, and hooh up the bare to the other bares, the white to the white the is on the light and the black to the other wire on the light.
