Question Wiring Exhaust Fan

I am installing an exhaust fan in my basement. Just fan no light and the fan has white/black/grd.

I have tapped into a porcelean light fixture with a pull chain and run power to my new box with white to white and black to black.

I assume that to wire a single pole switch that controls the fan that I will run Pw to Fw and Pb to switch and Fb to switch??

What if I wanted to install the switch with an outlet??

Thanks (total newbie........1st post!!!!)

The wiring you have described is a switch loop. It will work fine, but it would be impossible to add a receptacle to that setup. If you need the receptacle, you'll need to run 12/3 from the fan box to the switch box instead of 12/2. If you do that, you can use the black to feed power down to the switch and receptacle, red to feed switched power back, and white to provide the neutral that the receptacle will need.

If you decide to forgo the receptacle, then be sure to connect Pb to Sw, and Sb to Fb (not the other way around). Electrically it's the same either way, but the way I described conforms to code.

If this is in a bathroom (and you didn't say either way), then you should be aware that code has a lot of restrictions on bathroom receptacles, and your plan does not conform to them.

Also note that receptacles in bathrooms or unfinished areas of a basement must be GFCI protected.

No John, not in a bathroom and the basement is finished. Thanks for the info. I will likely run the 12/3 and put the outlet in. Gotta go to work so I will post back this evening. Thanks again.

Wiring Exhaust Fan

OK John, let me try this again.

I have an existing receptacle in the room, it runs from the last/only receptacle on the 20 amp circut. My power is here.

I want to wire the exhaust fan from this receptacle by adding a silent switch.

I am looking at this diagram (Fig. 1) http://www.nrha.org/howto/electric/wiring/ewiring.htm

Is this the ideal?
