Ceiling fan wiring
I went to install a ceiling fan in the dining room, the builder installed nothing which is good because we are using it as my wifes office. I removed the cover plate and check power with the switch off and the wire coming from the switch had power. So I unhooked the wire from the switch and checked again and it still has power with both ends unhooked. So I checked the voltage and it read around 11 volts AC.

The only thing I can figure out is maybe a nail hit the wire(why isn't it 120 volts I don't know) The 11 or so volts isn't enough to light a light bulb, but will it do anything to the fan, maybe over time. Has or will this problem draw current and waste electricity.

I bought this house brand new in Feb of this year, there is a warranty on the house but If I can just wire the fan in and not worry about it I wouldn't have to wait until they come out to fix it.

The voltage you are reading (with a digital meter) is known as phantom voltage and will disappear as soon as a load is placed on the circuit. Check that same circuit with an analog meter or with a solenoid tester (Wiggy), there will be no voltage present.

Cool thanks, glad I hadn't called the builder yet, they would have laughed.

Fan is already in and works great!

Please tell me that the box was rated for fan support. Regular ceiling boxes are NOT suitable to support a ceiling fan.
