Ceiling Fan Wiring Diagrams

Dear Mr. Electrician: Where can I find ceiling fan wiring diagrams? Answer: Below are my own ceiling fan wiring diagrams.  In addition I have provided links to some ceiling fan manufacturers for replacement parts and internal ceiling fan wiring diagrams.  NOTE: Some links below go to applicable products on Amazon or EBay. The ceiling fan diagram at the top depicts a common wiring method that was used during the construction of houses long ago.  In this ceiling fan wiring diagram the wall switch controls the light on the ceiling fan and the pull chain switch on the fan controls the fan motor independently of the wall switch. It is not unusual to see a white wire being used as the hot or LINE wire on a switch.  However it is required that the white wire be re-identified with another color other than white, gray, or green.  I have rolls of different colors of electrical tape that I use for re-identification.  Some electricians will use a permanent marker to change the color of a wire. With the new construction of a home the National Electrical Code requires that a neutral conductor be installed at many wall switch electrical box locations.  Having the neutral gives you the option of using an electronic device instead of a standard wall switch to control your ceiling fan and light.  Read article 404.2(C) where the neutral is called the "Grounded circuit conductor". I have never seen wiring diagrams for a ceiling fan attached or printed on the fan housing or motor.  Most ceiling fan internal wiring diagrams are included with the installation instructions. I recommend that you read the manufacturer's installation instructions for your ceiling fan before you buy the fan.  They are usually available on the manufacturer's website.  Some ceiling fan manufacturer links are at the bottom of this post. The following ceiling fan wiring diagrams for wall switches can be used for new construction and old work remodeling and renovation. CEILING FAN WIRING DIAGRAMS The above ceiling fan wiring diagram depicts the power going into the switch electrical box first and then goes up to the ceiling electrical box on a two conductor cable.  With this method the fan and light are both controlled by the wall switch.  However the wall switch can be left on and the fan and light can be controlled separately using the pull chain switches on the fan. A remote control unit can be added to this ceiling fan.  The wall switch would just need to be kept in the on position. If you don't want a remote control, but would prefer to have all fan control options at the wall switch location, then you should search for a ceiling fan with a wall control that will operate over the existing wiring.  In some cases it is just a remote control that fits in the wall like a regular wall switch.  Casablanca Fan Company Intellitouch models have this feature. Above is shown the method that would be used to have a neutral conductor at the switch box from the power...
