Tag: Two Switch Fan Light Control

Dear Mr. Electrician: Where can I find ceiling fan wiring diagrams showing the blue and black wire connections? Answer: Below are my ceiling fan wiring diagrams with two-switch diagrams further down.  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.  As an Amazon Associate, I earn from qualifying purchases.  Using my links helps to keep this website FREE. The ceiling fan wiring diagram at the top of this page depicts a standard wiring method used during the construction of houses long ago. In this ceiling fan wiring diagram, the blue wire on the ceiling fan is connected to the LOAD side of the wall switch to control the fan's light.  The black fan wire is connected to the LINE enabling the pull chain switch on the fan to control the fan motor independently of the wall switch. It is not unusual to see a white wire used as the hot or LINE wire on a switch.  However, the white wire must be re-identified with another color other than white, gray, or green.  I use rolls of different colors of electrical tape for re-identification.  Some electricians will use a permanent ink marker-type pen to change the color of a wire. With the construction of a new home, the National Electrical Code requires that a neutral conductor be installed at most wall switch electrical box locations.  The neutral lets you use 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."

Electrical Boxes Rated For Ceiling Fans Information To Help With Ceiling Fan Repair Links to Articles Depicting Ceiling Fan Installations 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 depicting the blue wire and the black wire are included with the installation instructions. I recommend 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. Top Of Page CEILING FAN DIAGRAMS The above ceiling fan wiring diagram depicts the power going into the switches' electrical box first. Then a switched hot and a neutral go up to the ceiling mounted electrical box on a two conductor cable.  This method connects the black wire for the fan motor and the blue wire for the ceiling fan light to the LOAD wire from the wall switch. The same wall switch controls the fan and light.  However, the wall switch can be left on, and the fan and light can be controlled separately...
