Install Wiring For Ceiling Fans & Lights

Use the ceiling fan and light kit to replace an existing light fixture for the easiest installation.


Installing a ceiling fan with modern ceiling fan and light kits can take anywhere from a few minutes to a few hours. The time depends on the type of construction you have in your home. For example, if you are replacing an old fan, the installation is simple because the necessary cables and holes are already in place. Regardless of the conditions, wiring the ceiling fan and lights to work properly is the easiest part of the process. In most cases, you will use the ceiling fan and light kit to replace an existing light fixture.


Instructions


1. Turn off the electricity at the main panel. Turn off the power to the entire home to ensure that the power is indeed off.


2. Remove the old light fixture. Many light fixtures have a cover that can be removed with a thumbscrew or screwdriver. The fixture itself may then be removed by unscrewing the mounting screws. Disconnect the light fixture cables from the power cables coming from the ceiling. This usually involves twisting the wire nuts connecting each set of cables counterclockwise. Set the old light fixture aside.


3. Mount the ceiling fan components. Follow the manufacturer's instructions to mount the mounting bracket, or base plate, and hook. Each model is slightly different, but most require you to fasten the mounting bracket to the ceiling beam nearest the location of the old light fixture with the provided mounting screws.


4. Hang the motor assembly, without the blades attached, from the ceiling hanger.


5. Strip 1 inch of insulation from the fan cables with the wire strippers.


6. Splice the fan cables to the power cables in the ceiling junction box. All fan and light kits have 3 cables and a ground wire. The black and white cables are the hot and neutral cables, respectively. The green cable is the ground wire. The light cable is usually red, black and white, or blue. Insert the stripped end of the fan's white cable and the white cable from the ceiling into a wire nut and twist the nut clockwise to splice the cables together. Repeat this process with the green fan cable and the green or bare copper cable from the ceiling.


7. Determine which type of switch combination the room features. Some newer homes are prewired with a double switch to control a light and a fan separately. Older homes may have a single switch to toggle both on and off at the same time. The former has an extra wire, usually red, coming from the ceiling junction box. The latter has a single black cable.


8. Connect the remaining fan wires. In a double-switch configuration, splice the black wires from the fan kit and the ceiling together with a wire nut as described previously. Repeat the process to splice the red ceiling cable to the light cable in the fan kit. Tuck the wires into the junction box.


9. Follow the manufacturer's instructions to finish the fan installation. Secure the mounting plate to the ceiling with the mounting screws. Attach the fan blades with the screws included with the kit.


10. Turn on the electricity at the main panel. Use the switches to control the fan and light.
