How to wire a ceiling light with a wall switch.
Ceiling fan connection light wired to light switch fan on off with pull chain the wiring diagram above is for typical installation wiring light is switched the fan is powered by a pull chain once you have found and identified all of the wires on your fan and in your electrical box you can get to work on connecting them.
With single switch wiring power to the fan is controlled by a standard single pole wall switch like a regular light switch.
To do this method the wire from your wall circuit to your light has to have 3 wires.
Trace the electrical box for the switch and cut it out the same way as the mounting box.
The ceiling fan will have a black wire and another non white wire.
The wiring trick that lets you wire a ceiling fan with light to one switch.
Because the electrical code as of the 2011 nec update requires a neutral wire in most new switch boxes a 3 wire cable runs between the light and switch.
The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer remote control or other programmable switch.
Adding a wall switch to a ceiling fixture can be done in a matter of hours.
That second wire is usually blue or red.
The ceiling light fixture requires a neutral for the light to work and your wall switch box does not have a neutral wire available so additional wiring will be required to obtain the neutral wire from the outlet.
Connect the blue wire to the red wire.
If the wall is heavily insulated push conduit through the insulation and then feed wires or cable through the conduit.
Connect white wires together.
Connect black fan wire to the black ceiling wire.
Now for the trick.
Pick a single pole light switch for most applications.
Twist those two wires together then connect them to the black or red wire that came out of your.
Common applications include ceiling or hallway light switches a cellar or attic light a ceiling fan or chandelier or an outdoor patio light.
Split the incoming hot wire into a y and connect it to a terminal on each switch.
That s usually the hot wire for the light.
The biggest challenge is planning the cable route and running it from the fixture to the new wall switch position.
Cut out the traced hole with an oscillating saw.
Determine a location for the light switch.
In the switch box.
A single pole wall switch usually has a lever or toggle that completes the circuit when it is flipped up to turn a light device or appliance on.
