It is a hot wire that comes from the ceiling and hooked up to a wall switch.
Ceiling fan electrical connection red wire.
Sheathed cable with a red.
The red color on fans is for powering the lights.
A ceiling fan with a light fixture usually has two separate circuits one for the fan and one for the lights.
When there is an extra hot wire it is red.
Ground wires are either left bare or covered with green insulation.
Whether you are looking to wire a ceiling fan with lights to one power switch or add a fan in a room without a switch source this guide will teach you how to wire a ceiling fan using four common scenarios and the best wiring methods.
This wire is commonly red or blue but almost always has a tag on the wire that reads light.
In other words it is the primary connection that provides current from the switch to the fan s electrical load or motor.
Line up your ceiling fan bracket with the holes in the electrical box that s in your ceiling.
This may not represent exactly your wiring scenario and that can only be full understood using a voltage tester.
A ceiling fan usually consists of two main parts.
You may come across a red wire when wiring a ceiling fan with 4 wires.
The red or striped wire is the hot wire for the lighting fixture of the ceiling fan so if your ceiling fan does not have a lighting fixture it will only have the three other wires mentioned in the following sections.
Screw the ceiling fan bracket into the ceiling.
Thread the wires coming out of your ceiling through the center of the bracket so that they hang freely below it.
A red wire up in the ceiling fan junction box usually indicates that the wiring has been installed which provides separate switch for the light and a separate switch for the fan motor.
Each of these has a black hot wire and each should also have a white neutral wire and a bare ground wire although there may be only one common neutral and one common ground to serve both circuits.
Typically a ceiling fan is wired so the fan motor has power all the time by the black wire and the light of the ceiling fan is controlled by the wall switch through the red wire.
Wiring ceiling fans can seem complicated but the task really just depends on the type of fan you are installing and how you want it to operate.
Some sheathed cable includes a fourth red wire which makes it useful for wiring fixtures with three way switches or a ceiling fan with separate light and fan switches.
In rare instances the kit may include a red and yellow wire instead.
Finally connect the red wire from the electrical box to the remaining wire from the ceiling fan.
If your ceiling fan does not have a light fixture then simply cap off the red wire and attach the fan motor to the black wire.
Ceiling fixtures almost always have a black and white wire.
