How do you install a ceiling fan with black blue white and bare wires when the junction box on the ceiling has only a red and a white wire?

for USA, Canada and countries running a 60 Hz supply service.The red wire is hot. Connect your blue and black wires to it. Connect your white to white on your fan. Connect the bare wire to the ground screw on your box in the ceiling. SWITCH OFF THE POWER AT THE CIRCUIT BREAKER FIRST!


It is best to ask for a wiring diagram from the place you obtained the ceiling fan from.

If they say they have not got one, or the fan was not bought new, then maybe you can find out the manufacturer's name from a label on the fan or on the box it came in? If you have the manufacturer's name you may be able to find their web site, phone number or street address so you can ask them to send you a wiring diagram.

The usual 120 Volt household AC wiring colors are:

Black is a "Hot" or "Live" wire which may come direct from the main breaker panel so is always "on". (But sometimes this wire is the one coming from the on/off switch controlling the lighting fixture.)

Red is a "Hot" or "Live" wire which may come from the on/off switch controlling the lighting fixture. (But sometimes this may be the wire which comes direct from the main breaker panel so is always "on".)

White is a "Neutral" wire.

Green (or bare wire with no insulation) is the local "Ground "wire.

What the Blue wire does is not obvious from the question as asked and should be found out from the wiring diagram for the fan.

If you can't get a wiring diagram and you still can't work out what to do then you should ask someone who knows how to handle mains electricity safely to advise you.

Better still, for your own personal safety, have a licensed electrician install the ceiling fan for you.


It should be a black/white pair from the box in the ceiling: black is normally the "hot" and white is the "neutral". (Maybe in your case the "hot" is the red wire?)

One of the blue and black wires on the fan goes to the fan motor and the other maybe goes to an optional light in the fan housing? Before you connect them, you must check the wiring diagram or ask licensed electrician for his advice.

Only when you know for sure what they do, those blue and black wires should be connected to the the ceiling box. Often the black wire is the main "hot" wire on a fan unit.

The white wire on the fan connects to the white "neutral" wire in the box.

The bare (ground) wire on the fan must be connected to the ground wire in the ceiling box. Some wiring codes allow you to connect it to the white wire if there is no separate ground wire, but it is an unsafe method and it may be illegal to do this if your local wiring code does not allow it.



As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

Connect the green wire to the bare wire in the junction box. Connect the white wire to the white wire in the junction box. Connect the black blue wires to the black wire in the junction box. The black is usually the fan and the blue is usually the light on the fan. They seperate them in case you wish to hook the fan/light to two switches.

Just wire the fan color to color and wire nut the red wire it insulate it from shorting out in case it is hot.

The short answer is wire color to color. black to black, white to white, green or bare to green of bare.
