How do I wire a Ceiling fan that has a black wire and a white wire and a blue wire and the junction box has only white and black?

Answer 1

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.

YOU MUST CHECK WITH THE LOCAL ELECTRICAL SAFETY OFFICER FOR YOUR LOCALITY BEFORE YOU DO THAT.

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

=== === Asking this type of question usually means you aren't ready to do this yourself.

If you get any detailed "how to do it" answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

Answer 3

On most ceiling fan installations a three wire feed is used. A "hot" wire and the neutral feeder are brought to a two gang switch box from the distribution panel. One switch will control the fan and the other switch will control the light if there is one. On this type of installation the "hot" wire is connected to the top of both switches. The incoming neutral and the white from the three wire cable connect together in the switch box. From the bottom of the switch that controls the fan connect the black wire. From the bottom of the switch that controls the light connect the red wire. From the switch box the three wire feeder connects to the fixture box. In the fixture box the black wire of the three wire connects to the fan's black wire. The red wire of the three wire connects to the fan's blue wire to control the light. The neutral connects to the fan's white wire. The green wire from the fan connects to the bare ground wire of the three wire cable. In your case you can connect the fixture's blue and black together and the fan and light will both come on together. <><><>

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 4

White = neutral. The white wire of the voltage in simply connects to the white wire of the fan.

The green wire of the fan is the equivalent of the "bare" wire of the voltage in. Tie them together or connect both to a metal junction box.

The black wire from the switch (voltage in) should be the "switched" leg of the circuit. If the fan has both a black and a red wire, they will control the light and the fan. If you have separate switches for those circuits, connect them separately; if both are controlled by the same wall switch, connect both the red and the black to the BLACK wire of the voltage in, then you will be able to control the fan operation by the separate fan pull chain switch.

Answer 5

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.

Answer 6

What you have in the box, if things are done as expected, is either the black wire or red wire is switched on the wall and the other is often on all the time. You can check this by seeing how your switch or switches are wired.

In the fan, either the blue or black wire goes to the fan and the other goes to the light. If memory serves I believe the blue wire goes to the light. Check any labels that are attached to the wires.

These 2 configurations allow you to switch the light at the wall while leaving the fan running. It can also allow you to switch both at the wall with separate switches. Some people put a dimmer switch on the light. DO NOT make the mistake of attaching a dimmer switch to the fan.

What you have is the very best configuration possible. Someone knew what they were doing when they wired that box.

Answer 7

The Black and white wires in the fan would probably be the "main" power connections and the blue would be for remote control of some other feature, such as an integral light fixture, but you would be better off finding the proper wiring diagram for that device.

I have never seen a "light box" with red, black, brown and grounding wires. You should either have a black and a white or a brown and a blue, not a brown and a black.

Answer 8

idk but i think it takes two people to change a ceiling fan HAHA!

Answer 9

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