How many wires are there in ceiling fan motor?

If the ceiling fan has a light fixture included in the fan, then there will be three. A white, black and blue. The blue is for the fan if the owner wants the fixture to be switched individually from the fan. Other wise there are only two wires to connect to the fan, a black and white.


How do you wire a ceiling light fixture to a receptacle that has two black wires and two white wires?

Black is Hot and White is Neutral and there should also be a bare ground wire. One black/white/bare cable is supply for receptacle and the other is connected in parallel and goes to another outlet. You need your ceiling fixture connected to one of the wires coming into the receptacle box, Black to Black, White to White and Bare to Bare. However, assume you want to be able to switch the ceiling light with a wall switch unless there is to be a pull chain on ceiling light. To connect switch run a new wired from the receptacle to a switch and run a wire from switch to ceiling fixture. At original outlet connect as described above. At switch connect White wires together with a wirenut, then do the same for the bare wires. Connect Black wire going to ceiling to one side or switch and Black wire coming from original receptacle to other side of switch.


Outside porch lamp has no box just two wires coming in black wires are tied and don't connect to fixture just the white wires what is going on here?

You would have to provide more info to be certain what your problem is. Typically a black and white wire would connect to the two wires on the light fixture. The fixture should also be controlled by a switch that "breaks" the black (Hot Wire) to turn off the fixture. If you have a volt meter you can see if there is 120Volts between the black and white wires with switch on. If there is a single white wire going to fixture (Neutral), where is the "black wires tied" to. Maybe one of the black wires has broken off the fixture.


How do you replace an old light fixture with two sets of black white and ground wires with a new fixture that only has one set of black white and ground wires?

Connect black to black and white to white from the switch. Your old fixture may have had wiring for multiple bulbs so they could be switched separately.


How do you connect the new fixture with one black and white cable if the old fixture has 3 bulbs with individual black white and ground wires?

Connect the white and black wires back on to where the other black and white wires connected. There should also be a green pigtail coming out of the fixture which will be the ground. If it has a chain, then the wire running through the chain will be the ground wire.

How do I wire a multiple bulb ceiling light fixture?

The lighting fixture should have all of the bulb's leads brought to a central point in the fixtures junction box. All of the black wires from the bulb's socket will be tied together. The same applies to the white wires from the socket.The white wires are tied into the lighting circuit's white neutral wire and the black wires are all connected to the "hot" supply wire. Once these connections are made, the fixture can be bolted to the ceiling junction box.


If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?

If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.

Do you connect both wires on a pull chain switch one to black one to white?

There should be two wires in the box, black and white and possibly a bare one depending on the age of the wiring in the house. The fixture has two screws on the base. One wire goes on each screw. If there are short wires on the fixture, black to black and white to white. If there is a bare ground wire in the house box, it attaches to the body of the fixture. If there is no ground screw on the fixture, do not worry about it.


What colors do you connect the black and white wires from a ceiling fan if the house wires are red black white and ground?

I assume you mean the red, black, white, and ground wires are in the ceiling box where the fan is going to be installed. If this is the case, the black wire and red wires are "switch legs" fed from two switches on a nearby wall. Usually the black wire is used for the ceiling fan motor, and the red one is used for the fan light. If this fan does not have one, you only need to use on wire, either red or black, and cap off the other wire. The white wire connects to the white wire on the ceiling fan, and the ground connects to the bare copper wire (if supplied) on the ceiling fan. <<>> Usually in the fixture itself the black wire is for the motor and the blue wire is for the light.
