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.

Too vague an inquiry where do the old and new wires go and what do they do? Your question suggests that the existing house wiring is not visible as black or white. If so, read on. There should be a third wire which is either green but most often bare uninsulated copper in your old household wiring. If such a wire exists you need an electrical meter which displays a/c voltage. They are relatively inexpensive and quite handy. Following the instructions with your meter, touch the (-) meter probe to ground and the (+) probe to one of the old household wires. If you get no voltage reading, presume it white (neutral) and proceed to the other wire. If the other wire reads close to 115 volts you have the black (hot) wire. Label them with identifying tape to avoid any confusion and double-check to confirm your decisions. Caution: If you are dealing with household wiring not readily apparent to be black and white, to match your new fixture, it may be an old installation worthy of review by a licensed qualified electrician. Further, electricity is very dangerous and you should proceed with great care and knowledge. When dealing with electricity and electrical appliances, always consider consulting an electrician if you lack the competence.

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.

If it is a simple light fixture it does not meter - the light-bulb is a simple element of a chain that can be connected both ways.

You want to install a new light fixture in your bathroom upon removing the old fixture down you discover there is no grounding wire only a black and white wire and GFCI outlet on the circuit?

Just install the new fixture with black to black, white to white, and cap off the ground wire on the new fixture. It'll be fine.


When you connect earth wire in ceiling light does not work when connecting earth from light direct to earth wire coming from ceiling trips out when take earth wire out light works?

By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.


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.


Do you connect black wire to gold screw and white wire to silver screw in light fixture?

Yes, that is the correct connection.


How do you wire an exhaust fan to an end of circuit switch?

Answer for USA, Canada and countries running a 60 Hertz supply service.I want to add an exhaust fan to the existing light switch, it's already on a 20 amp circuit, it's only got 1 light and 2 receptacles on it. However, I popped the cover off the switch today to find that the switch is not wired normally, with the 2 white leads tied together behind the switch, and the black leads going through the switch. Instead I have only 1 black lead, and 1 white lead in the box. The white then leads back to the black lead on the existing light. With just the two wires in the switch box, it means that the junction you will have to tie into is in the light fixture junction box. The usual wiring in this type of connection is, the circuit "hot" is connected to the white wire that goes down to the switch box and connects to the top of the switch. Code states that this wire should be identified as a "hot" conductor by having a black tape identifier on it. The voltage returns back to the fixture on the black wire from the bottom terminal on the switch. To tie a fan into this circuit it has to be paralleled to the light fixture at the light fixture junction box. Connect the fan feeder's white wire to the neutral (white wire) in the light fixture junction box. Connect the fan feeder's black wire to the black wire that returns from the switch and parallel it to the wire that is now connected to the light fixture. This will give you a connection that will turn on the light fixture and the new fan, from the same switch.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Can you run power from a light fixture to another light fixture?

Yes. Connect Black to Black, White to White and bare ground wires together.

Do you hook up white or black first when changing a light fixture?

As the power to the light fixture should be, and hopefully is off, it does not matter which you hook up first.


Can you change an electrical outlet into a switch for a light?

Sure. For a light you need a fixture to hold the light and the light itself. The light needs to be connected to a voltage supply which you can get from the outlet. In the outlet box you will have a black, white and bare ground wire. Essentially you connect the white and bare wires directly to the light and switch the black wire (hot) through a switch.

How do you install a ceiling fan with red black and white wires?

Based on your description it is very likely that either the red wire or black wire is switched and the other is on all the time. In most cases the light of the fan, if it has a light, is connected to the switched wire and the fan is connected to the unswitched wire. This allows you to turn off the light while allowing the fan to remain running. There is no way to know without testing which wire is switched. The white wire is the neutral, connected to the white, or neutral, or common conductor of the fixture. There should also be a bare or green wire in the box to connect to the ground wire of the fixture.


When wiring a light fixture does black go black and white on white?

If these are all the wires you have then this would be a great assumption. It assumes also that everything before the fixture is wired correctly and with commonly used color schemes.


How do you wire two light fixtures?

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.


When connecting a ceiling fan in an old home and the existing light is wired black to white and white to black what should you do?

At that point, you should verify the home wiring; make certain that the black wire IS, in fact, the "hot" wire and that the white wire IS in fact the neutral. If the house is wired properly, connect the new fixture with "black to black and white to white." If you aren't certain that the house wiring was done properly, contact a local electrician to perform the work for you. Connecting a light fixture improperly can be dangerous to you and to anyone who subsequently changes a bulb or otherwise comes in contact with the fixture.

My light fixture has writing on one wire but not the other?

If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.


Do you connect black wire to gold screw and white wire to silver screw in light fixture?

Yes, that is the correct connection.
