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.

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.

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.

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.

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.

How do you wire a two wire fixture to a four wire outlet?

Wiring a 2 wire fixture to 4 wire outlet depends on configuration of wires in outlet box. If you have 2 white and 2 black I will assume there are more lights controlled by the same switch. 1st scenario attach both black wires to black of 120 volt fixture. Attach both white wires to white wire from fixture. atach ground to box or ground wire. 2nd scenario attach white neutral to white from fixture, Attach black hot to white going to switch. Attach black from switch to black from light Fixture. If you need further help I recommend hiring a contractor. Take a look into

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.

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.

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.

Is it ok to connect the white wire to the black wire in house wiring?

No it is not a standard practice. That said you will find such a connection from a light fixture junction box, that has the supply source in it, down to a a light switch junction box. The neutral for the light is already at the light junction box but the switched leg has to go down to the switch. The black "hot" wire is connected to the white wire in the cable going to the switch and from the switch it returns in the black wire in the same cable which is then connected to the light fixture.

Do you connect the white wire to the black wire?

In some cases in residential wiring you do. From a light fixture junction box to a switch box, the cable is a two wire, black and white. To connect the switch into the circuit at the fixture box, the "hot" conductor is connected to the white wire that goes down to the switch. The switched "hot" comes back on the black wire and this is then connected to the fixtures black wire. The white (neutral) is picked up in the fixtures junction box and connected to the fixtures white wire.

How do you hook up outside light fixture that has black white green to house wiring with only black and white?

If your house wiring is encased in armoured (metal) sheathing back to the panel, then you can secure the green ground to the ground screw in the box. Make sure the armoured cable connector is tight on the box. This should ground the light back to the panel. If you are on "knob & tube" I would suggest thinking about re-wiring the house.

How do you wire your new fixture if your old light fixture has a black wire connected to a red wire and a red wire connected to a white wire?

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.

What happens when you connect black and black wires together when white and white are already together and not being used?

This sounds like a typical light switch connection that turns on an overhead light fixture. There are two pairs of wires in from the supply voltage and two pairs of wires out to the light fixture. The two white wires are connected together in the back of the box. These are the neutrals from the supply to the light fixture. The two black wires are the ones that get attached to the switch. Incoming "hot" to the top terminal of the switch and the outgoing black to the bottom terminal of the switch. If you just touch the two wires together as you explain in your question then the light fixture should come on.

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.

Can you add additional wiring for another light through existing light recepticle?

Yes, as long as you don't increase the load in access of the circuit capacity. Just connect new wire in parallel - That is black to black, white to white and bare wire to bare wire. Make sure power is off before doing any wiring. Make sure connections are made properly and made inside the light fixture electric mounting box.

How do you wire a ceiling fan with black blue and white wires to a light box with red black and brown wires and a ground?

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.

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.

New light fixture has 2 black wires and 2 white wires?

if fixture has two bulbs then two blacks are hot wires. Two whites are neutral wires.

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 a two wire fixture to a three wire outlet?

In the outlet, as a general rule, The Black is the power The White is the neutral (Which is alot like ground) The copper is Ground. (In fixtures, ground is sometimes green) As a general rule, a fixture has a black power and a white neutral. There are Youtube videos that will teach you about house wiring.

What is the proper way to wire a four tube and two ballast floresent ceiling light?

There should be a black & white wire coming from the light. Hook black to black and white to white. Then connect the ground wire to the light chassis. You need 12/2 with ground for the circuit. You do not need a light fixture box for these type lights.

Why do i have two black wire in a light fixture and the white wires are wire nutted together?

It sounds like the light fixture's junction box is used as a through box for additional devices further along in the circuit. This would account for the two white wires being connected together to continue the neutral to another load device. As for the black wires, one could be the "hot" into the junction box from the distribution panel supply or a return "hot" from a switch that controls the light fixture. The other could be a feeder that connects the first fixture to a second fixture. Without seeing a photo of the wiring and what other wires are in the same cable set, it is hard to state completely what the wires do.

How do you wire 6 recessed fixtures in succession on a 3 way switch?

If you already know how to put one fixture on a 3-way, just connect white-to-white and black-to-black from one light to the next. If you're changing from a single switch to the 3-way, the exact wiring will depend on whether the power comes from the breaker box to the switch or the existing fixture. I'll assume you're starting from scratch or have the power going to the fixture. You need #15 two-wire with ground and #15 three-wire with ground romex. Run two-wire from the breaker box to the first light fixture. Pull a another two-wire from this box to switch A and a three-wire between the switches. String two-wire from the first light to the second, second to third, etc. In the first box, connect white from source to the white fixture wire and the white going to the second box; black from source to the black to switch A; and the black fixture wire to both the white to switch A and the black to the next fixture. At each of the other 5 fixtures, connect all white to white and black to black (three pair in each box except the last one). At switch A, connect the white from the fixture to the common (center) connector and the black directly to the black going to switch B. The red and white wires going to switch B are connected to the two outside connectors of switch A. At switch B, the black goes to the common connector and the red and white to the outside connectors. At each box, connect all the bare wires (second ground) to each other and to the fixture or box. Now turn the power back on. If all the connectors are tight, power should follow the black wires from source past the fixture and switch A to switch B. From there it will go through one or the other of the travellers and, if switch A is in the same position as B, up the white switch leg to the fixtures, turn on all the lights and go back to ground.

Where does the white wire go on a light fitting?

In home wiring the white wire is neutral. Some light fixtures that are typically out of reach may not differentiate between hot (black) and neutral (white). In this case the black and white supply wires can arbitrarily connected to the two fixture black wires, one to each. The NEC requires that the neutral be connected to the screw shell of a 'typical' light socket regardless of height. This allows that while changing out a lamp (called a bulb), if you inadvertently come into contact with the screw shell, you are not in danger.

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.
