Why light fixture has red and white wire instead of white and black?
In the US and Canada, the white wire is universally the neutral.
The "hot" wire can be red or black, both are used. Maybe the manufacturer was able to get a good deal on red wire.
Yes. Connect Black to Black, White to White and bare ground wires together.
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.
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.
As the power to the light fixture should be, and hopefully is off, it does not matter which you hook up first.
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 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"… Read More
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… Read More
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… Read More
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… Read More
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.
if fixture has two bulbs then two blacks are hot wires. Two whites are neutral wires.
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.
Yes, that is the correct connection.
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.
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.
lights can be wired any way round, there is no positive or negative
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… Read More
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.
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… Read More
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… Read More
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… Read More
The advantage is that black eye will absorb the light instead of reflecting it. Black absorbs light and white reflects all off it
just like swapping them except the wire is not color on a swag kit the side with the ridges is the neutral or white the other is the hot or black
very easy just pull your self a line from the outlet to the location you want to have the pull light fixture installed ,then connect the black wire to the black wire in the outlet white to the white and the copper ground to the ground then on the other end of the wire at the light fixture location connect the black to the copper screw and the white to the silver screw .and that… Read More
Any house built before 1950 probably only has 2 wires. Black and white. You do not need a ground, that is only to ground the fixture. Hook black to black and white to white and don't worry about it.
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.
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)… Read More
How do you connect a White Black Green wired device to household White Black Red ground light outlet?
If there is a red wire in the fixture box it sounds like the fixture is three way switched. The travelers are coming from one of the two switches and the cable is going to the second switch. See related links below.
How do you install a ceiling light that is running off two swithches my new fixture has 1 white wire and 1 black wire. the ceiling box has white and red and black are capped together?
This question isn't clear.
First you need to determine what the wire "pairs" are used for. Typically a light circuit uses one of the pairs for power source and the other for the switch leg. Determine which pair is the switch leg (a multi-meter is useful for that) and which is the power. Connect the white of the switch leg to the black of the power leg, then connect the remaining black and white to the black and white… Read More
If the voltage source is at the fixture box, the wire will be a two wire that goes to the switch box. The colour coding should be, black wire going to the top of the switch as a "hot" feeder and the return from the switch to the light fixture will be the white wire. The white is not a neutral and should be identified as such. This is done by wrapping black tape around… Read More
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… Read More
The standard is: the white wire is "Neutral", and the black wire is "Load".
Because it uses electrons instead of light, and light is required for color to be present.
White to white, black to black, and ground to copper wire.
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… Read More
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.
Light fixtures without a ground wire might be illegal in your area - check first. If the fixture has no ground wire, it is probably an antique or has been imported illegally, depending on where you live. The three wires in a typical house circuit (North American, 15amp) are the neutral wire (white insulation), hot or live wire (black insulation) and the ground wire (no insulation). The two wires attached to the light fixture should… Read More
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… Read More
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
to wire a 3-way like this you first need to run 14/3 romex wire from the light box to each of the 2 switch locations. at each switch connect wires as follows: white wire to common screw(usually black or brass) connect red and black wire to silver colored screws, does not matter which way. in the light box you need to identify you incoming power, once you have identified that wire connect one of the… Read More
If you have three wires coming into the box, black, white and bare, put it with the bare one. If you only have 2 wires, black and white or can't tell, you can attach it to the metal box that may be grounded or simply tuck it back and don't worry about it. It is there to ground the fixture but if you do not have a ground wire, the bare one, there is nothing… Read More
A typical motion detector has three wire on it. Black, White and Red. To install this on an outside light it get wired as follows. The White wire is the Neutral. It gets attached to the White feed wire and the white wire that hoed to the light. The Black wire feed power to the motion detector. It attached to the Black feed wire coming from the house. The Red wire on the motion detector… Read More
Most likely the 6 lights are fed from one another. At each light there will be a black, white and ground coming into the fixture and another set leaving. The light is connected to these wires by wire-nuts. Remove the light in question from the black supply wire. From your new switch run a typical Romex wire to the light. Put black electric tape on the white wire at each end to indicate it is… Read More
You switched the power and switch wires. There should be two sets of wires in the ceiling box. 2 black, 2 white, 2 bare. Two groups of three. The white wire going to the light is the incoming wire. The black one in that group is the power coming in. Take that black wire and connect it to the other black wire. The second black wire goes to the switch. The power comes back to… Read More
Black light is asborbed and white light is reflected
Black surfaces absorb all light. White surfaces do not "reflect black" as there's no such thing as black light.
If you have two wires in the ceiling, they should be black and white. Old wire it may be hard to tell. For two wires for just a light, it doesn't matter. You should wire black to black and white to white but nothing will happen if you reverse them. The light fixture should have black and white also and probably a green or bare wire for the ground. You could have 4 or 6… Read More
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… Read More
