The correct answer to your question will depend on the exact location of the light fixture, its voltage and its power rating. <><><> Whatever is going on, your present wiring situation is not just confusing, it is dangerous. The bare wires are not meant to carry current. They are not coated, and thus have no insulation to protect surrounding material from the heat created by electrical current passing through the wire. You need to cut the whole circuit off at the breaker box until you can get the situation sorted out. Otherwise, you could have an electrical fire. This is what is wrong. At some point in your circuit, some numbskull (probably not a professional electrician) connected something wrong. The thing about electrical circuits is, the current doesn't know what color wire it is travelling through. It travels just as easily across black, white, red, and bare wires. In fact, there is no real difference between any of the wires, except that the "ground" wire has no coating. Electricians use the coating colors so they can keep track of which is which. So it's really more appropriate to talk about hot, neutral, and ground wires than black, white, and bare wires. All the wires could have the same color coating, and the circuit would still work fine. The problem is, if you were trying to hook something up, you wouldn't know which wire was hot. So someone got smart and color coded the wires. By standard, electricians use the black wires for hot and the white wires for neutral, but only because they assume that everyone else does. If the previous "electrician" didn't, it screws everything up. And that's what happened here. Someone did something that was not according to standards. I would start with the switch box that controls this light fixture. There should be two bundles of wires coming into this box. Each bundle will have a black wire, a white wire, and a bare wire. The two white wires should be connected to each other, but not to the switch itself. The two black wires should be connected to the switch. The switch will have two brass screws on one side. The black wires should be bent into a hook and hooked around those two screws and the two screws tightened. It doesn't matter which is on top and which is on bottom. The two bare wires should be connected to each other, and IF the switch has a green screw at the very bottom, the two connected bare wires should be connected to that green screw. That's how everything SHOULD look. But, it may not be that way, which would explain why your light doesn't hook up correctly. You may have a black wire and white wired connected to the two brass screws, instead of two black wires. You may have a bare wire connected to one of the brass screws. You may have a white wire and a bare wire connected to each other. All of these are no-nos. Anything other than what I described above is unacceptable. Hot and Neutral are reversed. You should not be getting any voltage through the ground wire ... EVER !!
On many light fixtures the black and white colors do not matter, except as a safety standard; it should work either way. Typically, however, the black goes to the tip of the bulb and white (neutral) to the shell, for safety when the bulb is being replaced and the current may be on. If the light fixture has a switch, it should always switch the black (hot) connection.
In your case, the white to ground means that the "neutral" may have been accidentally reversed somewhere with the black (which should never happen), leaving the safety grounding wire as the only connection that will "work." It also could mean that the voltage is still "on" when the switch is off, and a person could be electrocuted by "completing" the circuit even with the switch "off". <><><>
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. 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.

∙ 14y agoThe black wire is the hot wire that carries the electricity, while the white wire is the neutral wire. The ground wire is typically green or bare copper. The black wire goes to the brass screw, the white wire goes to the silver screw, and the ground wire goes to the green screw on the light fixture. Make sure to turn off the power before wiring to avoid electric shock.
Connect the black wire from the light fixture to the black house wire, the white wire from the light fixture to the white house wire, and the green wire from the light fixture to the junction box ground wire or directly to the house's grounding system. Make sure to turn off the power before starting any work and follow all safety guidelines.
No, when connecting a pull chain switch, typically the black wire is connected to one terminal of the switch, and the white wire is connected to the other terminal. It's important to follow the wiring instructions provided with the switch to ensure proper installation.
The copper wire is the ground wire and should be connected to the ground screw on the light fixture mounting bracket or to the ground wire in the ceiling box if present. Make sure to turn off the power at the breaker before working on the wiring.
To string 2 light fixtures together, you will need to connect the wires of the first fixture to the wires of the second fixture using wire nuts. Make sure to connect the corresponding wires (e.g., black to black, white to white, and ground to ground). If the fixtures have separate power sources, you may need to run a new wire from the power source to the second fixture. It is always best to consult a licensed electrician if you are unsure about wiring electrical fixtures.
Connect one black wire to the live wire and the other black wire to the neutral wire. Make sure to follow the wiring diagram provided by the ballast manufacturer for accuracy and safety. It's recommended to consult a professional electrician for assistance if needed.

Yes. Connect Black to Black, White to White and bare ground wires together.
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.
That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.

ground is the black...

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.
Yes
To wire a two-wire fixture to a three-wire outlet, connect the fixture's black wire to the outlet's black (hot) wire, the fixture's white wire to the outlet's white (neutral) wire, and the fixture's ground wire to the outlet's ground wire or grounding screw. If the outlet has an additional red wire, cap it off with a wire nut as it may not be needed for this connection. Always turn off power before working on electrical wiring.
