How do you wire light fixture with three wires when there are two house wires?

CAN'T. Must have 3-wire w/ground.
[First off, I want to admit that the wording of this answer is skewed. However, if you read the answer you will understand why. It is techinically correct in terms of the NEC. -TJNII]
The idiot that wired my house did this. To add insult to injury he connected the hot to one circuit and the neutral to another. I was almost electrocuted because of it.
Do it right or don't do it at all. Your negligence may kill someone.

∙ 13y agoLight 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 also be color-coded white and black, and there should also be an uninsulated copper wire usually attached to a green screw, which is the ground wire.
Make sure the power source is disconnected by either removing the fuse at the main panel, or by shutting off the breaker to that circuit. Test the circuit to make sure it is not live.
Attach the white wire to the white wire, the black to the black and the ground to the ground, and then make sure the two ground wires together are attached to the ground screw in the junction box (j-box) that holds the light fixture to the ceiling or wall. If there is no ground wire on the fixture, still attach the ground wire from the house wiring to the j-box.
If the light fixture wires are not color-coded, the white wire (from the house wiring) attaches to the wire that attaches to the shell (threaded part) of the socket, and the black wire attaches to the fixture wire that goes to the center tap of the socket. This way, when you unscrew the light bulb you will not get a shock by touching the threads of the bulb, because the neutral (white) wire is attached to it, not the live wire (black).

∙ 10y agoIf the light fixture's third wire is a green one then it should be tied into the ground wire in the box. The bare ground wire in the box is at the back and should be looped around a green terminal screw. Tie the fixture's green ground wire to this point. Then it is just white to white and black to black.d

How do you release dome from light fixture in ceiling fan?
Disconnect the fixture wires and remove the central mounting nut to release the dome from the light fixture in a ceiling fan.
How do you wire a 220 volts light?
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
Where does a new fixture's ground wire go when wiring in the ceiling of a 1940s-era house has only two wires and a metal clamp screwed into the wooden joists to bear the weight of the light fixture?
Just tuck it away in the box. Unless you run ground wires throughout the house it won't serve any purpose.
You are changing a light fixture but the wires are all the same color which one is the hot wire?
A light fixture will function normally either way. The hot and neutral wires are interchangeable. DANGER! This is only true of lighting fixtures!
What if the new light fixture has 2 black wires and no white wire?
lights can be wired any way round, there is no positive or negative
What if the light fixture has two copper house wires?
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.

How do you wire a fixture that had two hot and two neutral wires?
To install a new fixture to replace the one that was removed reconnect the two hot wires together and then reconnect the two neutral wires together. Place the two wires from the new fixture to the corresponding wire colours that you just spliced together. This wiring should be down stream from the light switch. When the switch is turned on the new fixture should light. If this is not the scenario of your question then more information needs to be given.
How do you replace dining room light fixture?
If you don't know how to install light fixture, I don't recommend that you do it by yourself. The installation theory is actually very simple - all you need to do is attach fixture on the ceiling (or any other place) and then connect the electrical wires (usually there are two of them). After that it's good to put the light cover over the fixture to improve the appearance.
