How do you wire up a light fixture?

To attach to screw connections, bend the wire into a U-shape, wrap around the screw, then crimp the wire closed and tighten the screw. (White wire to silver screw, black wire to gold screw, ground to green screw.) To attach wires to wires, twist like-colored wires together and then twist a wire nut over them.

How do you hook up a 2 wire light fixture?

Connect the lead wires from the fixture to the black hot wire in the electrical box by twisting a wire connector to the ends of the lead and hot wires. Repeat these connections with the two white neutral wires from the light fixture and the white neutral wire in the light fixture box.

Does it matter which wire goes where on a light fixture?

Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.

What are the 4 wires in a light fixture?

Depending on the voltage needed on the two-wire line, the wiring between the two wires will be different. A four-wire electrical line has a red hot wire, a black hot wire, a white common wire and a ground wire. A two-wire line is usually a black hot wire and a white common wire.

Does a light fixture need to be grounded?

Yes, if you have a metal light fixture your fixture needs to be grounded. The ground wire exits your junction box, but it is not attached to your junction box.

What happens if you wire live and neutral wrong?

If your outlets polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.

What happens if you wire plug wrong?

But heres the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
