Where is the hot wire in my light fixture?
If your fixture is wired with lamp-style cord rather than white (neutral) and black (hot) wires, identify the neutral wire by looking for silver conductors, writing, squared corners, or ribs or indentations on the insulation. The unmarked wire is the hot wire.
How to identify hot wire and neutral wire in light switch?
I show steps on how to identify a hot/black wire and a neutral/white wire in a old light switch. Step 1: Turn the power off to the area that you are working on.

How to locate a disconnect in electrical wiring?

Where are the wires on a light fixture?
Very likely, one of the cord wires is connected to the metal casing of the fixture (the part with the threaded rod). This is the fault ground for the lower part of the lamp. One of the other wires is connected to both shells. The last wire is connected to both tips.
How to tell if your house wiring is ancient?
If you are in the U.S.A. and your house wiring is not ancient, the fault ground will be bare, green, or green+yellow. The house neutral will be white, and the switched hot is never white and usually black or red. This is very helpful. I’ve ordered a continuity tester and will be able to have answer in a few days. – Steve Barden Nov 14 ’16 at 4:35
How can you tell which wire is hot in a light fixture?
If you get a very high or infinite resistance, it means the two wires you’re touching are the hot and neutral and the third wire is the ground. If the resistance is zero, one of the wires you’re touching is the ground. Now for the second part of the test.

Where does the hot wire go on a runner light bulb?
A light bulb has relatively low opposition. 110v on a runner hot wire goes into a switch, then out to a light socket, then through the lamp, out the “neutral” side of the socket on the wire back to the neutral bus. Now we shut off the light switch, cut the neutral wire in two, connect our meter to the ends of the cut wire, turn the switch back on.
How to identify the neutral wire in a hanging light?
Identify the neutral wire in the fixture by looking at the wires. In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
