Where do the black and white wires go on a light fixture?
In the US, the black wire is either hot or switched and is attached to the brass colored screw of the fixture. The white wire is neutral and goes to the silver plated screw of the fixture. The light fixture should be 120 volts. The black wire is the “hot” wire and the white wire is the “neutral”.
What happens if you mix up black and white wires?
It will produce a big spark and hopefully blow a fuse or trip a breaker. If you wire them together and then turn the power on, the spark will occur at the breaker or fuse.
How do you connect black and white wires?
You connect the black wires in the electrical box to the switch terminals, and the white wires to each other. The switch also has a green terminal for the ground wires, which usually are bare.
Does black and white wire matter?
It depends entirely on the situation. There are certain conventions and rules in different industries in different countries. In North America, the rule is that in single-phase household wiring (normal outlets) black is live and white is neutral.
Does the white wire carry power?
White or gray wires indicate neutral charged wires. However, neutral wires may carry power and pose a danger of electrocution if not handled properly. White and gray wires carry power back to the service panel. Both hot and neutral wires have the potential to shock and injure you if not handled properly.Jun 4, 2019
Is the black and white wire positive or negative?
Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground. You may see a copper wire instead of a green wire for the ground.
Is black positive or negative?
The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.

What is the difference between the White and green wires?
- The white will always be neutral, the other colors are hot circuits. Green or bare wire is the dedicated ground wire. White is neutral (tied to the system ground at the electric panel only) and Black is the hot. To remember the difference, think of black as death.
What do the colors of the wires mean in electrical wiring?
- In conduits, they may pull different color wires to keep track of different circuits. The white will always be neutral, the other colors are hot circuits. Green or bare wire is the dedicated ground wire. White is neutral (tied to the system ground at the electric panel only) and Black is the hot.
What is a black and white electrical cord used for?
- Such a cord would be suitable for DC circuits where one conductor would be positive and the other negative; and for AC circuits where the one covered with black (or other colored insulation) is “hot” or “line” voltage and the remaining conductor (likely white or gray insulation) connects to the neutral or ground ED side of the supply.
