What are Red Wires?
Does the color of wire matter?

Blue and yellow wires are sometimes used as hot wires and as travelers, green wires (and bare copper wires) are ground wires, and white and gray wires are neutral.
What happens if you switch black and red wires?
If you switched the wires, what would happen? Red is positive charge, black is negative charge. If you aren’t running if you aren’t connected correctly.
What are the white black and red wires?
The white wire is always neutral, and when the cable has only two conductors, as most 120-volt cables do, the hot wire is black. … The red wire is for the light switch. This configuration, sometimes called a half-hot or split-tab outlet, is becoming increasingly popular, so it’s good to know how to wire it.
Which wire is live red or black?
Answered by Dave, Electrical Safety Expert
The live Red becomes Brown. The Neutral Black becomes Blue. The Earth wires continue to be Green and yellow.
How do you connect black and red wires?
Connect the “live” black wire coming from your breaker to one side of the switch, and the black wire going to your fan to the other terminal (the “load”). For the red wire, take a second switch, one side connected to the “live” black wire, and the other side will be the red wire.
Is a black and red wire positive or negative?
One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. 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 does Blue wire mean?

How can you tell which wire is hot neutral or ground?
Neutral wires should be white. However, if you see a white wire with electrical tape on it, that may indicate that it’s being used as a hot wire. And ground wires are often plain copper, but the ground wire color can be green. It’s also possible to have some other colors may come into play depending on the system.
Which wire is positive when both are black?
If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive. Look in the owner manual to determine which wires are negative in a car.
Why are both black and white wires hot?
like the title says both wires (black and white get or turn hot). To answer your question, Yes, that is correct. The reason you are getting 120 volts when the fan/light is on is because the voltage is feeding trough the motor or the light bulb (or both).
What do I connect the red wire to?
Normally you’ll see a red wire in places you would expect a ceiling fan. But in places like a bathroom or a wall light, if you see a red wire, it’s a good bet that the red wire is the wire that’s connected to the light switch.
Is black wire positive and red negative?
One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. 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.
Which wire is hot if both are black?
Here’s a rundown of electrical wires: The black wire is the “hot” wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel.

Answered by Dave, Electrical Safety Expert
