What color is the live wire in electricity?
brown wire
Wiring Colour Codes The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance.
Why are black and red wires used in electrical wiring?
These are the most common colors used in electrical wiring. Other color combinations, such as striped wires, may be used for other applications. Remember, black and red wires are always hot, meaning they are source wires that carry power from the electric service panel to a destination, such as an outlet or a light.
How to wire an electrical outlet with red, white and white?
You can now screw the outlet to the box and proceed to the switch box. You’ll have two cables in the switch box – a live one with a black and white wire and the one going to the outlet, which has a red, black and white wire. They should both be of the same wire gauge: 12 AWG for 20-amp circuits and 14 AWG for 10- and 15-amp circuits.
Can a black wire be used as a hot wire?
White wires augmented with red or black tape or markings are used as hot; however, a black wire can never be used as a neutral or ground wire, or for any purpose other than to carry a live electrical load.
Where do the white wires go on a fan?
The white wires on the fan go to the bundle of white wires. The black wire goes to the bundle of black wires. If you only have black wires in your box, connect both the non-white wires from the fan to the black wires in the box.
What do black and red electrical wires mean?
A black wire is often used in a circuit as a switch leg, the connection that runs from the switch to the electrical load. Red electrical wire indicates the secondary live wires in a 220-volt circuit, used in some types of switch legs and in the interconnection between smoke detectors that are hard-wired into the power system.

What does it mean when there is red wire in light switch box?
When you see a red wire in a light switch box, it can mean two things. It could be there is (or once was) a three-way switch in play. Or it could be the red wire is the wire going to the fixture, and the black wires are the live wires. We’ll cover the easier scenario first.
Can you use any color wire as a live wire?
You can connect a red wire to another red wire or to a black wire. Yellow and blue electrical wires are also used to carry power but are not for wiring the outlets for common plug-in electrical devices. These colors are used for the live wire pulled through conduit.
