What wire does the blue wire connect to?
The blue wire from the ceiling fan gets connected to the second live wire from the ceiling.
This second wire can vary in color but is most commonly red or black.
This connection allows you to power your lights from the second switch..
Can I connect red and black wires together?
Red Electrical Wires These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire.
Is the hot wire black or white?
Hot, Neutral & Ground Wires The third conductor is bare copper. The black wire is the hot wire. It provides a 120 VAC current source. The white wire is the neutral wire.
What color is hot wire in a 120 volt circuit?
Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/480 V. For grounding, regardless of the voltage, Green (or a bare wire) is used.
Which wire is hot if both are black?
The United States has strict codes relating to home wiring, including clearly defined colors on the outer casing of the wires. Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires.
What happens if you connect a hot wire to a neutral wire?
If the hot wire comes into contact with both the neutral and the ground, then it will flow through both wires back to the source but as the ground has less resistance more current will flow through it.
Is Red live or neutral?
Black (neutral) Red (live) Green and yellow (earth)
What is a black wire on electrical?
Black electrical wire is used for power in all circuits. … Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet. A black wire is often used in a circuit as a switch leg, the connection that runs from the switch to the electrical load.
Why would a white wire be hot?
This enables current to flow through the light bulb and power it. If the neutral is disconnected anywhere between the light bulb and the panel, then the neutral from the light to the point of the break in the neutral will become hot (and the device will be unpowered, because no current will be flowing through it).
What are the colors of electrical wires?
Yes, electrical wire colors do matterGreen, green with a yellow stripe, or bare copper. These are ground wires that keep you, your appliances, and your home safe from electrical fires. … Black. Black indicates a hot or live wire that’s carrying a current and is used for power in all circuits. … Red. … Blue & Yellow. … White or Gray.
What color is positive wire?
redPositive – The wire for the positive current is red. Negative – The wire for the negative current is black. Ground – The ground wire (if present) will be white or grey.
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).
Are red and black wires interchangeable?
Red and black wires are current-bearing, and their positions are interchangeable. The central white wire is neutral.
How do I know which wire is hot and neutral?
Flat cords that have only two wires, such as those used in most lamps, are not marked by colors. The hot wire is always smooth on the outside of the cord, while the neutral wire is ribbed on the outside. For flat cords with polarized plugs on the end, the larger prong (or terminal) is the neutral wire.
Can a white wire be hot?
The term “hot” is used for source wires that carry power from the electric service panel to a destination, such as a light or an outlet. Even though you are permitted to use a white wire as a hot wire by marking it with electrical tape, the opposite is not recommended or allowed.
What happens if you reverse hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. … This wire is commonly referred to as the neutral wire, and it should always be white.
Why does light switch have 2 black wires?
The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault. In most cases, two black wires will be attached to the switch’s two terminal screws.
Why do I have 2 black wires and 2 white wires?
If there is power in both the up and down position of your light switch, than that is the hot power. If the light was fed power first than here is how you connect the wires. Take your black (hot all the time wire) and marrett it onto the white of the opposite cable (that brings hot power down to your switch).
