Note that the blue wire is connected to the black fan wire so that they can both be operated by the same switch. Connect the ceiling fan blue wire to both the black fan wire and the black wire from the ceiling. This connection allows both the ceiling fan and light kit to be powered by a single light switch.

Also, Does blue wire go to white or black?
Black wire is for the fan. Blue wire is for the light, if light is included with the fan. White wire is neutral.
Moreover, Does black wire go to red or blue?
The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
What wires go together?
There is a white wire that is the “neutral,” and, finally, a bare copper wire that is the ground wire. When electrical wires are joined together the black wires must be hooked together, the white wires must be hooked to the white wires, and the ground wires must be hooked together.
Which color wires go together?
US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors.
How can you tell if a wire is positive or negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
What is the black wire in electrical?
Black wires are “hot” wires, which means they carry a live current from your electrical panel to the destination. They feed electricity to electrical outlets, switches and appliances from the home’s main power supply.
What does brown and blue wire mean?
Brown is your hot wire so you want to connect that to your building’s black wire. The blue is negative or return, so that will go to white.
Where does the blue wire go on a light switch?
The faceplate of a single, one-way switch has two terminals: “L1” is the terminal to which the neutral core wire is attached – the blue wire (traditionally black, before the change). “COM” or “Common” is the terminal to which the live core wire is attached – this is the brown wire (formerly red).
Does red wire go to white or black?
Sheathed cable with a red wire always is accompanied by a black wire, a white wire and a bare wire. Very old homes may have cable that excludes the bare 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.
Is the black wire positive or negative?
The coloring is as follows: Positive – 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.
What happens if you wire a light backwards?
Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
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. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
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.
What is orange electrical wire used for?
Red or orange wires are often used to provide the secondary phase voltage in a 220-volt application. Always assume that a red or orange wire (in addition to the black wire, which provides the primary phase voltage) is live.
What happens if you connect a positive wire to a negative wire?
If you connect positive to negative directly with a wire, you get a very low resistance circuit. The lower the resistance, the higher the current. The is called a short circuit.
How do you tell which wire is hot if both are black?
Place the prong of the multimeter’s black wire on the bare metal on the end of a white wire, then read the meter. If you get a reading, the black wire is hot; if you don’t, the black wire isn’t hot.
Which side of plug is black wire?
Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green.
Does the black wire go to L1 or L2?
Brown for L1, Black for L2 and Grey for common.
Do I connect the red wire to the black wire?
Red electrical wires are the secondary live wires in 220-volt circuits and are commonly found in a sheathed, multi-conductor cable. … You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.
Why do I have a black white and red wire?
Black, red, white with black or red tape will always indicate a hot wire. The term “hot” means these wires carry a live current from your electric panel to the destination.
Can I connect a white wire to a black wire?
A single black and white connected together is normal. It is part of a switch loop. A black connected to a group of whites is not normal and probably should be connected to the other blacks. It is normal to have a white connected to a group of blacks if a switch loop is used.
