In home wiring, L1 typically represents the first line or phase conductor, which is usually the black wire. L2 represents the second line or phase, often identified by the red wire in a standard 120/240V system. The white wire serves as the neutral conductor, while the green or bare wire is used for grounding.
The standard color code for home wiring is black for hot wires and white for neutral wires.
White is neutral in home wiring. Red is sometimes used in 3-way switches and dimmer applications, so it is likely red is hot in your application if it pertains to home wiring. The term positive would just apply to DC wiring since AC goes positive and negative. For example your car battery has Red as Positive and Black as Negative.
At that point, you should verify the home wiring; make certain that the black wire IS, in fact, the "hot" wire and that the white wire IS in fact the neutral. If the house is wired properly, connect the new fixture with "black to black and white to white." If you aren't certain that the house wiring was done properly, contact a local electrician to perform the work for you. Connecting a light fixture improperly can be dangerous to you and to anyone who subsequently changes a bulb or otherwise comes in contact with the fixture.
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
hot wires are black, white wires are ground
it is the home jersey for the teams
In most home wiring circuits, the black wire is used to power a light bulb. The other wire is white and is called the neutral conductor.
They are insulators which provide support for the wiring. This type of wiring is known as "knob and tubing"
Team colors are red, black, and white. The home uniforms are red and black with white accents. The away uniforms are white and black with red accents.
In home wiring, hot wires are typically colored black or red, while ground wires are usually green or bare copper. In computer wiring, ground wires are typically black, while hot wires are often colored according to industry standards, such as red or yellow.
In a standard electrical system, the red and black wires are typically used for the positive connection, while the blue and white wires are used for the negative connection. However, it's important to check the specific wiring diagram or instructions for the device or circuit you are working with, as color coding can vary.
