What does the color of the power cord represent?

The red wire is the hot wire, the blue wire is the neutral wire, and the yellow or yellow and white wire is the ground wire. The 220-volt electric phase wire is a live wire, usually red or brown, the neutral wire is blue, green, or black, and the ground wire is yellow and green. Generally speaking, red will be used to represent the fire wire, and the letter l will be used to represent it. Red itself is a dazzling color. After seeing it, there will be a sense of tension, and it can also serve as a warning. Generally, red or brown wires are charged. There is also a blue or black line. Generally speaking, this line is the zero line that everyone often says, represented by the letter n, and belongs to the neutral line. In some cases, light blue is used to indicate the zero line, and the lines of these colors are generally uncharged, but the case of being charged cannot be ruled out. BV lines are generally divided into 8 colors: red, yellow, blue, green, double, black, white, brown. Usually: red, yellow, and green are used as live wires, red must be live wires, blue is neutral wires, two-color wires are used as ground wires, and black, white, and brown are used as replacement wires. If the wire color is used randomly, there will be safety hazards in the future use and maintenance process. For example, for the sake of convenience and material saving during circuit modification, yellow wires are used as live and neutral wires. During future maintenance, it will be difficult for electricians to find the live and neutral wires, which will bring inconvenience to maintenance and easily cause construction safety accidents. Install the wires according to the specified color, we can clearly see the live wire, neutral wire and ground wire, reduce the possibility of wrong connection in the line, and facilitate future maintenance. Generally speaking, different colors of the power cord have different meanings. We can judge what kind of wire it is according to the color.
