What does wire color separation represent? What are the three colors of wires?

The blue line represents the neutral line, the yellow, green, and red wires usually represent the U, V, and W phases of the three-phase wire, and the yellow-green two-color wire represents the protective grounding wire.

Also, white is rarely used, and black is all in the connection lines in the electrical equipment box and cabinet. The national standard is red, yellow, and green are the fire line, and blue is the zero line; The ground wire is a yellow-green two-color line. There are three colors of the live wire, sometimes the color of the fire wire is different for different floors, usually what color of the line was originally developed by the developer in the room, and what color of the fire wire corresponds to when the circuit is remodeled.

Generally speaking, only the busbar is required to follow the color regulations; Phase A is yellow, phase B is green, phase C is red, the neutral line (i.e. the zero line) is light blue, and the protective neutral line (ground line) is yellow and green. In the automotive electrical circuit, the wires for different purposes are distinguished by different colors to facilitate the installation and maintenance of the automobile circuit.

Headlamps. Exterior lighting systems such as fog lamps: blue. Various auxiliary motors and electrical control systems: gray. Radios, electronic clocks, cigarette lighters.

Auxiliary device system: purple.

The color separation of household wires is mainly divided into zero line blue, live wire red, ground wire two-color wire, and some control wires such as: white wire, yellow wire, green wire and so on. The important point is that the colors of the neutral and ground wires should not be used indiscriminately.

So if there is a circuit diagram, Antu construction is the most standard! Weak wires are generally dedicated wires, so the color and shape are different.

In China, wires usually come in three colors, which are blue, brown, and yellow-green. They each represent the following meanings:1

Blue wire: Usually represents the neutral wire, also known as the neutral wire. It is a return line in a circuit that is used to return current from the load to the power source.

2.Brown wire: Usually represents the live wire, also known as the phase wire.

It is the main power line in the circuit and is used to carry current from the power source to the load. 3.Yellow-green wire:

It usually represents a ground wire, also known as a guard wire. It is a line used to protect personal safety, and is used to introduce the fault current in the circuit to the ground to prevent the occurrence of electric shock accidents. It is important to note that the color standards for wires may vary from country to country and region, so local electrical safety standards and regulations should be followed when conducting electrical installations.

Summary. In general, the three colors of wires are blue, brown, and yellow-green. They represent the following lines:

In general, the three colors of wires are blue, brown, and yellow-green. They represent the following lines:

Hello dear<>

In general, the three colors of wires are blue, brown, and yellow-green. They represent the following lines:

1.Blue line: This line is usually a neutral line, also known as a neutral line, which is used to reflow power into the grid.

2.Brown wire: This type of wire is usually called a nuclear fire wire, also known as a phase wire, which is used to send power into electrical equipment.

In general household circuits, black wires are usually used instead of brown wires. 3.Yellow-green line:

This kind of repentant punch wire is usually a ground wire, and its function is to protect personal safety, connect the potential between electrical equipment and the earth, and prevent accidental electric shock or other safety problems.

It should be noted that in some special occasions, different voltage levels, uses, and national standards may have different wire code standards. Therefore, when using wires, you should choose according to the specific situation, and during the installation process, you should carefully check the identification and instructions of the wires to ensure that the wires are correctly wired and achieve safe electrical results. In addition, when using electrical equipment, you should also pay attention to the correct operation methods and safety precautions to avoid danger<>

The three colors of wire usually refer to the color of the insulation layer of the wire, which are red, yellow, and blue, and are generally used in wire and cable systems in residential, commercial, and industrial locations.

Red wire: The red wire usually represents the live wire, which is the voltage wire in the wire, which is the forward transmission line of the current. Yellow wire:

The yellow wire usually represents the neutral wire, which is the zero-voltage wire in the wire, that is, the negative transmission line of the current, which is connected with the grounding wire to prevent the danger of leakage of electrical appliances. Blue wire: The blue wire usually represents the neutral wire, which is also the zero-voltage wire in the wire, but is usually used at the neutral point of the circuit.

In some cases, the blue wire can also represent a load line.

1. Red: It represents the line of fire, which is usually represented by the letter L. This color is very dazzling, visually can give people a sense of tension, and has a warning effect, so it is used in a live wire.

2. Blue and black: they represent the zero line, which is usually represented by the letter N, and belongs to the neutral wire in the wire. This kind of wire is generally disrespectful and electrified, and it will also be charged in special cases.

3. Green or yellow-green color: it represents a ground wire, which belongs to an insulated wire and plays a protective role in the circuit. Because after the neutral wire is disconnected, it will be electrified, and at this time, the ground wire can effectively avoid the electrified neutral wire from causing electric injury.

However, this kind of line script cannot be used as a phase line under any circumstances.

Wire.

The colors of the wires represent different uses and functions. Common wire colors are as follows:

1.Gray or white: Neutral wire, connected to the neutral point of the circuit.

2.Green or green and yellow: Ground wire, connected to the metal carrying enclosure of the device and to the ground.

3.Yellow or yellow-green: Grounding wire, which has the same function as a green or green-yellow or yellow-colored wire.

4.Blue: Neutral wire, connected to the zero point of the circuit.

5.Brown: The live wire, the argument line is connected to the positive pole of the circuit.

There are three types in total, namely the live wire, the neutral wire, and the ground wire.

The color of the fire line: The red line is generally used to represent the fire line of the Fan Shen Rock.

The color of the zero line: Generally, filial piety is represented by black or blue to represent the zero line.

The color of the ground wire: Yellow is generally used to represent the ground wire, and some also use green.

Generally speaking, the blue line in the wire represents the electrical route; The green and yellow lines represent the bare wires; Gray represents the neutral line.

Different wire colors represent different electricity. Black, white, green, red, blue, orange, brown and gray, the color of the insulating sheath on the outside of the wire often has its own referential meaning. Red is the fire line, blue is the zero line, yellow or yellow and white is the ground line, which is the most commonly used; Yellow, green, and red represent phase lines.

It can also be said that the live wire is electrified.

The blue color represents the neutral line, which is generally not electrified, but there are times when it is electrified. That is, when the zero wire is broken, this wire will be electrified.

The two-color represents the ground wire, this wire is the safest, and the function of this wire is to help the leakage trip after the zero wire is broken.

According to the regulations, the insulating protective sleeve used by the ground wire should be yellow and green in color, while the fire wire is mostly red and brown protective cover, and the zero wire is generally blue or green. When we usually check and repair the wires behind the socket, we must turn off the electric switch in the house in advance so that we will not be electrocuted.

How to distinguish wires by color.

The wires used in our homes can generally be divided into live wires, neutral wires, and ground wires, and these electric potato wires are usually wrapped with insulating protective sheaths of different colors, and we can distinguish what kind of wire it is according to the color of these protective sheaths.

According to the regulations, the protective sleeve used for the ground wire in the three types of live wire, neutral wire and ground wire should be yellow and green color, and the remaining live wire is mostly red and brown, and the neutral wire is mostly blue or green.

If we usually want to repair and check the wires behind the socket by ourselves, we must turn off the electric switch in the house in advance, so that we will not be hurt by the contact with the current when we touch the wires.
