Wire red, yellow, green "three brothers" they respectively represent what
In our life, we will come into contact with home decoration wire, red, yellow, green, blue and other colors, then do you know the meaning of the color of the wire represents? It is suggested that the color of the wire must be understood clearly, so that it is safe to use.
Home decoration wire each color represents what line? Home decoration wires are generally divided into 6 colors: red, yellow, blue, green, black, yellow and green. Firewire (denoted by L) : red, yellow, green; Zero line (denoted by N) : blue; Ground (denoted by E) : yellow and green.
Home decoration, it is recommended that the firewire only choose a color of yellow, green, red, should pay attention to is: red must be firewire, zero line on the choice of blue, ground wire according to the requirements of the choice of yellow and green two-color.
If the home has 380V voltage into the household, then the fire line three colors to choose, then we can open the hole in accordance with the circuit to choose yellow green red, with these three colors to distinguish different circuits.
What are the advantages of wire color? National standards require different cables to use different colors (countries), mainly in order to correctly distinguish the phase line, neutral line, protective ground wire, to prevent wrong operation, generally electricians will be in accordance with the requirements of color separation.
If the color of the wire is used arbitrarily, there will be safety risks in the future use and maintenance process. For example, in order to achieve convenience and save materials during circuit transformation, yellow wire is used as live wire and neutral wire. In the future maintenance, electrician is not easy to find out live wire and neutral wire, which brings inconvenience to maintenance and easy to cause construction safety accidents.
Install the wire in accordance with the specified color, we can clearly see the live line, neutral line and ground line, reduce the possibility of wrong connection in the line, but also convenient for future maintenance, can also avoid the wrong operation caused by the unclear line, and play a good role in protecting the person.
Therefore, the line in the wire color separation is very important, home decoration must be on the wire color separation. If the installed lines do not have uniform color separation, it is recommended to mark the lines and clearly mark the circuit trend diagram for later review.
