What do different colors of home decoration lines represent?
The distinction of household wire colors is not just for beauty, but also for safety and easy maintenance. Because different colors of home decoration wires represent different lines, correctly identifying and using these colors can avoid wrong operations as much as possible and reduce safety risks.
Household wires are generally divided into six colors: red, yellow, blue, green, black, and yellow-green. Among them, red, yellow, and green are usually used as live wires; blue is the neutral wire; yellow-green is the ground wire.
The live wire plays an important role in transmitting power in a three-phase circuit. In order to facilitate power transmission and conversion, a three-phase four-wire system is generally adopted. The wire drawn from the three phases is the live wire, that is, the phase wire. The neutral wire is the neutral wire formed by connecting the three tails of the three-phase electricity together. When the three phases are balanced, there is no current passing through the neutral wire, and the voltage difference with the earth is close to zero. The role of the ground wire is to prevent electric shock. It mainly connects the metal casing of household equipment or household appliances to the earth to play a protective role.
When decorating your home, it is recommended to choose one of the colors of yellow, green, and red for the live wire. Note that red must be the live wire. The neutral wire is blue, and the ground wire is yellow-green as required. By installing the wires according to the specified colors, we can clearly see the live wire, neutral wire, and ground wire, reducing the possibility of wrong connection in the line and facilitating future maintenance. At the same time, it can also avoid misoperation caused by not being able to distinguish the wires, which plays a good role in protecting people.
In China, relevant standards stipulate that different cables should be distinguished by different colors for construction, in order to correctly distinguish the live wire, neutral wire, and ground wire in the wire to prevent wrong operation. In general, construction units will color-code cables according to requirements. The use of wire color differentiation can effectively avoid safety hazards caused by chaotic use and maintenance of wires. If the yellow wire is used as the live wire and the neutral wire for convenience and material saving during circuit modification, it will be difficult for electricians to find the live wire and the neutral wire during future maintenance, which will bring inconvenience to maintenance and easily cause construction safety accidents.
Color-coding household wires can be installed according to the specified colors, so that the live wire, neutral wire, and ground wire can be clearly seen. Countries have formulated standards requiring different cables to use different colors, mainly to correctly distinguish the phase wire, neutral wire, and protective ground wire in the wire to prevent wrong operations. For example, home decoration wires are generally divided into six colors, red, yellow, and green are usually used as live wires, blue is the neutral wire, and yellow and green are the ground wires. According to this color-coding installation, the possibility of wrong connection in the line can be greatly reduced. This also makes it very convenient for us to find line faults. If the colors of wires are used randomly, there will be hidden dangers in the future use and maintenance process. For example, in order to save materials and save time when remodeling the circuit, yellow wires are used as live wires and neutral wires. During future maintenance, it is difficult for electricians to find the live wires and neutral wires, which brings inconvenience to maintenance and easily causes construction accidents. The color-separated wires allow maintenance personnel to quickly and accurately determine which is the live wire, neutral wire, and ground wire, avoiding misoperation due to not knowing the circuit.
If the installed wires are not color-coded uniformly, it is recommended to make additional marks on the wires and clearly mark them on the circuit diagram for future reference. In order to improve the safety of the circuits in your home, you can use low-smoke, halogen-free, flame-retardant cables as home wiring. Using high-purity oxygen-free copper as the wire core prevents overloads, and using self-developed environmentally friendly materials as insulation greatly reduces the risk of leakage short circuits. Only cables that meet the specifications can truly protect our lives and provide multiple protections for you and your family.
