How to choose colorful household cable
In the world of household wires, each color has a unique mission. They are like guards who silently protect the safety of household electricity use, each doing its own job. In standard electrical specifications, red, yellow, and green are often used as live wires, blue represents the neutral wire, and the yellow-green color is the exclusive mark of the ground wire. These color distinctions are not set casually, they are directly related to electrical safety. If the colors of the live wire and the neutral wire are confused, when repairing or replacing electrical equipment in the later stage, the electrician will be like groping in the dark, and it is very easy to make mistakes and cause electric shock. If the ground wire does not have a distinct yellow-green color mark, once the electrical appliance leaks electricity, the current cannot be directed to the ground in time, and the consequences are disastrous.
The live wire is commonly used in red, yellow, and green. It is like a "transporter" of electricity, continuously delivering 220V voltage from the power supply to various electrical equipment, providing power support for our lives. In the entire circuit system, the live wire plays an important role. But because it is charged, you need to be extra careful when operating it. If you accidentally touch the live wire, a strong current will instantly pass through the human body, causing an electric shock accident and endangering your life. Therefore, before performing any circuit-related operations, you must make sure that the power is cut off and never take it lightly. The neutral wire is generally marked in blue. The neutral wire undertakes the important task of transmitting the current of the electrical appliance back to the power supply after use, so that the entire circuit forms a complete closed loop. Although the neutral wire is not charged under normal circumstances, in some special circumstances, such as when the neutral wire is broken, it may be charged, and there are also safety hazards. Therefore, in daily use and maintenance of circuits, the neutral wire cannot be ignored.
The ground wire appears in a unique yellow-green color. When the ground wire connects the metal shell of the appliance to the earth, once the appliance has a leakage fault, the current will flow into the earth through the ground wire instead of through the human body, thus avoiding the risk of electric shock. In addition to the common live wire, neutral wire and ground wire colors mentioned above, wires in colors such as white also have special uses in home decoration. Although these special-purpose wire colors are not as widely used as live wire, neutral wire and ground wire, they also play a key role in specific circuit scenarios. Understanding their uses can make us more calm and confident when facing complex circuit problems.
The specification of the wire, like its "capacity level", directly determines the current and power load it can carry. Generally speaking, the power of the lighting circuit is relatively low, and 1.5 square millimeters of wire is usually enough to meet the demand. For ordinary sockets, 2.5 square millimeters of wire is a more suitable choice. It has a stronger current carrying capacity and can cope with the power demand of many common electrical appliances such as TVs, computers, and small fans, providing stable power support for these appliances. When it comes to high-power appliances such as air conditioners, electric water heaters, and induction cookers, 4 square millimeters or even thicker wires come in handy. If there are special high-power demand devices such as electric vehicle charging piles and home floor heating systems at home, 6 square millimeters of wire is the key to ensuring power supply. When choosing the wire specifications, be sure to make reasonable calculations and selections based on the actual power and usage of the home appliances. If the wire specifications are too small and cannot meet the power demand of the appliances, it will cause safety problems such as heating and short circuits; if the specifications are too large, it will not only cause cost waste, but may also cause inconvenience during the construction process.
In the home decoration wire market, there are many brands that are dazzling. Choosing a well-known brand of home decoration wire is like taking out an "insurance" for the safety of home electricity. Like Yuejiaxin Wire and Simsheng Cable, it is a well-known domestic brand with stable and reliable quality. The product uses high-purity copper core, excellent conductivity, low resistance, and can effectively reduce power loss; the outer skin is made of fire-resistant PVC material, which has strong high temperature resistance and can maintain good performance even in high temperature environment, greatly reducing the risk of fire caused by short circuit.
The selection of household wires is like laying the foundation for the safety and beauty of the home. From the aesthetic considerations of color matching to the rigorous identification of materials, specifications, and brands, every link is related to the safety and comfort of household electricity use. Home decoration wires of different colors not only light up the appearance of the home, but also silently guard the safety of electricity use. When decorating, don't let the home decoration wires become a forgotten corner. Spend more time and carefully select them to make your home both beautiful and safe.
