How to choose the square of the wireChoosing the square number of wires requires consideration of multiple factors, including the power, current, length, etc. of the electrical appliance, and different appliances require different square numbers of wires. 1、 Power and current The power and current of electrical appliances are important factors in choosing the square number of wires. The greater the power, the greater the current that needs to be carried, and the larger the crosssectional area of the wire. Generally speaking, the square number of wires for household appliances and lighting appliances is between 1.52.5, while the square number of wires for highpower appliances needs to be between 46. 2、 Length The length of the wire also affects the selection of the square of the wire. Wires have a certain resistance when transmitting current, and the voltage consumed by the resistance will cause a decrease in voltage. If the distance between the wires is too far, the resistance will be very large, which can cause problems in the use of electrical appliances. Therefore, the length of the wire is also an important factor in choosing the square of the wire. The longer the length of the wire, the larger the square of the wire needs to be. 3、 The square number of wires required for different electrical appliances 1. Air conditioner: The power of the air conditioner is high, and the required square number of wires is generally 46. At the same time, attention should be paid to the influence of wire length. 2. Washing machine: The washing machine has a small power and generally requires 1.52.5 square meters of wires. 3. Refrigerator: The power of the refrigerator is also relatively small, and the required square number of wires is generally 1.52.5. 4. TV: The power of the TV is relatively small, and the required square number of wires is generally 1.52.5. In short, when choosing the square number of wires, multiple factors such as power, current, and length need to be considered. When purchasing wires, choose the appropriate square number of wires according to your needs, and pay attention to whether the length of the wires will affect their performance.
