in general, our family uses wires with a wire diameter of 2.5 square meters, which can be said to be basically suitable for our family. Because the 2.5-square-meter safe current carrying capacity can be as low as 20 amps in the home, the 2.5-square-core copper wire can handle almost 4,500 watts. Think about it, our family can use electricity, it is generally difficult to reach 4,500 watts. Therefore, 2.5 square copper core wire is basically enough in the family.

However, in order to satisfy the possibility that we may increase the household appliances in the future, there is also a requirement for a certain amount of wealth, and it is necessary to appropriately increase the wire diameter of the wires of the home circuit. We can follow this principle to choose the wire diameter of household wires. The lighting circuit selects 2.5 square copper core wire, the ordinary socket circuit selects 2.5 square copper wire, the wall-mounted air conditioning circuit selects 2.5 square copper wire, the cabinet air conditioner circuit, it is recommended that you choose 4 square copper wire, kitchen circuit I suggest you choose 4 square copper wire, bathroom circuit, it is recommended that you choose 4 square copper wire.

The wire diameter of some of the above household wires recommended by the individual can basically meet the needs of most families, can be reference.
