The common wire specifications currently on the market are divided into 1.5 square millimeters, 2.5 square millimeters, 4 square millimeters, 6 square millimeters, 10 square millimeters, etc. according to the cross-sectional area of ??the conductor. Generally, the larger the specification, the The higher the current and voltage it can withstand, the more reasonable it can be according to the intended use when purchasing. .

Lighting fixtures and other places with low power consumption are suitable for 1.5 square millimeter wires;

There are circuit branch lines in switch sockets, so 2.5 square millimeter wires are suitable;

< p>High-power appliances such as air conditioners and refrigerators. The power of the main line of the circuit is relatively large, so it is recommended to use wires of 4 square millimeters and above;

The main lines entering the home or the central air-conditioning dedicated lines have a huge carrying capacity and are generally too thin to bear. It is best to use 6 square millimeters. mm and above wires.
