Home wires generally use a few square

Currently on the market according to the common specifications of the wire size of the conductor cross-sectional area, divided into 1.5 mm2, 2.5 mm2, 4 mm2, 6 mm2, 10 mm2 and so on, the larger the general specifications, the higher the voltage of the current that can withstand the purchase of the object of use can be reasonably selected in accordance with the use of the object.

Lighting fixtures and other small power consumption, suitable for 1.5 mm2 wire;

Switching sockets exist in the circuit branch, suitable for the selection of 2.5 mm2 wire;

Air conditioners, refrigerators and other high-power appliances. Circuit main line power is relatively large, it is recommended to choose 4 square millimeters and above the wire;

Into the home trunk line or central air-conditioning line of this type of load capacity is very large, generally too thin line can not withstand, it is best to choose 6 square millimeters and above the wire.
