The wire square specification circuit design is generally:


The entrance line is 4-6mm², the lighting is 1.5mm², the socket is 2.5mm², and the air-conditioning line is 4mm².


After 2000, the circuit design is generally: entrance line 6-10mm², lighting 2.5mm², socket 4mm², air conditioning 6mm² dedicated line.


The wires used in home improvement are generally single-strand copper core wires, and their cross-sectional area mainly has three specifications, namely 4.0mm², 2.5mm² and 1.5mm². In addition, there are 6.0mm² specifications, which are mainly used for home main lines, 4.0mm² specification single-strand copper core wires are used for circuit main lines and special wires for air conditioners, electric water heaters, etc., and 2.5mm² specification single-strand copper core wires are used for socket wires and For some branch lines, 1.5mm² single-strand copper core wire is used for lamps and switch wires, and the ground wire in the circuit generally also uses 1.5mm² single-strand copper core wire.
