The wires used in home decoration are generally single-stranded copper core wires, and their cross-sectional areas are mainly in three specifications, namely 4.0mm2, 2.5mm2, 1.5mm2, and 6.0mm2, which are mainly used for home trunk lines. It is rarely used or used in home improvement, and is generally not included in the scope of home improvement circuits and wires.
4.0mm2 single-stranded copper conductor is used for main circuit lines and special lines of air conditioners and electric water heaters, 2.5mm2 single-stranded copper conductor socket lines and some branch lines, 1.5mm2 single-stranded copper conductor is used for lamps and switch lines, and 1.5mm2 single-stranded copper conductor is generally used for grounding wires in circuits.
It is best to use BVV2*2.5 and BVV2* 1.5 models for household power cord. Because BVV is a national standard code, it is copper sheath line BVV2*2.5 and BVV2* 1.5, which respectively represent 2 cores 2.5 mm2 and 2 cores1.5mm2. Generally, BVV2*2.5 is used as the main line and trunk line, and BVV2* 1.5 is used as a single electrical branch line and switch line. BVV2*4 is used for one-way air-conditioning special line, and special grounding wire is provided.
From the aspects of fire prevention, maintenance and safety, it is better to use the "national standard" copper core wire with the Great Wall logo for home decoration. General trunking load area is: decoration 1.5 mm2, socket 2.5 mm2 and air conditioner 2.5mm2.. It is best to connect the negative wire (neutral wire/ground wire) at home with green and yellow double-color wires instead of switch wires.
