Home Electrical Wiring Installation Considerations
 

The choice of wires related to the future of electricity safety, wire quality will directly affect our future quality of life. If the product does not meet the standard will cause serious life crisis and property damage.

House electrical wire in general, BVV2 x 2.5 to do the main line, the main line, BVV2 x 1.5 do a single electrical branch line, switch line.

House electrical wire matters needing attention:

1.Copper quality: the real copper is red, and brass is yellow. Another copper is very soft, brass hard.

2.Product certification: Wire product certification is the "CCC" certification mark, trademark, model specifications, rated voltage, length, inspection, manufacturing date, the implementation of standards, factory name, site, telephone and other logo are clear, and consistent with the product.

3.Wire diameter

To BV 2.5mm2 electric wire, for example, the national standard BV 2.5mm2 wire diameter of the standard 1.78mm, but the allowable error of 2mm, so now the best national market standard 2.5mm2 electric wire diameter is 1.76mm, radius 0.88mm. Then the copper wire area = 3.14 × 0.88 × 0.88 = 2.43mm2, BV 2.5mm2 is the copper wire cross-sectional area is 2.5mm2.
