nowadays, the electrical system in housing construction is becoming more and more complex, the use of wire and cable and usage rate increasing, wires, cables and pipelines in buildings, arranged in a crisscross pattern dotted, brings great convenience to our life. however, on the other hand, a large number of wire and cable, a number of unsafe factors and people's awareness of the safety of electricity is weak, but also makes the incidence of wire and cable fire accidents are getting higher and higher.

2, do not stand on the wet ground to move or touch live objects or wire insulation damage, to prevent electric shock.
by 3, the total gate fuse should be reasonable, do not allow the use of copper wire, aluminum wire or wire to replace.
