1, in line design process, should accurately approve the site capacity, fully consider the possibility of new capacity, select the appropriate type of wire. Large capacity, thicker wire should be selected. Line design, reasonable selection is the key step to prevent overload. If the design of improper selection, will leave difficult to rectify the congenital hidden danger. Some small projects, places do not carefully design selection. It is very dangerous to choose and lay the line randomly. New appliances, electrical equipment should be fully considered the original line to withstand capacity.

The original line does not meet the requirements, should be redesigned, modified. 2, the line should be in accordance with the relevant specifications, so that the electrician qualified personnel to lay the construction. The laying condition of the line directly affects the heat dissipation of the conductor. Generally speaking, line laying should not cross the easy, combustible material, stacking, this will lead to poor cooling of the conductor, heat accumulation, the possibility of igniting combustible goods around the ignition, increased the risk of fire caused by overload; public places of entertainment decorate the ceiling should wear steel pipe protection, so that the ceiling and line separated, in overload,

Short circuit and so on, even if there is no melting bead will not fall, to avoid fire. 3, strengthen power management, avoid disorderly wiring, disorderly lap line, use mobile socket carefully. Disorderly wiring, disorderly lap line, the use of mobile sockets is actually in a certain section of the line to add electrical equipment, increased the flow of electricity may cause overload. Mobile socket Jack significantly more than the wall of fixed sockets, if the mobile socket on the use of excessive electrical equipment, the original line must be unbearable.
