Strengthen power management, avoid random wiring, random wiring, use mobile sockets carefully. Random wiring, random wiring, use of mobile sockets are actually adding electrical equipment on a certain line, increasing the current flow, which may cause overload. The mobile socket jack is obviously more than the fixed socket on the wall, if the mobile socket uses too much electrical equipment, the original line must be unbearable .

    In the process of line design, the capacity of the site should be accurately verified, the possibility of future new capacity should be fully considered, appropriate type of wire should be selected. Large capacity, should choose thicker wire. Circuit design and reasonable selection are the key steps to prevent overload. If the design and selection is improper, it will leave congenital hidden dangers that are difficult to rectify. Some small projects and places are not carefully designed and selected. It is very dangerous to choose and lay routes at will. New electrical appliances and electrical equipment should fully consider the bearing capacity of the original line. If the original line does not meet the requirements, it should be redesigned and reformed .

    The line should be constructed and laid by electrician qualified personnel in accordance with relevant specifications. The laying condition of the line directly affects the heat dissipation of the conductor. Generally speaking, the laying of the line should not pass through easy, combustible materials and stacking, which will lead to poor heat dissipation of the wire, heat accumulation, possibility of igniting combustible items around it, increasing the risk of fire in the case of overload; The line laid in the ceiling of the decoration of public entertainment places should be protected by steel pipes, so that the ceiling is separated from the line, and even if there are molten beads in the case of overload, short circuit, etc., it will not fall to avoid fire.
