1 correct selection According to the total capacity of electrical appliances and specific use of the environment, select the appropriate switches and sockets. Humidity of the place, should use fire switch and pull switch; a corrosive substance or dust large room, can not install the switches, sockets, and should be installed on the outside; with combustion of explosion, fire or should be used Explosion-proof switch And sockets.
2 correct choice of rated current and rated voltage
Switch, socket rated current and rated voltage, shall be consistent with the electrical appliances in technical parameters. Can not be overloaded, so as not to burn insulation circuit overload caused by short circuit caused the fire.
3 fuse the right choice Knife switch Should be used to match the fuse. Does not allow any changes, especially bold melt, more does not allow use of copper, aluminum, iron and other metal wire instead of fuses.
4 pole switch should be installed in the phase line
Pole switch should control the phase line, not connected to the neutral line. Otherwise, even if the disconnect switch contacts with the human body if the same line and the neutral wire will cause electric shock. If the phase line to ground, but also short-circuit or even fire.
5 high-power electrical appliances should be Power supply Individual wiring
Avoid the use of lamp socket
As high-power electrical appliances (microwave ovens, electric stove, electric stove, air conditioner, etc.) work current, thus, electrical power should be used for such special socket, rated current of not less than 10A, preferably from connecting wire into the household Distribution box The pick up. Use aluminum wire, its sectional area of not less than 2.5mm2; use copper wire, its sectional area of not less than 1.5mm2, and try not to make high-power electrical appliances simultaneously. Do not use lamp socket. Because high-power electric lamp socket in use, will cause a fire because of severe overload.
6 electrical damage repaired, as soon as possible for wire aging
Switch, wire socket aging and damaged, repair and replacement in time to avoid the use of fire make do.
7 cut off time Power supply
Out, sleep or sudden power failure, power cut off in time, especially for electric appliances, should pay more attention.
8 installation environment stress Switches, sockets should be installed in a dry, clean, clean place, avoid moisture corrosion insulation breakdown caused by short circuit caused the fire.
9 to minimize the use of multi-purpose outlet
In rural areas, many families used a variety of electrical appliances connected to the same multi-purpose outlet, but these appliances also often open simultaneously. This seems very convenient, but in fact many drawbacks. Because the multi-purpose socket and power cable are rated capacity, a variety of household appliances with more than one socket at the same time use, it must lead to too much current, resulting in voltage drop, thus affecting the electrical work. If the voltage drop is too large, but also damage to electrical appliances, while also making wire due to heat overload and burn lines also cause serious fires. Another jack too much distance, improperly designed for easy precision, this could lead to electric shock. Thus, frequent use and location of fixed appliances should be individually inserted fixed socket.
10 times to wipe clean the plug
Electrical plug should always be clean, otherwise the polarization will gradually plug fouling or produce oxides, sockets and plugs to increase the contact resistance, thereby affecting the life or burnt out socket outlet, or even create a fire. Click to see more exciting information
