(Summary description)In order to prevent the connection from being pulled out of the plug or socket by accidental pulling, the national standard stipulates that the connection point of the rewirable plug and the socket must be a screw terminal, and there must be a flexible cord fixing part to strengthen the tensile force, only to be integrated Only non-rewirable plugs or sockets are allowed to be soldered. Users who assemble sockets by themselves, some use twisted wires or knots to connect plugs or sockets in order to save trouble. This is not standard and unsafe. Wire: my country's national standard clearly stipulates that the number of wires of the flexible cable should be equal to the number of poles of the socket. However, some of the three-plug sockets currently on the market have only two-core wires connected to the power cords and no grounding wires, so they cannot protect electrical appliances from grounding. The length of the cable: The length of the cable should not be too long. Try to use the power source as close as possible; secondly, the exposed part of the cable is also dangerous in the channel where people come and go. Once the line is aging or damaged by external force, it is easy to cause accidents of electric shock and injury. Therefore, it is best to install protective wire troughs in places that are easy to be touched by people. It is also dangerous to reel an overly long cord. Such long-term use will cause the cord to accumulate heat and easily cause a fire accident. Of course, this also has a certain relationship with the wire diameter. The thinner the wire diameter, the lower the relative carrying capacity. Like the small white sockets that almost every family had in the past few years, many of them have only two thin wires. For many electrical appliances and high-power applications that require ground wire protection today Electric appliances are overwhelmed and extremely unsafe. Reserved cassette: Please communicate with the oiler and bricklayer at home in advance. It is said that after the circuit modification is completed, the location of the abandoned cassette will be marked by the electrician, and you should pay special attention to the useful cassette. Sometimes you encounter more confused oilers and tile workers to block some useful cassettes.
