Power outlets are used in many places in our family life. For example, it is necessary to use power outlets in damp places such as kitchens and bathrooms. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt rapid commutation device and smart braking device. A socket into which one or more circuit wires can be inserted, through which various wires can be inserted to facilitate connection with other circuits. The power socket has waterproof function, which can ensure our power safety to a great extent, and is also a method to prolong the service life of the socket. The following small series can learn about the selection and installation of household power outlets.The power socket is usually made of waterproof box, and a cover is embedded in the socket on the wall. And the contact parts of the box body are provided with waterproof pads, thus having waterproof function. However, this kind of power socket is called splash-proof socket, which cannot prevent direct water hammer. Professional power socket can be selected, reaching ip67 level, and can be used normally after soaking in water. However, some power outlets are plastic rainproof sheaths, which can only prevent rain. For the toilet power socket, the toilet is the wettest place in the home, and the socket is easy to splash water, so we should be extra careful when choosing the toilet power socket:When installing the power socket in the toilet, try to install the high-point water supply device;2. The power socket installed in the bathroom must be protected by a protective cover, and a switch with a plastic protective film should be selected;When purchasing the socket clamp, carefully check whether it is fastened, whether it has enough strength to insert the plug, and make the socket clamp have good toughness. At present, the structure of most socket fixtures adopts strong extrusion, which greatly improves the bite force between the plug and the fixture and avoids the heating caused by long-term use. At the same time, strong extrusion can also prevent the plug from falling, effectively reducing the occurrence of power failure accidents caused by considering factors;4, in the process of using the power socket, to ensure that the hand is dry, never wet hands to use the switch and socket;5. Be sure to choose a good quality power socket. The product itself is unqualified. How to use it safely may lead to electric leakage.Selection and installation of household power outlets. For home lighting, many people have also installed outdoor sockets. For example, in patio pavilions and balcony lighting areas, outdoor lighting is affected by rain, so the following points should be paid attention to when using sockets:1. try to install the socket in a place where the rain cannot be directly wet;2. Choose sockets with stable quality of big brands, such as power sockets, which are very good. If the quality of sockets is not up to standard, there is a great potential safety hazard when used in outdoor wet environment.3。 Try to cut off the outdoor power supply during thunderstorms to avoid any accidents and stay away from electrified areas.Outdoor socket should consider its anti-aging, waterproof and dustproof performance, so professional power socket must be selected.5. The waterproof level of sockets used outdoors is high, so it is recommended to use waterproof level above ip55.
