It is not advisable to install ordinary sockets in humid places such as kitchens and bathrooms to prevent corrosion or leakage.
6. The sockets of high-power electrical appliances are directly wired from the household distribution box
For high-power electrical appliances (air conditioners, microwave ovens, induction cookers, washing machines, refrigerators, etc.) because of the large operating current, the extra current of the socket used is not less than 10A. The connecting wire is connected from the distribution box into the household, and the cross-sectional area of ​​the aluminum core wire is not less than 2.5 square millimeters; the cross-sectional area of ​​the copper core wire is not less than 1.5 square millimeters. For some frequently moving electrical appliances, you can choose multi-purpose sockets, but you need to be careful not to open multiple electrical appliances together. Ensure safe operation.
7. It is necessary to add leakage maintenance to the socket circuit
The electrical appliances connected to household sockets are basically mobile appliances (vacuum cleaners, floor or desktop fans, and various small appliances) or fixed appliances (refrigerators, microwave ovens, electric heating showers, washing machines, etc.) that can be reached at any time. When the wires of these electrical equipment are damaged (especially the wires of mobile electrical appliances) or the live shell of the electrical equipment can be touched by human hands, there is a danger of electric shock. Except for wall-mounted air conditioner power sockets, other power sockets should be equipped with leakage maintainers. Leakage maintainer is a maintenance appliance to prevent leakage or electric shock. When the leakage current of the electrical appliances and wires behind the leakage maintainer exceeds the extra value (the operating current of the household leakage maintainer is less than 30 mA and the operating time is less than 0.1 second), the device will trip and power off. It is often used in conjunction with maintenance grounding or maintenance grounding to form two layers of protection against electric shock.
8. Select copper core wire for the lead of the socket
9. There should be obvious differences between sockets of different voltages. Not interoperable
