Selection skills of sockets | universal extension socket

In order to further standardize indoor wiring, reduce potential safety hazards and waste of repeated disassembly and assembly, and work with enterprises to create a consumer environment where consumers are assured and the market is in a good order, the National Electrical Appliance and Intelligent Cooperation Alliance invited electrical experts to jointly launch "Electrical Appliances Safe to Home The series of recommendations provide consumers with detailed and effective knowledge in terms of material selection, wiring, switch socket design, telephone network TV circuit design, etc., and guide consumers to choose a home improvement company that suits them and how to communicate with designers during home improvement.
Although the switch socket is not a "big piece" like home appliances, it is related to the daily safety of the family, and it is the first line of defense to ensure the safety of the family's electrical safety, so you must not be sloppy when choosing a switch socket. Electrical experts specially reminded that different types of switches and sockets are matched in different places. For families with children, in order to prevent children from touching the socket holes with their fingers or metal objects, they should choose safety sockets with fuse shields.
Look at the brand
According to incomplete statistics, there are more than 1,500 domestic companies producing switch socket products, and the quality of the products varies greatly. Because many ordinary consumers do not have the method to identify the pros and cons of products, and they have limited knowledge of switch socket brands, It gives some unscrupulous businessmen a living space, and some fake and inferior products flow into the market. Of course, many large companies pay much attention to their brand image and have high requirements for product quality. After-sales service is relatively guaranteed. The quality assurance is usually no less than 12 years. Therefore, in order to use it with peace of mind, it is best to choose a large company or a brand with a good reputation for the switch socket.
Check appearance
The panel should have uniform color, smooth surface, no depressions, variegated colors, no bubbles, stains, cracks, swelling, lack of glue, deformation, scratches, shrinkage and other defects. Metal parts are free of burrs, cracks, corrosion marks, rust and screw head damage.
You should also weigh the weight when buying a switch socket. If the merchant chooses a thin copper sheet, it will feel lighter. However, the copper sheets and terminals used for good switch sockets are usually thicker and relatively heavy. Copper parts are a key part of switch sockets, and also a key part of identifying counterfeit and inferior products. Consumers should also pay attention when purchasing: some unscrupulous manufacturers will add iron plates to their products to increase the weight, we must see clearly when purchasing.
Identify the place
Different places should be equipped with different types of switches and sockets. There are often water and oily smoke in the kitchen and bathroom. It is best to install a splash-proof box or plastic baffle on the socket panel, which can effectively prevent short circuits caused by oil and water vapor intrusion. In families with children, in order to prevent the children from touching the socket holes with their fingers or poke the socket holes with metal objects, parents are best to choose a safety socket with a fuse.
In addition, when installing a three-hole socket, the ground wire must not be imaginary, let alone connect the ground wire directly to the gas pipe. These practices are quite dangerous. The ground wire is connected to the electrical shell. Once the electrical leakage occurs, it will cause electric shock.
Special socket
Household outdoor waterproof sockets, 220V 10A three-plug and two-plug plugs can be used in the non-protected state to meet household requirements. (Protection level IP66 can meet the needs of the family. IP66 is violent spraying in all directions without entering water, and soaking in 1 meter of water for 1 hour without entering water) It should be noted that outdoor sockets are generally made of plastic, and anti-aging should be considered.
Many people don’t know that there are already household 10A “fingerprint” outdoor waterproof and rainproof sockets. Use indoor splash-proof boxes instead of waterproof sockets. The splash-proof boxes can only be splash-proof, not directly exposed to water and rain, let alone anti-aging, so It is not safe, and the service life is not more than one year because of the UV life.
Outdoor sockets must have five proofings to be durable. Five preventions-----waterproof, dustproof, anti-chemical corrosion, anti-ultraviolet and anti-collision.
