1. Observe whether there is a clear mark on the product: such as model, rated voltage, rated current and related warnings, etc. The national standard clearly stipulates the rated current of plug and socket products. Civilian products are divided into 6A, 10A, and 16A, and there are three levels.
2. Plugs and sockets are products listed in the national compulsory certification catalogue. Please do not buy products without the "CCC" certification mark.
3. Try to go to regular markets and shopping malls to buy brand products of well-known companies, especially products that have passed the national supervision and random inspection many times.
4. Attention should be paid to whether the ratings of the product plug and the socket part match, that is, the rated current of the plug must not be less than the rated current of the socket. The order of the rated current should be plug ≥ power cord, mobile socket or converter multi-purpose electrical appliances, do not reverse it, otherwise it will cause safety accidents.
5. The plug should be in good contact when inserted into the socket, without feeling loose, but it can be pulled out without too much effort.
6. The copper sheets and terminals selected for a good industrial plug and socket are usually thicker and relatively heavy. Copper parts are the key part of industrial plugs and sockets, and they are also the key parts to identify counterfeit and inferior products.
