In recent years, as our country’s strength has continued to increase, we have all felt that the standard of living has been improving day by day. Old houses that have lived for many years will think about redecorating or buying commercial houses for decoration. The line installation generally chooses concealed installation, but because the plug power cord socket panel is uneven, it brings many unsafe factors to the residents, causing short circuits and electric shocks to occur from time to time, and some even cause fires. So how should we choose the plug power cord and socket panel?
1. The more jacks of the socket, the better?
In order to meet the needs of different types of electrical plugs, many manufacturers have designed and produced multi-hole sockets, but we blindly purchase multi-hole sockets according to our actual needs. If the number and model of the jacks do not match the electrical equipment, some jack functions are idle, which will cause waste. The technical requirements of the multi-purpose jack are relatively high. If the design is improper and the accuracy is insufficient, it is very likely that the power cord of the plug will be loose in use, poor contact, electric shock accidents, and mis-insertion.
2. The socket is three-pin, and the plug power cord is two-core.
The national standard clearly stipulates that the number of wires of the wire should be equal to the number of poles of the socket, but the power cords of some three-plug sockets currently sold on the market only have two-core wires and no grounding wires, so they cannot protect the electrical effect.
3. Inferior wires are used.
Since the qualified rate of wire products on the market is not high, do not buy them cheaply and buy inferior products to choose wire brands that meet the standards and buy them in large construction supermarkets or specialty stores. Properly reserve some power sockets to avoid plugging multiple electrical appliances into one socket panel through multi-use plugs. The power cords of some electrical appliances seem to have thick outer skins, but in fact the cores are extremely thin, much smaller than the minimum cross-sectional area specified by the standard. After power-on, the wires will heat up and easily melt the insulating rubber, which is not safe.
4. Does the length of the wire have any effect?
The length of the cable should not be too long, and the power supply should be used as close as possible; secondly, the exposed part of the cable is dangerous in the passage where people come and go. Once the line is aging or damaged by external force, it is easy to cause electric shock and injury. Therefore, it is best to install protective wire ducts in places that are easy to be touched by people. It is also dangerous to reel an overly long wire. Such long-term use will cause the cord to accumulate heat, which can easily cause a fire accident.
