CUSTOMER CASE
In a nutshell, according to the standard, all portable electrical appliances with Class I protection, such as electric irons, water boilers, electric heaters, and electric lamps, also include all kinds of table lamps, electric kitchen appliances, washing machines, refrigerators, etc. It is strictly forbidden to use connecting wires with safety plugs (plugs with protective grounding contacts), and do not use ordinary two-pole lighting plugs.
The reason for this requirement in the standard is that the simultaneous use of the safety ring and the lighting plug is actually just a stopgap measure, and it is bound to cause a lot of trouble. As everyone knows, the two-pole lighting plug cannot be inserted into the safety ring (the ring with protective grounding contact), and now it is stipulated that all the indoor safety rings are used. Therefore, all kinds of mobile electrical appliances must be capable and safe. Matching plugs for the ring.
On the other hand, considering that standby mobile electrical appliances can also be used in old-fashioned building electrical installation systems, because in this system, all rooms in the building are equipped with ordinary sockets, so the safety sockets must be able to be inserted The safety sockets with protective grounding contacts can also be broadcast into the cradles without protective grounding contacts that meet the requirements of the standard.
Unfortunately, old sockets with 4mm pin plugs are also commonly used so that safety plugs can be inserted. It is completely wrong to replace safety plugs with ordinary lighting plugs. The old-fashioned sockets must be replaced with safety sockets that meet the requirements of the standard, that is, with protective grounding contacts.
Of course, you must bring a protective wire, which is a protective measure prescribed by the standard. A variety of novel safety plugs with protective grounding contacts, electrical sockets with protective grounding contacts, and multi-head sockets with protective grounding contacts that comply with standards can be seen in the market.
