At the construction site, it is often seen that workers do not meet the site construction safety specifications when using civilian power sockets for polishing machines or other work. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. A switch is arrange between that resistance of the weatherproof socket and the electromagnetic switch; the fuse and the electromagnetic switch are connected with a pow line; the power line is provided with an electromagnetic switch normally open switch which is connected with a jack. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted, so as to facilitate connection with other circuits. From the perspective of manufacturing safety, industrial plugs must be used in industrial production engineering construction, and use safety must be strictly enforced.Why should industrial plugs be used in engineering construction, but not civil wiping power sockets? The first kind of civil socket plug has no safety measures, and it is easy to cause safety accidents of power failure and damage when it is pulled out many times. Even if the power socket box shell fails, it is still in use, and the cold and humid temperature can easily cause near electric shock accidents, and sometimes it can cause inductive electrification of the shell and damage the staff of the switch box. The key of civil power socket is made of hard plastic shell, and the bracket is too large to be damaged easily.To put it bluntly, industrial plug is the application of industrial plug in industrial production. Industrial electricity is electricity, which is different from civil single-phase electricity, and the final power socket structure is also different. Industrial plugs and sockets have moisture-proof and pollution-proof functions, which can prevent all kinds of dirt, dust or water from splashing into the plugs and sockets, and ensure the normal supply of power engineering under extreme standards. Industrial plug is an essential control system in various construction sites. The shell is made of hard plastic and covered with a soft cover, so that the human body cannot touch the contacts.
