Basic knowledge of power socket installation:
1, socket installation, open the socket from the ground should not be 1.8 meters. Industrial plug is suitable for industry, generally divided into 3 core, 4 core, 5 core, etc., current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., protection grade can be divided into IP44, IP67 these two, for these are more conventional. In general, it is used with industrial sockets and industrial connectors. CEE connectors CEE standard industrial plug receptors. they are explosion-proof receptors. the temperature is limited to 32 degrees. Power socket has one or more circuit wiring can be inserted into the seat, through it can be inserted into a variety of wiring, easy to connect with other circuits.
