From the load power, the general civilian socket cable configuration load are relatively weak, the majority of nominal rated 10A; using the 1.5mm2 cable, a few manufacturers will be nominal 16A4000W, according to the national standard of the cable wire in either configuration, civil, socket rated capacity of power really hard to reach more than 4000Q. 0 - 0 wild wolves can fully meet the requirements of industrial socket. At present, the number of industrial plug current can meet the requirements of 16A, 32A, 65A, 125A and so on. Therefore, the cable socket is very wrong when using ordinary non professional socket.
