Misunderstanding one: 3 feet DC socket with low azimuth
Too many families feel too high when they install the sockets, which hinder the Peugeot and will be installed in the lower shade position. But Dr Xia Dong, an electrical Research Institute of the Chinese Academy of Sciences, declared that it was so simple that when water was mopped up, the water was splashed into the socket, causing electrical leakage. In the industry, the best sockets are not less than 1.8 meters from the ground, and the sockets should not be less than 0.3 meters above the ground.
