Precautions in operation of low voltage distribution box (2)

2. The arrester is only installed on the incoming line side, and the lightning protection cannot cover the whole equipment

Usually, fuse and other equipment are installed between the incoming and outgoing lines of the distribution box and its bus. When the outgoing line is struck by lightning, if the incoming fuse is blown first, all the distribution boxes will lose the lightning protection. Many distribution boxes are damaged by lightning every year.
