Understand the benefits of the distribution box installation

There are two kinds of installation of distribution box, one is surface installation, the other is flush installation. The surface installation is directly nailed to the wall, and the incoming and outgoing wires are also exposed pipes. The flush distribution box is lying inside the wall, and the incoming wires are also buried. Generally speaking, the household distribution box will be installed in some places convenient for use and maintenance, so that the maintenance personnel can open the switch at any time to repair the line. However, the installation position should not be too obvious as far as possible. It can be covered by a decoration. The size of the distribution box is determined by the number of shunt air switches. This also has a higher level of safety protection, and can visually display the conduction state of the circuit.
