Hereinafter, in more detail with respect to each component, the base plate 10 is the same while ensuring the space portion 11 through which the first and second bus bars 40 and 50 cross in the vertical and horizontal directions. It consists of a combination of a plurality of plates of thin thickness that are combined in a horizontal and vertical crisscross direction on a plane.

The base plate 10 is formed of a combination of three to four plates placed on one same plane, thereby forming a space portion 11 having a substantially quadrangular shape in the center.

At this time, a space through which the busbars, in particular, the first and second busbars 40 and 50 can pass, is secured by the space 11.

The base plate 10 is preferably manufactured to have a substantially "c" shaped cross section, which ensures a predetermined clearance space with the installation bottom surface, thereby securing a passage through which a bus bar or an electric wire can pass using the clearance space. You will have the advantage of

In addition, the base plate 10 is preferably made of a flame retardant material, which is to minimize the risk of fire due to overload or spark.

The main circuit breaker 20 provides power to various electrical loads, and is fixedly installed on a base plate 10 disposed vertically upward, and includes a plurality of first busbars that traverse the space 11 in the longitudinal direction. 40 is electrically ground coupled.
