ABSTRACT:
A power distribution board includes a blind cover and main and shunt interrupters. A blind cover has an engaging tab disposed at one end for engaging an edge of the window, and a foldable engaging tab at the other end of the blind cover main body. The foldable tab holds, in cooperation with the engaging tab, the blind cover to the distribution panel board cover. The shunt circuit interrupters are mounted in a side-by-side relationship with an insulating partition wall interposed therebetween. The partition wall is accommodated within recesses in the side surfaces of the interrupters, so that dielectric breakdown does not ocur around the gas exhaust ports. One side of the main circuit interrupter is secured to a base plate by the rigidity of a connecting conductor while the other side of the interrupter is secured in a usual manner. The insulating mounting base for the shunt circuit interrupter has a projection and the shunt conductor has a recess formed therein for engaging with the projection, whereby the insulating mounting base is secured to the base plate by the rigidity of the shunt conductor.
