Claims

[Scope of utility model registration request]

A closed switchboard for opening/closing and protecting a bus bar, which opens/closes the bus bar of a unit group formed by connecting a plurality of first closed switchboard units housing circuit breakers for opening/closing the bus bar, and the closed switchboard units; and a second closed switchboard unit housing a busbar connecting breaker that is installed in a normal installed state of the breaker housed in the closed switchboard unit or in a state where it is laid down from the normal installed state, and the busbar connecting breaker; A closed power distribution board characterized in that it is equipped with moving wheels that are installed on a surface that becomes the bottom when the power switchboard is laid down on its side.
