Claims (1)

[Scope of utility model registration request] A large number of unit devices that are removably housed in a box and are made up of main circuit devices such as disconnectors, electromagnetic contactors, and monitoring/control devices grouped into unit circuits, and between each of these unit devices and the main bus bar. a load disconnector provided between each unit device and each load, a temporary power supply connection terminal provided in each unit device, and the load disconnector are disconnected. A control center comprising a connection terminal fitting interposed between a movable contact and a fixed contact of the load disconnector in a state where the load disconnector is in a state where the load disconnector is in a state where the load disconnector is in a fixed state and electrically connects the two.
