PROBLEM TO BE SOLVED: To collectively control energization of a plurality of pieces of electrical equipment without forcing a user to pull out a plug from a socket or to operate a branch breaker directly.SOLUTION: A collective closing device 1 is disposed next to a distribution board 4 housing a plurality of branch circuits 21, 22, to 2n and a plurality of branch breakers 31, 32, to 3n corresponding to the respective branch circuits, in a board body 41. The collective closing device 1 is provided with a contact device 11, and a switching device 12 which switches the state of the contact device 11 between the open state and the closed state. The contact device 11 is inserted between the nth branch breaker 3n among the plurality of branch breakers 31, 32, to 3n, as an object breaker, and the nth branch circuit 2n corresponding to the nth branch breaker 3n, as an object circuit. |
