Abstract
By voltage sensors (CT1, CT2, and CT3), a voltage is detected in a primary side electric path (22) of a protective instrument (16) of a distribution board (11) into which commercial AC electric power is input, and secondary side electric paths (23 and 24) of the protective instrument (16) to which a branch breaker (21) is connected, respectively. Electric power is able to be supplied to the distribution board (11) side from a storage battery (13). By a control unit (33), the electric power is supplied to the distribution board (11) side from the storage battery (13) on the basis of a voltage detection by the voltage sensors (CT1, CT2, and CT3) only when the voltage is not detected in the primary side electric path (22) of the protective instrument (16).
