PROBLEM TO BE SOLVED: To provide a power feeding management system capable of interlocking on/off operations of power supply between devices connected with different power supply taps.SOLUTION: Each master tap MT1, MT2 comprises: master power amount measurement means that can measure a power consumption amount of a device connected to each master outlet MC1, MC2; master power amount determination means that can determine whether or not the measured power consumption amount becomes larger than a preliminarily-determined threshold; and transmission means that can transmit the power determination result by the determination means toward each expansion tap ET1, ET2. Each expansion tap ET1, ET2 comprises: reception means that can at least receive the power determination result transmitted by the transmission means; expansion tap power control means controlling a power supplied from each dual-purpose outlet SC1, SC2 depending on the received power determination result; and switching means that can switch each dual-purpose outlet SC1, SC2 to any one of a slave outlet and a normal outlet. Thereby, power feeding is managed. |
