HOME DISTRIBUTION BOARD

PROBLEM TO BE SOLVED: To provide a home distribution board capable of obtaining the sufficient switching lifetime even while including a function capable of opening/closing a cable rub arbitrarily for standby power reduction.SOLUTION: A home distribution board comprises: a main switch 101; a branch switch 102; an abnormality detection part 103 which detects abnormality of a load circuit and outputs a first circuit switching signal; an artificial operation receiving part 105 which detects an artificial operation for standby power reduction and outputs a second circuit switching signal; and a control part 106 which receives the circuit switching signal and sends a branch switching signal to the branch switch. The branch switch controls power supply to the load circuit by a semiconductor relay which switches a cable rub when the branch switching signal is received.SELECTED DRAWING: Figure 1 【課題】待機電力軽減の為に任意で電路を開閉可能な機能を有しても充分な開閉寿命を得られる住宅用分電盤を提供する。【解決手段】主開閉器１０１と、分岐開閉器１０２と、負荷回路の異常を検出し第一の回路開閉信号を出力する異常検出部１０３と、待機電力軽減の為の人的操作を検出して、第二の回路開閉信号を出力する人的操作受付部１０５と、回路開閉信号を受け、分岐開閉器に分岐開閉信号を送る制御部１０６と、を備え、分岐開閉器は、分岐開閉信号を受けた時に電路を開閉する半導体リレーで負荷回路への電力供給を制御する。【選択図】図１
