ALL-LOAD POWER DISTRIBUTION BOARD AND POWER SUPPLY SYSTEM COMPRISING ALL-LOAD POWER DISTRIBUTION BOARD

To provide an all-load power distribution board for supplying power from a system and a distributed power source to loads and allowing stable operation by combination with a power supply device.SOLUTION: An all-load power distribution board comprises: an automatic change-over switch that switches between a first input terminal for power input from a system and a second input terminal for power input from a distributed power source for connection to an output terminal for output to loads; and a first terminal block and a second terminal block that are disposed in a cable way connecting the system and the first input terminal. The first terminal block has a first terminal connected to a first commercial power line connected to the system, and a second terminal connected to a first distributed power source connection line connecting the distributed power source and the system and to a second commercial power line connecting the first and second terminal blocks. The second terminal block has a third terminal connected to the second commercial power line, and a fourth terminal connected to a third commercial power line connecting the second terminal block and the first input terminal. A first power supply line for supplying power from a power supply device can be connected to the third or fourth terminal.SELECTED DRAWING: Figure 1 【課題】系統及び分散電源から負荷に電力を供給し、電力供給装置を組み合わせて安定的に稼働可能な全負荷用分電盤を提供する。【解決手段】系統の電力が入力される第１入力端子と分散電源の電力が入力される第２入力端子とを切り替えて負荷に出力する出力端子に接続する自動切替開閉器と、系統と第１入力端子とを接続する電路に配置された第１端子台及び第２端子台と、を備えた全負荷用分電盤であって、第１端子台は、系統に接続された第１商用電力線が接続される第１端子と、分散電源と系統とを接続する第１分散電源接続線と、第１端子台と第２端子台とを接続する第２商用電力線とが接続される第２端子とを有し、第２端子台は、第２商用電力線が接続される第３端子と、第２端子台と第１入力端子とを接続する第３商用電力線が接続される第４端子を有し、電力供給装置から電力を供給する第１電力供給線が第３端子又は第４端子に接続可能である。【選択図】図１
