PROBLEM TO BE SOLVED: To provide a power distribution board that is capable of securely making a breaker trip even when abnormal current other than overcurrent has flown in a branch circuit, and suppresses increase in the size of the board.SOLUTION: A power distribution board comprises: a plurality of breakers 4 including an external signal tripping mechanism; a measurement device 5 for measuring current information on each breaker 4; and a determination unit 6 for monitoring the measured current information. The determination unit 6 comprises: determination means for performing abnormality determination on the basis of current information input from the measurement device 5; individual identification means for identifying a breaker 4 that has been determined to be abnormal; and output means for transmitting a control signal to an external signal tripping mechanism of the identified breaker 4.SELECTED DRAWING: Figure 1 |
