PROBLEM TO BE SOLVED: To provide an electric energy-integrating apparatus and a distribution board in which a plurality of branching circuits to be measured are stored in a casing of a relatively small outer shape and which can measure an integral power consumption of each circuit. SOLUTION: There are provided a current transformer 5 for detecting a conduction current of the branching circuit B to be measured which branches from a main circuit A, a power-detecting means 6 to which an output of the current transformer 5 and a voltage output of the main circuit are inputted and which operates and integrates a consumed power and outputs pulses every time the integral power consumption value becomes a predetermined unit value, and a count display means 7 for counting inputted pulses from the power- detecting means 6 and displaying the counted integrated value. |
