摘要

PROBLEM TO BE SOLVED: To provide an electric measuring instrument capable of measuring the supplied quantity of electricity supplied for each electric apparatus from a plurality of branch breakers in a distribution panel and reducing the space of its installation location.

SOLUTION: The electric measuring instrument 200 can measure the supplied quantity of electricity supplied for each electric apparatus from the plurality of branch breakers 150A-150D in the distribution panel. The electric measuring instrument 200 includes electric measuring parts 10A and 10B and a matrix switch 60. The electric measuring parts 10A and 10B measure each quantity of electricity supplied from each of the branch breakers 150A-150D and are of a number smaller than the number of the branch breakers 150A-150D. The matrix switch 60 is arranged between the branch breakers 150A-150D and the electric measuring parts 10A and 10B and can change over an object to be measured between the electric measuring parts 10A and 10B.
