PROBLEM TO BE SOLVED: To provide a management device for power consumption capable of reducing useless power consumption of an electronic apparatus that is operated by receiving single-phase AC output from a three-phase four-wire AC power source, a management method and a management program.SOLUTION: A management device 20 for power consumption is provided for an electronic apparatus to which power is supplied from an outlet box that is connected to a three-phase four-wire AC power source by single-phase output based on a first phase among three phases, single-phase output based on a second phase that is different from the first phase among the three phases, or single-phase output based on a third phase that is different from the first phase and the second phase among the three phases. The management device for power consumption comprises: total power consumption calculation means 24 for calculating a total of power consumption values of the electronic apparatus receiving power supply for each of the three phases; power consumption difference calculation means 25 for calculating a power consumption difference among the three phases, based on the calculated total of the power consumption values; and instruction means 27 that instructs an operation of the electronic apparatus, based on the calculated power consumption difference.SELECTED DRAWING: Figure 1 |
