Claim:
1. A management apparatus comprising: a wireless module configured to communicate wirelessly with an electrical appliance and distribution board connected over a network; a non-transitory computer-readable recording medium storing a program; and a hardware processor that executes the program and causes the management apparatus to operate as: a measurement unit configured to measure a value of power supplied from an electrical outlet to the electrical appliance as measured at the distribution board during a predetermined period; a first acquisition unit configured to acquire identification information for the electrical outlet and power supply information for the outlet from the distribution board, the identification information for the electrical outlet identifying the location of the outlet and the power supply information being a value of power supplied by the outlet to the appliance as measured at the distribution board during the predetermined period; a second acquisition unit configured to acquire from the electrical appliance identification information for the electrical appliance and power consumption information, the electrical appliance information identifying the type of appliance and the power consumption information indicating a value of power consumed by the electrical appliance during the predetermined period, the value of power consumed being output by the electrical appliance and measured by a measurement device in the electrical appliance, and determined concurrently with the power measured from the electrical outlet during the predetermined period; a comparison unit configured to compare the acquired power supply information for the outlet with the acquired power consumption information for the electrical appliance for determining a concordance rate between the power supply information and the power consumption information, the concordance rate being determined by comparing the value of the power supplied by the outlet to the appliance and the value of the power consumed by the electrical appliance at a point in time during the predetermined time period; a generation unit configured to generate information indicating an association between the electrical appliance and the electrical outlet using the identification information for the electrical outlet and the identification information for the electrical appliance when the concordance rate between the power supply information and the power consumption information exceeds a threshold value according to a result of the comparison; and a storage unit configured to store the association information between the electrical appliance and the electrical outlet, the association information indicating an installation location of the electrical appliance in the electrical outlet during the predetermined period, wherein the wireless module outputs the association information between the electrical appliance and the electrical outlet to an external display device that displays the association information between the electrical appliance and the electrical outlet.
