1. An equipment power management system comprising:

  • a plurality of electrical devices having multiple operational states different from each other in power consumption of a commercial power source, each electrical device operable in an operational state of the multiple operational states; and

    a control device including;

    a comparator to compare a receiving power amount of the plurality of electrical devices to a first threshold value and to a second threshold value lower than or equal to the first threshold value;

    a switch to switch the operational states of one or more electrical devices to that of a smaller power consumption in ascending order from the electrical device of a lowest priority when the comparator determines that the receiving power amount exceeds the first threshold value until the comparator determines that the receiving power amount falls below the second threshold.
