Abstract
An equipment power management system in accordance with the present invention has a plurality of electrical devices and a control device. The electrical devices can operate in any one of multiple operational states different from each other in power consumption of a commercial power source. The control device switches the operational state of an electrical device to that of a smaller power consumption of the commercial power source in ascending order from the electrical device of the lowest priority when a receiving power amount of the whole equipment including the plurality of electrical devices exceeds a first threshold value until the receiving power amount falls below a second threshold value which is lower than or equal to the first threshold value.
