An energy management system for controlling a plurality of electrical loads having assigned priorities of use employs electronic relays to sense the flow of current in the loads. Signals from the electronic relays are used by power relays or by a combination of control relays and power relays to disable selected electrical loads. An additional control relay can be employed to prevent disabling of a selected load. A repeat cycle time delay relay can be employed to alternate disabling of selected loads.
