A system for controlling electricity consumption of an electricity consumer having a plurality of loads, including: (a) a main central processing unit, connected to a power source, and adapted to receive a signal therefrom; (b) a memory associated with the processing unit; (c) controlled relay assemblies connected to a plurality of loads via local circuit breakers, each assembly including: (i) a relay, responsive to the processing unit; (ii) a current sensor, electrically connected to the relay, the relay and the current sensor being electrically associated with the processing unit, and (iii) an electrical line having a first end connecting the relay assembly to the power source, and having a second end connecting to a local circuit breaker connected to at least one load; wherein each current sensor is adapted to provide, to the processing unit, data pertaining to current drawn via a particular local circuit breaker, and wherein the processing unit is configured to command the relay based on the signal received from the power source, and based on a set of rules provided to the processing unit, the set of rules including load priority information, such that each relay opens or closes in response to the command from the processing unit, so as to shut off or restore power to the electrical line. |
