Abstract
Abstract An energy-efficient device for managing residential loads on electrical generating systems is disclosed. The device is suitable for installation in existing circuit breaker load center panels at low labor costs, to be signalled from Load Management System(s), of various types. The device of the present invention causes the circuit breaker to disconnect and reconnect thereby controlling power consumption during peak periods of energy use. Various alternative embodiments are also disclosed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
A device for managing consumer demands for electricity comprising means adapted for connection to a voltage supply, means adapted for connection to a load, energy storage means having a predetermined amount of energy stored therein, impulse sensing means not requiring constant energization, first switch means responsive to a command signal for connecting said energy storage means to said impulse sensing means for a predetermined period of time, second switch means having two states and actuated by said impulse sensing means when said energy storage means is connected to said impulse sensing means for connecting said voltage supply to said load when said second switch means is in a first state and disconnecting said voltage supply from said load when said second switch means is in a second state.
Claim 2
Independent Claim
128 words
A device for managing consumer demands for electricity comprising means adapted for connection to a voltage supply, means adapted for connection to a load, energy storage means having a predetermined amount of energy stored therein, impulse sensing means not requiring constant energization, first switch means responsive to a command signal for connecting said energy storage means to said impulse sensing means for a predetermined period of time, second switch means having two states and actuated by said impulse sensing means when said energy storage means is connected to said impulse sensing means for connecting said voltage supply to said load when said second switch means is in a first state and disconnecting said voltage supply from said load when said second switch means is in a second state.
Claim 3
Dependent Claim
120 words
In a circuit breaker adapted to be installed in a standard sized service panel and having a plurality of sensing elements for sensing circuit overloads, first terminals for connection to a voltage source and second terminals for connection to a load, the improvement comprising third terminals adapted to receive a command signal, control means including switching means not requiring constant energization connected to said third terminals and responsive to the command signal to disconnect said load from said voltage source when said command signal is in a first state and to connect said load to said voltage source when said command signal is in a second state, said disconnecting and connecting being independent of the state of said sensing elements.
Claim 4
Dependent Claim
120 words
In a circuit breaker adapted to be installed in a standard sized service panel and having a plurality of sensing elements for sensing circuit overloads, first terminals for connection to a voltage source and second terminals for connection to a load, the improvement comprising third terminals adapted to receive a command signal, control means including switching means not requiring constant energization connected to said third terminals and responsive to the command signal to disconnect said load from said voltage source when said command signal is in a first state and to connect said load to said voltage source when said command signal is in a second state, said disconnecting and connecting being independent of the state of said sensing elements.
