Abstract

A system to stop or reduce electrical short circuits in homes. This invention is a refinement of the breaker box function. A computer controls breaker switching in the breaker box. A sum of the theoretical power consumption in a given breaker helps the computer determine if an electrical short is present. Outlet modules attach themselves to the home'"'"'s standard electrical outlet (socket). They tell the computer when a new load (finite resistance) is to change the old theoretical breaker limit. The computer adjusts the theoretical limit to a new limit (never above maximum permitted) and allows the power drain on the breaker.

Claims

1. An adaptive-control circuit breaker system, comprising:

first circuit breaker means responsive to a control signal for opening a first electrical circuit having a plurality of electrical outlets connected thereto;

electronic control means for electronically controlling said first circuit breaker means, said control means including means for generating said control signal in response to electrical current flowing through said circuit in excess of a breaker limit set for said first circuit breaker means, said electronic control means including means for automatically adjusting said breaker limit in response to load conditions;

and means for determining present load conditions at each of said outlets.

2. The system of claim 1, wherein said determining means includes means for detecting the presence of an electrical device connected to one of said outlets and for sending an enabling signal to said electronic control means to enable increasing said breaker limit.

3. The system of claim 2, further comprising a plurality of outlet electronic switch means for selectively connecting respective individual outlets to said circuit,

wherein said electronic control means includes means for holding each said outlet electronic switch means open to disconnect its respective outlet from said circuit until said device presence is detected and said enabling signal is sent to said electronic control means.

4. The system of claim 3, wherein said determining means includes means for learning the load requirement of an individual load, said system further comprising a plurality of means remote from said electronic control means for selecting a learning mode during which said learning means operates.
