Abstract

Claims (10)

1. A circuit breaker formed to interface with at least one power rail of an electric service panel, the circuit breaker comprising:

a first input to monitor a total present electric current consumption value for a plurality of electric consumers served by the service panel and not served by the circuit breaker;

logic to compare the present electric current consumption value with a preset maximum current capacity limit;

a second input to receive electric current from the service panel;

an output to supply electric current from the first input to an electric consumer;

logic to set an electric charging current drawn from the service panel through the second input and provided to the output to a value less than a difference between the maximum current capacity limit and a sum of the total present electric current consumption value and a preset current consumption value for an electric consumer coupled to the service panel but that is presently not drawing current.

2. The circuit breaker of claim 1 , further comprising:

the electric consumer is a group of more than one electric consumers that are expected to be drawing current at the same time, based on one or more of the time of day or day of the week.

3. The circuit breaker of claim 1 , further comprising:

logic representing an offset amount of current reflecting a location of the circuit breaker along the power rail of the service panel, the offset amount representing an amount of current used by electric consumers served by breakers above the circuit breaker on the power rail.
