Abstract
An electrical system includes a first circuit breaker that digitally senses a first current to a first load, and a second circuit breaker that digitally senses a second current to a second load and provides an output to the first circuit breaker. The first circuit breaker determines an average current based upon the first sensed current and the output from the second circuit breaker, and the first and second circuit breakers terminate power to the first and second loads if the average current is greater than a threshold value.
