Abstract
A method for identifying a type of fault condition in a circuit breaker includes monitoring a branch circuit for a fault condition. In response to detecting the fault condition, interrupting current flow through the branch circuit. The type of fault condition is stored in a memory device from which it is retrieved in response to receiving a control signal. The type of fault condition is indicated based on the mechanical position of a circuit breaker handle as a function of time.
