Summary:The disclosed methods and systems employ a nonprobability-based detection scheme that measures conditions (e.g., voltage or current) at multiple locations on a circuit, such as a branch circuit, to detect for a presence of an arc fault condition. A centralized processing system, such as a controller (120), receives information corresponding to a branch origin voltage or current measurement sensed by a sensor (114, 116) at a branch origin upstream of the plurality of end-use devices (150) on the branch circuit (e.g. at a circuit breaker defining the branch), and receives information corresponding to a downstream voltage or current measurement at each of the end-use devices sensed by a corresponding downstream sensor (152, 154).
