Abstract
Certain exemplary embodiments comprise a method, which can comprise automatically generating an output signal responsive to an input signal. The input signal can be indicative of an arc fault. The output signal can be configured to cause an electrical circuit to open. The output signal can be generated responsive to a derived signal based upon a first threshold having a first amplitude.
