Abstract
An arcing fault circuit interrupter testing method includes the steps of producing a simulated line to neutral arcing fault signal comprising a relatively large di/dt signal, applying the signal to a branch circuit, and producing an observable indication of operation or lack of operation of an arcing fault circuit interrupter in the branch circuit in response to the simulated line to neutral arcing fault signal. A test apparatus carries out the method.
