Abstract

An apparatus for testing an arc fault circuit interrupter includes an AC signal generator circuit configured to be capacitively coupled to an AC power line and to induce an AC signal thereon and a control circuit configured to control the AC signal generator circuit to selectively enable and disable generation of the AC signal responsive to a waveform of an AC power voltage of the AC power line.
