<p>A method and apparatus for testing an AFCI device. In one embodiment, the method comprises the steps of providing an AFCI device to be tested and a load, wherein the AFCI device and the load form an electrical circuit, applying AC power to the AFCI device, generating (138) a high frequency broadband noise signal, amplifying (142) the high frequency broadband noise signal to provide an amplified high-frequency noise signal, modulating (150) the amplified high frequency noise signal with a signal synchronized to the load current or load voltage to provide synchronized high frequency broadband noise bursts, coupling (120) the synchronized high frequency broadband noise bursts into the electrical circuit to simulate series arcing signals, determining (114) if the AFCI device opens the electrical circuit within a predetermined amount of time, indicating (132,134) the AFCI device has passed the test if the AFCI opens the electrical circuit within the predetermined amount of time, and indicating the AFCI device has failed the test if the AFCI device fails to open the electrical circuit within the predetermined amount of time.</p> |
