1. A circuit interrupting device capable of being electrically connected to an electrical wiring system between line side phase and neutral conductors and load side phase and neutral conductors, the device comprising:

  • switching means for disconnecting a source of electrical power between at least the line side phase conductor to the load side phase conductor;

    trigger circuit means for causing said switching means to disconnect the source of electrical power to the load side phase conductor; and

    arc fault detecting means for detecting in said electrical wiring system arc faults occurring in a high frequency range and arc faults occurring in an AC line frequency range, and for generating a trigger signal in response to the occurrence of an arc fault in at least one of said high frequency range and said AC line frequency range that activates said trigger circuit means.
