1. An apparatus for testing arcing fault interruption protection of a branch circuit, comprising:

  • arcing fault signaling means for producing a simulated line to neutral arcing fault signal and a simulated line to ground arcing fault signal;

    means for separately selecting said simulated line to neutral arcing fault signal and said simulated line to ground arcing fault signal;

    plug in connector means for removably connecting the tester apparatus to a branch circuit so as to apply the selected signal to said branch circuit;

    indicator means coupled in circuit with said connector means and responsive to presence or absence of a line voltage across said branch circuit for producing an observable indication of operation or lack of operation of an arcing fault circuit interrupter in said branch circuit in response to each of said simulated line to neutral arcing fault signal and said simulated line to ground arcing fault signal; and

    a relatively small, portable hand-held housing for enclosing said tester apparatus, said connector means being coupled with said housing.
