    Default Eaton AFCI - Blinking Red Light

    Can anyone inform me what the small red light directly next to the test button indicates on the Eaton AFCI breakers? This light started blinking after a tripped breaker was reset.

    Blinking is Error Code.

    Look at PDF for code reference to blinking

    http://www.crestron.com/downloads/pd...al/clb-120.pdf

    0 Mechanical Disconnect -The breaker has detected an
    overload, short circuit, or was manually turned off.

    1 Current Arc - A low current “series” arc has been
    detected within one of the current pathways. These arcs
    are typically found in worn or degraded appliance and
    extension cords, poor connections in appliances or
    fixtures, or in contacts within equipment.

    2 High current Arc - A high current “parallel” arc has been
    detected between two conductors. These arcs are usually
    found in installed wiring where the wire has been
    compromised by a nail or screw, an over tightened staple,
    or damaged insulation

    3 Short Delay - Short delay is an electronic backup to the
    short circuit mechanism.

    4 Overvoltage - A voltage of 160V RMS or greater has been
    detected. After resetting the breaker, press the “TEST”
    button to verify the breaker is working properly.
    5 Ground Fault - The breaker has detected that current has
    found an alternate path to ground.

    6 Self Test Failure - The breaker continually tests its internal
    electronics and software to ensure the arc fault detection
    technology is working properly. The breaker will trip in the
    event of a self test failure

    I experienced this today. Two of the three AFCI breakers would not trip. Since the house was vacant I turned them off and on again. The red light blinked in the 6 blink pattern, but they still would not trip. As I read the wording it sound like they are supposed to trim themselves if the self-test fails. They did not.

    I've run into this too. Sometimes, they briefly blink then stop. Newer AFCIs seem more reliable, but I had a new one fail to reset a few weeks ago.

    If you choose not to decide, you still have made a choice.
