Last known
trip condition Troubleshooting1 2
Off Off Overcurrent
Ensure current on the circuits does not exceed the current rating for
the breaker.
On Off Arc fault
Check wiring for the parallel and series arc faults. Check devices for
series arc faults. Use Intelli-Arc to assist and accelerate diagnosis.
On On Art fault to ground
Check wiring, switches, and receptacles for possible ground leakage.
Use Intelli-Arc or circuit tester to troubleshoot. Using safe electrical
practices, systematically identify the source of the ground fault.

trip condition Troubleshooting1 2 3
Off Off Off Overcurrent
Ensure current on the circuits does not exceed the current rating for
the breaker.
On Off Off Arc fault (leg A)
Check wiring for the parallel and series arc faults. Check devices for
series arc faults. Use Intelli-Arc to assist and accelerate diagnosis.
Off Off On Arc fault (leg B)
On On On Art fault to ground
Check wiring, switches, and receptacles for possible ground leakage.
Use Intelli-Arc or circuit tester to troubleshoot. Using safe electrical
practices, systematically identify the source of the ground fault.
Additional questions to ask
when troubleshooting:
1) How many LED’s on the breaker upon reset?
2) What event/action is causing the trip condition?
3) Has the event/action for the trip condition been identified?
4) Which circuits are experiencing the trip condition?
5) What devices are on that circuit?
