If Arc Fault and Ground Fault are required on the same circuit, it is ok to just use the Arc Fault breaker?

Product Line:
QO and HOM Arc-Fault, Ground-Fault, and Dual-Function Circuit Breakers
  • Arc Fault - breaker suffix AFI, CAFI, PCAFI
  • Ground Fault - breaker suffix GFI
  • Dual Function - breaker suffix suffix DF, PDF

Resolution:
No. If both Arc Fault and Ground Fault protection are required on the same circuit, it is not ok to just use the Arc Fault breaker. The reason is that the Arc Fault breaker does not provide Class A GFI Ground-fault protection (personnel). If both Arc Fault and Ground Fault are required on the same circuit, consider using the Dual Function Circuit Breaker. The Dual Function breaker includes both Arc Fault and Class A Ground Fault protection for people, all in the same breaker.
