Can GFCI and AFCI be on the same circuit?
Tuesday, February 25, 2020
Yes, GFCI and AFCI can be on the same circuit. In fact, some circuits are now required to have both. Kitchens and laundry rooms were added to the list of circuits required to have AFCI protection in the 2014 edition of the National Electrical Code (NEC), and they were already required to be GFCI-protected.
Circuits can be AFCI/GFCI protected several ways: by a GFCI-breaker in the panel and AFCI-receptacle at first outlet in the circuit, or AFCI-breaker and GFCI-receptacle at first outlet in circuit, or there is also a Dual Function Circuit Interrupter (DFCI) available that provides both types of protection in one circuit breaker.
Also, see our blog posts What is a Dual Function Circuit Interrupter (DFCI)? and When were GFCI receptacle outlets first required? and When did arc fault circuit interrupter (AFCI) breakers first become required?
