The National Electric Code (NEC) has required both GFCI and CAFCI protection for laundry and kitchen circuits in a residence since the 2014 edition of the code. There are two ways you can do it:

1. Install a Dual Functional Circuit Interrupter (DFCI)breaker, shown above, in the electric panel for the circuit. It provides both GFCI and CAFCI protection, along with the overcurrent protection of a standard circuit breaker. To read more about them, see our blog post ”What is a Dual Function Circuit Interrupter (DFCI)?” 
2. Install a CAFCI breaker for the circuit in the panel and a GFCI-receptacle at the first outlet in the circuit, which will provide GFCI-protection for all the downstream receptacles.

    The cost of the equipment is about the same for either type of installation, but #2 makes it easier troubleshoot whether the defect causing a trip was an arc fault or a ground fault in the circuit.
