Code Change Summary: Revisions were made expanding AFCI protection to include, kitchens and laundry areas and also to apply to devices.

In the previous 2011 NEC^®, AFCI protection was required only for 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas.

Now AFCI protection has been expanded to include 15- and 20-ampere branch circuits supplying outlets and devices installed in dwelling kitchens and laundry areas.

Another change in 210.12 is that the arc-fault circuit interrupter must be installed in a readily accessible location. Whether an AFCI type circuit breaker is used or the new outlet branch circuit type AFCI receptacle is used to provide AFCI protection for the circuit, the device providing the AFCI protection must be readily accessible.

Similarly, single phase 15- and 20-amp, 125-volt receptacles installed to serve kitchen counters and in laundry rooms must also have GFCI protection and the device providing the GFCI protection must also be readily accessible.

In many cases, electrician will be using the new GFCI/AFCI dual-function circuit breakers for these areas of a dwelling that are required to have both AFCI and GFCI protection. This will ensure that all required protection is provided and that all devices requiring monthly testing will be readily accessible.
