Note that the AFCI requirements have not expanded to the entire dwelling unit (to include bathrooms, basements and crawl spaces). Also, a requirement for a required exterior main shut-off for use by the fire department was defeated by the NFPA membership at the tech session last year. Although some changes were made to the AFCI section in the code, they apply only to dorms and hotels and motels.
210.8(A)(7) GFCIs Required Near Sinks
This change clarifies how to establish the measurement from a kitchen sink—the 6 ft. measurement is made from the top inside edge of the sink bowl (instead of “outside edge of the sink”). Receptacles in the cabinet below, such as for a food waste grinder, will now be excluded from the GFCI requirement. But a GFCI is still required for the dishwasher (See section 210.8(D)).
210.11(C)(4) Garage Branch Circuits
A new requirement was added to install at least one, 120 volt 20 ampere branch circuit. Applies to attached garages and to detached garages supplied with power. The circuit cannot supply lighting outlets inside or outside of the garage, but an exception permits the circuit to supply readily accessible outdoor receptacle outlets.
