A
Answer:
Hey Stephen thanks for your question. Dwelling unit single phase 125 volt receptacles that are 15 or 20 ampere must have GFCI protection for personnel if within 6 ft of the top inside edge of a sink bowl as stated in 210.8(A)(7). The additional second paragraph of 210.8 in the 2017 NEC indicates that the measurement is made based on a cord path that does not pierce a barrier or pass through a doorway. A receptacle in a dwelling unit kitchen cabinet does not need GFCI protection because the cord would need to pass through the doorway. Waste disposers are not included in 422.5 so do not require GFCI protection unless it is included in the listing instructions as stated in 110.3(B).
