Question:

I am replacing a direct wired garbage disposal with a plugin disposal. Do I need to install GFCI outlet or can I use just a grounded outlet?

Answer:

Hey Michael thanks for your question. In dwelling unit kitchens only, the 125 volt single phase 15 and 20 ampere receptacles that serve counter top surfaces need to have GFCI protection as stated in 210.8(A)(6). Also, dwelling unit receptacles, with those ratings, that are within 6 ft of the top inside edge of sink bowls in any areas need GFCI protection as stated in 210.8(A)(7). A new second paragraph in 210.8 indicates that the cord distance is shortest path without piercing any of the items stated. So grounding type receptacles are required as stated in 406.4(A) but GFCI protection is not required for the receptacle you describe.
