According to this answer, all receptacles in a kitchen that serve a countertop surface must be GFCI protected.
Which Kitchen outlets do NOT need GFCI?
I already replaced the outlets next to the sink with gfci and will now replace an outlet located on the opposite side of the kitchen sink, so my understanding is that I must replace with a gfci (and tamper resistant too?). I have no problems following code, but I'd rather understand the reasoning behind code. Why does this receptacle need to be gfci protected if it is far away from the sink?
