2023 NEC 210.52(C)(3) requires kitchen countertop receptacles to be on or above the counter, not more than 20 in (500 mm) above it; a face-up receptacle in the surface is allowed only if listed for countertop/work-surface use. Below-counter mounting (formerly permitted up to 12 in below) was removed in the 2020 NEC, and there is no allowance for face-up within 6 in of the edge or placement in the upper cabinet.
