Kitchen Outlet Code — Small-Appliance Circuits, Countertops & the 2023 Island Change

Kitchens carry the densest receptacle rules in the dwelling, and the 2023 NEC changed two of them in ways that surprise people: islands no longer need a receptacle, and every kitchen receptacle now needs GFCI protection.

RequirementModel Code StandardSection
Small-appliance circuitsAt least two 20-amp small-appliance branch circuits are required, and they serve the receptacle outlets in the kitchen, pantry, breakfast room and dining roomNEC 210.11(C)(1), 210.52(B)(1)
What they may serveThose circuits may not supply other outlets, with narrow exceptions for an electric clock and for equipment and lighting mounted on a gas range or ovenNEC 210.52(B)(2)
Countertop supplyCountertop and work-surface receptacles must be fed by not fewer than two small-appliance branch circuitsNEC 210.52(B)(3)
Countertop spacingEvery counter space 12 in. or wider gets a receptacle, and no point along the wall line may be more than 24 in. from oneNEC 210.52(C)(1)
MountingCountertop receptacles go on the counter surface, or not more than 20 in. above it, or in the work surface using a listed assembly; face-up installations are permitted only where listed for it and are never allowed below a sinkNEC 210.52(C)(3), 406.5(G)
Islands & peninsulasThe 2023 edition removed the requirement for island and peninsula receptacles along with the old square-footage formula. If none is installed, provisions for adding one later must be made; if one is installed it follows the countertop location rulesNEC 210.52(C)(2), 210.52(C)(3)
GFCIAll receptacles in a kitchen require GFCI protection — the 2023 edition dropped the qualifier limiting it to receptacles serving countertop surfacesNEC 210.8(A)(6)
RefrigeratorA dedicated refrigerator circuit is permitted, not required: an individual branch circuit of 15 amps or more may serve it in place of a small-appliance circuitNEC 210.52(B)(1) Exception No. 2

Worth knowing

  • The island change is the one to check twice. Under the 2020 NEC an island needed a receptacle for the first 9 sq ft and another for each additional 18 sq ft; the 2023 edition deleted the requirement outright. Which rule applies is a state adoption question.
  • Provisions for future addition is not the same as nothing. Where no island receptacle is installed, the code expects the means to add one, so plan the box and the raceway during rough-in rather than opening finished stone later.
  • The 2023 edition also eliminated the option of mounting a countertop receptacle below the counter, which had been the usual answer for an island overhang.
  • Stationary appliances now break up wall space when you measure general receptacle spacing, which changes where the required outlets land in an eat-in kitchen.
