Kitchen outlet and GFCI planner
Under NEC 210.52(C), every kitchen wall counter 12 inches or wider needs receptacles so no point along the wall is more than 24 inches from one, roughly one every 4 feet. The 2023 NEC requires GFCI on all kitchen receptacles, with at least two 20-amp small-appliance circuits and outlets no more than 20 inches above the counter.

Enter each stretch of counter between breaks. A range, cooktop, sink or refrigerator ends one segment and starts the next. Measure along the wall line.

On wall counters, so no point is more than 24 in from a receptacle. Plus 1 island or peninsula segment to check against your code edition.

- OKGFCI protection on every kitchen receptacle (2023 NEC 210.8(A)(6); earlier editions: those serving the countertop), and on the dishwasher outlet (NEC 422.5).
- OKAt least 2 20 A small-appliance branch circuits for the counter receptacles.
- OKReceptacles no more than 20 in above the countertop; not face-up in the work surface unless it is a pop-up assembly listed for countertop use.
- CheckIslands and peninsulas: the 2023 NEC made these receptacles optional, with rules if you add them, but if you install none a provision for a future receptacle is still required. Earlier editions required at least one. Check your adopted code and inspector.
Positions are measured from the left end of each segment and spread evenly. This is a planning aid, not an electrical design: a licensed electrician and your inspector decide.

Key numbers
- Spacing rule
- No point along the counter's wall line more than 24 in from a receptacle (NEC 210.52(C)(1))
- Which counters
- Every wall counter space 12 in or wider
- One receptacle covers
- Up to 48 in of counter (24 in each side)
- GFCI
- All kitchen receptacles under the 2023 NEC 210.8(A)(6) (earlier editions: those serving the countertop); dishwasher outlets under NEC 422.5
- Circuits
- At least two 20 A small-appliance branch circuits
- Height
- No more than 20 in above the countertop; not face-up in the work surface unless it is a pop-up assembly listed for countertops (NEC 406.5(E))

- 2023 NEC 210.52(C)(2): receptacles optional, but a provision for a future one is required if none is installed
Worked example
An L-shaped counter broken by a range and a sink
36 in left of the range, 60 in between the range and the sink, 30 in right of the sink.
- 36 in: ceil(36 ÷ 48) = 1 receptacle.
- 60 in: ceil(60 ÷ 48) = 2 receptacles, evenly spaced.
- 30 in: ceil(30 ÷ 48) = 1 receptacle.
This kitchen needs at least 4 GFCI-protected countertop receptacles on two or more 20 A circuits.
How we calculate
You list each stretch of counter between breaks. A range, cooktop, sink or refrigerator ends one counter space and starts another, so each one is its own segment. For every wall segment 12 inches or wider, we count the minimum receptacles so that no point is more than 24 inches from one.
The math: one receptacle reaches 24 inches to each side, so it covers at most 48 inches of counter. A segment of length L needs ceil(L ÷ 48) receptacles. Spacing them evenly, with the first and last half a gap in from the ends, keeps every point within 24 inches. That is the same as the field formula ceil((L − 48) ÷ 48) + 1 for segments longer than 24 inches.
Islands and peninsulas are flagged, not counted, because the 2023 NEC made island and peninsula receptacles optional, with placement rules if you add them and a required provision (such as a box or raceway, as your inspector accepts) for a future receptacle if you do not, while earlier editions required at least one. This is a planning aid, not an electrical design. Your adopted code, your electrician and your inspector decide.
Estimates, sources
Planning estimates and published guidelines, not quotes, designs or code rulings. Local prices, your home and your jurisdiction's adopted code decide the real answer: get local bids and check with your inspector.

Minimum receptacles by counter length
This is the minimum for a single wall counter segment. More is fine and usually better in a busy kitchen.
| Counter segment | Minimum receptacles | Max distance to an outlet |
|---|---|---|
| 12 in (1 ft) | 1 | 6 in |
| 24 in (2 ft) | 1 | 12 in |
| 48 in (4 ft) | 1 | 24 in |

Kitchen electrical checklist for a remodel
Countertop receptacles are one part of the kitchen's wiring. Bring this list to your electrician.
- Two or more 20 A small-appliance circuits for the counter receptacles.
- GFCI protection on every kitchen receptacle (2023 NEC; earlier editions covered those serving the countertop) and on the dishwasher outlet (NEC 422.5).
- Receptacles no more than 20 in above the counter, and none face-up in the work surface unless it is a pop-up assembly listed for countertop use.
- Dedicated circuits for the range, dishwasher, disposal and microwave as the appliance manuals require.
- Island or peninsula receptacles per the code edition your area adopted; under the 2023 NEC, a provision for a future receptacle if you install none.

Questions
How far apart should kitchen outlets be?
NEC 210.52(C) requires that no point along a wall counter be more than 24 inches from a receptacle, so receptacles end up no more than 48 inches apart, with the end ones within 24 inches of each end.
Does every kitchen counter need an outlet?
Every wall counter space 12 inches or wider does. Spaces narrower than 12 inches do not need one.
Do all kitchen outlets need GFCI?
Under the 2023 NEC, yes: 210.8(A)(6) requires GFCI protection for all kitchen receptacles, not only those serving the countertop as in earlier editions. Dishwasher outlets need it under NEC 422.5. Check which edition your area has adopted.
How many circuits does a kitchen need for countertop outlets?
At least two 20 amp small-appliance branch circuits for the countertop receptacles, plus the dedicated circuits your appliances require.
Does a kitchen island need an outlet?
It depends on your code edition. The 2023 NEC made island and peninsula receptacles optional, with placement rules if you install them; if you install none, a provision for a future receptacle is still required. Earlier editions required at least one. Check your adopted code and inspector.
How high above the counter can an outlet be?
No more than 20 inches above the countertop. Receptacles cannot be installed face-up in the work surface, except receptacle assemblies listed for countertop use, such as pop-up outlets (NEC 406.5(E)).
