Kitchen receptacle count and GFCI rules.
What it does
Kitchen counters hide an electrical rhythm: receptacles every 4 feet so no appliance stretches past 24 inches to power. Islands earn their own box besides.
The tool above takes wall counter feet with island choice. It returns receptacle count with GFCI and spacing rules.
The default 12 ft without island needs 3 receptacles at 48 in max apart, GFCI protected. The 8 ft case needs 2, and islands add one more.
Electrical code resources set the spacing with GFCI protection for kitchen small appliance circuits. Safety guidance repeats the counter and island counts for planning.
Counts plan boxes; electricians place them to studs, sinks, and ranges. Tamper resistant devices with correct circuits complete the safe kitchen.
How to use
- Type wall counter feet.
- Pick island or not.
- Read receptacle count first.
- Read GFCI beside it.
- Read spacing last.
- Place boxes with electricians.
Formula
- counter
- Wall counter length in feet.
- island
- Island or peninsula present.
NFPA electrical code resources carry NEC receptacle spacing with GFCI protection for kitchen counters. Electrical safety guidance mirrors the same counter and island rules for planners. Counts here plan boxes; framing and local amendments decide final placement.
Worked example
Example: 12 ft of counter
Defaults: 12 ft counter, no island.
- Counter: 12 ft of wall counter, no island.
- Count: ceil(12 / 4) = 3 receptacles.
- Spacing: 48 in maximum apart.
- Protect: GFCI protection required.
- Island: adds one more receptacle.
- Tool shows 3 receptacles, GFCI protection required, 48 in max apart.
Reference table
| Counter | Count | Note |
|---|---|---|
| 8 ft | 2 | No island |
| 12 ft | 3 | No island |
| 20 ft + island | 6 | Island adds 1 |
| 16 ft | 4 | No island |
Limits
- Planning counts, not permits.
- Framing moves real boxes.
- Ranges and sinks break runs.
- Local amendments can exceed.
Common mistakes
- Stretching cords past 24 in.
- Skipping island boxes.
- Forgetting GFCI near water.
- Counting behind ranges.
- Any circuit will do thinking.
Try it yourself
Quick checks. Answers sit tucked under each question.
8 ft, no island?
2 receptacles, GFCI, 48 in max apart.
20 ft with island?
6 receptacles with the island extra.
0 ft?
Under a foot counts nothing plannable: enter 1 to 200.
Questions
Spacing rule?
One per 4 ft of counter, so no point sits over 24 in from a receptacle. Islands need at least one.
GFCI?
Yes, kitchen receptacles need GFCI protection against shocks near water.
What counts?
Counter 12 in plus wide counts; behind range and sink gaps break runs.
Any circuit?
No, small appliance branch circuits serve kitchens and dining with limited exceptions.
Tamper resistant?
Yes, tamper resistant receptacles guard curious fingers in homes.
Permit design?
No, this plans counts. Electricians place boxes to framing and code cycles.
