Outlets Needed vs Total Wall Length
NEC Outlet Spacing (210.52)
The NEC requires that no point along a wall be more than 6 feet from an outlet. This effectively means outlets every 12 feet along unbroken walls. Each wall section separated by a door counts independently. Kitchens and bathrooms have additional requirements.
Example Calculation
40 ft of total wall length with 2 doorways, 12 ft max spacing.
- 01Base outlets = ceil(40 / 12) = 4
- 02Add 1 per doorway = 4 + 2 = 6 outlets
- 03Actual spacing = 40 / 6 = 6.7 ft apart
