Outlets Needed vs Total Wall Length
Formule
## 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.
Exemple Résolu
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
Questions Fréquentes
What is the 6/12 rule?
No point along a wall can be more than 6 feet from an outlet. Since two outlets can serve a 12-foot span (6 ft to the left, 6 ft to the right), the practical spacing is every 12 feet.
Do kitchen outlets follow the same rule?
No. Kitchen countertop outlets must be spaced every 4 feet (NEC 210.52C) and each must be on a 20A small-appliance branch circuit.
