Section 210.52/Dwelling Unit Receptacle Outlets

NEC 210.52 specifies minimum receptacle outlet locations in dwelling units, including the 6-foot wall spacing rule and kitchen countertop requirements.

What this section requires

In every habitable room, receptacle outlets must be installed so that no point along the floor line of any wall space is more than 6 feet from a receptacle outlet. Any wall space 2 feet or wider requires a receptacle. Kitchen countertop spaces 12 inches or wider must have a receptacle, and no point along the countertop wall line can be more than 24 inches from an outlet. At least one outdoor receptacle must be accessible from grade at the front and back of the dwelling.

Why this section exists

The 6-foot rule ensures that any appliance with a standard 6-foot cord can reach a receptacle from any point in the room without an extension cord. Extension cord overuse is a significant fire hazard. The countertop requirements address the high density of portable appliance use in kitchens where cords draped across sinks and cooktops create additional hazards.

What plan reviewers look for

Plan reviewers measure wall segments on the floor plan and verify that receptacles are placed within the required spacing. They check kitchen countertop receptacle placement against the 24-inch rule. They also verify dedicated outdoor, garage, basement, and hallway receptacle locations. Wall space behind doors, around fireplaces, and at fixed glass panels all count and are commonly overlooked.

Common violations

Wall space exceeds 12 feet between receptacles
A long wall in a bedroom or living room has receptacles spaced more than 12 feet apart. The 6-foot rule means no point can be more than 6 feet from an outlet, so the maximum spacing between receptacles is 12 feet.
Kitchen countertop gap exceeds 48 inches
A countertop run has receptacles spaced so that a point along the wall line exceeds 24 inches from an outlet. Between two outlets, the maximum gap is 48 inches.
Missing outdoor receptacle
No receptacle is shown at the front or rear of the dwelling accessible from grade level. Both locations require at least one receptacle.
Compliance tip
Lay out receptacles on the floor plan and dimension the spacing. Show countertop receptacles on the kitchen enlarged plan with dimensions to verify the 24-inch rule. Do not forget outdoor, garage, basement, and hallway receptacles.
