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.
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.
