In every kitchen, family room, dining room, living room, parlor, library, den, sun room, bedroom, recreation room, screened porch or breezeway or similar room or area of dwelling units, receptacle outlets shall be installed so that no point along the floor line in any wall space is more than six feet (1.83 m), measured horizontally, from an outlet in that space, including any wall space two feet (610 mm) or more in width and the wall space occupied by fixed panels in exterior walls, but excluding sliding panels in exterior walls. The wall space afforded by fixed room dividers, such as freestanding bar-type counters, shall be included in the six foot (1.83 m) measurement.
As used in this section a “wall space” shall be considered a wall unbroken along the floor line by doorways, fireplaces and similar openings. Each wall space two or more feet (610 mm or more) wide shall be treated individually and separately from other wall spaces within the room. A wall space shall be permitted to include two or more walls of a room (around corners) where unbroken at the floor line.
(FPN): The purpose of this requirement is to minimize the use of cords across doorways, fireplaces and similar openings.
Receptacle outlets shall, insofar as practicable, be spaced equal distances apart. Receptacle outlets in floors shall not be counted as part of the required number of receptacle outlets unless located close to the wall.
The receptacle outlets required by this section shall be in addition to any receptacle that is part of any lighting fixture or appliance, located within cabinets or cupboards, or located over five and one-half feet (1.68 m) above the floor.
Exception: Permanently installed electric baseboard heaters equipped with factory-installed receptacle outlets or outlets provided as separate assembly by the manufacturer shall be permitted as the required outlet or outlets for the wall space utilized by such permanently installed heaters. Such receptacle outlets shall not be connected to the heater circuits.
(FPN): Listed baseboard heaters include instructions which may-not permit their installation below receptacle outlets.
