WALL RECEPTACLE OUTLETS
210.52(A)(1) THRU (A)(4)

Section 210.52(A) lists the requirements for installing receptacle outlets in dwelling units, including single-family dwellings, duplexes, single-family dwellings in apartment complexes, townhouses, and condominiums. Per Article 100, a dwelling unit is defined as a single unit, providing complete and independent living facilities for one or more persons, including permanent provisions for:

• Living
• Sleeping
• Sanitation
• Cooking

See Figure 10-6 for a detailed illustration of a dwelling unit.

Receptacles that are an integral part of a luminaire, appliance, or cabinet shall not be counted as one of the required receptacle outlets. Those outlets installed more than 5 ft 6 in. (1.7 m) above the finished floor are not permitted to be counted per 210.52(4). In other words, they shall not be counted as one of the required outlets for normal use. In these cases, additional outlets shall be installed to comply with the number of outlets required per 210.52(A)(1). (See Figure 10-7)

Section 210.52 gives permission for a receptacle to be installed in a listed factory-assembled baseboard heater, so as to prevent extension cords from being plugged into the receptacle outlet above the baseboard heater. Heat from the electric heater elements may overheat the insulation of the cord and cause a fire hazard from the arcing and sparking that can occur. The IN recommends that baseboard heaters be installed according to the instructions accompanying the heater unit per 90.7 and 110.3(B).

Design Tip: This rule applies strictly to electric baseboard heater with heating elements. (See Figure 10-8)

Receptacle outlets shall be installed on walls in every inhabitable room, including the hallway, of every dwelling unit, except the bathroom. The procedure for properly spacing the receptacles along the floor line of an unbroken wall is to provide an outlet within 6 ft (1.8 m) of the cord-and-plug connected equipment per 210.52(A)(1).

The first outlet shall be installed 6 ft (1.8 m) from the door entering the room. The measurement for installing this outlet shall be permitted to be made on either side of the door. From the outlet measured at 6 ft (1.8 m), additional outlets measured at 12 ft (3.7 m) intervals along the unbroken wall shall be installed. Outlets installed in this manner allow electrical appliances with 6 ft (1.8 m) cords to be cord-and-plug connected without the use of an extension cord. Installing the first outlet at 6 ft (1.8 m) and each additional outlet every 12 ft (3.7 m) thereafter complies with this requirement and makes it possible to cord-and-plug connect appliances without creating a fire hazard. Any wall space of 2 ft (600 mm) or more requires an outlet for a receptacle to be installed.

Design Tip: The wall space of 2 ft (600 mm) is based on trimmed-out walls, etc. and not from a 2 ft (600 mm) rough-in measurement of framing members.

A wall space is a wall unbroken along the floor line by a door or similar opening, bookcase, fireplace, fixed cabinets, or window that extends all the way to the floor line. A floor receptacle outlet located close to the wall shall be permitted to be counted as one of the outlets required by 210.52(A)(3). (See Figure 10-9)

Railings used for room dividers, where furniture with floor or table lamps is backed up to the railing, shall have receptacle outlets installed for cord-and-plug connections such as table or floor lamps. This rule is to prevent the use of extension cords, which are usually run through walls, doors, under carpets, etc. per 400.12(1) through (7). [See Figure 10-10(a)]

The sliding portion of an exterior door shall not be considered wall space. Fixed panels, including the fixed portion of a sliding glass door unit in an exterior wall, shall be considered wall space for the purpose of spacing the required number of receptacle outlets per 210.52(A)(2)(2). The NEC permits a floor receptacle to be used to provide the required number of receptacle outlets per 210.52(A)(3). [See Figure 10-10(b)]​​​​​​​

Receptacles installed for countertop surfaces shall not be considered as the receptacles required per 210.52(A).
