as close as practicable to the countertop area to be served. The total number of receptacle outlets serving the countertop shall not be less than the number needed to satisfy 210.52(C)(1). These outlets shall be located in accordance with 210.52(C)(3). Figure 210.52(C)(1) Determination of Area Behin...

as close as practicable to the countertop area to be served. The total number of receptacle outlets serving the countertop shall not be less than the number needed to satisfy 210.52(C)(1). These outlets shall be located in accordance with 210.52(C)(3). Figure 210.52(C)(1) Determination of Area Behind a Range, Counter-Mounted Cooking Unit, or Sink. ENHANCED CONTENT Collapse The following exhibit illustrates dwelling unit receptacles serving countertop spaces in a kitchen and arranged in accordance with 210.52(C)(1) through (C)(3). Dwelling unit receptacles that serve countertop spaces in kitchens, dining areas, and similar rooms are required to be installed as follows: 1. In each wall space wider than 12 inches and spaced so that no point along the wall line is more than 24 inches from a receptacle 2. For countertop islands and peninsular countertops, according to 210.52(C)(2) and 210.52(C)(3) 3. Accessible for use and not blocked by appliances occupying dedicated space or fastened in place 4. Supplied by the two (more are permitted) required 20-ampere small- appliance branch circuits and GFCI protected according to 210.8(A)(6) 5. Not more than 20 inches above the countertop (According to 406.5, receptacles cannot be installed in a face-up position, unless in specifically listed countertop or work surface applications. Receptacles installed in a face-up position in a countertop could collect crumbs, liquids, and other debris, resulting in a potential fire or shock hazard.) Exception No. 1. This exception and Figure 210.52(C)(1) define the wall space behind a sink, range, or counter-mounted cooking unit that is not required to be provided with a receptacle outlet. Figure 210.52(C)(1) shows the wall space behind the sink or range that is exempt from the wall line measurement. Where the space behind a sink, range, or counter-mounted cooking unit is 12 inches or more (or 18 inches for corner-mounted configurations), the space must be included in measuring the wall counter space. Receptacle outlets are not prohibited from being installed in this space. (2) Island and Peninsular Countertops and Work Surfaces. Receptacle outlets, if installed to serve an island or peninsular countertop or work surface, shall be installed in accordance with 210.52(C)(3). If a receptacle outlet is not provided to serve an island or peninsular countertop or work surface, provisions shall be provided at the island or peninsula for future addition of a receptacle outlet to serve the island or peninsular countertop or work surface. (3) Receptacle Outlet Location. Receptacle outlets shall be located in one or more of the following: * (1) On or above, but not more than 500 mm (20 in.) above, a countertop or work surface * (2) In a countertop using receptacle outlet assemblies listed for use in countertops * (3) In a work surface using receptacle outlet assemblies listed for use in work surfaces or listed for use in countertops Receptacle outlets rendered not readily accessible by appliances fastened in place, appliance garages, sinks, or rangetops as covered in 210.52(C)(1), Exception No. 1, or appliances occupying assigned spaces shall not be considered as these required outlets. Informational Note No. 1: See 406.5(E) for installation of receptacles in countertops and 406.5(F) for installation of receptacles in work surfaces. See 380.10 for installation of multioutlet assemblies. Informational Note No. 2: See Informative Annex J and ANSI/ICC A117.1-2009, Standard on Accessible and Usable Buildings and Facilities, for additional information. ENHANCED CONTENT Collapse If a receptacle is installed to serve an island or peninsular countertop, it must be GFCI protected and installed based on Option 1 or Option 2 as depicted in in the exhibit below. Option 1 permits the receptacle to be installed above the countertop within an elevated backsplash space, but not more than 20 inches above the countertop. Option 2 allows the receptacle to be installed within the countertop surface within a listed assembly as specified in 210.52(C)(3)(1) and (2). If Option 1 or Option 2 is not selected at the time of installation, the NEC requires a default to Option 3, which requires a provision to be added at the island so a receptacle could be installed in the future. One means of accomplishing Option 3 could be installing a junction box, with the appropriate NEC-required small-appliance branch circuit, located within the island or peninsular cabinet space. Bathrooms. At least one receptacle outlet shall be instal?led in bathrooms within 900 mm (3 ft) of the outside edge of each sink. The receptacle outlet shall be located on a wall or partition that is adjacent to the sink or sink countertop, located on the countertop, or installed on the side or face of the sink cabinet. In no case shall the receptacle be located more than 300 mm (12 in.) below the top of the sink or sink countertop. Receptacle outlet assemblies listed for use in countertops shall be permitted to be installed in the countertop. Informational Note: See 406.5(E) and 406.5(G) for requirements on installation of receptacles in countertops. ENHANCED CONTENT Collapse The permission to install a receptacle outlet on the basin cabinet is not contingent on the adjacent wall location being infeasible. This receptacle is also required to be GFCI protected in accordance with 210.8(A)(1). This receptacle is required in addition to any receptacle that is part of any luminaire or medicine cabinet. If there is more than one basin, a receptacle outlet is required adjacent to each basin location. One receptacle outlet within 36 inches off both basins can be used to satisfy this requirement. Section 210.11(C)(3) requires that receptacle outlets be supplied from a 20- ampere branch circuit with no other outlets. However, this circuit is permitted to supply the required receptacles in more than one bathroom. If the circuit supplies the required receptacle outlet in only one bathroom, it is also allowed to supply lighting and an exhaust fan in that bathroom, provided the lighting and fan load does not exceed that permitted by 210.23(B)(2). Receptacle outlets installed in addition to the one(s) required by 210.52(D) to serve countertop or other work surfaces are also permitted to be supplied by the required 20-ampere branch circuit. See also 406.9(C), which prohibits installation of a receptacle over a bathtub or inside a shower stall. See also the enhanced content to 210.8(A)(1) for a sample electrical layout of GFCI-protected receptacles in a bathroom. Outdoor Outlets. Outdoor receptacle outlets shall be installed in accordance with 210.52(E)(1) through (E)(3). ENHANCED CONTENT Collapse Outdoor receptacles must be installed so that the receptacle faceplate rests securely on the supporting surface to prevent moisture from entering the enclosure. On uneven surfaces such as brick, stone, or stucco, it might be necessary to use mounting blocks or to close openings with caulking compound or mastic. See also 406.9 for more information on receptacles installed in damp or wet locations. One-Family and Two-Family Dwellings. For a one-family dwelling and each unit of a two-family dwelling that is at grade level, at least one receptacle outlet readily accessible from grade and not more than 2.0 m (61/2 ft) above grade level shall be installed at the front and back of the dwelling. ENHANCED CONTENT Collapse Two outdoor receptacle outlets are required for each dwelling unit. One receptacle outlet is required at the front and one at the back, as shown in the following exhibit. The two required receptacle outlets are to be available to a person standing on the ground (at grade level). Where outdoor heating, air-conditioning, and refrigeration equipment is located at grade level, the receptacle outlets required by this section can be used to comply with the requirement of 210.63, provided that one of the outlets is located within 25 feet of the equipment. Outdoor receptacle outlets on decks, porches, and similar structures can be used to meet 210.52(E) as long as the receptacle outlet is not more than 61/2 feet above grade and can be accessed by a person standing at grade. (2) Multifamily Dwellings. For each dwelling unit of a multifamily dwelling where the dwelling unit is located at grade level and provided with individual exterior entrance/egress, at least one receptacle outlet readily accessible from grade and not more than 2.0 m (61/2 ft) above grade level shall be installed. ENHANCED CONTENT Collapse This requirement applies to the dwelling units that are located at grade level and have a doorway that leads directly to the exterior of the structure. The unauthorized use of the outdoor receptacle outlet by other than the dwelling occupant(s) can be allayed by a switch inside the dwelling unit that controls the receptacle. Due to the spatial constraints often associated with the construction of multifamily units, the required receptacle outlet is permitted to be accessible “from grade” rather than “while standing at grade,” as is the case for one- and two-family dwellings. An outdoor receptacle outlet located 61/2 feet or less above grade and accessible by walking up a set of deck or porch steps can be used to meet this requirement. (3) Balconies, Decks, and Porches. Balconies, decks, and porches that are within 102 mm (4 in.) horizontally of the dwelling unit shall have at least one receptacle outlet accessible from the balcony, deck, or porch. The receptacle outlet shall not be located more than 2.0 m (61/2 ft) above the balcony, deck, or porch walking surface. ENHANCED CONTENT Collapse Regardless of area, a porch, balcony, or deck must have at least one receptacle outlet installed within its perimeter. This requirement applies only to porches, balconies, or decks that are attached to or within 4 inches horizontally from the unit. The porch, balcony, or deck does not need to be accessible from inside the unit for the requirement to apply. Because it is an outdoor receptacle, GFCI protection is required. Depending on the location of the porch, balcony, or deck, the receptacle outlet can also be used to meet the receptacle requirements of 210.52(E)(1) and (E)(2). The receptacle must be not more than 61/2 feet above the balcony, deck, or porch walking surface. (F) Laundry Areas. In dwelling units, at least one receptacle outlet shall be installed in areas designated for the installation of laundry equipment. Exception No. 1: A receptacle for laundry equipment shall not be required in a dwelling unit of a multifamily building where laundry facilities are provided on the premises for use by all building occupants. Exception No. 2: A receptacle for laundry equipment shall not be required in other than one- family dwellings where laundry facilities are not to be installed or permitted. ENHANCED CONTENT Collapse A laundry receptacle outlet(s) is supplied by a 20-ampere branch circuit that can have no other outlets. For more information on laundry branch circuits, see 210.11(C)(2). (G) Basements, Garages, and Accessory Buildings. For one- and two-family dwellings, and multifamily dwellings, at least one receptacle outlet shall be installed in the areas specified in 210.52(G)(1) through (G)(3). These receptacles shall be in addition to receptacles required for specific equipment. Receptacles supplying only a permanently installed premises security system shall not be considered as meeting these requirements. (1) Garages. In each attached garage and in each detached garage with electric power, at least one receptacle outlet shall be installed in each vehicle bay and not more than 1.7 m (51/2 ft) above the floor. Exception: Garage spaces not attached to an individual dwelling unit of a multifamily dwelling shall not require a receptacle outlet in each vehicle bay. (2) Accessory Buildings. In each accessory building with electric power. (3) Basements. In each separate unfinished portion of a basement. ENHANCED CONTENT Collapse Receptacle outlets are not required for a detached garage if it is not supplied with electricity. Receptacle outlets are not required for individual garages of multifamily dwellings where the garage is not attached to the dwelling unit. An example of how this applies is a multifamily dwelling with a separate detached garage structure. Each of the dwelling units is provided with a garage space but the space is not attached to the dwelling unit, therefore a receptacle outlet is not required in each of the detached garage spaces. GFCI protection is required by 210.8(A)(5) for receptacles in finished and unfinished basements and by 210.8(A)(2) for receptacles installed in garages. Circuits that supply receptacle outlets in a garage can supply receptacle outlets only in the garage and readily accessible outdoor receptacle outlets. For more information on garage branch circuits, see 210.11(C)(4). (H) Hallways. In dwelling units, hallways of 3.0 m (10 ft) or more in length shall have at least one receptacle outlet. As used in this subsection, the hallway length shall be considered the length along the centerline of the hallway without passing through a doorway. ENHANCED CONTENT Collapse This requirement is intended to minimize strain or damage to cords and receptacles for dwelling unit receptacles. The requirement does not apply to common hallways of hotels, motels, apartment buildings, condominiums, and similar occupancies. (I) Foyers. Foyers that are not part of a hallway in accordance with 210.52(H) and that have an area that is greater than 5.6 m2 (60 ft2) shall have a receptacle(s) located in each wall space 900 mm (3 ft) or more in width. Doorways, door- side windows that extend to the floor, and similar openings shall not be considered wall space. ENHANCED CONTENT Collapse Foyers are not included in the living spaces covered by 210.52(A) even though they may have comparable dimensions in some cases. This requirement provides for receptacle outlets in these spaces to accommodate lamps or other utilization equipment. The primary objective of the requirements covering any of the dwelling areas included in 210.52 is to minimize the need to use extension cords to supply utilization equipment. 210.60 Guest Rooms, Guest Suites, Dormitory Units, and Similar Occupancies. (A) General. Guest rooms or guest suites in hotels or motels, sleeping rooms in dormitory units, and similar occupancies shall have receptacle outlets installed in accordance with 210.52(A) and (D). Guest rooms or guest suites provided with permanent provisions for cooking shall have receptacle outlets installed in accordance with all of the applicable rules in 210.52. (B) Receptacle Placement. The total number of receptacle outlets shall not be less than required in 210.52(A). These receptacle outlets shall be permitted to be located conveniently for permanent furniture layout. At least two receptacle outlets shall be readily accessible. Where receptacles are installed behind the bed, the receptacle shall be located to prevent the bed from contacting any attachment plug that may be installed or the receptacle shall be provided with a suitable guard. ENHANCED CONTENT Collapse The receptacles in guest rooms and guest suites of hotels and motels and in dormitories are permitted to be placed in accessible locations that are compatible with permanent furniture. However, the minimum number of receptacles required by 210.52 is not permitted to be reduced and should be determined by assuming furniture is not in the room. The practical locations of that minimum number of receptacles are then determined based on the permanent furniture layout. Hotel and motel rooms and suites are commonly used as remote offices for businesspeople who use laptop computers and other plug-in devices. In dormitories, the use of electrical and electronic equipment can be significant, necessitating accessible receptacle outlets. The NEC requires that two receptacle outlets be readily accessible without requiring the movement of furniture to access those receptacles. To reduce the risk of bedding material fires, receptacles located behind beds must include guards if attachment plugs could contact the bed to protect against cords being pinched and damaged by bedframes, mattresses, or box springs. Extended-stay hotels and motels are often equipped with permanent cooking equipment and countertop areas. All applicable receptacle spacing and supply requirements in 210.52 apply to guest rooms or suites that contain such provisions. A portable microwave oven is not considered to be a permanently installed cooking appliance. The following exhibit shows a hotel guest room in which the receptacles are located based on the permanent furniture layout. Because of this rule, some spaces that are 2 feet or more in width have no receptacle outlets. However, the receptacle locations are compatible with the permanent furniture layout. The receptacle outlet adjacent to the permanent dresser is needed because 210.60(B) applies only to the location of receptacle outlets, not to the minimum number of receptacle outlets. See also 210.17 for more information on hotel and motel guest rooms and guest suites that are equipped with permanent provisions for cooking. 210.62 Show Windows. At least one 125-volt, single-phase, 15- or 20-ampere-rated receptacle outlet shall be installed within 450 mm (18 in.) of the top of each show window. No point along the top of the window shall be farther than 1.8 m (6 ft) from a receptacle outlet. ENHANCED CONTENT Collapse Some show windows extend from floor to ceiling for maximum display. To discourage floor receptacles and the use of extension cords, receptacles must be installed directly above the show window, within 18 inches of the top, and no point along the top of the window is permitted to be more than 6 feet from a receptacle. This requirement requires the use of 125-volt, 15- or 20- ampere receptacles. Such a receptacle would still be required if a circuit were provided for a 24-volt lighting system. For information on load calculations for show windows, see 220.14(G) and 220.46(A). 210.63 Equipment Requiring Servicing. A 125-volt, single-phase, 15- or 20-ampere-rated receptacle outlet shall be instal?led at an accessible location within 7.5 m (25 ft) of the equipment as specified in 210.63(A) and (B). Informational Note: See 210.8(E) for requirements on GFCI protection. (A) Heating, Air-Conditioning, and Refrigeration Equipment. The required receptacle outlet shall be located on the same level as the heating, air-conditioning, and refrigeration equipment. The receptacle outlet shall not be connected to the load side of the equipment’s branch-circuit disconnecting means. Exception: A receptacle outlet shall not be required at one- and two-family dwellings for the service of evaporative coolers. ENHANCED CONTENT Collapse Requiring a permanently installed receptacle within 25 feet of equipment that requires servicing improves worker safety by eliminating the need to employ makeshift methods of obtaining 120-volt power for servicing and troubleshooting. The exception exempts evaporative coolers (commonly referred to as swamp coolers) from the receptacle requirement where the cooler is installed at a one- or two-family dwelling. Although this type of cooling equipment is exempt from 210.63, one- and two-family dwellings are required to have outdoor receptacle outlets at the front and the back of the structure in accordance with 210.52(E). (B) Other Electrical Equipment. In other than one- and two-family dwellings, a receptacle outlet shall be located as specified in 210.63(B)(1) and (B)(2). (1) Indoor Service Equipment. The required receptacle outlet shall be located within the same room or area as the service equipment. (2) Indoor Equipment Requiring Dedicated Equipment Spaces. Where equipment, other than service equipment, requires dedicated equipment space as specified in 110.26(E), the required receptacle outlet shall be located within the same room or area as the electrical equipment and shall not be connected to the load side of the equipment’s disconnecting means. ENHANCED CONTENT Collapse The required receptacle is intended to facilitate the use of portable test and diagnostic equipment that requires a 120-volt power source. The receptacle is not permitted to be on the load side of the equipment’s branch-circuit disconnecting means so that the receptacle can be used while the disconnecting means is open. The receptacle is not required in one- or two- family dwellings. 210.65 Meeting Rooms. (A) General. Each meeting room of not more than 93 m2 (1000 ft2) in other than dwelling units shall have outlets for nonlocking-type, 125-volt, 15- or 20-ampere receptacles. The outlets shall be installed in accordance with 210.65(B). Where a room or space is provided with movable partition(s), each room size shall be determined with the partition in the position that results in the smallest size meeting room. Informational Note No. 1: For the purposes of this section, meeting rooms are typically designed or intended for the gathering of seated occupants for such purposes as conferences, deliberations, or similar purposes, where portable electronic equipment such as computers, projectors, or similar equipment is likely to be used. Informational Note No. 2: Examples of rooms that are not meeting rooms include auditoriums, schoolrooms, and coffee shops. (B) Receptacle Outlets Required. The total number of receptacle outlets, including floor outlets and receptacle outlets in fixed furniture, shall not be less than as determined in 210.65(B)(1) and (B)(2). (1) Receptacle Outlets in Fixed Walls. The required number of receptacle outlets shall be determined in accordance with 210.52(A)(1) through (A)(4). These receptacle outlets shall be permitted to be located as determined by the installer, designer, or building owner. (2) Floor Outlets. A meeting room with any floor dimension that is 3.7 m (12 ft) or greater in any direction and that has a floor area of at least 20 m2 (215 ft2) shall have at least one floor receptacle outlet, or at least one floor outlet to serve a receptacle(s), located at a distance not less than 1.8 m (6 ft) from any fixed wall for each 20 m2 (215 ft2) or fraction thereof. Informational Note No. 1: See 314.27(B) for requirements on floor boxes used for receptacles located in the floor. Informational Note No. 2: See 518.1for requirements on assembly occupancies designed for 100 or more persons. ENHANCED CONTENT Collapse These requirements apply to meeting rooms in a variety of occupancies, including office buildings and hotels. For most rooms in commercial buildings, there are no NEC requirements for spacing of wall and countertop receptacles. However, 210.65 recognizes that there is a need to provide receptacles to facilitate meetings in which attendees will be using computers. Means of compliance include floor receptacle outlets and floor outlets supplying hard-wired furniture that contains receptacles. The 6-foot distance from fixed walls is to allow for emergency egress without occupants having to cross over flexible cords. 210.70 Lighting Outlets Required. Lighting outlets shall be installed where specified in 210.70(A), (B), and (C). The switch or wall-mounted control device shall not rely exclusively on a battery unless a means is provided for automatically energizing the lighting outlets upon battery failure. (A) Dwelling Units. In dwelling units, lighting outlets shall be installed in accordance with 210.70(A)(1) and (A)(2). (1) Habitable Rooms, Kitchens, Laundry Areas, and Bathrooms. At least one lighting outlet controlled by a listed wall-mounted control device shall be installed in every habitable room, kitchen, laundry area, and bathroom. The wall-mounted control device shall be located near an entrance to the room on a wall. Exception No. 1: In other than kitchens, laundry areas, and bathrooms, one or more receptacles controlled by a listed wall-mounted control device shall be permitted in lieu of lighting outlets. Exception No. 2: Lighting outlets shall be permitted to be controlled by occupancy sensors that are (1) in addition to listed wal
