■ Ungrounded conductors must be simultaneously disconnected when two or

more branch circuits supply devices on the same yoke. Section 210.7 is intended to reduce the likelihood of unexpected shock hazards for persons working on devices on the same yoke that are connected to multiple branch circuits. A means to simultaneously disconnect the ungrounded conductors must be provided at the point where the branch circuits originate when two or more branch circuits supply devices on the same yoke. Although the title in the 2011 NEC® for Section 210.7 has changed to clearly state this section deals with Multiple Branch Circuits, the requirement remains the same. Section 210.4(B) addresses a similar hazard when a multiwire branch circuit supplies devices on the same yoke. The ungrounded conductors must also be simultaneously disconnected at the point where the branch circuit originates. An informational note was added to Section 404.8(C) as a reminder that Section 210.7 applies if multiple circuits are supplying a multipole switch.

GFCI protection of Receptacles Near Sinks in Dwellings

6' ■ 15A and 20A, 125V receptacles within 6 feet of a sink in a dwelling must

be GFCI protected.

■ GFCIs installed per 210.8 must be readily accessible. Ground Fault Circuit Interrupters that provide protection for receptacles as specified in Sections 210.8 (A), (B) and (C) must now be installed in a readily accessible location. GFCIs are marked “test monthly” and are provided with a test button that must be operated monthly to insure that the GFCI is functioning properly. Locating a GFCI where it is accessible will increase the likelihood that the GFCI will be tested by the user. A location that is Readily Accessible is defined in Article 100 of the NEC®.

GFCI protection must be provided for receptacles within 6 feet of all sinks in a dwelling. Previously, the requirement applied only to laundry, wet bar and utility sinks. This revision to the 2011 NEC® parallels the requirement in Section 210.8(B)(5) to provide GFCI protection for receptacles within 6 feet of sinks in commercial and other non-dwelling installations. The code now insures that the same level of GFCI protection is provided for receptacles near sinks in all installations. Although Section 210.8(A)(7) states that the requirement applies to sinks other than those in kitchens, the intent is not to exempt countertop receptacles near kitchen sinks from having GFCI protection. Kitchen countertop receptacles are to required to have GFCI protection per Section 210.8(A)(6). As a result, receptacles that serve countertops located near kitchen sinks will have GFCI protection. The wording of Section 210.8(A)(7) is intended to make it clear that other receptacles, such as dishwasher and disposal receptacles that may be within 6 feet of a kitchen countertop sink, are not required to have GFCI protection.

SECTION 210.8(B)(6)

GFCI Protection of Receptacles Near Sinks in Health Care Facilities

GFCI Protection of Indoor Wet Location Receptacles

PZ1624

■ GFCI protection is required for 15A and 20A, 125V receptacles within 6 feet of sinks except in patient bed locations in general care or critical care areas. The exception to Section 210.8(B)(5) has been revised to make it clear that GFCI protection is not required for receptacles located near sinks in patient bed locations of general care or critical care areas. There is concern that receptacles located near hand washing sinks in these areas may be used for patient care life support, monitoring, and other portable patient care equipment that should not be plugged into a receptacle protected by a GFCI. Patient Bed Locations, Critical Care Areas and General Care Areas are defined in Article 517 of the code.

■ 15A and 20A, 125V receptacles located in indoor wet locations are

required to be GFCI protected. This new section has been added to the 2011 NEC® to require GFCI protection for receptacles located in indoor wet locations in other than dwellings. An indoor wet location is an area such as a car wash or food processing facility. Receptacles located in indoor wet locations are exposed to the same potentially hazardous conditions that exist in outdoor wet locations. Section 210.8(B)(4) requires outdoor receptacles to be GFCI protected. This new requirement will insure that receptacles in indoor wet locations are provided with the same level of GFCI protection.

This exception does not apply to other locations in Health Care Facilities. The exception is specific to General and Critical Care Areas. A receptacle located within 6 feet of a sink in other areas must be GFCI protected.

associated shower facility must be GFCI protected. GFCI protection is now required for receptacles located in locker rooms that have an associated shower facility. A shower located near a locker room may create a hazardous condition. The damp and wet conditions in a locker room due to proximity to a shower, the use of electrical personal grooming equipment, such as a hair dryer, people with bare feet exposed to the damp tile floor of a locker room, all contribute to the increased risk of electrical shock. GFCI protected receptacles will provide a significantly increased level of safety in this type of environment.

GFCI protection for receptacles in dwelling unit garages is required by Section 210.8(A)(2). Section 511.12 requires GFCI protection for receptacles in commercial service and repair garages where volatile flammable liquids or gases are used for vehicle fuel or power. This new Section, 210.8(B)(8), ensures that the same level of GFCI protection for receptacles will be provided in all garages, service bays and similar areas where electrical diagnostic equipment, electrical hand tools and portable lighting equipment are used. An example of a garage or service area not previously covered is a service facility for plug-in electric hybrid vehicles.

■ A Circuit Breaker or Receptacle Type AFCI must provide protection of ■ A Receptacle Type AFCI may provide protection of the branch circuit. In the 2008 NEC® the definition for an AFCI was in section 210.12(A). The definition has been relocated to Article 100 in the 2011 NEC®. As a result of moving the AFCI definition to article 100, the requirements for AFCI protection that were stated in Section 210.12(B) in the 2008 NEC® have been moved to section 210.12(A). Section 210.12(A) in the 2011 NEC® requires AFCI protection for 120 volt, 15 and 20 amp branch circuits supplying outlets in family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas. The exceptions to 210.12(A) permit a receptacle type Outlet Branch Circuit AFCI to provide the required protection when located at the first outlet of the branch circuit under the following conditions: Exception No. 1 – The branch circuit conductors from the origin of the branch circuit to the first outlet are installed in RMC, IMC, EMT, MC cable or steel armored AC cable. Metal outlet and junction boxes must also be used between the origin of the branch circuit and the first outlet. Exception No. 2 – The branch circuit conductors from the branch circuit overcurrent device to the first outlet are installed in listed metal or nonmetallic conduit or tubing encased in at least 2 inches of concrete.

Section 210.12(A) in the 2011 NEC® requires AFCI protection for 120 volt, 15 and 20 amp branch circuits supplying outlets in family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas. A new section, 210.12(B), has been added to require AFCI protection for branch circuit modifications and extensions of the circuits specified in Section 210.12(A). The AFCI protection for the modified or extended circuits may be a listed Combination AFCI at the origin of the branch circuit or a listed Outlet Branch Circuit AFCI located at the first receptacle outlet of the circuit. The Combination AFCI located at the origin of the branch circuit is typically a circuit breaker AFCI. The Outlet Branch Circuit AFCI located at the first receptacle outlet will be a receptacle type AFCI. Either device may be used to meet the requirements of 210.12(B).

general provisions for receptacle spacing.

Section 210.52(A) provides the spacing requirements for the installation of receptacles in dwellings. When measured horizontally along the floor line of a wall space no point may be more than 6 feet from a receptacle. Section 210.52(A)(2)(1) defines a wall space as any space that is at least 2 feet wide and is uninterrupted along the floor line by an opening. In addition to openings, this section has been revised to include fixed cabinets. This insures that fixed cabinets, such as kitchen cabinets, are taken into account and are not included when determining the unbroken width of a wall space.

Section 406.4(E) prohibits the installation of receptacles in a face up position in countertops. However, sections 210.52(C)(5) and 210.52(D) have been revised to permit listed receptacle outlet assemblies to be installed in kitchen and bathroom countertops. This change has been made to allow the installation of receptacle assemblies in the top surface of a countertop. The receptacle assemblies must be listed to insure that they have been evaluated to function properly when exposed to conditions likely to be encountered in countertop installations, such as liquid spills and splashing. A typical receptacle assembly for this application is a pop up type of receptacle having a cover that is flush with the countertop when not in use and pops up when operated to reveal the receptacle face.

Receptacles on Balconies, Decks and Porches

Receptacles in Basements, Garages and Accessory Buildings

The receptacle must be located within the perimeter of the balcony, deck or porch.

At least one 125 volt, 15 or 20 amp outdoor receptacle must be provided to serve a balcony, deck or porch of a dwelling. The receptacle must be located within the perimeter of the balcony, deck or porch. This requirement is intended to avoid the use of extension cords routed from an inside receptacle through windows or doorways to supply holiday lighting and other electrically operated products used outdoors. The 2008 NEC® had an exception stating that for areas less than 20 ft2 a receptacle was not required. The 2011 NEC® has deleted this exception recognizing that electrically operated products could be used on decks, porches and balconies having an area less than specified in the exception.

■ At least one receptacle outlet is required in each basement, garage and

accessory building in one family dwellings. Accessory buildings have been added as a location where at least one receptacle must be installed. Many dwellings have additional buildings, other than garages, where electrical equipment is utilized. Section 210.8(A)(2) requires the receptacle to be GFCI protected.

circuit overcurrent protection.

Receptacle outlets will now be required in foyers. This change recognizes that many homes are built with large foyers. Lamps and other cord and plug connected electrical equipment will be located in these foyers and receptacles are required for connection of this equipment. A foyer having an area of greater than 60 ft² must have a receptacle located in each continuous wall that has a width of at least 3 ft that is unbroken by a floor to ceiling window, a door or other similar opening.

Type 3 Surge Protective Devices (SPD) installed on the load side of the branch circuit overcurrent protection were required by Section 285.25 of the 2008 NEC® to be located at least 30 feet from the service. In the 2011 NEC® this section has been revised to state that the requirement to install the Type 3 SPD at least 30 feet from the service is necessary only when specified in the manufacturers instructions. This change recognizes that a Type 3 SPD that has been subjected to additional testing may be installed anywhere in the branch circuit on the load side of the overcurrent protection. UL 1449, the Standard for Surge Protective Devices, requires a Type 3 SPD that has not been evaluated by the additional testing to be marked “CAUTION – Do not install this device if there is not at least 10 meters (30 feet) or more of wire between the electrical outlet and the electrical service panel.” If this marking does not appear on the SPD or in the instruction sheet the Type 3 SPD may be installed anywhere in the branch circuit. Type 3 SPDs are typically cord connected power strips or receptacle type devices.

When a ceiling box is installed in a location where a ceiling-suspended fan may be installed and when a spare, separately switched, ungrounded conductor is provided, the box must be listed for support of a fan. Section 314.27(C) has been revised to recognize that when a ceiling box is installed under these conditions it is likely that a ceilingsuspended fan will be installed on the box. This requirement applies only to single and multi-family dwellings.

A wall box intended to support a luminaire must be marked to indicate the maximum weight of the luminaire to be supported, if other than 50 pounds. An exception allows wall type luminaires weighing 6 pounds or less to be supported by device boxes, plaster rings or other boxes when the luminaire is secured by at least two No. 6 or larger screws.

Multioutlet Assemblies

Underfloor Raceways

■ Field assembled Multioutlet Assemblies must comply with wire bending

space and pull box requirements. Article 380 provides the installation requirements for Multioutlet Assemblies. A new Section, 380.23, specifies the wire bending space and pull requirements for conductors in field assembled multioutlet assemblies. Section 380.23 does not apply to listed, factory assembled multioutlet assemblies. Section 380.23(A) requires insulated conductors installed in a field assembled multioutlet assembly to comply with the wire bending space specifications in Table 312.6(A). Where a multioutlet assembly is used as a pull box for 4 AWG or larger insulated conductors, Section 380.23(B) requires compliance with Section 314.28(A)(1) for straight pulls and Section 314.28(A)(2) for angle pulls.

■ A new definition for Underfloor Raceway has been added to the code. Although the requirements in Article 390 for Underfloor Raceways remain the same, Section 390.2 now provides a definition. Underfloor Raceways are installed flush or beneath the floor surface and are intended for the installation of conductors. The underfloor raceway may be equipped with junction boxes for access to the conductors as well as a wide variety of fittings such as floor boxes and pedestals that allow power, voice and data connectivity.

Section 380.23 applies only to field assembled multioutlet assemblies. There was concern that conductors could be damaged when installed in field assembled multioutlet assemblies. Another change to this Article is that Section 380.1 has been revised to add an informational note that directs the user to the definition of a Multioutlet Assembly in Article 100.

equipment grounding conductor.

This is a new section that requires the grounded circuit conductor of the lighting circuit to be provided at the switch location. Many lighting control devices, such as an occupancy sensor, require low levels of stand-by current for proper operation. In many installations, the equipment grounding conductor is the only available conductor that can be used as a circuit conductor for this low level stand-by current. The intent of this change in the code is to be certain that the lighting circuit grounded conductor is available for the proper operation of the lighting control device. This ensures that operation of the control device does not rely on connection to the equipment grounding conductor. The result is that there will be no undesirable current on the equipment grounding conductor. The use of electronic lighting control devices is expected to increase due to increased emphasis on energy efficient lighting systems.

This section requires snap switches, dimmers and similar control switches to be connected to the equipment grounding conductor by the means specified in Section 404.9(B)(1) and (2). This rule ensures that a metal faceplate installed on the switch will be grounded. There are three exceptions to this requirement:

This section has been revised to require an “Extra Duty” While-In-Use cover in installations where the box is supported from grade in other than one and two family dwellings. The intent of this revision in the code is to ensure that covers mounted on boxes supported by conduit, stanchions, wood braces or other free standing rigid supports can withstand the severe service conditions expected in these installations. The “Extra Duty” covers are evaluated to more demanding test requirements than general purpose covers. The covers must be listed and marked “Extra Duty.”
