SECTION 210.7

� Ungrounded conductors must be simultaneously disconnected when two ormore branch circuits supply devices on the same yoke.

Disconnection of Multiple Branch Circuits andMultiwire Branch Circuits

Section 210.7 is intended to reduce the likelihood of unexpected shockhazards for persons working on devices on the same yoke that areconnected to multiple branch circuits.

A means to simultaneously disconnect the ungrounded conductors must beprovided at the point where the branch circuits originate when two or morebranch circuits supply devices on the same yoke. Although the title in the2011 NEC® for Section 210.7 has changed to clearly state this section dealswith Multiple Branch Circuits, the requirement remains the same.

Section 210.4(B) addresses a similar hazard when a multiwire branch circuitsupplies devices on the same yoke. The ungrounded conductors must alsobe simultaneously disconnected at the point where the branch circuitoriginates.

An informational note was added to Section 404.8(C) as a reminder thatSection 210.7 applies if multiple circuits are supplying a multipole switch.

Ground Fault Circuit Interrupters that provide protection forreceptacles as specified in Sections 210.8 (A), (B) and (C) must nowbe installed in a readily accessible location. GFCIs are marked “testmonthly” and are provided with a test button that must be operatedmonthly to insure that the GFCI is functioning properly. Locating aGFCI where it is accessible will increase the likelihood that the GFCIwill be tested by the user. A location that is Readily Accessible isdefined in Article 100 of the NEC®.

Readily Accessible GFCIs

SECTION 210.8

� GFCIs installed per 210.8 must be readily accessible.

P&S Cat. #s: 1595, 2095v

GFCI protection must be provided for receptacles within 6 feet of all sinksin a dwelling. Previously, the requirement applied only to laundry, wet barand utility sinks. This revision to the 2011 NEC® parallels the requirementin Section 210.8(B)(5) to provide GFCI protection for receptacles within6 feet of sinks in commercial and other non-dwelling installations. Thecode now insures that the same level of GFCI protection is provided forreceptacles near sinks in all installations.

Although Section 210.8(A)(7) states that the requirement applies to sinksother than those in kitchens, the intent is not to exempt countertopreceptacles near kitchen sinks from having GFCI protection. Kitchencountertop receptacles are to required to have GFCI protection per Section210.8(A)(6). As a result, receptacles that serve countertops located nearkitchen 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 anddisposal receptacles that may be within 6 feet of a kitchen countertop sink,are not required to have GFCI protection.

SECTION 210.8(A)(7)GFCI protection of Receptacles Near Sinks in Dwellings

This new section has been added to the 2011 NEC® to require GFCIprotection for receptacles located in indoor wet locations in other thandwellings. An indoor wet location is an area such as a car wash or foodprocessing facility.

Receptacles located in indoor wet locations are exposed to the samepotentially 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 wetlocations are provided with the same level of GFCI protection.

SECTION 210.8(B)(6)GFCI Protection of Indoor Wet Location Receptacles

� 15A and 20A, 125V receptacles located in indoor wet locations arerequired to be GFCI protected.

The exception to Section 210.8(B)(5) has been revised to make it clearthat GFCI protection is not required for receptacles located near sinksin patient bed locations of general care or critical care areas. There isconcern that receptacles located near hand washing sinks in theseareas may be used for patient care life support, monitoring, and otherportable patient care equipment that should not be plugged into areceptacle protected by a GFCI.

Patient Bed Locations, Critical Care Areas and General Care Areas aredefined in Article 517 of the code.

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

SECTION 210.8(B)(5) Exception No.2 to (5)GFCI Protection of Receptacles Near Sinks in

Health Care Facilities

� GFCI protection is required for 15A and 20A, 125V receptacles within 6feet of sinks except in patient bed locations in general care or criticalcare areas.

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

SECTION 210.8(B)(8)

� 15A and 20A, 125V receptacles in garages where electrical diagnosticequipment, electrical hand tools or portable lighting equipment is usedmust be GFCI protected.

GFCI Protection for Receptacles in Commercial Garages

GFCI protection is now required for receptacles located in lockerrooms that have an associated shower facility. A shower located neara locker room may create a hazardous condition. The damp and wetconditions in a locker room due to proximity to a shower, the use ofelectrical personal grooming equipment, such as a hair dryer, peoplewith bare feet exposed to the damp tile floor of a locker room, allcontribute to the increased risk of electrical shock. GFCI protectedreceptacles will provide a significantly increased level of safety in thistype of environment.

SECTION 210.8(B)(7)GFCI Protection of Receptacles in Locker Rooms

� 15A and 20A, 125V receptacles located in a locker room with anassociated shower facility must be GFCI protected.

In the 2008 NEC® the definition for an AFCI was in section 210.12(A). The definitionhas been relocated to Article 100 in the 2011 NEC®.

As a result of moving the AFCI definition to article 100, the requirements for AFCIprotection that were stated in Section 210.12(B) in the 2008 NEC® have beenmoved to section 210.12(A). Section 210.12(A) in the 2011 NEC® requires AFCIprotection for 120 volt, 15 and 20 amp branch circuits supplying outlets in familyrooms, 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 toprovide the required protection when located at the first outlet of the branchcircuit under the following conditions:

Exception No. 1 – The branch circuit conductors from the origin of the branchcircuit to the first outlet are installed in RMC, IMC, EMT, MC cable or steelarmored AC cable. Metal outlet and junction boxes must also be used between theorigin of the branch circuit and the first outlet.

Exception No. 2 – The branch circuit conductors from the branch circuitovercurrent device to the first outlet are installed in listed metal or nonmetallicconduit or tubing encased in at least 2 inches of concrete.

SECTION 210.12(A) Exception 1&2Arc-Fault Circuit Interrupter (AFCI) Protection of

Outlets in Dwellings

� A Receptacle Type AFCI may provide protection of the branch circuit.

Section 210.12(A) in the 2011 NEC® requires AFCI protection for120 volt, 15 and 20 amp branch circuits supplying outlets in familyrooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms,sunrooms, recreation rooms, closets, hallways, or similar roomsor areas.

A new section, 210.12(B), has been added to require AFCI protectionfor branch circuit modifications and extensions of the circuits specifiedin Section 210.12(A). The AFCI protection for the modified or extendedcircuits may be a listed Combination AFCI at the origin of the branchcircuit or a listed Outlet Branch Circuit AFCI located at the firstreceptacle outlet of the circuit.

The Combination AFCI located at the origin of the branch circuit istypically a circuit breaker AFCI. The Outlet Branch Circuit AFCI locatedat the first receptacle outlet will be a receptacle type AFCI. Eitherdevice may be used to meet the requirements of 210.12(B).

SECTION 210.12(B)Arc-Fault Circuit Interrupter (AFCI) Protection of

Outlets in Dwellings

� A Circuit Breaker or Receptacle Type AFCI must provide protection ofbranch circuit extensions and modifications.

A new section, 210.52(A)(4), has been added to make it clear that thecountertop receptacles installed to comply with Section 210.52(C) maynot be considered as the receptacles that meet the general provisioninstallation requirements for receptacles in Section 210.52(A). Thecountertop receptacles are intended to serve the appliances that areused on a countertop space.

SECTION 210.52(A)(4)Countertop Receptacles

� Receptacles serving countertops are not considered as meeting thegeneral provisions for receptacle spacing.

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

SECTION 210.52(A)(2)(1)Receptacle Spacing in Dwelling Units

� Fixed cabinets are not included in determining the unbroken wallspace for receptacle spacing.

Section 406.4(E) prohibits the installation of receptacles in a face upposition in countertops. However, sections 210.52(C)(5) and 210.52(D)have been revised to permit listed receptacle outlet assemblies to beinstalled in kitchen and bathroom countertops. This change has beenmade to allow the installation of receptacle assemblies in the topsurface of a countertop. The receptacle assemblies must be listed toinsure that they have been evaluated to function properly whenexposed to conditions likely to be encountered in countertopinstallations, such as liquid spills and splashing. A typical receptacleassembly for this application is a pop up type of receptacle having acover that is flush with the countertop when not in use and pops upwhen operated to reveal the receptacle face.

SECTION 210.52(C)(5) and 210.52(D)Receptacles in Kitchen and Bathroom Countertops

� Listed receptacle assemblies may be installed in kitchen and bathroomcountertops.

The conditions describing when a countertop space is divided intoseparate countertop spaces by a counter-mounted cooking unit,range or sink have been moved from the general Section 210.52(C) tosubsection 210.52(C)(4). Although the requirement has not changed, itwas recognized that Section 210.52(C)(4) is the section that deals withseparate countertop spaces.

SECTION 210.52(C)(4)Separate Countertop Spaces

� Receptacles are required in separate countertop spaces.

At least one 125 volt, 15 or 20 amp outdoor receptacle must beprovided to serve a balcony, deck or porch of a dwelling. Thereceptacle must be located within the perimeter of the balcony, deckor porch. This requirement is intended to avoid the use of extensioncords routed from an inside receptacle through windows or doorwaysto supply holiday lighting and other electrically operated products usedoutdoors. The 2008 NEC® had an exception stating that for areas lessthan 20 ft2 a receptacle was not required. The 2011 NEC® has deletedthis exception recognizing that electrically operated products could beused on decks, porches and balconies having an area less thanspecified in the exception.

SECTION 210.52(E)(3)Receptacles on Balconies, Decks and Porches

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

Receptacles in Basements, Garages and Accessory Buildings

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

SECTION 210.52(G)

� At least one receptacle outlet is required in each basement, garage andaccessory building in one family dwellings.

Type 3 Surge Protective Devices (SPD) installed on the load side of the branchcircuit overcurrent protection were required by Section 285.25 of the 2008 NEC®tobe located at least 30 feet from the service. In the 2011 NEC® this section has beenrevised to state that the requirement to install the Type 3 SPD at least 30 feet fromthe service is necessary only when specified in the manufacturers instructions. Thischange recognizes that a Type 3 SPD that has been subjected to additional testingmay be installed anywhere in the branch circuit on the load side of the overcurrentprotection. UL 1449, the Standard for Surge Protective Devices, requires a Type 3SPD 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 wirebetween the electrical outlet and the electrical service panel.” If this marking doesnot appear on the SPD or in the instruction sheet the Type 3 SPD may be installedanywhere in the branch circuit.

Type 3 SPDs are typically cord connected power strips or receptacle type devices.

SECTION 314.24

� A box must have sufficient depth for the installation of a large device orutilization equipment.

Outlet and Device Box Depth

This section of the code requires boxes to have sufficient depth toprevent damage to the conductors when devices or utilizationequipment are installed as intended in the box. Section 314.24 hasbeen revised for the 2011 NEC® to include devices. This requirementpreviously applied only to utilization equipment. Section 314.24specifies the depth of the box and the required clearance, taking intoconsideration a variety of conductor sizes.

The reorganization of Article 310 has resulted in the renumberingof most of the sections and tables and the relocation of some ofthe requirements. One notable change is that Table 310.16 for theallowable ampacities of conductors is now Table 310.15(B)(16) in the2011 NEC®. The ambient temperature correction factors have beenremoved from the allowable ampacity Tables and now appearrelocated to new section 310.15(B)(2) and Tables 310.15(B)(2)(a)and 310.15(B)(2)(b). There have also been changes to the allowableampacities for several different conductor sizes in Table 310.15(B)(16).

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

SECTION 314.27(C)Outlet Boxes for Ceiling Fans

� A box listed for support of a ceiling-suspended fan must be installedwhen a spare ungrounded conductor is provided.


Section 314.27(A) has been revised to more clearly state the outlet boxrequirements for supporting luminaires at wall and ceiling outlets.Ceiling outlet boxes intended to support a luminaire must be able tosupport at least 50 pounds. A box may be used to support a luminaireweighing more than 50 pounds if the box is listed and marked for themaximum luminaire weight to be supported.

A wall box intended to support a luminaire must be marked to indicatethe maximum weight of the luminaire to be supported, if other than50 pounds. An exception allows wall type luminaires weighing6 pounds or less to be supported by device boxes, plaster rings orother boxes when the luminaire is secured by at least two No. 6 orlarger screws.

Although the requirements in Article 390 for Underfloor Racewaysremain the same, Section 390.2 now provides a definition. UnderfloorRaceways are installed flush or beneath the floor surface and areintended for the installation of conductors. The underfloor racewaymay be equipped with junction boxes for access to the conductors aswell as a wide variety of fittings such as floor boxes and pedestals thatallow power, voice and data connectivity.

SECTION 390.2Underfloor Raceways

� A new definition for Underfloor Raceway has been added to the code.

Article 380 provides the installation requirements for MultioutletAssemblies. A new Section, 380.23, specifies the wire bending space andpull requirements for conductors in field assembled multioutlet assemblies.Section 380.23 does not apply to listed, factory assembled multioutletassemblies.

Section 380.23(A) requires insulated conductors installed in a fieldassembled multioutlet assembly to comply with the wire bending spacespecifications in Table 312.6(A). Where a multioutlet assembly is usedas 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 Section314.28(A)(2) for angle pulls.

Section 380.23 applies only to field assembled multioutlet assemblies.There was concern that conductors could be damaged when installed infield assembled multioutlet assemblies.

Another change to this Article is that Section 380.1 has been revised to addan informational note that directs the user to the definition of a MultioutletAssembly in Article 100.

SECTION 380.1 and SECTION 380.23Multioutlet Assemblies

� Field assembled Multioutlet Assemblies must comply with wire bendingspace and pull box requirements.

Grounding of Snap Switches, Dimmersand Similar Control Switches

SECTION 404.9(B) Exceptions Nos. 1, 2, & 3

� A snap switch, dimmer or similar control switch shall be connected to theequipment grounding conductor.


Page 24

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

Exceptions to Section 404.2(C) allow for future installation of the grounded circuitconductor where there is access to the switch box in cable installations or whereraceway is used to provide the conductors. In either case, the grounded circuitconductor can be provided after the initial installation.

SECTION 404.2(C)Switches Controlling Lighting Loads

� A grounded circuit conductor shall be provided at the switch location.

This section requires snap switches, dimmers and similar control switches to be connectedto 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:

Exception No. 1 – A replacement switch is not required to be connected to the equipmentgrounding conductor where the equipment grounding conductor is not available in theswitch enclosure. Where the replacement switch is installed 8 feet vertically or 5 feethorizontally from ground or grounded metal objects it must have a nonconductingfaceplate secured by nonmetallic screws or the circuit must be protected by a GFCI.

Exception No. 2 – listed switch assemblies of nonmetallic construction as described in thisnew exception are not required to be connected to the equipment grounding conductor.

Exception No. 3 – a snap switch with an integral nonmetallic enclosure as described inSection 300.15(E) is not required to be connected to the equipment grounding conductor.This type of switch is commonly known as a self contained device (SCD).

Section 406.14 has been added to the code to require that all non-locking 125 volt, 15 and 20 amp receptacles installed in child carefacilities must be tamper-resistant. Section 406.2 defines a child carefacility as a location where educational, supervision or personal careservices are provided for more than four children under the age ofseven.
