■ 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.

■ 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.

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.

Outlets in Dwellings
■ 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).

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.

The conditions describing when a countertop space is divided into
separate countertop spaces by a counter-mounted cooking unit,
range or sink have been moved from the general Section 210.52(C) to
subsection 210.52(C)(4). Although the requirement has not changed, it

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.

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.

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.

■ 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:
Exceptions to Section 404.2(C) allow for future installation of the grounded circuit
conductor where there is access to the switch box in cable installations or where
raceway is used to provide the conductors. In either case, the grounded circuit
conductor can be provided after the initial installation.
Exception No. 3 – a snap switch with an integral nonmetallic enclosure as described in
Section 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).

services are provided for more than four children under the age of
seven. This change in the code recognizes that even in supervised
facilities, such as child care areas, children have access to electrical
receptacles and the potential for shock and burn incidents exist if a
child inserts a foreign object into a receptacle.

commonly referred to as While-In-Use covers, provide protection for
the receptacles both when a plug is inserted and when there is no plug
inserted into the receptacle. 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.”
