Section 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. P&S Cat. #s: 5262, 3232, 8200HI Page 1 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 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 applies if multiple circuits are supplying a multipole switch.

5 Page 2 Page 3 SECTION Readily Accessible GFCIs SECTION 210.8(A)(7) GFCI protection of Receptacles Near Sinks in Dwellings 6' GFCIs installed per must be readily accessible. Ground Fault Circuit Interrupters that provide protection for receptacles as specified in Sections (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. 15A and 20A, 125V receptacles within 6 feet of a sink in a dwelling must be GFCI protected. 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.

6 Page 4 Page 5 SECTION 210.8(B)(5) Exception No.2 to (5) GFCI Protection of Receptacles Near Sinks in Health Care Facilities SECTION 210.8(B)(6) 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. P&S Cat #s: 1595HG, 2095HG P&S Cat #s: 1595, 2095

7 Page 6 Page 7 SECTION 210.8(B)(7) GFCI Protection of Receptacles in Locker Rooms SECTION 210.8(B)(8) GFCI Protection for Receptacles in Commercial Garages 15A and 20A, 125V receptacles located in a locker room with an 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. 15A and 20A, 125V receptacles in garages where electrical diagnostic equipment, electrical hand tools or portable lighting equipment is used must be GFCI protected. GFCI protection for receptacles in dwelling unit garages is required by Section 210.8(A)(2). Section 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. P&S Cat #s: 1595, 2095 P&S Cat #s: 1595, 2095

8 Page 8 Page 9 SECTION (A) Exception 1&2 Arc-Fault Circuit Interrupter (AFCI) Protection of Outlets in Dwellings SECTION (B) Arc-Fault Circuit Interrupter (AFCI) Protection of Outlets in Dwellings A Receptacle Type AFCI may provide protection of the branch circuit. In the 2008 NEC the definition for an AFCI was in section (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 (B) in the 2008 NEC have been moved to section (A). Section (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 (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. A Circuit Breaker or Receptacle Type AFCI must provide protection of branch circuit extensions and modifications. Section (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, (B), has been added to require AFCI protection for branch circuit modifications and extensions of the circuits specified in Section (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 (B).

9 Page 10 Page 11 SECTION (A)(2)(1) Receptacle Spacing in Dwelling Units SECTION (A)(4) Countertop Receptacles Fixed cabinets are not included in determining the unbroken wall space for receptacle spacing. Section (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 (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. Receptacles serving countertops are not considered as meeting the general provisions for receptacle spacing. A new section, (A)(4), has been added to make it clear that the countertop receptacles installed to comply with Section (C) may not be considered as the receptacles that meet the general provision installation requirements for receptacles in Section (A). The countertop receptacles are intended to serve the appliances that are used on a countertop space. P&S Cat #s: 885, 3232, 885TR, 3232TR P&S Cat #s: 885, 3232, 885TR, 3232TR

10 Page 12 Page 13 SECTION (C)(4) Separate Countertop Spaces SECTION (C)(5) and (D) Receptacles in Kitchen and Bathroom Countertops Receptacles are required in separate countertop spaces. 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 (C) to subsection (C)(4). Although the requirement has not changed, it was recognized that Section (C)(4) is the section that deals with separate countertop spaces. Listed receptacle assemblies may be installed in kitchen and bathroom countertops. Section 406.4(E) prohibits the installation of receptacles in a face up position in countertops. However, sections (C)(5) and (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.

11 Page 14 Page 15 SECTION (E)(3) Receptacles on Balconies, Decks and Porches SECTION (G) 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 ft 2 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.

12 Page 16 Page 17 SECTION (I) Receptacle Outlets in Dwelling Unit Foyers SECTION Type 3 Surge-Protective Devices (Transient Voltage Surge Suppressors) Receptacles must be installed in foyers. 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 SPDs are permitted to be installed on the load side of the branch circuit overcurrent protection. Type 3 Surge Protective Devices (SPD) installed on the load side of the branch circuit overcurrent protection were required by Section 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. P&S Cat #s: 885TR, 3232TR P&S Cat. #s: 5362GRYSP, TR5362GRYSP, PT5362GRYSP Wiremold Cat. #s: M6BZ, M6S

13 Page 18 Page 19 ARTICLE 310 Conductors for General Wiring SECTION Outlet and Device Box Depth Article 310 has been reorganized and renumbered. The reorganization of Article 310 has resulted in the renumbering of most of the sections and tables and the relocation of some of the requirements. One notable change is that Table for the allowable ampacities of conductors is now Table (B)(16) in the 2011 NEC. The ambient temperature correction factors have been removed from the allowable ampacity Tables and now appear relocated to new section (B)(2) and Tables (B)(2)(a) and (B)(2)(b). There have also been changes to the allowable ampacities for several different conductor sizes in Table (B)(16). A box must have sufficient depth for the installation of a large device or utilization equipment. This section of the code requires boxes to have sufficient depth to prevent damage to the conductors when devices or utilization equipment are installed as intended in the box. Section has been revised for the 2011 NEC to include devices. This requirement previously applied only to utilization equipment. Section specifies the depth of the box and the required clearance, taking into consideration a variety of conductor sizes. Wiremold Cat #s: V2400D, MC-V2400BC P&S Cat #s: S118R, S122R, P118R, P122R

14 Page 20 Page 21 SECTION (A) Outlet Boxes for Luminaires SECTION (C) Outlet Boxes for Ceiling Fans Outlet boxes are permitted to support luminaires in walls and ceilings. Section (A) has been revised to more clearly state the outlet box requirements for supporting luminaires at wall and ceiling outlets. Ceiling outlet boxes intended to support a luminaire must be able to support at least 50 pounds. A box may be used to support a luminaire weighing more than 50 pounds if the box is listed and marked for the maximum luminaire weight to be supported. 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. A box listed for support of a ceiling-suspended fan must be installed when a spare ungrounded conductor is provided. 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 (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. P&S Cat #s: 55501, S120RAC, S120HAC, C118WAC, S118W P&S Cat #s: 55025, 55501,

15 Page 22 Page 23 SECTION and SECTION Multioutlet Assemblies SECTION 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, , specifies the wire bending space and pull requirements for conductors in field assembled multioutlet assemblies. Section does not apply to listed, factory assembled multioutlet assemblies. Section (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 (B) requires compliance with Section (A)(1) for straight pulls and Section (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 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 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 has been revised to add an informational note that directs the user to the definition of a Multioutlet Assembly in Article 100.

16 Page 24 Page 25 SECTION 404.2(C) Switches Controlling Lighting Loads SECTION 404.9(B) Exceptions Nos. 1, 2, & 3 Grounding of Snap Switches, Dimmers and Similar Control Switches A grounded circuit conductor shall be provided at the switch location. 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. 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. A snap switch, dimmer or similar control switch shall be connected to the equipment grounding conductor. 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: Exception No. 1 A replacement switch is not required to be connected to the equipment grounding conductor where the equipment grounding conductor is not available in the switch enclosure. Where the replacement switch is installed 8 feet vertically or 5 feet horizontally from ground or grounded metal objects it must have a nonconducting faceplate 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 this new 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 in Section (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). P&S Cat #s: PTWSP250, WDT100, WSP250 P&S Cat #s: PS20AC1, PT20AC1, CSB15AC1, TM870, 660

17 Page 26 Page 27 SECTION (F) Snap Switch Rating for Plug and Cord Connected Loads SECTION and Tamper-Resistant Receptacles in Child Care Areas Snap switches must be rated not less than the rating of the overcurrent device protecting the circuit. This new section establishes the rating of a switch used to control receptacle outlets. The switch must be rated not less than the rating of the overcurrent device protecting the circuit. The exception permits the switch to be rated not less than the receptacle rating where the switch controls only one receptacle. Tamper-resistant receptacles are required in child care facilities. Section has been added to the code to require that all nonlocking 125 volt, 15 and 20 amp receptacles installed in child care facilities must be tamper-resistant. Section defines a child care facility as a location where educational, supervision or personal care 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.

This new section requires AFCI protection for a replacement receptacle. When a replacement receptacle is installed on a branch circuit that requires AFCI protection, the replacement receptacle must be provided with AFCI protection. Branch circuits that require AFCI protection are specified in Section AFCI protection for the replacement receptacle may be provided by one of the following methods: - the replacement receptacle is a listed Outlet Branch Circuit type AFCI - the replacement receptacle may be protected by a listed Outlet Branch Circuit type AFCI receptacle located upstream from the replacement receptacle - a listed combination type AFCI circuit breaker providing protection of the branch circuit Replacement receptacles must be tamper resistant where tamperresistant receptacles are required by the code. Sections , , and (C) require the installation of listed tamper-resistant receptacles in child care facilities, guest rooms, guest suites, specified areas of dwelling units and pediatric locations. Section 406.4(D)(5) is a new section that requires a replacement receptacle to be tamper-resistant when installed in any of the locations specified in the code that require a tamper-resistant receptacle.

20 Page 33 Page 32 SECTION 406.9(B)(1) SECTION Receptacles in Wet Locations Tamper-Resistant Receptacles for Dwelling Units Extra Duty While-In-Use Covers are required when the outlet box is Section 406.9(B)(1) requires a weatherproof cover for 15 and 20 amp, 125 and 250 volt receptacles installed in wet locations. These covers, 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. P&S Cat #s: WIUCAST1, WIUC10 15A and 20A, 125V receptacles in dwellings must be listed tamper resistant. supported from grade. This section was previously added to the code in response to the numerous reported electrical injuries to children resulting from the insertion of conductive foreign objects into receptacles. Section requires that 15 and 20 amp, 125 volt receptacles in all areas of dwellings specified in Section must be tamper-resistant. Section has been revised to allow exceptions to the tamperresistant receptacle requirement. The exceptions include receptacles located more than 5-1/2 feet above the floor, receptacles in a dedicated space for appliances that cannot be easily moved and receptacles that are part of a luminaire or appliance. The exceptions recognize that there are receptacles that cannot be easily reached by children and there are receptacles specified in Section that are not considered to meet the receptacle installation requirements in dwellings. In addition, Section has been revised to limit the tamper-resistant requirement to the nonlocking type of receptacle. P&S Cat #s: 1595TR, 885TR, TM8HWLTR, 3232TR

Section is a new Section that requires nonlocking 15 and 20 amp, 125 volt receptacles in guest rooms and guest suites to be tamper-resistant. Guest rooms and guests suites are defined in Article 100 of the NEC. These locations are often occupied by children and present hazards similar to other locations such as dwellings that require tamper-resistant receptacles. Motors may be connected to the branch circuit by a plug and receptacle or a cord connector. The motor disconnect may be a plug and receptacle or a flanged surface inlet and a cord connector. Both of these sections have been revised to recognize that a motor may be connected to the branch circuit by not only a plug and receptacle but also by a cord connector. Per Section (A), a cord connector may be supplied by a permanently connected cord pendant. Section (F) has been revised to include a flanged surface inlet and cord connector as a motor disconnect means. Previously, this section recognized only a plug and receptacle as the disconnect means.

22 Page 36 Page 37 SECTION (B)(1)(2) Grounding of Receptacles in Patient Care Areas of Health Care Facilities SECTION Isolated Ground Receptacles in Health Care Facilities This section is restructured to provide the requirements for the connection of the insulated equipment grounding conductor in patient care areas. The revisions to Section (B) are intended to more clearly state the requirements for the connection of the insulated equipment bonding conductor to receptacles, metal boxes and non-current carrying conductive surfaces. An exception permits an equipment bonding jumper to connect the receptacle and box to the equipment grounding conductor. Isolated ground receptacles are no longer permitted in patient care areas. Section has been revised to prohibit the use of isolated ground receptacles in patient care areas. There was concern that the redundant grounding required by Sections (A) and (B) may not be adequately achieved when using isolated ground receptacles.

23 Page 38 Page 39 SECTION (B) and (B)(2) Patient Bed Location Receptacles in Health Care Facilities SECTION (A) Receptacles in Wet Procedure Location Patient Care Areas Patient bed location receptacles may be single, duplex or quadruplex. The requirements for patient bed receptacles in general care areas and critical care areas have been revised to include quadruplex receptacles, in addition to single and duplex receptacles, as the type of receptacles that may be installed to meet the minimum receptacle requirements for theses areas. The power distribution system must limit the ground fault current. Section (A), titled Receptacles and Fixed equipment, requires the power distribution system in wet procedure patient care areas to either limit the ground fault current due to a first fault to a low value without interrupting the power, or, to interrupt the power supply if the ground fault current exceeds 6 ma. The revision to this section closely parallels the wording in NFPA 99, Section P&S Cat #s: 420HI, 8201, 8200HI P&S Cat #s: 8300HI, PTTR8300, 8300W, PT8300

24 Page 40 Page 41 SECTION 518.3(B) Temporary Wiring in Exhibition Halls SECTION GFCI Protection for Carnivals, Circuses, Fairs Ground fault circuit interrupter protection required in exhibition halls. Temporary wiring in exhibition halls may be installed in accordance with Article 590, with the exception that the ground fault circuit interrupter (GFCI) requirements of do not apply. However, section 518.3(B) has been revised to state that all other GFCI requirements in the code apply in this type of installation. An additional revision to this section requires that portable GFCIs must meet the requirements for a listed product. This effectively means that portable GFCIs should be listed products. GFCI protection is required for 15A and 20A, 125V nonlocking receptacles. Section (A) has been rewritten to clearly state in enforceable language the requirement for GFCI protection of 15A and 20A, 125V receptacles. Section (B) previously stated that receptacles are not required to be GFCI protected if the receptacles are of the locking type and they are used for the quick connect and disconnect of equipment. A revision to this section includes the additional condition that the receptacles that are unprotected by a GFCI must also not be accessible from grade level.

Section (B) specifies the receptacles that must be GFCI protected in mobile and manufactured homes. This section has been revised to delete the exception which allowed receptacles not to be GFCI protected where the receptacles were installed for use with appliances in a dedicated space. This section now references the exceptions in Section 210.8(A) as the only permitted exceptions. Receptacles shall not be installed within or directly over a bathtub or shower stall. This section restricted the installation of a receptacle within a bathtub or shower stall. In addition to the previous wording of the requirement, the section has been revised to make it clear that a receptacle may not be installed directly over a bathtub or shower stall.

26 Page 44 Page 45 SECTION AFCI Protection of Branch Circuits in Mobile/Manufactured Homes SECTION (L) and SECTION (K) Receptacle Faceplates in Recreational Vehicles and Park Trailers Additional 15 and 20A, 120V branch circuit outlets must be AFCI protected. This section previously required AFCI protection for 120V branch circuits that supply 15A and 20A receptacles installed in bedrooms. In addition to the AFCI protection for bedroom branch circuits, Section has been revised to require AFCI protection for 120 volt branch circuits supplying 15A and 20A receptacles in family rooms, dining rooms, living rooms, parlors, libraries, dens, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas. The AFCI protection must comply with Section (B). Faceplates must comply with Section 406.5(A) and (C). The title of Section (L) and Section (K) has been changed to Receptacle Faceplates. Both sections have been revised to refer to Section 406.5(A) and (C) for the specific requirements for metallic and nonmetallic faceplates. P&S Cat #s: 5262, TP8

27 Page 46 Page 47 SECTION (A) Park Trailer Outdoor Receptacles and Switches SECTION 590.4(D)(2) Receptacles in Temporary Installations Switches and receptacles must meet outdoor installation requirements. In the 2008 NEC, outdoor receptacles on park trailers had to be provided with a gasketed cover for use in wet locations. Section (A) has been revised to require outdoor receptacles to comply with Sections 406.8(A) and (B). A requirement for outdoor switches to comply with Section has also been added to this section. These revisions make certain that the appropriate protection is provided for switches and receptacles installed outdoors. Receptacles in wet locations in temporary installations must meet the requirements in section 406.9(B)(1). Section 509.6(D)(2) is a new section that requires receptacles that are in wet locations in temporary installations to comply with Section 406.9(B)(1). This change in the code recognizes that receptacles in temporary installations will be exposed to the same wet locations environment as any other outdoor installation and must be provided with the necessary protection to ensure continued safe operation of the receptacle.

28 Page 48 Page 49 SECTION 604.6(A)(5) Manufactured Wiring Systems SECTION 625 Electric Vehicle Charging System Section provides the construction requirements for Manufactured Wiring Systems. Section 604.6(A)(5) is a new section that specifies listed prewired, modular, surface raceway as one of the construction components of a manufactured wiring system. This type of surface raceway construction when used as a manufactured wiring system has a rating of 600 volts, 20 amps. A listed surface raceway intended for use as a manufactured wiring system is evaluated to UL 183, the Standard for Manufactured Wiring Systems. The code also covers other types of surface raceway products, such as Multioutlet Assemblies in Article 380 and Surface Metal and Nonmetallic Raceways in Articles 386 and 388. These products are evaluated to UL5 and UL5A, the standards for metal and nonmetallic surface raceways. A prewired, modular, surface raceway that is a component of a Manufactured Wiring System must meet the requirements of Article 604. Other surface raceway type products must meet the requirements of the code article that applies, such as, Article 380, Multioutlet Assemblies, Article 386, Surface Metal Raceways and Article 388, Surface Nonmetallic Raceways. Article 604 applies only to Manufactured Wiring Systems. Article 625 includes a definition for the Plug-In Hybrid Electric Vehicle (PHEV). A PHEV is a type of electric vehicle powered by both an electric motor and an internal combustion engine. Both all-electric vehicles and PHEV s can be charged using cord connected Electric Vehicle Supply Equipment. These are electric vehicle chargers that have a plug for connection to the EV inlet and also have a means for connection to the premises wiring to provide power. The 120 volt charger is typically a portable unit that plugs into a standard NEMA 5-15 or 5-20 receptacle. There is also a 240 volt charger that provides a faster charge time. The NEC requires that all chargers have a number of integral safety features, including personnel protection against electric shock.
