6 16-1 Log #1170o NEC-P16 Russell LeBlanc, The Peterson School In articles 90 through 830, if the wording is not already there, then add the words (or other structure(s)) after the word BUILDING(S) wherever the intent of the requirement is to also include STRUCTURES as well as buildings. There is a flaw in the NEC. The term "building" is used over 1000 times in the NEC, and in most of the cases the words "or other structure" should follow and apply the same requirements to bridges, billboards, towers, tanks, and other structures that are by definition NOT BUILDINGS. One specific example I can use is section Wiring on Buildings. I believe that this section is also intended to be applied structures, but the wording "or other structures" is not in the heading or the paragraph. There are literally thousands of other instances throughout the code that this same problem exists. This can easily be seen by doing an electronic search for the word "building". In some cases the words "or other structure" (or similar wording) are present, but in the vast majority where the requirements should also be applied to structures other than buildings, the wording is not there Log #921o NEC-P16 Joe Tedesco, Boston, MA The term "adequate" and "adequately" and "inadequately" and "inadequate" should be replaced with terms that can be properly enforced and understood. Terms are not defined and are considered vague and unenforceable per Table in the NEC Style Manaual. They are all "incorrect" 148 times in the NEC. 1

Relocate Article 770 to Chapter 8 and renumber as Article 870. Although optical fiber cable may also be used in signaling applications, the preponderance of applications today is in the area of telecommunications. Where the optical fibers are associated with power conductors (i.e., in composite cables) they are presently required to be classified as electrical cables in accordance with the type of electrical conductors contained in the composite cable [see 770.3(B)]. It is therefore appropriate that Article 770 be incorporated in Chapter 8. Relocation of Article 770 to Chapter 8 will facilitate usability of the NEC and have no impact on existing requirements. Optical fiber cables will still be able to be used for data applications, just as communications cables are used for data applications in addition to their primary applications. I was on the task group that introduced Article 770. It is not a coincidence that the organization of Article 770 follows closely the organization of Article 800. I wrote the first draft of Article 770 by modifying the text of Article 800. The task group did not consider which chapter it belonged in. When we finished writing the proposal for the new article, Sandy Egesdal, a well known fire alarm expert, suggested that there was room for the new article right after Article 760. That s how we got Article

Alliance for Telecommunications Industry Solutions (ATIS) Add text as second sentence to introductory Informational Note as follows: See Informational Note Figures 800(a) and 800(b) for illustrative application of a bonding conductor or grounding electrode conductor. The introductory IN of 770 is incomplete as stated. It fails to inform the reader as to the difference in application between a bonding conductor and a grounding electrode conductor. Without reference to the figures, the application is unclear as the terms appear throughout the Article Log #194 NEC-P16 Stanley Kaufman, CableSafe Inc. See Part I of Article 100. For purposes of this article, the following additional definitions apply. This is an editorial proposal to bring about compliance with Section of the 2003 National Electrical Code Style Manual which states: References shall not be made to an entire article, such as grounded in accordance with Article 250 unless additional conditions are specified. References to parts within articles shall be permitted. This is one of a group of Proposals prepared by the CMP-16 Definitions Task Group. The task group reviewed all definitions in Articles 770,800, 810, 820, 830 and 840 and submitted proposals to bring about compliance with the NEC Style manual, to correct errors and to establish new definitions where needed.

The task group reviewed all definitions in Articles 770,800, 810, 820, 830 and 840 and submitted proposals to bring about compliance with the NEC Style manual, to correct errors and to establish new definitions where needed. The Task Group members are: Representing: Insulated Cable Engineers Association Inc. Representing: Underwriters Laboratories Inc.

Alliance for Telecommunications Industry Solutions (ATIS) Revise as follows: A factory assembly of one or more optical fibers, having an overall covering a cable sheath., that transmits light for control, signaling, and communications. The medium (light) and function (control, signaling) is not pertinent to the definition. Replacing the term overall covering (undefined) with the term cable sheath, correlates with the definition in Log #916 NEC-P16 Thomas Guida, TJG Services, Inc. Revise the definition of Optical Fiber Cable to read as follows: A factory assembly or field assembly of one or more optical fibers, having an overall covering, that transmits light for control, signaling and communications. Underwriters Laboratories lists field-assembled optical fiber cables that are not covered by the present wording of this definition. An excerpt from the UL Guide information is shown below. This category covers field-assembled optical fiber cable, which is an on-site assembly of one or more optical fiber units and an optical fiber jacket. Field-assembled optical fiber cable is intended for installation in buildings in accordance with Article 770 of ANSI/NFPA 70, "National Electrical Code" (NEC). The optical fiber jacket is installed in a manner similar to conduit or raceway. Once the jacket is installed, the optical fiber units are inserted into the jacket, completing the assembly. 14

Add new text to read as follows: The point within a building at which the cable emerges from an external wall, from a concrete floor slab, or from a rigid metal conduit (Type RMC) or an intermediate metal conduit (Type IMC) connected by a bonding conductor or grounding electrode in accordance with (B). The definition of Point of Entrance could be construed to contain a requirement in violation of Section of the NEC Style Manual. This proposal addresses that issue by deleting the grounding requirement. A companion proposal moves it to new Section This is one of a group of Proposals prepared by the CMP-16 Definitions Task Group. The task group reviewed all definitions in Articles 770,800, 810, 820, 830 and 840 and submitted proposals to bring about compliance with the NEC Style manual, to correct errors and to establish new definitions where needed.

The term grounding conductor was changed to either bonding conductor or grounding electrode conductor in several sections during the processing of the 2011 NEC. The term grounding conductor in this definition should be changed to correlate with the other changes that were made. 15

21 16-34 Log #622 NEC-P16 James E. Brunssen, Telecordia Technologies Inc. / Rep. Alliance for Telecommunications Industry Solutions (ATIS) Revise as follows: The point within a building at which the wire or cable emerges from an external wall, from a concrete floor slab, or from a rigid metal conduit (Type RMC) or an intermediate metal conduit (Type IMC) connected by via a bonding conductor or grounding electrode conductor to an a grounding electrode in accordance with (B). The present wording is inconsistent with the 2011 revisions made to the identical definition in other articles. The proposed revisions incorporate the global revision in the 2011 NEC replacing the term grounding conductor with the terms bonding conductor or grounding electrode conductor and provides correlation throughout Articles 770, 800, 820 and 830. Replacing by with via indicates a path to the grounding electrode, not necessarily a direct connection to the grounding electrode. The term electrode is undefined; grounding electrode is defined in Article Log #434 NEC-P16 Stanley Kaufman, CableSafe Inc. Installations of optical fiber cables and raceways shall comply with 770.3(A) and (B). Only those sections of Chapters 1 through 4 2 and Article 300 referenced in this article shall apply to optical fiber cables and raceways. There are very few requirements in Chapter 2, Wiring and Protection, Chapter 3, Wiring Methods and Chapter 4, Equipment for General Use that apply to the installation of optical fiber cables and raceways. It is unreasonably burdensome to expect installers of optical fiber cables, cables which present no electrical hazards, to figure out for themselves which requirements in Chapters 2, 3 and 4 are appropriate for these no-voltage cables. Article 770 has references to for installations in air-handling spaces and it has references to Chapter 3 for the installation of raceways. Chapter 1, General has two parts that apply to optical fiber cables and raceways, definitions in Article 100 and the requirement to use and install listed and labeled equipment in accordance with the manufacturer s instructions are referenced Article 770. The rest of Chapter 1 is not needed for optical fiber cable and raceway installations. This is one of a group of Proposals prepared by the CMP-16 Special Editorial Task Group. The goals of the task group were to: 1) place requirements in the appropriate sections; 2) improve the parallelism between related Articles such that similar requirements are stated the same way in each Article; 3) make the Articles as self-sufficient as is reasonably possible; and, 4) improve the language in the difficult to understand Sections. The Task Group members are Jim Brunssen, Sandy Egesdal, Steve Johnson Stan Kahn, Stan Kaufman, David Lettkeman, Bill McCoy and Harry Odhe. 16

22 16-36 Log #429 NEC-P16 James E. Brunssen, Telecordia Technologies Inc. Add new text to read as follows: The requirements of (A) for wiring systems shall apply to conductive optical fiber cables. Renumber the existing 770.3(B) to 770.3(C). Adding this requirement for optical fiber cable correlates with a similar requirement in 800.3, as well as companion proposals to include the requirement in 820.3, and Only conductive optical fiber cables are cited as nonconductive optical fiber cables do not pose a hazard. This is one of a group of Proposals prepared by the CMP-16 Special Editorial Task Group.

The listing requirements for cable routing assemblies are in and are recommended to be deleted from by a companion proposal, the applications of cable routing assemblies recommended to be moved from to and the definition moved from to The proposal correlates with those companion proposals Log #709 NEC-P16 Frank W. Peri, Communications Cable & Connectivity Association Delete This proposal is one of a series of proposals to simplify the types of raceways specified in Articles 770, 800 and 820. Optical fiber, communications and CATV raceways are identical raceways with different markings. CMP 16 eliminated CATV raceways from the 2011 NEC. Acceptance of a companion proposal will delete optical fiber raceways and leave one type of raceway, communications raceways, to be used for optical fiber, communications and CATV cable use. Section , which deals with using optical fiber raceways as innerduct, becomes meaningless once optical fiber raceways are eliminated. A companion proposal for (new) permits communications raceways to be used as innerduct. 17

The installation shall also conform with 300.4(D) and Cable ties used to secure optical fiber plenum cables in other space used for environmental air (plenums) shall be listed as having low smoke and heat release properties. Informational Note No. 1: Accepted industry practices are described in ANSI/NECA/BICSI ,, ANSI/NECA/FOA ,, and other ANSI-approved installation standards. Informational Note No. 2: See NFPA 90A-2009,, for discrete combustible components installed in accordance with (B) and (C). Informational Note No.2: See for information on listing discrete products as having low smoke and heat release properties. The Standards Council has assigned primary responsibility for combustibles in air handling spaces to the Technical Committee on Air-Conditioning and its Standard NFPA 90, NFPA 90A-2012 has requirements for cable ties in ceiling cavity plenums ( ) and raised floor plenums ( ). These plenums are called Other Spaces Used for Environmental Air (Plenums) in the NEC. The two relevant sections of NFPA 90A are shown below: Loudspeakers, recessed lighting fixtures, and other electrical equipment with combustible enclosures, including their assemblies and accessories, cable ties, and other discrete products, shall be permitted in the ceiling cavity plenum where listed as having a maximum peak optical density of 0.5 or less, an average optical density of 0.15 or less, and a peak heat release rate of 100 kw or less when tested in accordance with ANSI/UL 2043, Loudspeakers, recessed lighting fixtures, and other electrical equipment with combustible enclosures, including their assemblies and accessories, cable ties, and other discrete products, shall be permitted in the raised floor plenum where listed as having a maximum peak optical density of 0.5 or less, an average optical density of 0.15 or less, and a peak heat release rate of 100 kw or less when tested in accordance with ANSI/UL 2043, The purpose of this proposal is to bring the NEC into correlation with NFPA 90A by requiring that cable ties installed in Other Spaces Used for Environmental Air be listing as having low smoke and heat release rates properties. Adopting this proposal will require that cables ties used with plenum grade cables will also be plenum grade; which would be a sensible proposal even if correlation with NFPA 90A were not required. Informational Note No.2 in the current code is simply not enough, a mandatory requirement is needed to correlate with NFPA 90A. Plenum grade cable ties are available on the market today. Adoption of this proposal would not require the invention of a new product. 20
