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 225.10 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. 16-2 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 3.2.1 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 770. 10

Peri, Communications Cable & Connectivity Association Add new text as follows: (new) The definition in 800.2, the applications in 800.154, and installation rules in 800.110 and 800.113 shall apply to Article 770. The listing requirements for cable routing assemblies are in 800.182 and are recommended to be deleted from 770.182 by a companion proposal, the applications of cable routing assemblies recommended to be moved from 770.154 to 800.154 and the definition moved from 770.2 to 800.2. The proposal correlates with those companion proposals. 16-38 Log #709 NEC-P16 Frank W. Peri, Communications Cable & Connectivity Association Delete 770.12. 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 770.12, which deals with using optical fiber raceways as innerduct, becomes meaningless once optical fiber raceways are eliminated. A companion proposal for 800.12 (new) permits communications raceways to be used as innerduct. 17

16-39 Log #436 NEC-P16 Stanley Kaufman, CableSafe Inc. Optical fiber cables shall be installed in a neat and workmanlike manner. Cables installed exposed on the surface of ceilings and sidewalls shall be supported by the building structure in such a manner that the cable will not be damaged by normal building use. Such cables shall be secured by hardware including straps, staples, cable ties, hangers, or similar fittings designed and installed so as not to damage the cable. The installation shall also conform with to 300.4(D) and 300.11. This is an editorial proposal to correct grammar and to make this section parallel to 800.24, 820.24 and 830.24. 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. 16-40 Log #1572 NEC-P16 David Clements, International Association of Electrical Inspectors Optical fiber cables shall be installed in a neat and workmanlike manner. Cables installed exposed on the surface of ceilings and sidewalls shall be supported by the building structure in such a manner that the cable will not be damaged by normal building use. Such cables shall be secured by hardware including straps, staples, cable ties, hangers, or similar fittings designed and installed so as not to damage the cable. The installation shall also conform with 300.4 (D) (A) through (G) and 300.11. In addition to the physical protection required in 300.4(D) regarding distance from parallel framing members, optical fiber cable also needs to be protected when installed other-than-parallel to framing members such as perpendicular through bored holes and notches in wood framing, holes in metallic framing, in shallow grooves, under roof decking, etc. Cables also require support when installed behind accessible panels. The reference needs to be to 300.4(A) through (G) not just to (D). 18

16-42 Log #3358 NEC-P16 Gregg Lytle, Solvay Solexis Optical fiber cables shall be installed in a neat and workmanlike manner. Cables installed exposed on the surface of ceilings and sidewalls shall be supported by the building structure in such a manner that the cable will not be damaged by normal building use. Such cables shall be secured by hardware including straps, staples, cable ties, hangers, or similar fittings designed and installed so as not to damage the cable. The installation shall also conform with 300.4(D) and 300.11. 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 568-2001,, ANSI/NECA/FOA 301-2004,, and other ANSI-approved installation standards. Informational Note No. 2: See NFPA 90A-2009,, for discrete combustible components installed in accordance with 300.22(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 (4.3.11.2.6.5) and raised floor plenums (4.3.11.5.5.6). 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
