Article 770 deals with optical fiber cables. These cables have little to do with electrical installations and have more in common with Articles 800, 820, 830, and 840 installations. For this reason, it is appropriate that Article 770 be moved into Chapter 8 with other telecommunications related installations. 16-21 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770, Informational Note (Log # 627 )

Based upon the Panel Action on Proposals 16-29 and 16-30 the definition of Optical Fiber Cable should now read: "Optical Fiber Cable. A factory assembly or field assembly of one or more optical fibers having an overall covering."

Dorna, G. The panel determined that the submitter s substantiation was insufficiently detailed. It wrote To ensure that this change will not impact this article will take a review of the Chapters 1, 3, and 4 to determine that all applicable sections have been referenced in Article 770. Let s expand the detail of submitter s substantiation to the level of a review of Chapters 1, 3 and 4 Chapter 1 The submitter s statement about Chapter 1 is: 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. The table below is a detailed analysis of Chapter 1. Article Applies to Article 770? Observation 100 Definitions Part I General yes Part II Over 600 Volts- No 770.2 references Article 100. Panel action on proposal 16-27 narrows the reference to Part I of Article 100 110 Requirements for Electrical Installations No The title of the article clearly omits optical fiber cables. Likewise, the scope is clear about covering only electrical conductors. Clearly, only Part I of Article 100 applies to Article 100 and it is already referenced in 770.2, so nothing is lost by exempting Article 770 from Article 100. Chapter 4 The title of Chapter 4 is Equipment for General Use ; clearly the equipment is electrical equipment. Let s review chapter 4 in detail in the table below: Article Applies to Article 770? 400 Flexible Cords and Cables No 402 Fixture Wires No 404 Switches No 406 Receptacles, Cord Connectors, and Attachment Plugs (Caps) No 408 Switchboards and Panelboards No 409 Industrial Control Panels No 410 Luminaires, Lampholders, and Lamps No 411, Lighting Systems Operating at 30 Volts or Less No 422 Appliances No 424 Fixed Electric Space-Heating Equipment No 426 Fixed Outdoor Electric Deicing and Snow-Melting Equipment No 427 Fixed Electric Heating Equipment for Pipelines and Vessels No 430 Motors, Motor Circuits, and Controllers No 440 Air-Conditioning and Refrigerating Equipment No 445 Generators No 450 Transformers and Transformer Vaults (Including Secondary Ties) No 455 Phase Converters No 460 Capacitors No 470 Resistors and Reactors No 480 Storage Batteries No 490 Equipment, Over 600 Volts, Nominal No Each of the Articles in Chapter 4 covers a deferent type of electrical equipment and none of the Articles in Chapter 4 applies to Article 770. Chapter 3 In the current edition of the Code, only those sections of Article 300 apply to Article 770. The submitter states: Article 770 has references to 300.22 for installations in air-handling spaces and it has references to Chapter 3 for the installation of raceways. The table below is a detailed analysis of Chapter 3 (other than Article 300). Article Applies to Article 770? Observation 310 Conductors for General Wiring No 312 Cabinets, Cutout Boxes, and Meter Socket Enclosures No 314 Outlet, Device, Pull, and Junction Boxes; Conduit Bodies; Fittings; and Handhole Enclosures Yes 770.110(A)(1) already requires that the installation of Chapter 3 raceways comply with the applicable requirements of Chapter 3. 320 Armored Cable: Type AC No 322 Flat Cable Assemblies: Type FC No 324 Flat Conductor Cable: Type FCC No 326 Integrated Gas Spacer Cable: Type IGS No 328 Medium Voltage Cable: Type MV No 330 Metal-Clad Cable: Type MC No 332 Mineral-Insulated, Metal-Sheathed Cable: Type MI No 334 Nonmetallic-Sheathed Cable: Types NM, NMC, and NMS No 336 Power and Control Tray Cable: Type TC No 338 Service-Entrance Cable: Types SE and USE No 6

The numerous electrical cable articles have no relevance to Article 770. Article 770 permits installation of optical fiber cables in cable trays; see 770.113 and 770.133. Article 770 has no requirements for the installation of cable trays and the installation requirements of Article 392 would be lost. This analysis, therefore, leads to the conclusion that this proposal should be accepted in part and the addition of all of Chapter 3 should be rejected. Therefore, the introductory paragraph of 770.3 should be changed to read: Installations of optical fiber cables and raceways shall comply with 770.3(A) and (B). Only those sections of Chapters 1, 2 and 4 and Article 300 referenced in this article shall apply to optical fiber cables and raceways. 16-36 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770.3(B) (New) (Log # 429 ) 16-37 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770.3(C) (New) (Log # 708 )

The "Regulations Governing Committee Projects" state in Section 4-3.3 (d) that proposals shall include a 'statement of the problem and substantiation for Proposal'. The submitter has identified neither a fire nor an electrical safety hazard to warrant expanding the requirements of 770.24. The requirements of 300.4 are intended to promote fire and electrical safety where electrical cables containing significant voltage and available current are run within walls, floors and ceilings. Hazards may result when nails, screws or other fasteners are driven into the wall, floor or ceiling should they puncture the electrical cable. Optical fiber cables are much smaller (approximately 1/8 inch in diameter) than power cables, contain no power, and do not pose a fire or electrical safety hazard. Support of cables is presently addressed in 300.4(D). Deike, Jr., R. Optical Fiber should not be held to the same installation requirements as electrical cable. There was no substantiation provided to document that fiber optic cable presents the same level of hazard to personnel or property that electrical cable does. The level of protection required for the fiber optic cable should be determined by the end user. Dorna, G. The submitter s assertion that optical fiber cables need to be protected when installed other-then-parallel to framing members is totally unsubstantiated. Likewise the submitter s assertion that optical fiber cables require support when installed behind accessible panels is not substantiated. These no-voltage cables present no shock hazard and unlike electric power cables, they cannot initiate a fire. Article 770 already addresses the only hazard that optical fiber cables present, the hazard from the spread of fire. Ivans, R. This proposal should be Rejected. Optical fiber and communications circuits are not required to be protected the same as power, Class 1, or life safety circuits, therefore adding all the subsections in 300.4 is unnecessary. Section 90.1(A) states the purpose of the NEC is practical safe guarding of persons and property from hazards arising from the use of electricity. The requirements of 300.4 are intended to protect cables containing voltage and available current that present the risk of fire or electrical shock. Where there is only signal power, limited power or no power at all (optical fiber) in the cable, there is no reason to add excessive requirements. Johnson, S. The workmanship requirements for optical fiber cables are not the same as those required for high voltage conductors. The safety and shock hazards present in power carrying cables are not present in these types of cables. The submitter's substantiation has not shown that adding these more stringent requirements are necessary from a safety standpoint. Prezioso, L. The proposal failed to present sufficient substantiation for the added requirements and any fire or electrical safety issues that would be remedied by the change.

16-45 Eligible To Vote:16 Affirmative: 14 : 1 Abstain: 0 : 1 770.26 (Log # 710 ) Dorna, G. The current text uses the term optical fiber cables and raceways twice. The panel statement that raceways are required to be fire stopped is undisputable but is based on a misreading of the text. The raceways the submitter recommends deleting are optical fiber raceways not raceways in general. The fire stopping of raceways is covered by 300.21. Article 770 already requires the fire stopping of Chapter 3 raceways; see 770.110(A)(1). It should be noted that 830.26 does not mention raceways because there are no raceways unique to that Article. There are (or were) optical fiber raceways, communications raceways and CATV raceways; there are no network-powered-broadband raceways. Since the panel accepted the use of communications raceways in place of optical fiber raceways, it could have accepted the proposal in principle and changed optical fiber cables and raceways to optical fiber cables and communications raceways just as it did in its action to accept proposal 16-169 in principle. If the panel had accepted proposals 16-45 and 16-169, the fire stopping of communications raceways would still be required by 800.26. Affirmative with Comment Ohde, H. We agree with the panel action and panel statement that all raceways are required to be fire stopped. It does not matter if the raceway is a communication raceway or any other type of raceways. All electrical installations in these areas need to be fire stopped to prevent the possible spread of fire or products of combustion. 16-46 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770.47 (New) (Log # 437 ) 16-47 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770.48(B) (Log # 438 ) 16-48 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 770.49 (New) (Log # 195 ) Affirmative with Comment Ohde, H. We agree with the panel action however believe that that is a grounding requirement and does not belong as 770.49 in Part II Cables Outside and Entering Buildings. This grounding requirement would be best suited somewhere in Part IV Grounding Methods. 16-49 Eligible To Vote:16 Affirmative: 14 : 1 Abstain: 0 : 1 770.93(B) (New) (Log # 196 ) 10
11 Ohde, H. There is no need for this Informational Note as it is unwarranted and not necessary.

This proposal should be accepted. Communication Cables may be provided with copper conductors with additional optical fiber member(s). These cables are provided with an OF suffix. In addition, 770.3 (B) covering composite optical fiber cables, requires that they be classified as electrical cables in accordance with the type of electrical conductors provided. In the case of communications cables, article 800 would apply. Therefore, the revised definition would better describe such a composite cable. 16-85 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 800.2 Communications Raceway (Log # 199 )

18 Brunssen, J. The "Regulations Governing Committee Projects" state in Section 4-3.3 (d) that proposals shall include a 'statement of the problem and substantiation for Proposal'. The submitter has identified neither a fire nor an electrical safety hazard to warrant expanding the requirements of 800.24. The requirements of 300.4 are intended to promote fire and electrical safety where electrical cables containing significant voltage and available current are run within walls, floors and ceilings. Hazards may result when nails, screws or other fasteners are driven into the wall, floor or ceiling should they puncture the electrical cable. Communications cables are typically smaller than power cables (26 AWG copper conductors), operate at power levels of 100 volt-amperes or less derived from a power-limited source, and do not pose a fire or electrical safety hazard. Support of cables is presently addressed in 300.4(D). Deike, Jr., R. Communication circuits and equipment should not be held to the same installation requirements as electrical cable. There was no substantiation provided to document that communication circuits and equipment present the same level of hazard to personnel or property that electrical cable does. The level of protection required for communication circuits and equipment should be determined by the end user. Dorna, G. The submitter s assertion that communications cables need to be protected when installed other-then-parallel to framing members is totally unsubstantiated. Likewise the submitter s assertion that communications cables require support when installed behind accessible panels is not substantiated. Communications cables present minimal shock hazard and unlike electric power cables, they cannot initiate a fire. The uniqueness of communications circuits is recognized by 90.3 which exempts Chapter 8 from the general wiring requirements unless specifically referenced from Chapter 8. The submitter is trying to apply a uniform set of installation rules to power, communications and fiber optics without considering the inherent safety features of communications installations. Ivans, R. This proposal should be Rejected. Optical fiber and communications circuits are not required to be protected the same as power, Class 1, or life safety circuits, therefore adding all the subsections in 300.4 is unnecessary. Section 90.1(A) states the purpose of the NEC is practical safe guarding of persons and property from hazards arising from the use of electricity. The requirements of 300.4 are intended to protect cables containing voltage and available current that present the risk of fire or electrical shock. Where there is only signal power, limited power or no power at all (optical fiber) in the cable, there is no reason to add excessive requirements. Johnson, S. The workmanship requirements for communications cables are not the same as those required for high voltage conductors. The safety and shock hazards present in power carrying cables are not present in these types of cables. The submitter's substantiation has not shown that adding these more stringent requirements are necessary from a safety standpoint. Prezioso, L.

Dish antennas are presently covered in the scope of Article 810. The "Regulations Governing Committee Projects" state in Section 4-3.3 (d) that proposals shall include a 'statement of the problem and substantiation for Proposal'. The submitter has identified neither a problem nor substantiated excluding flat or parabolic (dish) antennas of less than 1 meter is diameter (or across) from article 810. Stating that flat or parabolic antennas 1 m (39.37 in) or less in diameter or across and their associated coaxial cabling "are better suited" to Article 840 is an unsubstantiated technical change.
25 Ivans, R. This proposal should be Accepted In Part. Including flat antennas and correcting the term dish to parabolic should be accepted. However, there is no technical substantiation provided why parabolic antennas 1 m or less in diameter should be excluded from Article 810 or why these should be treated differently than parabolic antennas greater than 1 m in diameter. They are all subject to lightning transients. In addition, although Article 840 covers premises powered broadband systems that deliver broadband services that an antenna might provide, the requirements were specifically developed to cover only fiber to the premises systems where there is no metallic wiring or cable members conductively connected to cabling or devices outside of the building. In order for small parabolic antennas to be included in article 840, appropriate requirements would need to be developed to cover outside cabling and antennas that may be subject to lightning transients. Finally, installation criteria and requirements would need to be developed that somehow differentiate these small parabolic antennas from other antenna systems still covered under Article 810. Johnson, S. The substantiation does not present a compelling argument for moving 1 meter and smaller diameter parabolic dishes into Article 840, while leaving larger parabolic dishes in Article 810. Prezioso, L. The proposal justification and explanation did not provide sufficient substantiation regarding why the term "dish" should be replace with a reference to a "parabolic" antenna exceeding one meter in diameter. 16-142 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 810.2 (Log # 206 ) 16-143 Eligible To Vote:16 Affirmative: 11 : 4 Abstain: 0 : 1 810.3 (Log # 2951 ) Brunssen, J. The "Regulations Governing Committee Projects" state in Section 4-3.3 (d) that proposals shall include a 'statement of the problem and substantiation for Proposal'. The submitter has identified neither a problem nor substantiated excluding flat or parabolic (dish) antennas of less than 1 meter in diameter (or across) from article 810. Stating that flat or parabolic antennas 1 m (39.37 in) or less in diameter or across and their associated coaxial cabling "are better suited" to Article 840 is an unsubstantiated technical change. See my comment supporting my negative ballot on Proposal 16-141. Dorna, G. See my Explanation of Vote on Proposal 16-260. Ivans, R. This proposal should be Rejected. There is no technical substantiation provided why parabolic antennas 1 m or less in diameter should be excluded from the requirements in Article 810 or why these should be treated differently than parabolic antennas greater than 1 m in diameter. They are all subject to lightning transients. It is not appropriate for any antennas to be installed in accordance with article 820 as a blanket requirement. For example, 820.93 (C) describes the use of a listed primary protector. This type of protector is not appropriate for antenna systems which, when protectors are used, would require an antenna lead-in protector specifically designed for antenna systems with surge current ratings. In addition, although Article 840 covers premises powered broadband systems that deliver broadband services that an antenna might provide, the requirements were specifically developed to cover only fiber to the premises systems where there is no metallic wiring or cable members conductively connected to cabling or devices outside of the building. In order for small parabolic antennas to be included in article 840, appropriate requirements would need to be developed to cover outside cabling and antennas that may be subject to lightning transients. Finally, installation criteria and requirements would need to be developed that somehow differentiate these small parabolic antennas from other antenna systems still covered under Article 810. Prezioso, L. Article 840, Network Powered Devices, was written to cover networking devices, not parabolic antennas under one meter in diameter. The proposal justification and explanation did not provide sufficient substantiation regarding why this article should cover parabolic antennas at all, much less only parabolic antennas under one meter in diameter. 16-144 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 810.6 (New) (Log # 1884 )

The proposal failed to present sufficient substantiation for the added requirements and any fire or electrical safety issues that would be remedied by the change. 16-166 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.24 (Log # 2947 ) Affirmative with Comment Ivans, R. I agree with panel action to Accept In Part with further substantiation. It is appropriate to align with NFPA 90A. Cable ties are listed under the UL certification category for Positioning Devices (ZODZ) for this purpose. 16-167 Eligible To Vote:16 Affirmative: 9 : 6 Abstain: 0 : 1 820.24 (Log # 3137 ) Brunssen, J. The "Regulations Governing Committee Projects" state in Section 4-3.3 (d) that proposals shall include a 'statement of the problem and substantiation for Proposal'. The submitter has identified neither a fire nor an electrical safety hazard to warrant expanding the requirements of 820.24. The requirements of 300.4 are intended to promote fire and electrical safety where electrical cables containing significant voltage and available current are run within walls, floors and ceilings. Hazards may result when nails, screws or other fasteners are driven into the wall, floor or ceiling should they puncture the electrical cable. Coaxial cables are much smaller (approximately 1/4 inch in diameter) than power cables, contain no power, and do not pose a fire or electrical safety hazard. Support of cables is presently addressed in 300.4(D). Deike, Jr., R. Coaxial cable should not be held to the same installation requirements as electrical cable. There was no substantiation provided to document that coaxial cable present the same level of hazard to personnel or property that electrical cable does. The level of protection required for coaxial cable should be determined by the end user. Dorna, G. See my Explanation of Vote on Proposal 16-99. Ivans, R. This proposal should be Rejected. Optical fiber and communications circuits are not required to be protected the same as power, Class 1, or life safety circuits, therefore adding all the subsections in 300.4 is unnecessary. Section 90.1(A) states the purpose of the NEC is practical safe guarding of persons and property from hazards arising from the use of electricity. The requirements of 300.4 are intended to protect cables containing voltage and available current that present the risk of fire or electrical shock. Where there is only signal power, limited power or no power at all (optical fiber) in the cable, there is no reason to add excessive requirements. Johnson, S.

30 16-169 Eligible To Vote:16 Affirmative: 14 : 1 Abstain: 0 : 1 820.26 (Log # 450 ) Ohde, H. We disagree with the panel action but think that all electrical installations in these areas need to be fire stopped to prevent the possible spread of fire or products of combustion. This requirement should not be just be limited to coaxial cables but should include all electrical installations and equipment such as all raceways, etc. Even though this proposal deals with 820.26, the 2011 NEC 830.26 should also include similar language so there can be consistency with the electrical installation of all electrical equipment where there might be a possibility of spread of fire. 16-170 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.44(D) (Log # 360 ) 16-171 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.47(A) (Log # 451 ) 16-172 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.47(B) Exception No. 2 (Log # 1751 ) 16-173 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.47(B) Exception No. 2 and 820.133(A)(2) Exception No. 1 (Log # 1907 ) 16-174 Eligible To Vote:16 Affirmative: 15 : 0 Abstain: 0 : 1 820.47(B) Exception No. 2 and 820.133(A)(2) Exception No. 1 (Log # 2880 )
