To: NEC Code-Making Panel 16

From: Kimberly Shea, Project Administrator

Date: April 16, 2015

Subject: NEC First Draft TC FINAL Ballot Results (A2016)

According to the final ballot results, all First Revisions received the necessary affirmative votes to pass ballot.

17 Members Eligible to Vote 0 Members Ballots Not Returned 4 Members voted Affirmative with Comment on one or more Revisions (Brunssen Dorna, Ivans,

McCoy) 8 Members voted Negative on one or more Revisions (Brunssen, Dorna, Ivans, Johnson, Lawrence,

Moore, Ohde, Prezioso) 0 Abstentions on one or more Revisions

The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each first revision. There are two criteria necessary for each first/second revision to pass ballot: (1) simple majority and (2) affirmative 2/3 vote. The mock examples below show how the calculations are determined. (1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative

votes are required to pass ballot. (Sample calculation: 20 members eligible to vote ÷ 2 = 10 + 1 = 11) (2) Example for Affirmative 2/3: Assuming there are 20 vote eligible committee members and 1 member did

not return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligble to vote – 1 not returned – 2 abstentions = 17 x 0.66 = 11.22 = 12 )

As always please feel free to contact me if you have any questions.

Committee Statement

CommitteeStatement:

CMP-16 edits the title of the article. Optical fiber raceways have been deleted from this article. ThisFIRST REVISION changes the title to Article 770 back to the title it had from its introduction into the1984 edition through the 1990 edition. When optical fiber raceways were added to Article 770 inthe1993 edition, the title was changed to Optical Fiber Cables and Raceways. Optical fiber racewayswere removed from the 2014 edition (replaced by communications raceways) but the Article title wasnot changed. The Article title should accurately reflect the contents of the Article.

The Panel recognizes that Article titles are the responsibility of the Correlating Committee andrecommends that the Correlating Committee concur with this FIRST REVISION.

VI. Premises Powering of Communications Equipment over Communications Cables

Informational Note: This Part addresses types of circuits intended to provide power over coaxial cables andcommunications wires and cables to remote equipment, including systems such as Power over Ethernet(PoE). These premises-powering systems do not include circuits such as those that provide plain oldtelephone services (POTS), traditional CATV services and similar legacy communications services.

840.160 Powering Circuits. Communications cables, in addition to carrying the communications circuit,shall also be permitted to carry circuits for powering communications equipment. The communicationscables and the powering circuits shall comply with 840.160(A), (B) and (C), as applicable.

(A) Power Limitations. The power circuits shall comply with the requirements of Table 11(B) in Chapter 9for voltage sources up to 60 V dc.

Informational Note: The 100 VA (100 W) power source maximum nameplate rating in Chapter 9, Table 11(B)is the same as the maximum power rating for network-powered broadband communications systems inTable 830.15, the communications industry standard in ATIS-0600337.2010 and UL 60950-21.

(B) Ampacity. The maximum current carried by each communications conductor shall conform to Table840.160(A).

Informational Note: The ampacity of the small wire gauges used in communications cables are not includedin the ampacity tables in Article 310.

(C) Installations of New Cables. New cables installed for carrying both communications and power, wherethe maximum adjusted ampacity of conductors exceed the values in Table 840.160(A), shall be TypeCMP-LP, CMR-LP or CM-LP, as applicable.

( D) Using Cables Without the “LP” Marking for Supplying Premises Power and Communications.New and existing cables without the “LP” marking shall be permitted to connect to communicationsequipment that supplies communications and power in accordance with the voltage and power limitations ofTable 11(B) in Chapter 9 for voltage sources up to 60 V dc, provided that the maximum current supplied bythe power source is less than the adjusted ampacity of conductors in Table 840.160(A). For ambienttemperatures other that 30°C (86°F) ampacity shall be permitted to be adjusted per Table 310.15(B)(2)(a).

each successive revision of the PoE standards delivers more power to the powered devices raisingconcern about overheating of the cables. Bundling and bunching of cables carrying power tocommunications equipment can result in heating. No conductor (or cable) should be used in such amanner that its operating temperature exceeds the maximum temperature it was rated for. Sections770.179 and 800.179 require that optical fiber cables and communications cables have a temperaturerating of not less than 60°C (140°F). Where cables carrying communications and power are installed,cables rated for temperatures above 60°C (140°F) may be required. How much higher is dependenton many factors, including ambient temperature, spacing and ventilation among cable bundles andbunches, wire gauge and power being dissipated in the cables.

The new Part VI provides for the use of new cables with properties chosen to be safe in worst-caseinstallation conditions. The listing requirements for these cables are in 840.170. Similar to CMP-CI,CMR-CI and CM-CI cables, the new cables are marked Types CMP-LP, CMR-LP and CM-LP. Thesecables are listed to have adequate ampacity (wire gauge) and temperature rating for worst-caseambient thermal conditions e.g., a hot attic, and worst case heating produced by the maximumpermissible current being carried by the cables.

The Part VI also permits for the use of new non-LP marked cables and previously installed cablesprovided the current is limited so that the cables do not overheat.

Ampacity values in Table 840.160(a) were derived based on review of Reference Data for Engineers:Radio, Electronics, Computer and Communications, 7th Ed., and NFPA 79, 12.5.1. Adjustments weremade considering Article 522 of the NEC, and other sources

CMP-16 chooses not the include Information Note No. 2 with reference to http://wiki.xtronics.com/index.php/Wire-Gauge_Ampacity as provided by the submitter. Data does not necessarily add valueto the data in Table 840.160(A). Changes made by CMP-16 meet the intent of the submitter.

Affirmative with Comment

Ivans, Randolph J.

We agree with the addition of this new section in Article 840. However, the structure and wording of 840.160 areconfusing. For example, except for the temperature adjustment information, “(D)” is just a repetition of “(A)” and“(B)”. “(B)” says you have to meet current limits then “(C)” says you don’t. In addition, there needs to be currentlimitations included for the type –LP cables even though they may be higher than permitted by Table 840.160(A).Finally, since Chapter 9, Table 11(B) has limitations for maximum power and current and rated power and current,these need to be identified in the text. Suggested revisions are as follows: 840.160 Powering Circuits.Communications cables, in addition to carrying the communications circuit, shall also be permitted to carry circuitsfor powering communications equipment. The communications cables and the powering circuits shall comply with840.160(A), (B) and (C). (A) Maximum Power and Current Limitations. The maximum power (VAmax) and current(Imax) limitations of the powering circuits shall comply with the Class 2 requirements of Table 11(B) in Chapter 9for voltage sources up to 60 V dc. (B) Rated Power. The maximum rated power of the powering circuit shallcomply with the Class 2 requirements of Table 11(B) in Chapter 9 for voltage sources up to 60 V dc. InformationalNote: The 100 VA (100 W) power source maximum nameplate rating in Chapter 9, Table 11(B) is the same as themaximum power rating for network-powered broadband communications systems in Table 830.15, thecommunications industry standard in ATIS-0600337.2010 and UL 60950-21. (C) Rated Current. The maximumrated current of the power source that may be carried by each communications cable conductor shall conform to840.160(C)(1) or 840.160(C)(2). Informational Note: The ampacity of the small wire gauges used incommunications cables are not included in the ampacity tables in Article 310. (1) Installations of New Cables. Newcables type CMP-LP, CMR-LP or CM-LP, as applicable, installed for carrying both communications and power,shall be supplied by a power source with a maximum current rating that is less than the maximum adjustedampacity of the conductors in Table 840.160(XX). For ambient temperatures other that 30°C (86°F) ampacity shallbe permitted to be adjusted per Table 310.15(B)(2)(a). (2) New and Existing non-LP Cables. New and existingcables without the “LP” marking shall be permitted to connect to communications equipment that suppliescommunications and power provided that the maximum current supplied by the power source is less than theadjusted ampacity of conductors in Table 840.160(A). For ambient temperatures other that 30°C (86°F) ampacityshall be permitted to be adjusted per Table 310.15(B)(2)(a).

McCoy, William J.

Table 840.160(A) is missing from the FR. Also, The ampacities for other than 30?C temperature ratings need tobe addressed and requires additional research. Definition of separation and wiring methods must be addressed aspart of the ratings. Applications will be such that temperatures other than 30 degrees C will be encountered.

Negative with Comment

Prezioso, Luigi G.

While there is a potential issue with the overheating of cables that are powering network devices, there was noevidence of an existing safety hazard presented, and therefore no justification for an entirely new cable listing. Thedevelopment of the requirements is not based on solid evidence and needs further investigation prior to beingmade part of the Code. The requirement to use the "LP" in new installations "New cables installed for carryingboth communications and power, where the maximum adjusted ampacity of conductors exceed the values inTable 840.160(A), shall be Type CMP-LP, CMR-LP or CM-LP, as applicable." requires the infrastructure designersto determine "the maximum adjusted ampacity of conductors" at the time the infrastructure design is completed.This is potentially years before the network design has been completed and possibly before a new, futurenetworking solution has even been identified.

The term “Exposed” has multiple meanings throughout the NEC: uncovered and capable of being touched bypersons, susceptible to physical damage, e.g., wiring attached to a surface, susceptible to power influences suchas contact or induction, and susceptible to lightning influences, either a direct ‘hit’, induction or ground potentialrise. Hence, the Informational Note provides clarity and should be maintained.

Informational Note No.3 should read “Informational Note No. 3: Paint, plaster, cleaners, abrasives, corrosiveresidues, or other contaminants may result in an undetermined alteration of optical fiber cable properties.”

Ivans, Randolph J.

The revised text “The installation shall also conform with to 300.4(D)and 300.11.” does not align with theCommittee Statement. We agree with the revised text which aligns with 800.24 and 820.24 which also covercircuits that do not present an electrical safety hazard. We do not agree with the committee statement to reference300.4 in its entirety as there is no technical substantiation presented to support the addition of requirements. Itshould be noted that “through (G)” that is now correctly shown stricken was included in the 2014 NEC in error. SeeCorrelating Committee action on Proposals 16-40 and -41, and Comments 16-18, 19, -20, -21 and -23.

McCoy, William J.

Informational Note No. 3 is totally out of place; it is Informational Note No. 3 from the next FR, FR 4519 for770.26. The correct Informational Note No. 3 can be found in FR 4651 for 800.24.


Brunssen, James E.

There is an error in that the FR text does not agree with the Committee Statement regarding 300.4. Further, thereis an error in the NEC 2014 Edition where only 300.4(D) should have been referenced (See CorrelatingCommittee action on Proposals 16-40 and -41, and Comments 16-18, 19, -20, -21 and -23). The reference toSection 300.4 should have been deleted entirely. The requirements of 300.4 are appropriate for power wiring, notoptical fiber cables. Neither a fire nor electrical safety hazard has been identified to justify expanding therequirements of 700.24. Optical fiber cables carry no power and pose neither a fire nor electrical safety hazard.Referencing 300.4 creates a correlation issue with NEC Section 90.1 (Purpose) – “… safeguarding of persons andproperty from hazards arising from the use of electricity”. There is no electricity, hence no electrical hazard.Informational Note No. 3 appears to be in error (looks like it comes from 770.44 [new]). Per Panel Action on PI No.563, Informational Note NO. 3 should address contamination from paints, cleaners, etc. similar to what was donein 800.24, 820.24 and 830.24.

Johnson, Steven C.

I support Mr. Brunssen’s comment: ” The requirements of 300.4 are appropriate for power wiring, not optical fibercables. Neither a fire nor electrical safety hazard has been identified to justify expanding the requirements of


45 of 381 4/16/2015 11:14 AM

700.24. Optical fiber cables carry no power and pose neither a fire nor electrical safety hazard. Referencing 300.4creates a correlation issue with NEC Section 90.1 (Purpose) – “… safeguarding of persons and property fromhazards arising from the use of electricity”. There is no electricity, hence no electrical hazard. “

Moore, Thomas E.

This negative vote is based on the First Draft language including legislative formatting. We support the panelactions of the first draft meeting and not the error in the legislative formatting. The fourth sentence of 770.24contains an error in the legislative formatting and should read “The installation shall conform to 300.4 and 300.11.”The panel meeting action was to reference 300.4 in its entirety which is supported in the panel statement. CMP 16as part of its motion to create a First Revision to 770.24 agreed to expand the protection requirements to includeall of 300.4 not just previous (D) through (G). Optical Fiber Cables are not limited to communications installationsand need protection against physical damage regardless if they can be a shock hazard or not. The term “fiberoptical cables” is used 301 times in the 2014 NEC. Any type of damage to the cable can cause failure to the useand operation of the cable and/or systems they are part of such as failure of a life safety Fire Alarm System. Anerror did NOT exist in the 2014 NEC edition, ROP 16-40 and 16-41 were accepted to include 300.4(A) through (G)not just 300.4(D) this was further supported in comment ROC 16-16 with the following panel statement “The panelreaffirms its original action (at the ROP meeting) to accept Proposal 16-40 and 16-41. The substantiation that fireand shock are only things to consider is incorrect. Fiber optic cables is used for life safety applications such as forfire alarm systems, some building system controls and industrial process controls.”

Prezioso, Luigi G.

There is no valid safety justification for expanding the requirements of 300.4 to 770.24 as optical fiber cablescarry no power. As optical fiber cables carry no power, there is no electrical hazard, and no need for therequirements.

The added text about extending the point of entrance was recommended to be an informational note in PI 1561. Ifthe panel had adopted that recommendation, it would have avoided the confusion of permitting the extension ofthe point of entrance by using RMC or IMC when the point of entrance is already defined as the point emergencefrom RMC or IMC.


Brunssen, James E.

The proposed added text “The point of entrance shall be permitted to be extended from the penetration of theexternal wall or floor slab to the point of emergence from the rigid metal conduit (RMC) or intermediate metalconduit (IMC) by continuously enclosing the entrance cables in rigid metal conduit (RMC) or intermediate metalconduit (IMC).” is a cumbersome and run-on sentence that is both confusing and redundant. The definition, “pointof entrance”, currently and adequately defines RMC and IMC as acceptable vehicles establishing the point ofentrance. If the Panel feels it is necessary to further clarify the use of RMC and IMC, greater clarity is provided bya simple Informational Note such as “The point of entrance may be extended further into the building by continuingto enclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).”

Prezioso, Luigi G.

This Section has caused confusion and the proposed added text “The point of entrance shall be permitted to be

extended from the penetration of the external wall or floor slab to the point of emergence from the rigid metalconduit (RMC) or intermediate metal conduit (IMC) by continuously enclosing the entrance cables in rigid metalconduit (RMC) or intermediate metal conduit (IMC).” does little to resolve this confusion. I support including anInformational Note that states “The point of entrance may be extended further into the building by continuing toenclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).”

Section 770.49 is specific to metallic entrance conduit grounding. The only types of metallic entrance conduitpermitted are RMC and IMC. Hence, in this section we are dealing only with RMC and IMC. While it is true that allmetallic conduit should be grounded, such a general statement here may mislead the reader to incorrectlyconclude that other types of metallic conduit may be used as entrance conduit.

Informational Note No. 1 should not be deleted. It is extremely important, from a communications provider point ofview, that the reader and user of the Code be reminded that there are circumstances under which Article 800 doesnot apply. The presence of Informational Note No. 1 will help ensure that AHJs do not erroneously apply therequirements of Article 800 to facilities under the exclusive control of the communications utility.

Dorna, Gerald Lee

We are in agreement with the comments made by Mr. Ivans, Mr. Brunssen & Mr. Prezioso on their ballot thatInformational Note No. 1 should not be deleted.

Ivans, Randolph J.

Informational Note No. 1 should not be deleted. 800.1 Scope states: “This article covers communications circuitsand equipment.” Without an informational pointer to 90.2(B)(4) the reader/user could overlook the fact that somecommunications installations are not covered by the NEC.

The point of entrance shall be permitted to beextended from the penetration of the external wall or floor slab to the point of emergence from the rigidmetal conduit (RMC) or intermediate metal conduit (IMC) by continuously enclosing the entrance cablesin rigid metal conduit (RMC) or intermediate metal conduit (IMC).

Informational Note No. 1: Splice cases or terminal boxes, both metallic and plastic types, aretypically used as enclosures for splicing or terminating telephone cables.

Informational Note No. 2: This section limits the length of unlisted outside plant cable to 15 m (50ft), while 800.90(B) requires that the primary protector be located as close as practicable to thepoint at which the cable enters the building. Therefore, in installations requiring a primary protector,the outside plant cable may not be permitted to extend 15 m (50 ft) into the building if it ispracticable to place the primary protector closer than 15 m (50 ft) to the point of entrance.

See my affirmative comment on FR 4521 for 770.48. I have copied that comment below: The added text aboutextending the point of entrance was recommended to be an informational note in PI 1561. If the panel hadadopted that recommendation, it would have avoided the confusion of permitting the extension of the point ofentrance by using RMC or IMC when the point of entrance is already defined as the point emergence from RMCor IMC.


Brunssen, James E.

The proposed added text “The point of entrance shall be permitted to be extended from the penetration of theexternal wall or floor slab to the point of emergence from the rigid metal conduit (RMC) or intermediate metalconduit (IMC) by continuously enclosing the entrance cables in rigid metal conduit (RMC) or intermediate metalconduit (IMC).” is a cumbersome, run-on sentence that is both confusing and redundant. The definition, “point ofentrance”, currently and adequately defines RMC and IMC as acceptable vehicles establishing the point ofentrance. If the Panel feels it is necessary to further clarify the use of RMC and IMC, greater clarity is provided bya simple Informational Note such as “The point of entrance may be extended further into the building by continuingto enclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).” ).” Further, the FRdoes not agree with the Committee Statement. There is no text providing clarification that rigid polyvinyl chlorideconduit and electrical metallic tubing containing unlisted outside plant cable are not permitted to be installed inrisers, air ducts or plenums.

Prezioso, Luigi G.

This Section has caused confusion and the proposed added text “The point of entrance shall be permitted to beextended from the penetration of the external wall or floor slab to the point of emergence from the rigid metalconduit (RMC) or intermediate metal conduit (IMC) by continuously enclosing the entrance cables in rigid metalconduit (RMC) or intermediate metal conduit (IMC).” does little to resolve this confusion. I support including anInformational Note that states “The point of entrance may be extended further into the building by continuing toenclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).”

(A) Application.

A listed primary protector shall be provided on each circuit run partly or entirely in aerial wire or aerialcable not confined within a block. Also, a listed primary protector shall be provided on each circuit, aerialor underground, located within the block containing the building served so as to be exposed to accidentalcontact with electric light or power conductors operating at over 300 volts to ground. In addition, wherethere exists a lightning exposure, each interbuilding circuit on a premises shall be protected by a listedprimary protector at each end of the interbuilding circuit. Installation of primary protectors shall alsocomply with 110.3(B).

Informational Note No. 1: On a circuit not exposed to accidental contact with power conductors,providing a listed primary protector in accordance with this article helps protect against otherhazards, such as lightning and above-normal voltages induced by fault currents on power circuits inproximity to the communications circuit.

Informational Note No. 2: Interbuilding circuits are considered to have a lightning exposure unlessone or more of the following conditions exist:

(1) Circuits in large metropolitan areas where buildings are close together and sufficiently high tointercept lightning.

(2) Interbuilding cable runs of 42 m (140 ft) or less, directly buried or in underground conduit,where a continuous metallic cable shield or a continuous metallic conduit containing the cableis connected to each building grounding electrode system.

(3) Areas having an average of five or fewer thunderstorm days per year and earth resistivity ofless than 100 ohm-meters. Such areas are found along the Pacific coast.

Informational Note: For information on lightning protection systems, see NFPA 780 - 2014,Standard for the Installation of Lightning Protection Systems.

The recommendation by the submitter of PI-181 to insert the word “listed” in order to clarify that theonly types of communications raceways and cable routing assemblies permitted are listed ones hasnot been incorporated into the first revision text of 800.113(E) because it would be redundant; thefirst revision text of 800.110(A)(2) requires that communications raceways be listed and the firstrevision text of 800.110(C) requires cable routing assemblies be listed.


The parenthetical “innerduct” clarifies that raceways identified in a., b. and c. are being used asinnerduct.

This revision satisfies Comment 16-58 reported as “Hold” by the NEC Correlating Committee duringthe 2014 NEC revision cycle.

Committee Statement

CommitteeStatement:

The revisions to Table 800.154(a) correlate the table with the revisions to 800.113. The word “type” isadded to the second sentence of the note following the table for consistency. The final sentence ofTable 800.154(a) Informational Note No. 1 is deleted as it is contrary to the definition in 800.2, "Pointof Entrance" and may lead to confusion. Section 800.2 defines "Point of Entrance.” The final sentenceof Table 800.154(a) IN No. 1 states that communications entrance cables must emerge from RMC or


169 of 381 4/16/2015 11:14 AM

IMC to be considered to be in the building. It excludes communications cables emerging from anexternal wall or from a concrete floor slab and hence is confusing, misleading and does not correlatewith the definition in 800.2. It is sufficient that IN No. 1 direct the reader to the definition in 800.2 thusavoiding potential confusion. CMP-16 revises IN No. 2 for consistency with 800.113. CMP-16 deletesInformational Note 3 as it is does not add clarity to the user.

The revised text introduces the use of or under floor covering, modular tiles and planks other thancarpet.

CMP-16 edits 800.154(b) to include “communications” in the title. “Communications raceway” wasalso added to a note to the bottom of the table to cover editorial changes and clarity. CMP-16800.154(c) addressed addition of “cable routing assembly” as these are now included in the article.

The sentence “The definition of Point of Entrance is in 800.2.”of IN No. 1 to Table 800.154(a) is incorrectly struckout.

Informational Note: One method of defining resistant to the spread of fire is that the cables do notspread fire to the top of the tray in the “UL Flame Exposure, Vertical Flame Tray Test” in ANSI/UL1685-2010, Standard for Safety for Vertical-Tray Fire-Propagation and Smoke-Release Test forElectrical and Optical-Fiber Cables. The smoke measurements in the test method are notapplicable.

Another method of defining resistant to the spread of fire is for the damage (char length) not toexceed 1.5 m (4 ft 11 in.) when performing the CSA “Vertical Flame Test — Cables in Cable Trays,”as described in CSA C22.2 No. 0.3-M-2001 0.3-09 , Test Methods for Electrical Wires and Cables.

Part of the panel statement was written stating that "UL has revised and reissued UL 2024 on January 9, 2015."This revised UL 2024 was not available for public review during 2017 NEC PI stage. We believe that NEC TCCshould review this FR and see if the reference to the 2015 UL 2024 should be permitted. We are uncertain if theUL 2024 listed cable routing assemblies to be used in plenum applications. This FR has a domino effect on a lot ofFR's regarding UL 2024 plenum rated listing requirement of cable routing assemblies .

Unlisted outside plant coaxial cables shall be permitted to be installed in building spaces other than risers,ducts used for environmental air, plenums used for environmental air, and other spaces used forenvironmental air, where the length of the cable within the building, measured from its point of entrance,does not exceed 15 m (50 ft) and the cable enters the building from the outside and is terminated at agrounding block. The point of entrance shall be permitted to be extended from the penetration of theexternal wall or floor slab to the point of emergence from the rigid metal conduit (RMC) or intermediatemetal conduit (IMC) by continuously enclosing the entrance cables in rigid metal conduit (RMC) orintermediate metal conduit (IMC).

See my affirmative comment on FR 4521 for 770.48. Which I have copied here: The added text about extendingthe point of entrance was recommended to be an informational note in PI 1561. If the panel had adopted thatrecommendation, it would have avoided the confusion of permitting the extension of the point of entrance by usingRMC or IMC when the point of entrance is already defined as the point emergence from RMC or IMC.


Brunssen, James E.

The proposed added text “The point of entrance shall be permitted to be extended from the penetration of theexternal wall or floor slab to the point of emergence from the rigid metal conduit (RMC) or intermediate metalconduit (IMC) by continuously enclosing the entrance cables in rigid metal conduit (RMC) or intermediate metalconduit (IMC).” is a cumbersome, run-on sentence that is both confusing and redundant. The definition, “point ofentrance”, currently and adequately defines RMC and IMC as acceptable vehicles establishing the point ofentrance. If the Panel feels it is necessary to further clarify the use of RMC and IMC, greater clarity is provided bya simple Informational Note such as “The point of entrance may be extended further into the building by continuingto enclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).”

Prezioso, Luigi G.

This Section has caused confusion and the proposed added text “The point of entrance shall be permitted to beextended from the penetration of the external wall or floor slab to the point of emergence from the rigid metalconduit (RMC) or intermediate metal conduit (IMC) by continuously enclosing the entrance cables in rigid metalconduit (RMC) or intermediate metal conduit (IMC).” does little to resolve this confusion. I support including anInformational Note that states “The point of entrance may be extended further into the building by continuing toenclose the entrance cable in rigid metal conduit (RMC) or intermediate metal conduit (IMC).”

The shield of the coaxial cable shall be bonded or grounded as specified in 820.100(A) through (D E ).

Exception: For communications systems using coaxial cable confined within thepremises and completely contained within the building (i.e., they do not exit the building) or the exteriorzone of protection defined by a 46 m (150 ft) radius rolling sphere and isolated from outside cable plant,the shield shall be permitted to be grounded by a connection to an equipment grounding conductor asdescribed in 250.118. Connecting to an equipment grounding conductor through a grounded receptacleusing a dedicated bonding jumper and a permanently connected listed device shall be permitted. Use ofa cord and plug for the connection to an equipment grounding conductor shall not be permitted.

Committee Statement

CommitteeStatement:

The revisions to Table 820.154(a) correlate the table with the revisions to 820.113. The word “type” isadded to the second sentence of the note following the table for consistency. The final sentence ofTable 820.154(a) Informational Note No. 1 is deleted as it is contrary to the definition in 820.2, "Pointof Entrance" and may lead to confusion. Section 820.2 defines "Point of Entrance.” The final sentenceof Table 820.154(a) IN No. 1 states that coaxial entrance cables must emerge from RMC or IMC to beconsidered to be in the building. It excludes coaxial cables emerging from an external wall or from aconcrete floor slab and hence is confusing, misleading and does not correlate with the definition in820.2. It is sufficient that IN No. 1 direct the reader to the definition in 820.2 thus avoiding potentialconfusion. CMP-16 revises IN No. 2 for consistency with 820.113. CMP-16 deletes Informational Note3 as it is does not add clarity to the user.

820.179 Coaxial Cables.

Cables shall be listed in accordance with 820.179(A) through (D) and marked in accordance with Table820.179. The cable voltage rating shall not be marked on the cable. Coaxial cables shall have atemperature rating of not less than 60°C (140°F). The temperature rating shall be marked on the jacket ofcoaxial cables that have a temperature rating exceeding 60°C (140°F).

Informational Note: Voltage markings on cables could be misinterpreted to suggest that the cablesmay be suitable for Class 1, electric light, and power applications.

Exception: Voltage markings shall be permitted where the cable has multiple listings and voltagemarking is required for one or more of the listings.

(A) Type CATVP.

Type CATVP community antenna television plenum coaxial cables shall be listed as being suitable for usein ducts, plenums, and other spaces used for environmental air and shall also be listed as havingadequate fire-resistant and low smoke-producing characteristics.

Informational Note: One method of defining a cable that is low smoke-producing cable andfire-resistant cable is that the cable exhibits a maximum peak optical density of 0.50 or less, anaverage optical density of 0.15 or less, and a maximum flame spread distance of 1.52 m (5 ft) orless when tested in accordance with NFPA 262-2011 2015 , Standard Method of Test for FlameTravel and Smoke of Wires and Cables for Use in Air-Handling Spaces.

(B) Type CATVR.

Type CATVR community antenna television riser coaxial cables shall be listed as being suitable for use ina vertical run in a shaft or from floor to floor and shall also be listed as having fire-resistant characteristicscapable of preventing the carrying of fire from floor to floor.

Informational Note: One method of defining fire-resistant characteristics capable of preventing thecarrying of fire from floor to floor is that the cables pass the requirements of ANSI/UL 1666-2011,Standard Test for Flame Propagation Height of Electrical and Optical-Fiber Cable InstalledVertically in Shafts.

(C) Type CATV.

Type CATV community antenna television coaxial cables shall be listed as being suitable for general-purpose CATV use, with the exception of risers and plenums, and shall also be listed as being resistant tothe spread of fire.

Informational Note: One method of defining resistant to the spread of fire is that the cables do notspread fire to the top of the tray in the “UL Flame Exposure, Vertical Tray Flame Test” in ANSI/UL1685-2010, Standard for Safety for Vertical-Tray Fire-Propagation and Smoke-Release Test forElectrical and Optical-Fiber Cables. The smoke measurements in the test method are notapplicable.

Another method of defining resistant to the spread of fire is for the damage (char length) not toexceed 1.5 m (4 ft 11 in.) when performing the CSA “Vertical Flame Test — Cables in Cable Trays,”as described in CSA C22.2 No. 0.3-M-2001 0.3-09 , Test Methods for Electrical Wires and Cables.


261 of 381 4/16/2015 11:14 AM

(D) Type CATVX.

Type CATVX limited-use community antenna television coaxial cables shall be listed as being suitable foruse in dwellings and for use in raceways and shall also be listed as being resistant to flame spread.

Informational Note: One method of determining that cable is resistant to flame spread is by testingthe cable to the VW-1 (vertical-wire) flame test in ANSI/UL 1581-2011, Reference Standard forElectrical Wires, Cables and Flexible Cords.

830.1 Scope.

This article covers network-powered broadband communications systems that provide any combination ofvoice, audio, video, data, and interactive services through a network interface unit.

Informational Note: A typical basic system configuration includes a cable supplying power andbroadband signal to a network interface unit that converts the broadband signal to the componentsignals. Typical cables are coaxial cable with both broadband signal and power on the centerconductor, composite metallic cable with a coaxial member(s) or twisted pair members for thebroadband signal and a twisted pair members for power, and composite optical fiber cable with apair of conductors for power. Larger systems may also include network components such asamplifiers that require network power.

Informational Note No. 2: See 90.2(B)(4) for installations of broadband communications systemsthat are not covered.

The term “Exposed” has multiple meanings throughout the NEC: uncovered and capable of being touched bypersons, susceptible to physical damage, e.g., wiring attached to a surface, susceptible to power influences suchas contact or induction, and susceptible to lightning influences, either a direct ‘hit’, induction or ground potentialrise. Hence, the Informational Note provides clarity and should be maintained.

The revisions to Table 830.154(a) correlate the table with the revisions to 830.113. The word “type” isadded to the second sentence of the note following the table for consistency. The final sentence ofTable 830.154(a) Informational Note No. 1 is deleted as it is contrary to the definition in 830.2, "Pointof Entrance" and may lead to confusion. Section 830.2 defines "Point of Entrance.” The final sentenceof Table 830.154(a) IN No. 1 states that network-powered broadband communications entrancecables must emerge from RMC or IMC to be considered to be in the building. It excludes network-powered broadband communications cables emerging from an external wall or from a concrete floorslab and hence is confusing, misleading and does not correlate with the definition in 830.2. It issufficient that IN No. 1 direct the reader to the definition in 830.2 thus avoiding potential confusion.CMP-16 revises IN No. 2 for consistency with 830.113. CMP-16 deletes Informational Note 3 as it isdoes not add clarity to the user.

840.1 Scope.

This article covers premises-powered optical fiber-based broadband communications systems thatprovide any combination of voice, video, data, and interactive services through an optical networkterminal (ONT) .

Informational Note No. 1: A typical basic system configuration consists of an optical fiber, twistedpair, or coaxial cable to the premises (FTTP) supplying a broadband signal to an ONTa networkterminal that converts the broadband optical signal into component electrical signals, such astraditional telephone, video, high-speed internet Internet , and interactive services. Powering of theONT for the network terminal and network devices is typically accomplished through an ONTapremises power supply unit (OPSU) and that might be built into the network terminal or providedas a separate unit. In order to provide communications in the event of a power interruption, abattery backup unit (BBU) that derive their power input from the available ac at the premises. Theoptical fiber cable is unpowered and may be nonconductive or conductive. or an uninterruptiblepower supply (UPS) is typically part of the powering system.

Informational Note No. 2: See 90.2(B)(4) for installations of premises-powered broadbandcommunications systems that are not covered in this article.

Committee Statement

CommitteeStatement:

CMP-16 makes changes to the Scope. CMP-16 realizes that Scope is under the purview of the CC.

The revisions include the following:

1) Expand the scope and coverage of Article 840 to match the title “Premises-Powered BroadbandCommunications Systems”.

2) Introduce powering systems such as Power over Ethernet (PoE) into Chapter 8 in order to providesafe installation rules for premises-powered communications applications.

Deployments of systems such as PoE are wide-spread methods of providing premises power tocommunications equipment. Compliance with the industry specifications for these systems is notmandatory; some installations comply while others do not. Each time the standards are revised, theyenable higher power levels to the powered devices, thereby leading to safety concerns including, butnot limited to, the excess heating of cables. Exceeding the temperature rating of a cable will lead tolong term degradation of the cable. Acceptance of this PI and its companion PIs will provide for thesafe installation of premises-powered communications systems. The proposed limits on PoE powerare consistent with communications industry standards as well as the long-established limits for Class2 dc power sources.

Many premised-powered broadband communications systems are provided by the local cable TVfranchise over coaxial cable. Their network terminal is commonly called a modem. Other premises-powered broadband communications systems are offered by the local “telephone company”. Some

The recommended text of the informationalnote simply uses the term “network terminal” to describe the terminal regardless of the inputtransmission medium.

Section 800.48 does not address communications wires. Hence, stating in 840.48(B) that “Installations of unlistedcommunications wires and unlisted multipair communications cables entering buildings shall comply with 800.48”is misleading. Section 800.48 should be revised to correlate with 840.48(B) if the Panel is concerned about theflammability of unlisted communications wires entering buildings.

Committee Statement

CommitteeStatement:

The expanded coverage of Article 840 to cover PoE requires that the article recognize twistedpair-based and coaxial cable-based systems in addition to optical fiber-based systems. Instead of“optical network terminal” which applies only to optical fiber-based systems, the recommended textsimply calls the interface a “network terminal”.

Revised Informational Note No. 1 updates the list of referenced UL standards.

New paragraph (H) is added to cover listing requirements for these power sources.

Listing requirements were developed considering worst-case installation conditions. Similar toCMP-CI, CMR-CI and CM-CI cables, the new cables are marked Types CMP-LP, CMR-LP andCM-LP.

Premises-powered installations especially at multi-dwelling units include more equipment thanONTs, such as, optical cross-connects, slack storage units, and other assemblies which need to belisted for the application. Adding (I) Accessory Equipment addresses this issue.

The words “See” and “that” are superfluous. The informational note should read: “Informational Note: InformationalNote Figure 800(a) and Informational Note Figure 800(b) illustrate the application of bonding and grounding electrodeconductors in communications installations." The caption for Informational Note Figure 800(b) is correct in the FR, butis incorrect as shown in the TeraView version of the document. It should state: “Informational Note Figure 800(b)Illustration of Grounding Electrode Conductor in a Communications Installation.”
