Chairman’s Report for NEC CMP 1

______________________________________________

1) NEC Second Draft Meeting: November 12‐13, 2015

2) A list of members and guests in attendance is attached. 3) The following guests addressed the panel:

Jim Dollard, Arc‐flash hazard label for service equipment, 13 minute presentation and 1 minute Q&A session Larry Ayer, Arc‐flash hazard label for service equipment, 8 minute presentation and 6 minute Q&A session

4) Number of Public Comments acted upon: 78 5) Number of Second Revisions created: 22 6) List any Task Groups appointed to work subsequent to the Second Draft Meeting, along with the names of members of the Task Group(s): Task Group 1: Palmer Hickman, Chair; Roland Deike, Ernie Gallo, Paul Sood, and Ark Tsisserev. TG1 addressed, Article 90, Sections 110.2 through 110.12, and Annex A (16 PCs). Task Group 2: David Hittinger, Chair; Mike Johnston, Joe Marquardt, Mike Stone, Jim Pierce, and Frank Tyler. TG2 addressed Global Comments and Article 100 (15 PCs). Task Group 3: Bill Fiske, Chair; Louis Barrios, Mark Christian, Don Iverson, Gary Jones, and Harry Sassaman. TG3 addressed Section 110.26 through the end of Article 110 (19 PCs). Task Group 4: Dirk Mueller, Chair; Mike Anthony, Jim Brunssen, Don Offerdahl, and Kent Sayler. TG4 addressed Sections 110.14 through 110.25 (19 PCs). Arc Flash Label TG: Mike Anthony, Mark Christian, Palmer Hickman, Don Iverson, and Joe Marquardt developed a proposed Second Revision and Panel Statement for some PCs involving Section 110.16(B).


7) List any request contained in a Responses or Statement that require NEC Correlating Committee attention: PC 576 addressed relocation of all definitions to Article 100. NFPA Staff discussed the document format and consideration being given to identifying in each definition the particular CMP responsible for that content; it was indicated that the content and formatting would be an NFPA staff issue rather than CMP 1 driven. CMP 1 notes that the NEC Style Manual Sections 2.2.2.1 and 2.2.2.2 may need to be revised depending on the final decision. PC 1732 addressed the definition of Building in Article 100. The PC was held. CMP 1 requests that the Correlating Committee consider the need for a Task Group to address this definition. PCs 531, 532, and 976 involved the term “listed and labeled”. The panel held these comments. CMP 1 recognizes that the Correlating Committee will have this issue addressed through a Task Group. 8) The following Public Comments or Second Revisions should be referred to another panel for information or correlation: PC 1618 sought to add a new definition of “Dormitory” to Article 100. The PC was held. CMP 1 understands that the term is only used in the 2014 NEC in Article 210, but there is consideration in CMP 18 to add another use of the term in the 2017 NEC. For this reason, CMP 1 requested that this PC be referred to CMP 2 and CMP 18. 9) There are no Public Comments or Second Revisions that should be referred to the Toxicity Advisory Committee.

10) There are no Public Comments or Second Revisions related to combustibles in plenums or other air handling spaces.

11) There are no new requests for the NFPA Research Foundation at this time.

12) Requests for information or assistance from the NEC Correlating Committee: A number of PCs including PCs 38 and 495 addressed the designation of American National Standards. The various PCs approached the issue in different ways relative to including “ANSI” as part of the standard designation and the name of the standard development organization within the designation. Consideration by the Correlating Committee of a consistent approach is requested. 13) Additional information:


Some of the PCs involving the content of Section 110.16(B) involved issues about the relationship between the scope of the NEC and the scope of NFPA 70E. This issue had been raised in the CMP 1 First Draft meeting report, and CMP 1 heard during the Second Draft meeting from Correlating Committee members that the CC had concluded that the scope issue neither required nor prohibited CMP 1 from taking any specific action on the PCs involving Section 110.16(B). The Second Revision that was developed was intentionally crafted to focus on NEC content on installation issues that can enable safe work practices. Overall some good progress was made on continuing the transition to the new process and systems. However, as discussed with NFPA staff at the meeting, there are several issues that generated some frustration and inefficiencies for the Panel members. First, when multiple PCs affected a single Section, the methods for dealing with each Comment most effectively were a challenge. Depending on the actions for each Comment, the editorial/document hierarchy, and the way the PC was entered, there was a critical strategy that was required to most effectively manage the business of the Panel. This had not been clear to many of the members, and thus the Task Group work products were not developed with that strategy ‐ causing rework in the meeting. Additional measures would be helpful going forward to make the work more effective and efficient. This may include additional training, work tools, direct support from NFPA staff at the Task Group stage, or other ideas. Second, there were a number of issues where the Comments reflected changes that were not intended or in some cases according to Panel members not entered the way they appeared. This included additional text being shown as struck out when that was clearly not the intention of the submitter. It did cause some inefficiency, especially when coupled with the more restrictive ways of dealing with multiple PCs for a given segment of text outlined above. Continued efforts to resolve this issue would be beneficial. Respectfully submitted,

Chairman’s Report for the NEC CMP 2 1. List date(s) and location of meeting: CMP-2 full panel met from Monday November 9 to Wednesday November 11, 2015 and TG 2 met on Sunday November 8, 2015. 2. A list of members and guests in attendance is attached. 3. List names of guests addressing the Panel, the subject of their address, and the length of time they spoke: 1. Larry Ayer – Addressed the CMP on Comment No. regarding Table 220.12.

Mr. Ayer spoke for 12 minutes and there were no questions from the Panel members.

2. Kevin Lipett – Addressed the CMP on Comment No. regarding 210.12. Mr.

Lipett spoke for 10 minutes and there no questions from the Panel members. 3. Robert Simon – Addressed the CMP on Comment No. regarding 210.12. Mr.

Simon spoke for 8 minutes and was an additional 6 minutes of questions from the Panel members.

4. Number of Public Comments acted upon:__107________ 5. Number of Second Revisions created:__27_ __ 6. List any Task Groups appointed to work subsequent to the Second Draft Meeting, along with the names of members of the Task Group(s): N/A 7. List any request contained in a Panel Statement that requires NEC Correlating Committee attention: N/A 8. List any Public Comments or Second Revisions that, in your opinion, need to be referred to another TC for information or correlation: N/A 9. List any Public Comments or Second Revisions that should be referred to the Toxicity Advisory Committee: N/A 10. List all Public Comments or Second Revisions related to combustibles in plenums or other air handling spaces: N/A


11. Identify any issues that should be brought to the attention of the NFPA Research Foundation for their input and assistance: In regards to 210.8, CMP 2 members requested the NFPA Research Foundation consider establishing a working group to identify the number of shock incidents concerning appliances. The two categories suggested were (1) the number of shock incidents that occur at the outlets for cord and plug connected appliances and (2) the number of shock incidents that occur at the appliance for hard wired (not cord and plug connected) appliances. 12. List any general requests for information or assistance from the NEC Correlating Committee: If SR 315 passes ballot I ask the Correlating Committee review the matter and consider my negative ballot comments. During the First Draft stage a task group was established, that included a member from CMP 17, to consider and, if approved, to coordinate the action to move the GFCI requirement for specific appliances to 422.5 where the GFCI requirements for other specific appliances were located. CMP 2 also made further revisions to the scope of Article 210 to clarify the article contained general the general requirements for branch circuits and that requirements for specific equipment branch circuits were located in the article coving the specific equipment. For example; in addition to moving the specific equipment, dishwashers and boat hoists to Article 422, the branch circuit requirements for electric vehicle charging were relocated to Article 625. CMP 2 voted to relocate the GFCI requirements for Boat Hoists and Dishwashers to Article 422 where all other similar requirements were already located. A minimal amount of Comments were received to bring dishwashers and boat hoists back to Article 210. Unfortunately one passed the Second Draft meeting by a narrow margin, but nevertheless it passed. Comments submitted to Panel 17 to delete boat hoists and dishwashers from 422.5 were rejected by Panel 17. If the requirements end up in both articles there will be conflicts between the two articles. The NEC CC had no negative comments during the First Draft stage regarding the relocation of specific requirements or the revisions recommended revisions to 210.1 to clarify that Article 210 only contains general purpose branch circuit requirements and that specific equipment branch circuit requirements are located in the article covering the specific equipment. I respectively ask the NEC CC members to consider supporting the First Draft meeting actions. 13. Provide any additional information that you feel would be helpful to the NEC Correlating Committee, staff, or to the process in general: N/A

11) Identify any issues that should be brought to the attention of the NFPA Research Foundation for their input and assistance: None 12) List any general requests for information or assistance from the NEC Correlating Committee: In reviewing FR 1024 referred by the CC, the TC found that terminology related to grounding and bonding in Article 690 is often not used in accordance with the definitions. In the 2014 revision cycle the CC appointed a joint task group consisting of members of Panel 4 and Panel 5 to discuss grounding issues in Article 690. The recommendations of the Task Group were not consistently followed. Panel 5 believes that with few exceptions the provisions of Article 250 are adequate to address the installation of PV systems and asks the CC to assist in bringing consistency in the use and application of terms and installation practices related to grounding and bonding of solar photovoltaic systems. 13) Provide any additional information that you feel would be helpful to the NEC Correlating Committee, staff, or to the process in general: At the end of the meeting, some members of Panel 5 asked for a straw poll regarding adding labeling requirements for listed products throughout the code to provide information to the CC about their views. The result of the informal poll was a vote of 9-7 in favor of requiring labeling as a general rule.


Some members of Panel 5 asked that their difficulties cutting and pasting from the First Draft Report be reported to NFPA. Our limited testing revealed that TerraView does not work the same way on different systems running the same version of Firefox so that some members were able to cut and paste from the First draft Report and others were not. The chair was asked to report this to NFPA. The chair wishes to call attention to the lack of attendance of committee member Fred Song who has attended one meeting in the two revision cycles he has been a member. The chair has received no communications from this member regarding his lack of attendance. Finally, the chair and members of the committee wish to commend Barry Chase on his outstanding work as our staff liaison. His ability to navigate between TerraView and Word, as well his general understanding of the use of the Windows OS, were a refreshing change from the past. He was able to quickly catch the drift of the conversation and translate it into draft panel statements or code text for our review which greatly facilitated our rapid progress through the work. He handled the capriciousness of the committee with aplomb and good humor and was a pleasure to work with.

NEC CMP 17 Chairman’s Report

1) NEC SD Meeting: Task Group Meeting on November 1, 2015. Committee Meeting November 2-3, 2015.

2) A list of members and guests in attendance is attached. See roster kept during meeting.

3) List names of guests addressing the Panel, the subject of their address, and the length

of time they spoke: Amy Cronin and Michael Fountain; Topic PC 662 & 663; Time 15 minutes. 4) Number of Public Comments acted upon: 53 5) Number of Second Revisions created: 30 6) List any Task Groups appointed to work subsequent to the Second Draft Meeting, along with the names of members of the Task Group(s): Three TG’s were utilized during the 2017 process. Those TG’s have been maintained to begin work on the 2020 NEC cycle. TG-1 is Chaired by Tom Blewitt. Responsible for Article 422. TG-2 is chaired by Mike Querry. Responsible for Heating Equipment Articles. TG-3 is chaired by Randy Hunter. Responsible for Articles 680 & 682.

7) List any request contained in a Responses or Statement that require NEC Correlating Committee attention: See Panel statement on SR 4806

8) List any Public Comments or Second Revisions, in your opinion, that needs to be referred to another TC for information or correlation: NA


9) List any Public Comments or Second Revisions that should be referred to the Toxicity Advisory Committee: NA

10) List all Public Comments and Second Revisions related to combustibles in plenums or other air handling spaces: NA

11) Identify any issues that should be brought to the attention of the NFPA Research Foundation for their input and assistance: Need for Pool Bonding project remains.

12) List any general requests for information or assistance from the NEC Correlating Committee: Recommend a correlation effort for overlapping scope and requirements between Article 682 and Articles 553 & 555. A joint TG of CMP-17 and CMP-19 would be useful. 13) Provide any additional information that you feel would be helpful to the NEC Correlating Committee, staff, or to the process in general: CC has appointed TG to address the “listing and labeling” issue. CMP-17 acted on that issue on PC’s 1250, 1251, 1252, 1302, 1303, 1305, 1308, 1309, 1310, 1311, and 1313. That resulted in revisions in SR 4802, 4808, 4814, 4815, 4816, 4818, 4819, 4820, 4821, 4822, 4823, 4824, 4825, 4826, 4827, and 4830. CMP-17 members realized during ballot stage the current text in 680.23 (F) (1) does not correlate with other Article 680 text for low voltage pool lights. Other locations evolved from “transformers” to “transformers and power supplies” because of current technology. This section was previously missed and could be correlated if possible. CMP-17 members also discovered a copy/paste error in FR 4841 in 425.6. This text is currently included in 425.6:


Text in 425.6 should likely read:

c. Keith Lofland spoke for 5 minutes explaining the scope and purpose of a CC‐appointed task group evaluating the benefits of a global change to add words related to listed and labeling.

4) Number of Public Comments acted upon: 63 5) Number of Second Revisions created: 28 6) There were no Task Groups appointed to work subsequent to the Second Draft Meeting.

7) There are no requests for that require NEC Correlating Committee attention.

8) There are no comments or SRs that should to be referred to another panel for information or correlation

9) There are no Comments or SRs that should be referred to the Toxicity Advisory Committee.

10) List all PCs or SRs related to combustibles in plenums or other air handling spaces: SR 5124 addresses low voltage wiring in plenums and other spaces.


11) There are no new issues or requests for the NFPA Research Foundation at this time.

12) The panel has no requests for information or assistance from the NEC Correlating Committee at this time.

13) Provide any additional information that you feel would be helpful to the NEC Correlating Committee, staff, or to the process in general: CMP 18 was made aware that the CC had assigned a task group to review and recommend global actions related to adding the words “and labeled” wherever “listed” is used. The panel took a straw poll to determine the opinion of the panel on this issue. The informal vote was overwhelmingly in favor of the action, with only one negative opinion. This information can be passed to the task group. Additionally, CMP 18 recommends that if the direction from the task group is to make the global change, a change must be made to the definitions of both terms, including associated informational notes.

Public Comment No. 1370-NFPA 70-2015 [ Section No. 490.48(B) ]

(B) Diagram.

A permanent, single-line diagram of the switchgear shall be provided in a readily visible location within the same room orenclosed area with the switchgear, and this diagram shall clearly identify interlocks, isolation means, and all possible sources ofvoltage to the installation under normal or emergency conditions and the marking on the switchgear shall cross-reference thediagram.

Exception: Where the equipment consists solely of a single cubicle or metal-enclosed unit substation containing only one setof high-voltage switching devices, diagrams shall not be required.


This Public Comment was developed by a Task Group assigned by the NEC Correlating Committee to: (1) resolve issues with actions taken by Code-making Panels 1 and 8 on proposals and comments in the 2014 NEC cycle relative to changing the voltage threshold in articles under their purview from 600 volts to 1000 volts, (2) address indoor and outdoor electrical substations, and (3) evaluate other higher voltage threshold requirements to be included relative to present trends. Members of the Task Group on Over 600 volts for this Public Comment included: Alan Manche; Donny Cook; Vince Saporita; Paul Barnhart; Eddie Guidry; Alan Peterson; David Kendall; Dave Mercier; Tim Pope; Roger McDaniel and Neil F. LaBrake, Jr..

The Task Group requests that Panel 9 reconsider the previous resolution based on the following additional information.

PI-1541 was resolved with the following panel statement: “Unit substations are understood to be an integrated line up of electrical equipment including a disconnect and optional overcurrent device rated above 1,000 Volts, a transformer with primary windings rated over 1,000 Volts and secondary windings rated less than or equal to or greater than 1,000 Volts, and secondary switchgear rated at the transformer’s secondary voltage. The substation is “unitized” as a single line up of metal enclosures, close coupled, with bus or insulated cable connections that are within the metal enclosures.”

The term “unit substation” is currently found in four sections of the 2014 NEC: 110.31(B)(1), 490.30, 490.48(B)(5)Exception to (1), 490.48(C)Exception. The term “substation” is found in Art. 100 and was revised and moved to Part II (over 1000V) for the 2017 Code cycle.

The terms “substation” and “unit substation” can mean different things to different people depending on the voltage level, application and installation. And, since the term “unit substation” is not defined in Art. 100 or 490, but “substation” is, it is believed that removing the word “unit” would clarify the meaning of this term.

The Task Group requests that CMP 9 consider that product certification encompasses a much broader of the term “unit substation” than the description included in the panel statement in response to PI-1535. Without a separate, clear NEC definition in Article 490, that excludes other equipment which are currently listed by product certification bodies as “unit substations”, use of the term “unit substation” could lead to confusion for the user or inspection authority.

Please consider that UL Information Guide YEFR contains information for unit substations less than 600V. And, UL 1062 is the standard for low voltage unit substations, and contains the following definition: UNIT SUBSTATION - A transformer in combination with primary or secondary overcurrent protective devices or switching devices housed in a single enclosure.

Also consider, UL Information Guide YEFV contains information for unit substations for medium voltage applications. With respect to unit substations over 600V, the YEFV guide information discusses articulated and integral unit substations. The definitions of these two types of unit substations are included in the guide information as follows:Articulated Unit Substations consist of a transformer section(s) together with an input section(s), an output section(s), or both. Transition sections may also be provided. These unit substations are designed, coordinated and assembled as multiple self-enclosed pieces of equipment intended for connection in the field.Integral Unit Substations consist of a transformer section(s) together with an input section(s), an output section(s), or both. Transition sections may also be provided. These unit substations are designed, coordinated and assembled as a single self-enclosed piece of equipment. Sections may be shipped separately.Note that the definition of articulated units does not state that they are a line-up of equipment that is close-coupled, but because it says “designed, coordinated, and assembled…” one might believe this means a line-up. But, conceivably they could be assembled in some other format (such as back to back, with a busway between them, or other configuration).

Integral unit substations are in a single enclosure or a single piece of equipment that may be multiple sections.

In addition to product certification misunderstandings, the term “unit substation” is used widely throughout the petrochemical industry to indicate that the substation is part of a process unit further adding to the confusion as to what the term “unit substation” means in Art. 490.

Removing the word “unit” will result in clearer and more accurate Code language for the user.

Committee Statement

CommitteeAction:

Rejected but held

Resolution: This exception is relying on the aspects of the unit substation to relieve the requirement for a single line diagram. Theintegral line up of metal enclosed equipment with a single primary disconnect, optional overcurrent device, transformer,and switching and overcurrent protection for the secondary side switchgear eliminates the need for interlocked switching,as there is only one primary power source available to the substation. Two unit substations in an electrical room are notthe same as two standalone primary switches, transformers, and secondary switchgear assemblies that are cableconnected. There is no guarantee as to how the stand alone devices are connected. A definition of “unit substation”should be considered in the next code cycle. To this end, CMP 9 has elected to hold this comment which guarantees itsresubmittal in the next cycle. Furthermore, CMP 9 has created a task group to examine this issue.

Public Comment No. 1618-NFPA 70-2015 [ New Definition after Definition: Disconnecting Means. ]

Dormitory. Any occupancy containing a number of beds with common areas and bathroom facilities where people arehoused temporarily.


Requirements for AFCI protection in 210.12 and tamper-resistant receptacles in 406.12 now apply to dormitories. Without an NEC definition of the word “dormitory” installers and inspectors find this section problematic. Perhaps the code-making panel will provide some guidance on whether this requirement should apply to bunkhouses, church camps, summer-camp cabins, lodges, homeless shelters, etc.. which will greatly help with the application of the rule. Accepting the original proposal for the 2014 NEC the panel specifically removed the word "college" from the new AFCI requirement, however many dictionaries specifically reference "colleges" in their definition of the term. The lack of a definition appears to make broad application of those rules appropriate.

300.11 Securing and Supporting.

(A) Secured in Place.

Raceways, cable assemblies, boxes, cabinets, and fittings shall be securely fastened in place.

(B) Wiring Systems Installed Above Suspended Ceilings.

Support wires that do not provide secure support shall not be permitted as the sole support. Support wires and associatedfittings that provide secure support and that are installed in addition to the ceiling grid support wires shall be permitted as thesole support. Where independent support wires are used, they shall be secured at both ends. Cables and raceways shall not besupported by ceiling grids.

(1) Fire-Rated Assemblies.

Wiring located within the cavity of a fire-rated floor–ceiling or roof–ceiling assembly shall not be secured to, or supported by, theceiling assembly, including the ceiling support wires. An independent means of secure support shall be provided and shall bepermitted to be attached to the assembly. Where independent support wires are used, they shall be distinguishable by color,tagging, or other effective means from those that are part of the fire-rated design.

Exception: The ceiling support system shall be permitted to support wiring and equipment that have been tested as part of thefire-rated assembly.

Informational Note: One method of determining fire rating is testing in accordance with ANSI/ASTM E119-2014, Methodfor Fire Tests of Building Construction and Materials.

(2) Non–Fire-Rated Assemblies.

Wiring located within the cavity of a non–fire-rated floor–ceiling or roof–ceiling assembly shall not be secured to, or supportedby, the ceiling assembly, including the ceiling support wires. An independent means of secure support shall be provided andshall be permitted to be attached to the assembly. Where independent support wires are used, they shall be distinguishable bycolor, tagging, or other effective means.

Exception: The ceiling support system shall be permitted to support branch-circuit wiring and associated equipment whereinstalled in accordance with the ceiling system manufacturer’s instructions.

(C) Raceways Used as Means of Support.

Raceways shall be used only as a means of support for other raceways, cables, or nonelectrical equipment under any of thefollowing conditions:

(1) Where the raceway or means of support is identified as a means of support

(2) Where the raceway contains power supply conductors for electrically controlled equipment and is used to support Class 2circuit conductors or cables that are solely for the purpose of connection to the equipment control circuits

(3) Where the raceway is used to support boxes or conduit bodies in accordance with 314.23 or to support luminaires inaccordance with 410.36(E)

(D) Cables Not Used as Means of Support.

Cable wiring methods shall not be used as a means of support for other cables, raceways, or nonelectrical equipment.

(E) Metallic Means of Support Above Egress

Metallic means of support for flexible conduit and conductors shall be used in spaces above egress, which includes doorways,hallways, stairways, corridors, passageways, lobbies, landings, and equivalent spaces.

Informational note: Nonmetallic supports exhibit significant weakening and failure during fires which can affect the safety ofoccupants and emergency personnel entering and exiting buildings due to entanglement in fallen cable.


Emergency responders and building occupant safety is at risk during building fires because people can become entangled and trapped in cabling which has fallen out of molten or failing plastic supports/raceway. Even if people can free themselves from fallen cabling, this takes time which is otherwise needed to exit the building or fulfill the objectives of emergency personnel. The frequency of emergency responders becoming trapped in fallen cabling has become so common that firefighters have created and publicly distributed training videos on how to escape in these situations(http://www.fireengineering.com/topics/m/video/36928837/the-quick-release-method.htm?q=cable+entanglement) [1]. Additionally, the Greater Tucson Fire Foundation raised financial support in 2011 to purchase cable cutters for hundreds of Tucson, Arizona firefighters so that they are equipped to deal with cable entanglement [2].

The ideal scope of this requirement should include all wiring methods which are susceptible to falling during a fire. This includes insulated conductors, flexible metal conduit, and nonmetallic raceways with plastic supports. It should include power conductors, signaling conductors, fire alarm cables, and communications circuits. Although CMP 3 can only address a portion of the relevant scope,

725.24 Mechanical Execution of Work.

Class 1, Class 2, and Class 3 circuits shall be installed in a neat and workmanlike manner. Cables and conductors installedexposed on the surface of ceilings and sidewalls shall be supported by the building structure in such a manner that the cablewill not be damaged by normal building use. Such cables shall be supported by straps, staples, hangers, cable ties, or similarfittings designed and installed so as not to damage the cable. The installation shall also comply with 300.4(D). Metallic means

of support for flexible conduit and conductors shall be used in spaces above egress, which includes doorways, hallways, stairways,

corridors, passageways, lobbies, landings, and equivalent spaces.

Informa onal note: Nonmetallic supports exhibit significant weakening and failure during fires which can affect the safety of occupants

and emergency personnel entering and exi ng buildings due to entanglement in fallen cable.


Emergency responders and building occupant safety is at risk during building fires because people can become entangled and trapped in cabling which hasfallen out of molten or failing plastic supports/raceway. Even if people can free themselves from fallen cabling, this takes time which is otherwise needed toexit the building or fulfill the objectives of emergency personnel.

There have been documented fatalities due to cable entrapment both in the U.S. and England. In Memphis, Tennessee, in 1994, a fireman was entangled incables that had fallen after the nonmetallic raceway collapsed due to the heat (http://www.fireengineering.com/articles/print/volume-148/issue-3/features/tragedy-in-a-residential-high-rise-memphis-tennessee.html [2]).More recently in England two firemen died due in part to being tangled in cabling that had fallen from plastic raceway in the ceiling of a Southampton residential building (http://www.bbc.co.uk/news/uk-england-hampshire-22126431 [3]). An article [4] in Electrical Contracting News identifies another recent incident in which a fireman died in Stevenage, Hertfordshire, after he became entangled in electrical cables which “had fallen after plastic trunking, the only support for the cables, melted and failed.” Article [4] goes on to report that changes are in process to Great Britain’s Wiring Regulations (BS 7671 [5]) to ensure that “wiring systems in any escape route should be supported so that they are not subject to premature failure in a fire.” Revisions have already been made in a standard for fire alarm system cabling, BS 5839-1 [6], to require cable supports/raceway which will not collapse in a fire.While the documented incidents involve firefighters, it is not even known how many building occupants may have died in the past either becoming entangled in fallen cabling, overcome by smoke/heat trying to remove a cabling obstruction, or forced to seek an alternate exit due to a significant amount of cablingobstruction.

NFPA 101 (Life Safety Code, 2012) [7] already addresses the requirement to maintain egress free from obstruction. Sections 7.1.10 and 7.1.10.1 (Means ofEgress Reliability) state,7.1.10.1 General. Means of egress shall be continuously maintained free of all obstructions or impediments to full instant use in case of fire or otheremergency.Sections 12.2.5.4, 12.2.5.4.2, and 12.2.5.4.3 (New Assembly Occupancies) and 13.2.5.4, 13.2.5.4.2, and 13.2.5.4.3 (Existing Assembly Occupancies) alsoemphasize this requirement.12.2.5.4 General Requirements for Access and Egress Routes Within Assembly Areas.12.2.5.4.2 Access and egress routes shall be maintained so that any individual is able to move without undue hindrance, on personal initiative and at any time,from an occupied position to the exits.12.2.5.4.3 Access and egress routes shall be maintained so that crowd management, security, and emergency medical personnel are able to reach anyindividual at any time, without undue hindrance.13.2.5.4 General Requirements for Access and Egress Routes Within Assembly Areas.13.2.5.4.2 Access and egress routes shall be maintained so that any individual is able to move without undue hindrance, on personal initiative and at any time,from an occupied position to the exits.13.2.5.4.3 Access and egress routes shall be maintained so that crowd management, security, and emergency medical personnel are able to reach anyindividual at any time, without undue hindrance

The solution that is easy to understand and enforce is a straightforward requirement regarding the allowable materials of a cable

Informational Note No. 8: Portable or transportable equipment having self-contained power supplies, such as battery-operated equipment, could potentially become an ignition source in hazardous (classified) locations. See ANSI/ISA-12.12.03-2011, Standard for Portable Electronic Products Suitable for Use in Class I and II, Division 2, Class I Zone 2and Class III, Division 1 and 2 Hazardous (Classified) Locations.

Informational Note No. 9: For additional information concerning the installation of equipment utilizing optical emissionstechnology (such as laser equipment) that could potentially become an ignition source in hazardous (classified) locations,see ANSI/ISA-60079-28 (12.21.02)-2013, Explosive Atmospheres — Part 28: Protection of equipment and transmissionsystems using optical radiation.


The Oil and Gas Well Drilling Land Rig Industry faces unique challenges as a result of their need for quick and easy mobility when rigging up and rigging down as the drilling land rig is transported overland between drill sites. In addition, the drilling rigs and the machines on them are subjected to significant movement, shaking, and vibration while drilling. Therefore these conditions require special consideration with regards to the selection and installation of electrical cables in hazardous (classified) locations.

Rigid conduit and Type MC-HL cable are not suitable for the application and in the absence of a consensus standard or recommended practice addressing the unique requirements for installing electric cables in hazardous (classified) locations on land rigs, the Oil and Gas Well Drilling Land Rig Industry has historically looked to consensus standards and practices in the Oil and Gas Well Drilling Offshore Industry for guidance; specifically API RP 14F entitled “Recommended Practice for Design, Installation, and Maintenance of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class 1, Division 1 and Division 2 Locations” and API RP 14FZ entitled “Recommended Practice for Design, Installation, and Maintenance of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class 1, Zone 0, Zone 1, and Zone 2 Locations.”

Adopting wiring methods from API RP 14F and API RP 14FZ, the Oil and Gas Well Drilling Land Rig Industry has historically and for


1074 of 2282 11/19/2015 12:04 PM


over 30 years used IEEE-1580, Type P, marine shipboard cable to cable-up and interconnect the various machines and equipment that make up the drilling land rig. These cables may also be listed as UL-1309 Marine Shipboard Cable. The flexible and rugged IEEE-1580, Type P, marine shipboard cable is highly suitable for the oil and gas well drilling land rig application because of its ability to resist drilling muds that contain various chemicals, abrasives, and petroleum based additives as well as its ability to resist damage from vibration, shaking, and movement that occurs during the drilling process, and the rigors of rig-up and rig-down. They are also highly suited because of their ability to perform in extreme cold weather conditions in that they can pass a -40⁰ C cold bend test and a -35⁰ C cold impact test. In addition to their flexibility and mechanical ruggedness as just described, the IEEE-1580, Type P, marine shipboard cable is rated 600/1000 volts or 2000 volts which makes it suitable for use on both AC and DC powered drilling rigs, has a maximum conductor temperature rating of 110⁰ C, has a flexible tinned-copper stranded conductor that resists oxidation, and passes an IEEE 1202 vertical cable tray flame test. In addition, these flexible tinned-copper conductors are available in sizes like 444 Kcmil, 535 Kcmil, 646 Kcmil, and 777 Kcmil that are currently not recognized in NFPA 70. These cables are also available with a metallic basket-weave braided armor that effectively enhances their durability, provides crush, impact, and cut-through resistance, and is not prone to failure due to fatigue and cracking; properties that are very important in the drilling environment. Collectively, all of these properties and features which are required of both single-conductor and multi-conductor cable used on an oil and gas well drilling land rig are not available on any one cable type included in NFPA 70. More specifically and per API RP 14F and API RP 14FZ; in Class 1, Division 1 and Class 1, Zone 1 hazardous (classified) locations, the Oil and Gas Well Drilling Land Rig Industry uses IEEE-1580, Type P, marine shipboard cable with a metallic basket-weave braided armor and outer polymeric sheath. The metallic basket-weave braided armor with outer polymeric sheath mechanically protects the cable from damage and yet provides the flexibility required for the application. In addition, recommendations in API RP 14F and API RP 14FZ allow the use of unarmored IEEE-1580, Type P, marine shipboard cable in Class 1, Division 2 and Class 1, Zone 2 hazardous areas. Regardless, the specific location on the land rig is given engineering consideration relative to the cable’s vulnerability to mechanical damage. If the location in itself does not provide suitable mechanical protection or the addition of steel guards is not practical for the location, then armored and sheathed IEEE-1580, Type P, marine shipboard cable may be used.

UL understands that the Correlating Committee appointed a task group to address several issues involving the use of the terms “listed” and “labeled,” most importantly, to clarify and establish a distinction between the terms “listed” and “labeled” which are often used interchangeably. UL supports the need for this task group. However, UL does not expect the work of this task group to affect the 2017 NEC regarding the issue of “listed and labeled.” As such, UL is submitting comments to request that the words “and labeled” be added in various locations throughout the Code for the reasons expressed in the public inputs UL submitted on this issue. UL believes that these revisions will address an ongoing problem that should not wait until the 2020 NEC for resolution.

Subsequent to the Public Input Code Panel Meetings, UL has discussed this issue with its Electrical Council whose membership includes many AHJs. The proposed revisions to the NEC received general support from the membership. This issue was also discussed at a NEMA – NRTLs Forum held on August 14, 2015 at NEMA Headquarters. UL reiterated its support for the proposed revisions. The NRTLs represented at the meeting voiced no objection to the proposals.

The rationale for the revision was simple, to provide information to the AHJ regarding the suitability of equipment they encounter. The mark on the product is the manufacturer’s attestation that the product is in compliance with the appropriate standard. NRTL’s conduct factory surveillance of products, surveillance is one method to validate the manufacturer’s attestation. Should a product be found not to be compliant the manufacturer has the option of removing the mark and shipping the product without the mark, or holding the shipment and bringing the product into compliance. In either case the “Listing” is not impacted, as the “listing” is created at the completion of the “original” certification of the product and indicates the authorization but not the mandate to label products. So the only true way an AHJ can determine whether the product he is seeing is compliant with the applicable standard is via a label on the product. Taking it one step further, listings change with time. It is quite possible that a “listing” has been withdrawn; however labeled product may still be available for sale. Should equipment that is labeled, but not listed, be deemed acceptable? Based on the NEC definitions, it is possible to have a product that meets the Article 100 definition of listed but the testing organization made the manufacture remove the label for a non-compliance issue.

As for the concerns of products that are too small to be labeled, the definition of labeled is not limited to an actual label, it also includes symbols, or other identifying marks. The Safety Standards which define the listing requirements do not address labeling of products as defined by Article 100. As a general rule, NRTL’s do not consider a product as being listed unless it is also labeled. The UL White Book states that “Only those products bearing the appropriate UL Mark and the company's name, trade name, trademark or other authorized identification should be considered as being covered by UL's Certification, Listing, Classification and Follow-Up Service. The UL Mark provides evidence of listing or labeling, which may be required by installation codes or standards.” Again the requirements for the UL Mark are not a Safety Standard requirement, they are a UL requirement and the only way to show that a product is UL Certified (Listed); other NRTL’s have similar requirements.

Committee Statement

CommitteeAction:

Rejected but held

Resolution: The inconsistent actions on Public Inputs to globally change the term “listed or labeled” to “listed and labeled” resulted inmultiple inconsistencies through the NEC and created conflicts with other Codes and Standards that use the term. CMP-1understands that the NEC Correlating Committee took action to develop a first revision that restores the NEC rules usingthe term listed or labeled to how those rules appeared in the 2014 edition. CMP-1 also understands that the NECCorrelating Committee has formed a Task Group to globally review the use of the term “listed or labeled” throughout theNEC and determine a simplified solution that addresses the terms listed, labeled, and their associated informational notes.The Task Group is to address the concerns and input from multiple qualified electrical testing laboratories and work towarda simple solution that resides within Article 100 and perhaps Article 110. The work of that task group is just getting startedand may include proposed revisions to these existing definitions and associated informational notes. CMP-1 recognizes itis premature to incorporate the proposed revisions and informational note at this time.

Labeled.

Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that isacceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection ofproduction of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriatestandards or performance in a specified manner.

Informational Note:. When a listed product is of such a size, shape, material or surface texture that it is not possible to applylegibly the complete label to the product, the complete label will appear on the smallest unit container in which the product ispackaged.



Definition_Labeled_PC.JPG334.6 Requires NM cable to be listed, the UL Guide Information indicates the UL Mark (Label) is on the attached tag, coil, reel, or on the smallest unit container in which the product is packaged.

Definition_Labeled_PC_2.JPG358.6 requires that EMT fittings are to be listed, the UL Guide Information indicates that the UL symbol is on the product and the Mark of UL is on the smallest unit container in which the product is packaged.


Based on CMP1’s comment to PI 881; “Labeling of listed equipment is not possible in all cases or conditions such as if products are too small to be labeled or for some severe environmental conditions” and CMP 8’s comment to PI 895; “Some Listed products are marked or require markings on the smallest shipping package” it appears this informational note may to be necessary. Both the concerns of CMP1 and CMP 8 appear to be in agreement with the substantiation of PI 881.

By adding this informational note, it explains to an AHJ that even though a section of the NEC may require a product to be labeled, it is acceptable to have the label, symbol, or other identifying mark applied to the packaging or a tag in some instances. Without this informational note, if interpreted verbatim by the AHJ, this definition requires the label, symbol, or other identifying mark to be attached to the equipment or material. Without this informational note, AHJ’s may not accept a label that is affixed to the packaging where permitted by the certification organization.

The only thing not allowed is LTFMC and FMC both are made with steel and have the same strength as the armored cable and should be allowed. It would be valuable to have some flexibility in the field for an outdoor or indoor installations. You would only need to reference a metallic raceway and eliminate the laundry list. Metal outlet boxes and junction boxes is to narrow of an allowance, a more general statement covering most installation would be Metal boxes, conduit fittings and enclosures. The current language is confusing, “permitted to be omitted” and appears at the end of the paragraph. Say what this is for (no AFCI) and the give the requirements (Steel everything).

ETL Essential Guide to Product Testing & Certification 2014/2015 North American Edition. Please review document page numbers 5, 8 and 10 to see that ETL has requirements similar to UL, that products that do not bear their certification (listed) mark are not considered by ETL as being listed.


CMP 1 within the committee statement stated "This section currently aligns with common labeling requirements in product safety standards," the product safety standards do not include requirements for certification (listing) labels. The statement also stated "Labeling of listed equipment is not possible in all cases or conditions such as if products are too small to be labeled or for some severe environmental conditions. Manufacturers require the flexibility afforded for listed products relative to when labels should be applied and when the information on the smallest package is sufficient, and practical." This statement seems to reinforce the need for an informational note to the definition of labeled as submitted under PI 1072.

UL recognizes the Correlating Committee created a global First Correlating Revision (FCR) which directed that in all locations where the term “and labeled” was added after “listed” during the First Revision Stage, the words “and labeled” after “listed” be deleted, returning to previous text.
