3 51 of /1/ :02 AM Public Comment No NFPA [ Section No ] Uses Permitted. Type AC cable shall be permitted as follows: (1) For feeders and branch circuits in both exposed and concealed installations (2) For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)(3)(3) (3) In cable trays (4) In dry locations (5) Embedded in plaster finish on brick or other masonry, except in damp or wet locations (6) To be run or fished in the air voids of masonry block or tile walls where such walls are not exposed or subject to excessive moisture or dampness Informational Note: The Uses Permitted is not an all-inclusive list. This added language is confusing as to the application of AC cable in health care facilities. The text is unnecessary and will cause needless confusion for installers and AHJs.

4 52 of /1/ :02 AM Public Comment No. 559-NFPA [ Section No ] Uses Permitted. Type AC cable shall be permitted as follows: (1) For feeders and branch circuits in both exposed and concealed installations (2) For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)(3)(3) (3) (4) In cable trays (5) In dry locations (6) Embedded in plaster finish on brick or other masonry, except in damp or wet locations (7) To be run or fished in the air voids of masonry block or tile walls where such walls are not exposed or subject to excessive moisture or dampness Informational Note: The Uses Permitted is not an all-inclusive list. IEEE statement opposing the First Revision:FR1807 The inclusion of For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)(3)(3) in the uses permitted section is not typical. There was already an Information Note: The Uses Permitted is not an all-inclusive list. and this inclusion does not provide additional technical use in application for the installation just more specific as to location(s). Article 517 is specific to Health Care Facilities and should list the type of cable for the system specified per CMP15 jurisdiction.

5 53 of /1/ :02 AM Public Comment No. 79-NFPA [ Section No ] Uses Permitted. Type AC cable shall be permitted as follows: (1) For feeders and branch circuits in both exposed and concealed installations (2) For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)(3)(3) (3) In cable trays (4) In dry locations (5) Embedded in plaster finish on brick or other masonry, except in damp or wet locations (6) To be run or fished in the air voids of masonry block or tile walls where such walls are not exposed or subject to excessive moisture or dampness Informational Note: The Uses Permitted is not an all-inclusive list. Adding this specific permission to use MC and AC for these Article 517 applications strongly implies that other cable and raceway wiring methods that do not include this specific permission in their respective xxx.10 sections are not acceptable for these Article 517 applications. For example for EMT does not have this specific permission.

Type AC cable shall be permitted as follows: (1) For feeders and branch circuits in both exposed and concealed installations (2) For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)( 3)(3) (3) In cable trays (4) In dry locations (5) Embedded in plaster finish on brick or other masonry, except in damp or wet locations (6) To be run or fished in the air voids of masonry block or tile walls where such walls are not exposed or subject to excessive moisture or dampness Informational Note: The Uses Permitted is not an all-inclusive list. The Panel statement shows that Panel 7 requested Panel 15 review. Panel 15 has subsequently resolved all PI s allowing the use of AC Cable in (C)(3)(1). Therefore, this PI should be resolved, since there is no permitted use for AC cable in those locations. Leaving this text could lead to confusion and misinterpretation of NEC requirements.

7 55 of /1/ :02 AM Public Comment No. 260-NFPA [ Section No (A) ] (A) General. Type AC cable shall be supported and secured by staples, listed cable ties identified as Type 2S or Type 21S listed and identified for securement and support, straps, hangers, or similar fittingsor fittings or other approved means designed and installed so as not to damage the cable. The language of all cable tie-related FR s between CMP 7 and CMP 8 should be harmonized. The difference between the CMP 7 FR s (1809, 1815, 1821 and 1830) and the CMP 8 FR s (2166, 2170, 2104 and 2115) is that those from CMP 7 maintained the cable tie Type classifications. CMP 8 removed these Types with the following committee statement: Listing of cable ties approved for support of flexible conduits and cables is appropriate as the standard requires markings that identify critical performance ranges that can impact their suitability for use, including minimum and maximum operating temperature and resistance to ultraviolet light for outdoor installations. The proposed new requirements will provide objective determination for suitability of cable ties for this use.

For example luxury vinyl use in commercial buildings rose 32.5% in 2014 alone. These alternate floor coverings offer the building owner a highly attractive and low maintenance flooring. However they still need/demand the ability to provide power and data to open areas which do not have traditional cabling pathways and need/want the flexibility of using both FCC (Flat Conductor Cable - power) in the same manner that they are presently allowed with carpet squares. Often the installation of FCC cable is the only acceptable solution to providing powering to the middle of the room. UL

11 Public Input No NFPA [Article 324] (Alternate Flooring) Committee Statement Resolution: This cable was originally designed to be installed under removable carpet squares for easy inspection and maintenance. The proposed methods indicated in the PI could potentially cause damage to the cable and unforeseen consequences. CommScope Input to Resolution of Public Input 2627-NFPA [Article 324] (Alternate Flooring) CommScope (previously TE Connectivity BNS Division and the original submitter of Public Input 2627) does not agree with the committee s resolution and strongly believes that FCC (Flat Conductor Cable) can be both safety installed and maintained and easily accessed when installed under modular tiles and planks. Most if not all flooring installers would agree that removal of a modular tile and plank floor (such as laminate, luxury vinyl or hardwood) is as easy to remove if not more so than carpet squares. This is even true when the removal process must occur in the middle of the room. First, as a reminder UL Fact-Finding Report (File: E732213, Project ) originally submitted finds that FCC cable is safe to be installed under these various forms of modular planks and tiles. Second, it is required that FCC cable when installed is covered by top shield a layer of stainless steel. Between this and the copper conductors in the cable locating a FCC cable under a floor with a simple metal detector would be extremely easy. This means that adjacent tiles or planks to the FCC cable requiring cutting could be located eliminating safety concerns. Third, it is common practice within the flooring industry to remove modular tile and planks given that damage to the floor itself can occur. While typically this is done starting at the baseboard closest to the area where you need access, it can also start in the middle of the room without difficulty. Just a simple search on YouTube provides a number of videos on how this it done. Listed below are just three of the videos. Plank/Tile Replacement Moduleo LVTY Click Flooring (Removing a Luxury Vinyl Plank from the Middle of the Floor) Mannington Mills How to Replace a Laminate Flooring Plank (Removing Laminate Plank from the Middle of the Floor) Quick-Step Laminate Flooring Installation Unifix Tool (Special tool to make access to a Middle Plank even Easier) Below we provide instructions from public information on removing a modular tile or plank:

12 Laminate Flooring Removal You want to apply blue tape a ¼ in to the existing planks, around the perimeter of the plank to be repaired. This will help you identify the plank to be repaired and help prevent an overcut. Mark dots for drilling holes an 1/8 from the edge, at all four corners of the plank. Mark two more dots at each head seam, 3 from the head seam and 2 from the side seam. Take a short square and connect the dots diagonally, then connect the four inside dots. These lines are a guide to cut and remove the damaged plank. Drill all 8 holes with the 3/8 drill bit. With gloves, safety glasses and a dust mask. Set your skill saw to the plank thickness, and carefully cut the lines connecting the dots. Remove the center piece with a chisel. At the corners with the chisel carefully break the diagonal piece at the head seams loose. Remove these sections and carefully remove the side pieces. Vacuum the cut area well, and remove all loose debris. Use the packaging tape to cover any damaged underlayment. Using a chop saw remove the tongue and groove at the end seams. While removing, use caution not to cut into the bevel or laminate. Using a table saw remove only the tongue on the long side. The blade must be set to the top of the tongue. At the cutout section remove 1 of the tongue on the head seam, starting at the groove on the tongue side with the small square and a utility knife. This will allow the plank to seat properly. Make sure the area is clean and you can dry fit the plank to be installed. With the plank removed, apply a good bead of Mega Glue around the perimeter. Make sure you apply on top of the head seam tongue and in the grooves. Install the new prepared plank by hinging the plank into place, putting long side groove into the long side tongue. Wipe off the excess adhesive with a damp cloth. Apply weights along the glued edges. After 24 hours remove the weights, peel up the tape and walk away. Luxury Vinyl Flooring Removal Repairing LockSolid Luxury Vinyl Flooring is a straight forward process. If the damaged plank is near an outer edge just un-click everything to the area, replace the damaged plank and re-click back together. If the damaged area is in the middle of the room it may be best to cut out the center of damaged piece and carefully remove it. Prepare the replacement plank by completely removing the groove strip on both the short and long profile. Using the decorative as a guide on the opposite (tongue) short end of replacement plank cut off the overhanging tongue. All cuts can be made using a sharp utility knife. Position the prepared replacement plank by engaging the tongue of the long side into the groove of the adjoining plank. Hinge the replacement plank into position. Check the fit before sealing. Trim the underside of the groove if necessary. Once plank it prepared properly and the plank fit tested. Lift the replacement plank high enough to apply a bead of MCS-42 seam sealer around the perimeter. Place plank into position, use hand roll if necessary, remove excess sealer from surface with a dampened mineral sprit cloth.

13 Lastly, we understand that some committee members questioned the necessity of allowing modular tile and plank flooring to be allowed. Commercial and retail building owners are rapidly adopting alternate flooring covering for use in their facilities in addition to or instead of carpet squares, such as modular vinyl planks and tile, laminate and hard wood. In a recent article by Floor Covering News, they reported the statics on 2014 flooring sales. The study/article reports that resilient flooring another term for modular tiles and planks since 2009 has increased a stunning 36.6% by Resilient flooring now accounts for 15.1% in volume of the flooring industry. They also reported that LVT (Luxury Vinyl) sales have risen 52.3% in just two years. The use of LVT in commercial buildings rose 32.5% in 2014 alone. These alternate floor coverings offer the building owner a highly attractive and low maintenance flooring. However they still need/demand the ability to provide power and data to open areas which do not have traditional cabling pathways and need/want the flexibility of using both FCC (Flat Conductor Cable - power) in the same manner that they are presently allowed with carpet squares. As product manager for UnderCarpet cabling I receive calls weekly from new and existing clients wanting to install FCC under modular tiles and planks. When I inform them of the NEC Code requirements that it has to be only under carpet squares, they strongly express their displeasure and their need for this application to be allowed because FCC often is the only acceptable solution to their requirement. CommScope requests that the committee revisit it position and accept Public Input 2627-NFPA

14 59 of /1/ :02 AM Fact Finding Report finds that FCC cable can safety be installed under these alternate floors. Modular tiles and planks are as easily removed as carpet squares allowing for access and maintenance of FCC cable.

15 60 of /1/ :02 AM Public Comment No NFPA [ Section No ] Listing Requirements. Type FCC cable and associated fittings shall be listed and labeled. Additional Proposed Changes File Name Description Approved Essential_Guide_to_Product_Testing_and_Certification_NOV_2014.pdf 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. 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. 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.

17 62 of /1/ :02 AM Public Comment No. 494-NFPA [ New Section after ] Public Comment on Panel 7 results for PI#3753 As co-authors of Public Input #3753 our intent was to allow under floor wiring systems in schools and hospital non-patient care areas to address the need for power in open offices, classrooms and training rooms. The products that meet Article 324 provide a system of power distribution without a tripping issue that other floor solutions create. Given the Panel 7 concerns of safety in schools and hospital buildings we began working on installing Beta Sites in schools to demonstrate that Article 324 products do provide a safe environment. During the process we discovered that the school solution would be best served using low voltage (Class I and II). After further investigation and research we found that there are a number of low voltage (Class 1 and II) products that can be used to provide a safe environment in schools and hospital non-patient care areas. Based on our discovery we would submit the following language to enhance the Electrical Code under Article (4). Add: Exception 1: Class I and II wiring systems, listed for the use, are allowed in school class rooms, offices, laboratories, lounges and libraries when installed in compliance with Article 725. Exception 2: Class I and II wiring systems, listed for the use, are allowed in hospital conference rooms, training rooms, lounges, nurse s stations and offices when installed in compliance with Article 725. Sherman Robbins Consultant for Bretford Manufacturing shermanrobbins46@gmail.com Problem: Accessing power source at the point of use in schools and hospital non-patient environments with open class rooms, conference rooms, libraries, laboratories, teacher lounges and offices. Current solutions for existing spaces are cumbersome and expensive to install, and if they are not routed through trenches will create a tripping hazard. Technology is evolving rapidly and the need to incorporate low voltage into our space planning is growing exponentially. Our proposal would provide the ability to access the power source for powering lap tops, cell phone charging, tablet use and recharging, LED lighting and energy saving controls in open rooms at the point of use with the ability to make changes to the space as technology changes. Class I and Class II wiring systems, listed for the use and installed under the requirements of Article 725 would provide additional safety to the end user. Flat Conductor Cable, Article 324, provides flexibility of installation, safety of installation and eliminates tripping hazards to the occupants. Currently 57% of our schools (K-12 and Colleges) and 62% our hospitals were constructed prior to the influx of technology that is now needed to perform our daily work and to meet our needs for teaching and learning. Flat Conduct Cable, Article 324, allow existing infrastructures to be upgraded quicker and less expensively to meet today's and tomorrow's technology tools.

19 Public Input No NFPA [Section No ] (School and Patient Room Exception) Committee Statement Resolution: This FCC cable first accepted via Proposal 31 as a new article for the 1981 NEC. The restrictions noted in were present since that time. The PI does not include any technical information in support of removing any of these restrictions. CommScope Input to Resolution of Public Input 3753-NFPA [Section No ] (School and Patient Room Exception) CommScope (previously TE Connectivity BNS Division and the original submitter of Public Input 3753) does not agree with the committee s resolution and strongly believes that FCC (Flat Conductor Cable) should be allowed in schools and non-patient care areas of the hospital. In regards to an environment that is close to schools, especially elementary schools, FCC cabling systems have been installed into over a hundred Chuck E. Cheese (CEC) restaurants. Chuck E. Cheese has been using UnderCarpet power and data cabling systems from TE Connectivity / CommScope in their retail gaming area of their stores for over 5 years. CEC restaurant has on average 15 individual power runs with an average of 40 UnderCarpet power outlets per restaurant. They utilize the UnderCarpet cabling system to supply power to the individual games within their retail gaming area. They have had great success with the UnderCarpet system, little to no issues, and continue to deploy the UnderCarpet cabling in both new builds and retrofits. Of course they find the system to be very safe even when expose to children as in their retail gaming area. The UnderCarpet cabling system solves a significant issue of supplying power to locations in the middle of the store eliminating the need for costly concrete sawing, unsightly power poles and avoids extension cords and trip hazards. CommScope believes and has found that the FCC cabling system offers no more safely risks and maybe less than traditional wiring. The FCC cabling is concealed and protected all the way from the transition point typically in the wall to the convenience outlet in the middle of the room. It is not only protected by the floor covering but also the required top shield (layer of flat stainless steel). The convenience outlet is actually safer than a normal duplex outlet in that one must slide the protective cover back to can access to the duplex receptacle. Probably the biggest increase in safety will occur by providing the schools a

20 cost-effective, easy solution for providing power in the center of the room versus unfortunately what is done today which is extension cords and power strips, resulting in trip and fire hazards. In non-patient areas of the hospital the safety requirements are no more demanding than any traditional commercial building or retail store. CommScope UnderCarpet cabling system has hundreds of thousands active and safe installations in all sorts of commercial buildings and retail stores. CommScope has researched available records concerning the original adoption of Article 324 and the inclusion of these restrictions present in Article and has concluded these restrictions were adopted not because of technical reasons or additional requirements but because of a compromise between proponents and opponents of FCC cabling. Quite naturally in 1981, the proponents of FCC were willing to compromise on schools and hospitals because 1) these applications at that time were almost exclusively glue tile floors which would not allow FCC cable to begin with and 2) the need for powering and communications in 1981 in these applications were minimal. This has tremendously changed in both the flooring used in schools and hospitals and also with their demand for power in the middle of the room. The proliferation of thinner lap tops, tablets and smart phones now perform the same task that the desk top computer once performed, which has changed the workplace and educational footprint. Based on the 2000 annual report from BIFM (Business and Institutional Manufactures Association), the type of work and training that takes place today is also very different from the work and training that was performed in 1980 s. Today our work and training requires more collaborative interaction which has driven design changes to our workspaces. Also, to encourage collaborative interaction, these environments also required flexibility in constant re-arranging to bring the right workers and students together throughout the day to accomplish task. Interior designers have developed workplace settings to meet these evolving needs. In general, the designs of these spaces are in open room environments using tables and desk for work tops, with little to no access to the building s perimeter wall outlets. Bringing power to these spaces has been addressed through a few different methods. One, power poles dropping down from the ceiling, two, raised floors and three FCC systems. Each of these have their own pro s and con s, but the one system that creates the most flexibility, creditability and least amount of re-construction cost is the FCC systems. FCC systems have been proven to be safe and reliable when installed and maintained in accordance with the NEC 70 electrical code. School classrooms, computer laboratories, administration offices, teacher lounges, student lounges, reception workstations, social meeting areas, media centers and libraries do not present safety risks that are not already provided for within the current electrical code. Likewise, non-patient care and non-patient rooms in hospital and emergency care centers, such as administrative offices, training rooms, media centers, reception workstations and social meeting areas do not present safety risks that are not already provided for within the current electrical code. CommScope requests that the committee revisit it position and accept Public Input 3753-NFPA

21 64 of /1/ :02 AM Public Comment No. 959-NFPA [ Section No ] Insulation. The insulating material of the cable shall be moisture resistant and flame retardant. All insulating materials in the FCC systems shall be identified for their use. Informational Note: The requirements associated with the term flame retardant for each type of cable or insulation are contained within the product standard for the relevant cable or insulation (See also ). The panel stated that the testing requirements are not needed for this article. The informational note proposed is being revised to explain that information on the term flame retardant is contained in the product standard. This is important because the term "flame retardant" as such is not an appropriate term without clarification because the term flame retardant simply refers to the additives that are used to improve fire performance, unless the fire performance is clarified.

22 65 of /1/ :02 AM Public Comment No. 261-NFPA [ Section No ] Support. Type MV cable terminated in equipment, installed in pull boxes, or in vaults shall be secured and supported by metallic or nonmetallic supports suitable to withstand the weight, by listed cable ties listed and identified for securement and support, or other approved means, at intervals not exceeding 1.5 m (5 ft) from terminations or a maximum of 1.8 m (6 ft) between supports. The language of all cable tie-related FR s between CMP 7 and CMP 8 should be harmonized. The difference between the CMP 7 FR s (1809, 1815, 1821 and 1830) and the CMP 8 FR s (2166, 2170, 2104 and 2115) is that those from CMP 7 maintained the cable tie Type classifications. CMP 8 removed these Types with the following committee statement: Listing of cable ties approved for support of flexible conduits and cables is appropriate as the standard requires markings that identify critical performance ranges that can impact their suitability for use, including minimum and maximum operating temperature and resistance to ultraviolet light for outdoor installations. The proposed new requirements will provide objective determination for suitability of cable ties for this use.

IEEE statement opposing the First Revision:FR1818 The inclusion of For life safety and critical branch circuits of the essential electrical systems in health care facilities where permitted by (C)(3)(1) and (C)(3)(3) in the uses permitted section is not typical. There is an Information Note: The Uses Permitted is not an all-inclusive list. and this inclusion does not provide additional technical use in application for the installation just more specific as to location(s). Article 517 is specific to Health Care Facilities and should list the type of cable for the system specified per CMP15 jurisdiction.

The Panel statement shows that Panel 7 requested Panel 15 review. Panel 15 has subsequently resolved all PI s allowing the use of MC Cable in (C)(3)(1). Therefore, this PI should be resolved, since there is no permitted use for MC cable in those locations. Leaving this text could lead to confusion and misinterpretation of NEC requirements.
