1 National Fire Protection Association 1 Batterymarch Park, Quincy, MA Phone: Fax: M E M O R A N D U M TO: FROM: NFPA Technical Committee on Lightning Protection Kimberly Shea DATE: December 3, 2012 SUBJECT: NFPA 780 ROC TC FINAL Ballot Results (A2013) According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot. 28 Members Eligible to Vote 1 (G. Berger) 25 Affirmative on All 2 s (W. Heary, R. Rapp) 0 Abstentions The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each Comment. Votes received from alternate members are not included unless the ballot from the principal member was not received. There are two criteria necessary for each first revision to pass ballot: (1) simple majority and (2) affirmative 2/3 vote. The mock examples below show how the calculations are determined. (1) Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (20 members eligible to vote 2 = = 11) (2) Affirmative 2/3: Assuming there are 20 vote eligible committee members, 1 ballot not returned and 2 abstentions, the number of affirmative votes required would be 12. (20 members eligible to vote 1 not returned 2 abstentions = 17 x 0.66 = = 12)

An Example is if a AHJ determines that a 100' radius should be applied and not the 150', then not only the geometry but a human has determined the zone of protection. The statement, as written, is incorrect. Morgan, M the word "fix" should be "for" the word "Donners" should be "Dormers" the word "roar" should be "roof" the phrase "one-lo-two zone" should be "one-to-two zone" Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 64 ) Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 84 )

The lack of "technical substantiation" has been used by this committee to reject recommendations in this ROC as well as past ROC's. General - Many of the conclusions in this section and in other locations of this document are based on IEC document. The NFPA 780 document is a "stand alone" document that is now relying upon a Non U.S. Standard Writing Organization as the basis for a U.S. Based Installation Standard document. Morgan, M.

Galvanized steel has been used in the U.S. electrical industry with decades of history as a substantiation for approving it. Reference NFPA 70, Para (3), (5) (a), Para (A) (1), (B) (1) and 344 (C). If we can reference the "Non-U.S. based" IEC Standards as a basis for this document judgments, surely we can refer to a U.S.'s NFPA Standard for the Electrical Industry in a similar fashion. Guthrie, M. I believe better wording in the Committee Statement would be that galvanized steel has a history of corrosion in some soil conditions Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 41 ) Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 42 ) Eligible To Vote:28 Affirmative: 26 : 1 Abstain: 0 : (Log # 55 ) Rapp, R. The document has not set a benchmark or a definition for "high grounding system resistance" unless there is a basis for what is high or low system resistance, we have done nothing more than referenced a "Non-U.S. based standard" for a U.S. base standard, even in the Appendix.

The submitter is encouraged to provide supporting information to the committee for future consideration. While the lightning channel may contain temperatures of 50,000 degrees, lightning protection conductors primarily conduct current so this temperature will not appear along the length of the down conductor. The primary thermal consideration for down conductors is ohmic heating resulting from lightning current density Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 46 )

We would like to take this opportunity to provide further comments on the relevant chapter in the ROC, understanding the late stage in the current cycle, much of this feedback is position and on an interpretive nature. -General Comment; The PV industry refers modules, not panels as we have stated. In the future maybe we can clarify this. The scope of this chapter is for thermal and PV systems, therefore at this point changing panel to module across the board is not appropriate. However deference to these differences could be defined in the definitions of this document going forward -General comment; PV or photovoltaic terminology, to align with NEC which one should be used consistently (1) change solar panel to thermal solar panel (2) change solar panel to thermal solar panel (4) change DC solar array to PV output circuit Surge protection in accordance with 4.20 shall be provided on the DC output of the solar panel from positive to negative, positive to ground and negative to ground, at the combiner and re-combiner box for multiple solar panels photovoltaic output circuits, and at the AC output of the inverter or paralleled inverters change panel/s to circuits change panel s to circuit Franklin, D. I do not believe the text of was the intent of the committee. I believe the intent was to mount to frame only at panel arrays Strike termination devices shall not be secured directly to the panels or panel frames of photovaltaic panels and arrays.

13 12 Harger, T. These comments are the result of a teleconference that occurred November 29, This teleconference included a dozen people and was a reaction of a group of interested individuals in the photovoltaic systems industry to the proposed chapter 12 being published in the ROP. Three of the participants are NEC Code Panel 4 members. This teleconference included three members of the Solar Panel Task Group of the NFPA 780 TC. Many of the concerns of the PV industry were actually addressed by the TC in CC5, which this group had not seen. The group did have comments and concerns regarding terminology in the proposed chapter 12 and terminology used in Article 690 of the NEC. The proposed chapter 12 is intended to cover all types of solar systems and thus that term was used. Unfortunately that terminology caused confusion when used in reference to PV systems. In an effort to coordinate with Article 690 of the NEC and provide clarification, the task group offers the following comments: (1) change solar panel to thermal solar panel (2) change solar panel to thermal solar panel (4) change DC solar array to PV output circuit Surge protection in accordance with 4.20 shall be provided on the DC output of the solar panel from positive to negative, positive to ground and negative to ground, at the combiner and re-combiner box for multiple solar panels photovoltaic output circuits, and at the AC output of the inverter or paralleled inverters change panel/s to circuits change panel s to circuit I believe these comments to be editorial in nature and clarify the intent of the new chapter. This will make the chapter more useable. Although late in the cycle of NFPA , this teleconference was very beneficial to all involved. It served to highlight the TC s original intent of this new chapter was to include requirements for dealing with these systems on structures with lightning protection systems, as well as when desired, provide guidance for the protection for these systems where they are ground mounted or mounted on structures without a lightning protection systems. It was not the TC s intent to mandate lightning protection systems for all solar or PV systems installed throughout the country. As with all buildings, it is appropriate to do a risk assessment to determine the need for lightning protection. It also served to highlight the need for full collaboration with industry in standards development Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 82 ) Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (New) (Log # 83 ) Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : (Log # 61 ) Eligible To Vote:28 Affirmative: 27 : 0 Abstain: 0 : 1 A (New) (Log # 37 )
