20 1 st par T AVCON, INC. Improper use of the term counterpoise, see definition NFPA 780 3.3.7.2 and Chapter 11 Accepted and removed the reference to counterpoise. First sentence reads as follows: For buildings that exceed 18 m (60 ft) in height, these bonding connections shall be made to a ground loop conductor.
20 2 nd par T AVCON, INC. Section 250.60 of the National Electrical Code (NEC) provides the restriction from using components of a lightning protection system as grounding electrodes for electrical power systems. The requirement to bond the two systems together must be adhered to as required in Section 250.106. This rule specifies that the grounding electrode system of the lightning protection system be bonded to the electrical service grounding electrode system but does not specify a size of the bonding conductor. Section 250.66 should be correct reference. 250.66C provides sizing information, however, NFPA 780 sizing should probably be used in lieu of NFPA 70 since NFPA 780 conductors are sized for lighting protection not just for electrical systems. Accepted in Concept and Part. Reason: Section 250.66 refers to minimum sizes of grounding electrode conductors. Section 250.66(C) addresses maximum sizes of grounding electrode conductors for an electrical power service when connected just to a ground ring electrode. Section 250.60 and 250.106 are provided in the NEC to indicate restrictions from using a power system grounding electrode as a lightning protection system ground loop. A new added sentence provides users with information about sizing conductors that are part of a lightning protection system. The text in this section is revised as follows to address the submitter s concerns and improve clarity: Section 250.60 of the National Electrical Code (NEC) provides a restriction from using components of a lightning protection system as grounding electrodes for electrical power systems. The requirement to bond the two systems together must be adhered to as required in NEC Section 250.106. This rule specifies that the grounding electrode system of the lightning protection system be bonded to the electrical service grounding electrode system but does not specify a size of the conductor that must be installed to bond the two systems together. Sizing requirements for lightning protection system conductors are provided in NFPA 780.

7.1.2. Testing Maxwell Lighting Section 6.2 is not correct. Recommend stating use NFPA780 (annex) grounding and measurement techniques. Accepted and incorporated revised and expanded text as follows: 7.2.1 General IEEE Standard 81 describes several different methods in which to test the resistance of a grounding electrode or a grounding electrode system, among those methods are the three-point fall of potential method and the clamp-on test. NFPA 780 Annex E describes the principals involved with the three point fall of potential test and how it can be used with small and complex grounding electrode systems. The Clamp-on test method is used predominantly to test individual electrodes but it has limitations. 7.2.2 Fall of Potential Method This method requires that the grounding electrode or grounding electrode system be isolated from the electrical power system if the utility uses a multigrounded neutral system. It must also be isolated from the telecommunications ground as well as any other building grounds. Tests should be performed on individual grounding electrodes and the results recorded over time. Any increase of resistance from the original test reading may indicate deterioration of the grounding electrode. When using grounding electrodes in conjunction with a ground ring, it may not be possible to test the individual electrode. In this case the entire system should be tested while isolating it from other building grounds. 7.2.3 Clamp-On Method The clampon method requires that the grounding electrode or grounding electrode system be connected to the electrical power system using a multi-grounded neutral system or another zero reference source. Proper placement of the unit is essential in order to obtain a correct reading. The grounding

NEIS are not intended for mandatory application but serve to fill the gap related to what constitutes good workmanship related to lightning protection system installation and design. Included a provision in 4.3 requiring lightning protection conductors and components to be listed (certified) to appropriate product standards. This requirement is also provided in Clause 5.9.1.
6 1.2 (b) E Rebane As a minimum, all tasks shall be performed under the supervision of a qualified person. IMHO, that requirement should be extended to include persons that perform technical tasks as well, but that is your decision N/A Accepted in concept. See the revised and expanded text that deals with training and experience and also requirements for qualified persons as defined in NFPA 70 and NFPA 70E. Requirements (a) Regulatory. All information in this publication is intended to conform to the NFPA 780 Standard for the Installing Lightning Protection Systems and applicable requirements in the NFPA 70 National Electrical Code. Installers should always follow and apply the applicable requirements contained in NFPA 780 and NFPA 70, in addition to applicable state and local codes, and manufacturer's instructions when installing electrical equipment and systems. (b) Training and Experience. Installation of lightning protection systems requires special skills and training. Only trained and experienced personnel familiar with the construction and installation of lightning protection systems and associated equipment should perform the technical work described in this publication. Some regulatory bodies may require certification or licenses that demonstrate credentials and experience. Administrative functions and other tasks can be performed under the supervision of a trained and experienced person. See Annex A of NFPA 780. (c) Qualified Persons. Installations of surge protective devices (SPDs) and other portions of the lightning protection system that are covered by NFPA 70 National Electrical Code and NFPA 70E, Standard for Electrical Safety in the Workplace (ANSI). These portions the system installation shall be performed by qualified persons and shall be in accordance with the applicable provisions of the NEC and
6 1.2 (c) E Rebane I recommend that compliance with NECA 1 be mandatory, see Clause 5.1 Accepted and incorporated revised text as follows in Section 1.2: (d) Workmanship. General requirements for installing electrical products and systems are described in NECA 1, Standard for Good Workmanship in Electrical Construction (ANSI) and not all provisions in NECA 1 would apply to lightning protection system installations. Other National Electrical Installation Standards provide additional guidance for installing particular types of electrical products and systems. NECA 781 provides workmanship provisions for lightning protection systems including system design, maintenance, quality, and performance criteria. A complete list of NEIS is provided in Annex E. 12 4.2 E Rebane This Clause should carry a warning that changes to construction documents (is that what is meant by "original drawings?" may not be made without approval of the contracting agency. Accepted and added text to 4.2 as follows: Often changes in the field result in system installations that will differ slightly than as shown in the original plans and specifications. Any changes to an original system design must be coordinated with the original designer or engineering firm. 14 4.3 E Rebane Correct spelling Replace "(SPDS)" with (SPDs)" Accepted 22 5.5.1, the last paragraph on that page T Rebane Moisture and water intrusion through walls and floors warrants additional directions and cautions, similar to that offered for roofs. See the first paragraph of Clause 5.6 and the last paragraph on page 34 (Clause 5.7.2.) 36 5.9.1 E Rebane Correct spelling Replace OHSA with OSHA Accepted Accepted and added text in 5.5.1 as follows: Moisture and water intrusion through walls and floors warrants additional directions and cautions, similar to that offered for roofs.

Correct abbreviation for kilo-amperes Relocate paragraphs in Part 2 describing execution to Part 3. Samples of paragraphs that should be relocated include: 2.03a.2.03b, 2.03c, 2.04.1a through e, 2.04.1g and h,2.05, etc. Relocate paragraph in Part 3 to Part 1: 3.01b and c, 3.03, 3.04d. Replace 20KA with 20kA Accepted and reorganized as suggested. Renumbered the section accordingly. Accepted and revised text as follows: Confirm surge protection devices on electrical service(s) are compliant with the current edition of UL 1449, with 20KA In ALL E HLP Systems Page numbers need to be added. It is very difficult to comment on a certain page number when none are listed. Page numbers we are using in this comment matrix are based on when these document pages fall in their presented order. Add Page Numbers to the entire document including the table of contents. Accepted. Page numbers will be added in the final publishing of the standard. ALL G HLP Systems Proposed NECA 781-201x is not needed. NFPA 780 is already an ANSI standard and attempting to have a second ANSI standard that is less technical that the current recognized ANSI standard would cause conflicts. Concentrate on making this a maintenance standard or document and not an installation standard. As presented it is in conflict with NFPA 780 in many places and is more of a handbook and not a technical document. This document is editorial in nature. Not accepted. NFPA 780 is intended to be a recommended practice that requires that conductors and equipment for lightning protection systems be installed in a neat and workmanlike manner, however, nothing in 780 describes what constitutes neat and workmanlike. That is the whole inspiration behind the National Electrical Installation Standards (NEIS) program. NECA 781 is intended to address quality, performance, workmanship and more specific and detailed maintenance information than NFPA 780 or PLI 175.
1 G HLP Systems 781 is a poor choice of a Standard number. I 2 E HLP Systems Page numbers missing from the Table of Contents. NECA 780 should be used since the attempt here is to somewhat align with NFPA 780. 781 will lead to confusion with the long proposed but never adopted NFPA 781. Add Page Numbers. This designation was accepted by ANSI and is included in the PINS submitted to ANSI. The scopes of NFPA 780 and 781 differ and each are specific to the information covered within each. The standard designation 781 has been cleared with NFPA. Accepted. Page numbers will be added in the final publishing of the standard. 6 1.1 E HLP Systems Lightning is spelled lighting Correct spelling error Accepted and corrected.
6 1.2 B G HLP Systems Paragraph requires the installer to be familiar with the construction and installation of electrical power systems What does this have to do with the installation of Lightning Protection Systems? Change: Only qualified installers under the employ of contractors Listed by Underwriters Laboratories for the purpose of installation of Lightning Protection Systems should perform all work described in this publication. Accepted the comment and completely revised this section to include more detail about required training and experience as well as when qualified persons are required to perform certain portions of some work related to installing a lightning protection systems (such as installing a surge protection unit or system at an electrical service). Test is revised as follows: 1.2 Regulatory and Other Requirements (a) Regulatory. All information in this publication is intended to conform to the NFPA 780 Standard for the Installing Lightning Protection Systems and applicable requirements in the NFPA 70 National Electrical Code.

This paragraph as written is very confusing and is not consistent with NFPA 780 Rewrite to be consistent with NFPA 780 ground ring electrode requirements. Accepted and corrected. Accepted and revised as follows: A ground ring is required by both NFPA 780 and LPI 175 for structures 60 feet or taller. If required, a ground ring electrode for the lightning protection system shall be installed at least 450 mm (18 in.) below the earth unless ground conditions prevent this. There may be confusion as to whether the ground ring electrode is for the lightning protection system ground or for a supplemental electrical ground. If the ground ring electrode is being installed for the purposes of electrical grounding, it shall be installed to a depth of at least 750 mm (30 in.). Ground ring electrodes shall be continuous around the structure and connect to all down conductors. The ground ring electrodes, rods, and other installed electrodes permitted by the standard(s) shall be installed so that it is not affected by freezing-thawing cycles of the earth, (if present).
