Richard D. Currin, Jr. I am in agreement with this revision. The labeling requirements gives needed

information to installers and AHJs to insure a safe installation. Allowing the

information to be in manufacturer's instructions will prevent nameplates from

becoming excessive in size.

Daniel R. Neeser Item 5 should include "zero" as in item 1. This should be considered for the 2020

Richard D. Currin, Jr. This revision addresses the fact that GFCI protection is required for bonded

125/250v generators. It allows an exception for generators with interlocking that

disables 125 v receptacles when the 125/250v receptacles are in use.

Linda J. Little This revision is primarily editorial and provides significant clarity. The only

substantive impact is that on bonded portable generators, the 125-volt

receptacles must be GFCI protected. It is imperative to note that small unbonded

generators that employ only 125-volt receptacles are not required to have GFCI

protection. That has been the concern of the generator manufacturers all along

and SR 3621 does not impact those unbonded generators. Rejection of SR 3621 by

CMP-13 would be an affirmation that bonded generators do not require GFCI

protection for 125-volt, 15/20-amp receptacles, which would directly conflict with

the requirements of section 210.8. CMP-13 has no justification to specifically

permit 125-volt, 15/20-amp receptacles to be applied without GFCI protection on

bonded generators. Why would a manufacturer build a bonded generator and not

provide GFCI protection, particularly when understanding that there is a path for

fault current inherent to the generator and shock hazards exist?

George M. Brandon The word "and" needs to be removed from two sentences. The sentences are

show below, first as they are in the standard and then with the unneeded "and"

removed. Original: Unbonded generators with both 125-volt and 125/250-volt

receptacle outlets shall have listed GFCI protection for personnel integral to the

generator or receptacle on all 125-volt and 15- and 20-ampere receptacle outlets.

Updated: Unbonded generators with both 125-volt and 125/250-volt receptacle

outlets shall have listed GFCI protection for personnel integral to the generator or

receptacle on all 125-volt 15- and 20-ampere receptacle outlets. Original Bonded

generators shall be provided with GFCI protection on all 125-volt and 15- and 20-

ampere receptacle outlets. Updated Bonded generators shall be provided with

GFCI protection on all 125-volt 15- and 20-ampere receptacle outlets.

Neil A. Czarnecki The intent of the public inputs on 445.20 were intended to clarify the existing

requirements of this section. The Panel action to create SR 3621 goes well beyond

clarification, and creates a new requirement that is unnecessarily restrictive and

not technically substantiated.

Affirmative with Comment 2

Richard D. Currin, Jr. Agree because listing is needed to insure products are safe. This provides AHJs and

installers assurance that the batteries installed are suitable for the application.

Linda J. Little This new requirement is necessary to ensure safe operation. Recent failures in the

Boeing 747 Dreamliner and hover-boards have shown that thermal runaway is a

serious fire hazard. The expansion of energy storage into facilities with occupants

mandates that these new battery technologies be tested and certified before

installation in accordance with the NEC.

Negative 1

Neil A. Czarnecki The current ANSI standard for storage batteries is battery chemistry independent,

and as such, does not take the differences in chemistry into consideration in the

safety design process. The addition of a listing requirement will therefore provide

limited benefit to the battery consumer and potentially restricts the

implementation of new technologies and solutions into the electrical industry.

Richard D. Currin, Jr. Agree this change is appropriate.

Daniel R. Neeser An editorial change by the Correlating Committee or NFPA Staff is suggested. The

term “fault-current” in Informational Note No. 2 should be changed to “short-

circuit current” as this term is used in 480.7(D)(2). FR 3643 changed “short-circuit

current” to “fault-current” in 480.7(D)(2) and added Informational Note No. 2, so

there was correlation with the term. However, SR 3630 changed 480.7(D)(2) from

“fault-current” back to “short-circuit current” which is the 2014 NEC term used in

this section. However, the SR did not correspondingly change the term in

Informational Note No. 2 to “short-circuit current.” Since this is an Informational

Note editorial change, it should be permissible.

Richard D. Currin, Jr. There is no evidence to support that 2" of concrete provides a 2 hour rating. In

fact there is evidence that implies the contrary and that it would require 4" or

more of concrete encasement to provide a 2 hour fire rating. I would agree with

this revision if it were limited to the application of slab on grade (SOG) cases. Since

it is not specific to SOG that then ceilings and walls would be allowed as protection

for conductors. This is an area that needs lab test to be performed to determine

temperatures that conductors are exposed too under various levels of concrete

thicknesses as well as different concrete mixes. The test should include conductors

installed on grade, walls, and ceiling/floors.

Shawn Paulsen The term "not capable of self preservation" needs to be defined. An individual

could enter a health care occupancy being capable and for a portion of the stay

not being capable of self preservation. For example would a Dentist office be

considered. As written I believe this term will lead to inconsistent application of

Shawn Paulsen The numbering layout is a bit confusing when reading the entire Rule. The Rule

states that (D)(1)through (D)(3)is to be followed and directly underneath there are

4 requirements. I realize these are not the requirements to be followed and

suggest these 4 additional requirements possibly be lettered in place of

numbering.

Negative 2

James E. Degnan Defining the extent of emergency system construction by building occupancy type

should not be within NFPA 70, instead it should be in the appropriate building

code. Building codes consider multiple aspects of life safety which cannot be

accounted for by an electrical code. Listing these items in NFPA 70 has the

potential to lead to conflicts with building codes, leaving AHJs in quandary. Instead

of expanded, this paragraph should be removed, otherwise it will subsequently

need to add other occupancy types to the list, with all of their corresponding

building code details.

Michael L. Savage, Sr. After much consideration and research I have not been able to locate where the

absence of this requirement has resulted in undo hardship or injury to the building

or inhabitants. The provision for automatic fire sprinklers is already mandated in

these structures as noted in the building and life safety codes, which will provide

not only life safety protection but property protection as well. The archived

materials and fire reports I have read state the sprinkler systems engaged fires

within their respective design times. I recently interviewed a Institutional Use

Construction Manager/Inspector, in preparation for the voting on this revision,

and I was informed they prepare for and practice fire evacuations for their facility

and were against the added cost this proposal would add to additional buildings in

their campus style installation. After researching the NFPA archives for additional

fire data I feel I need to vote negative without any quantitative or empirical

technical substantiation.

Timothy M. Croushore I am in agreement with the additional sections and Part IV of Article 705

referenced in the text of 706.3 Other Articles. However, the action on Second

Revision 3939 needs to be correlated with the action on Second Revision 3645 and

have 705.40 added to the list of referenced sections in 706.3 Other Articles.

Section 706.3 should appear as follows: 706.3 Other Articles. Whenever the

requirements of other articles of this Code and Article 706 differ, the requirements

of Article 706 shall apply. If the ESS is capable of being operated in parallel with a

primary source(s) of electricity, the requirements in 705.6, 705.14, 705.16, 705.32,

705.40, 705.100, 705.143, and Part IV of Article 705 shall apply.

Shawn Paulsen 706.7(D)(3) makes reference to the label including Arc flash risk assessment

information at the disconnecting means meeting the requirements of 110.16. In

reviewing the proposed revisions to 110.16(B) it appear that information related

to the arc flash risk assessment such as: available incident energy, arc rating of

clothing and site specific PPE is being removed. If this proposed change is accepted

for 110.16(B) then 706.7(D)(3) will need to be revised.

Richard D. Currin, Jr. There is no evidence to support that 2" of concrete provides a 2 hour rating. In

fact there is evidence that implies the contrary and that it would require 4" or

more of concrete encasement to provide a 2 hour fire rating. I would agree with

this revision if it were limited to the application of slab on grade (SOG) cases. Since

it is not specific to SOG that then ceilings and walls would be allowed as protection

for conductors. This is an area that needs lab testing to be performed to

determine temperatures that conductors are exposed too under various levels of

concrete thicknesses as well as different concrete mixes. The testing should

include conductors installed on grade, walls, and ceiling/floors.

Linda J. Little We are voting affirmative on SR 3627 with the following comment: It is imperative

that the title of this Article is reconsidered, and if changed, editorial revisions

made throughout. The use of the term “microgrid” may cause serious confusion in

the industry. The term “microgrid” infers utility owned conductors and equipment.

The systems addressed in this Article should be addressed by a term that more

appropriately captures the system itself. This Article could be retitled as

“Interconnected Direct Current (DC) Distribution Systems.” The NEC Correlating

Committee (CC) is well aware of previous issues created in 90.2 with references to

the NESC in informational notes, and the CC formed a task group to resolve those

issues. The CC must understand the significance of this issue and the serious

concerns presented by the electrical utilities represented in this revision stage

with respect to the use of the term “microgrid.” We, the NEC community, would

take serious exception if the National Electrical Safety Code (NESC) would begin to

use and apply the term “premises wiring” to utility owned conductors and

systems. This Article and the work within are important and should be in the 2017

NEC, which is why we are voting affirmative. The NEC CC should seriously consider

removal of the term “microgrid.”

Timothy M. Croushore The term “Microgrid” is a jargon and non-specific term. The NEC process consistently encourages using

terminology that provides clarity. The term “Interconnected Direct Current (DC) Distribution System” provides this

clarity. To ensure that we maintain fundamental separation between utility wiring and premises wiring, we need to

use terminology that provides clear separation between the two systems (NEC and NESC). The electric utility type

microgrid systems are still in the R&D phase and still in development in other standards committees outside the

NFPA. Therefore, as this technology continues to emerge, we need to ensure that the lines do not become blurred

between the two systems. We are mixing two different systems, therefore keeping different terms in the NEC will

best serve the industry. To move forward with the technology of an interconnected DC system and revise the

jargon out of this new Article 712 to a specific term, the 14 following changes to Article 712 needs to be made.

Identifiable portion of the ballot. 1. Revise the title to Article 712 Interconnected Direct Current (DC) Distribution

Systems. 2. In 712.2 Definitions, remove the title, the definition and Information Note for Direct Current Microgrid

(DC Microgrid) and replace it with the following: Interconnected Direct Current (DC) Distribution System. An

interconnected direct current (DC) distribution system is a power distribution system consisting of more than one

parallel connected dc power source, supplying dc-dc converter(s), dc load(s)s, and/or ac load(s) powered by dc-ac

inverter(s). Informational Note: Direct current power sources include ac-dc converters (rectifiers), bidirectional dc-

ac inverters/converters, photovoltaic systems, wind generators, energy storage systems (including batteries), and

fuel cells. Interconnected Direct Current Distribution Systems are sometimes called DC microgrids. 3. In 712.

Definitions, revise the definition of Primary DC Source as follows: Primary DC Source. A source that supplies the

majority of the dc load in an interconnected dc distribution system. 4. In 712.3 Other Articles, remove the second

sentence and replace it with the following: DC distribution systems that are interconnected through an inverter or

bi-directional converter with ac electric power sources shall comply with Article 705. 5. In 712.4, remove the

following text “direct-current micro grid” and replace it with “interconnected direct current (DC) distribution

system”. 6. In 712.10, remove the term “dc microgrid” and replace it with “interconnected direct current (DC)

distribution system”. 7. In 712.25, remove the term “dc microgrid” and replace it with “interconnected direct

current (DC) distribution system”. 8. In 712.30, remove the term “dc microgrid” and replace it with

“interconnected direct current (DC) distribution system”. 9. In 712.52(A), remove the term “Direct-current

microgrids” and replace it with “interconnected direct current (DC) distribution systems”. 10. In 712.52(B), remove

the term “DC microgrids” and replace it with “interconnected direct current (DC) distribution systems”. 11. In

712.55, remove the term “dc microgrids” and replace it with “interconnected direct current (DC) distribution

systems”. 12. In 712.57, remove the term “DC microgrid” and replace it with “interconnected direct current (DC)

distribution system”. 13. In 712.65(A), remove the term “dc microgrid” and replace it with “interconnected direct

current (DC) distribution system”. 14. In 712.72, remove the term “dc microgrid system(s)” in the first sentence

and replace it with “interconnected direct current (DC) distribution system(s)” and remove the term “dc microgrid”

in the second sentence and replace it with “interconnected direct current (DC) distribution system”.
