Second Revision No. 3617-NFPA 70-2015 [ Section No. 445.11 ]

445.11 Marking.

Each generator shall be provided with a nameplate giving the manufacturer’s name, the rated frequency,the number of phases if of ac, the rating in kilowatts or kilovolt-amperes, the power factor, the normalvolts and amperes corresponding to the rating, and the rated ambient temperature or , and the ratedtemperature rise.

Nameplates or manufacturer's instructions shall provide the following information for all stationarygenerators and portable generators rated more than 15 kW: shall also give the power factor, thesubtransient and transient reactances, the maximum short-circuit current, and the insulation system class.Stationary and portable generators shall be marked to indicate if the generator is protected againstoverload by inherent design, an overcurrent protective relay, circuit breaker, or fuse.

(1) Subtransient, transient, synchronous, and zero sequence reactances

(2) Power rating category

(3) Insulation system class

(4) Indication if the generator is protected against overload by inherent design, an overcurrentprotective relay, circuit breaker, or fuse

(5) Maximum short-circuit current for inverter-based generators, in lieu of the synchronous,subtransient, and transient reactances

Marking shall be provided by the manufacturer to indicate whether or not the generator neutral is bondedto its frame. Where the bonding is modified in the field, additional marking shall be required to indicatewhether the neutral is bonded to the frame.

Committee Statement

CommitteeStatement:

“Power factor” has been relocated to the first paragraph of section 445.11 since it is commonpractice to mark this information on generators of all sizes.

Changes were accepted in the second paragraph to allow certain gen-set information to be placedin the manufacturer’s instructions rather than the nameplate.

“Synchronous” and “zero sequence” have been added to reactances since this information is alsoneeded when modeling electrical systems.

The term “time-rating” was removed during the first draft stage but has been reinserted andrenamed to “power rating category”. This change is necessary to clarify if the gen-set is intendedfor Prime, Continuous, Limited Time Running, or Emergency Standby Power use.

445.20 Ground-Fault Circuit-Interrupter Protection for Receptacles on 15-kW or Smaller PortableGenerators.

All 125-volt, single-phase, 15- and 20-ampere receptacle Receptacle outlets that are a part of a 15-kW orsmaller portable generator either shall have listed ground-fault circuit-interrupter protection (GFCI) forpersonnel integral to the generator or receptacle; or shall not be available for use when the 125/250-voltreceptacle is in use. If the generator does not have a 125/250-volt receptacle, the requirement to disablethe 125-volt, single-phase, 15- and 20-ampere receptacle outlets shall not apply. as indicated in either (A)or (B):

(A) Unbonded (Floating Neutral) Generators.

Unbonded generators with both 125-volt and 125/250-volt receptacle outlets shall have listed GFCIprotection for personnel integral to the generator or receptacle on all 125-volt and 15- and 20-amperereceptacle outlets.

Exception: GFCI protection shall not be required where the 125-volt receptacle outlets(s) is interlockedsuch that it is not available for use when any 125/250-volt receptacle(s) is in use.

(B) Bonded Neutral Generators.

Bonded generators shall be provided with GFCI protection on all 125-volt and 15- and 20-amperereceptacle outlets.

Informational Note: Refer to 590.6(A)(3) for GFCI requirements for 15-kW or smaller portablegenerators used for temporary electric power and lighting.

Exception to (A) and (B): If the generator was manufactured or remanufactured prior to January 1, 2015,listed cord sets or devices incorporating listed ground-fault circuit-interrupter GFCI protection forpersonnel identified for portable use shall be permitted.

Committee Statement

CommitteeStatement:

It is necessary to separate the requirements for both bonded and unbonded generators. Therequirements are different. Clarity is provided in new first level subdivision (A) to clearly requireGFCI's at 125v, 15 and 20 amp only where both 125v and 125/250v receptacles exist on thegenerator. The exception for GFCI's at 125v is maintained for unbonded generators that areinterlocked to disable the 125v receptacles when the 125/250v receptacles are in use. Clarity isprovided in (B) to require that 125v, 15/20 amp receptacles outlets in bonded generators are alwaysrequired to be GFCI protected. The present text misses that and has been corrected. The newinformational note provides clarity by referring the code user to Article 590 for generators used intemporary power under the purview of Article 590. The exception is editorially modified to apply toboth first level subdivisions.

The word "and" needs to be removed from two sentences. The sentences are show below, first as they are in thestandard and then with the unneeded "and" removed. Original: Unbonded generators with both 125-volt and125/250-volt receptacle outlets shall have listed GFCI protection for personnel integral to the generator orreceptacle on all 125-volt and 15- and 20-ampere receptacle outlets. Updated: Unbonded generators with both125-volt and 125/250-volt receptacle outlets shall have listed GFCI protection for personnel integral to thegenerator or receptacle on all 125-volt 15- and 20-ampere receptacle outlets. Original Bonded generators shall beprovided with GFCI protection on all 125-volt and 15- and 20-ampere receptacle outlets. Updated Bondedgenerators shall be provided with GFCI protection on all 125-volt 15- and 20-ampere receptacle outlets.


This revision addresses the fact that GFCI protection is required for bonded 125/250v generators. It allows anexception for generators with interlocking that disables 125 v receptacles when the 125/250v receptacles are in

use.

Little, Linda J.

This revision is primarily editorial and provides significant clarity. The only substantive impact is that on bondedportable generators, the 125-volt receptacles must be GFCI protected. It is imperative to note that small unbondedgenerators that employ only 125-volt receptacles are not required to have GFCI protection. That has been theconcern 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 protectionfor 125-volt, 15/20-amp receptacles, which would directly conflict with the requirements of section 210.8. CMP-13has no justification to specifically permit 125-volt, 15/20-amp receptacles to be applied without GFCI protection onbonded 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 hazardsexist?

Negative with Comment

Czarnecki, Neil A.

The intent of the public inputs on 445.20 were intended to clarify the existing requirements of this section. ThePanel action to create SR 3621 goes well beyond clarification, and creates a new requirement that isunnecessarily restrictive and not technically substantiated.

Degnan, James E.

No substantiation was offered to justify the new text.

Agree because listing is needed to insure products are safe. This provides AHJs and installers assurance that thebatteries installed are suitable for the application.

Little, Linda J.

This new requirement is necessary to ensure safe operation. Recent failures in the Boeing 747 Dreamliner andhover-boards have shown that thermal runaway is a serious fire hazard. The expansion of energy storage intofacilities with occupants mandates that these new battery technologies be tested and certified before installation inaccordance with the NEC.


Czarnecki, Neil A.

The current ANSI standard for storage batteries is battery chemistry independent, and as such, does not take thedifferences in chemistry into consideration in the safety design process. The addition of a listing requirement willtherefore provide limited benefit to the battery consumer and potentially restricts the implementation of newtechnologies and solutions into the electrical industry.

Agree this change is appropriate.

Neeser, Daniel R.

An editorial change by the Correlating Committee or NFPA Staff is suggested. The term “fault-current” inInformational Note No. 2 should be changed to “short-circuit current” as this term is used in 480.7(D)(2). FR 3643changed “short-circuit current” to “fault-current” in 480.7(D)(2) and added Informational Note No. 2, so there wascorrelation with the term. However, SR 3630 changed 480.7(D)(2) from “fault-current” back to “short-circuitcurrent” which is the 2014 NEC term used in this section. However, the SR did not correspondingly change theterm in Informational Note No. 2 to “short-circuit current.” Since this is an Informational Note editorial change, itshould be permissible.

The permanent switching means to connect a portable or temporary alternatesource of power shall comply with the following:

(1) Connection of to the portable or temporary alternate source of power shall not require disabling ofthe emergency system’s normal modification of the permanent system wiring .

(2) It shall be permissible to utilize manual switching to switch from the permanent source of power ordisconnection of the emergency system’s to the portable or temporary alternate source of power,other than by the switching means .

(3) Any transfer Transfer of power between the normal power source and the emergency power sourceshall be in accordance with 700.12. It shall be permissible to utilize manual switching.

(4) The connection point for the portable or temporary alternate source shall be marked with the phaserotation and system bonding requirements.

(5) Mechanical or electrical interlocking shall prevent inadvertent interconnection of power sources.

(6) The switching means shall include an “emergency source disabled” contact for connection to acontact point which shall annunciate at a generator remote annunciator or another facility alarmdata collection point monitoring system to indicate that the permanent emergency source isdisconnected from the emergency system .

It shall be permissible to utilize the switching means for connection of a load bank.

Committee Statement

CommitteeStatement:

The deletion of the last sentence in 700.4(B) in first revision 3617 inadvertently removed therequirement for portable or temporary alternate sources to be available whenever the emergencygenerator is out of service for maintenance or repair.

This requirement is now added into the parent text of first level subdivision 700.3(F) to require aportable or temporary alternate source to be available whenever the emergency generator is out ofservice for maintenance or repair.

The previous requirement was incorrectly located in 700.4(B) Capacity, which limited application tostandby generators used in emergency systems that were also used for selective load pickup, loadshedding, and peak load shaving. The committee expands the requirement to all emergencygenerators where “maintenance or repair” is to be performed. Where an emergency system isrequired, provisions for supplementing the emergency standby generator during maintenance orrepair are necessary.

Editorial revisions are made throughout the requirement to increase clarity and usability.

I agree with the addition of educational facilities with over 300 occupants being added to 700.10(D) as thesefacilities may house occupants that require more egress time than similar sized facilities with a differentoccupancy.

Paulsen, Shawn

The numbering layout is a bit confusing when reading the entire Rule. The Rule states that (D)(1)through (D)(3)isto be followed and directly underneath there are 4 requirements. I realize these are not the requirements to befollowed and suggest these 4 additional requirements possibly be lettered in place of numbering.


Degnan, James E.

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 whichcannot be accounted for by an electrical code. Listing these items in NFPA 70 has the potential to lead to conflictswith building codes, leaving AHJs in quandary. Instead of expanded, this paragraph should be removed, otherwiseit will subsequently need to add other occupancy types to the list, with all of their corresponding building codedetails.


After much consideration and research I have not been able to locate where the absence of this requirement hasresulted in undo hardship or injury to the building or inhabitants. The provision for automatic fire sprinklers isalready mandated in these structures as noted in the building and life safety codes, which will provide not only lifesafety protection but property protection as well. The archived materials and fire reports I have read state thesprinkler systems engaged fires within their respective design times. I recently interviewed a Institutional UseConstruction Manager/Inspector, in preparation for the voting on this revision, and I was informed they prepare forand practice fire evacuations for their facility and were against the added cost this proposal would add toadditional buildings in their campus style installation. After researching the NFPA archives for additional fire data Ifeel I need to vote negative without any quantitative or empirical technical substantiation.

The term "not capable of self preservation" needs to be defined. An individual could enter a health careoccupancy being capable and for a portion of the stay not being capable of self preservation.

Committee Statement

CommitteeStatement:

The action taken by the committee on the Second Revision to 700.10(D) to expand the fireprotection requirements in 700.10(D) requires that correlation occur in section 700.12.

This revision adds “health care occupancies where persons are not capable of self preservationand educational occupancies with more than 300 occupants” to correlate with the revisions in700.10(D).

This revision does not represent new material. Public input 1246 sought the revisions seen in theFR to modify 700.10(D). In the first revision stage public input 1246 was resolved. If a first revisionhad occurred in 700.10(D) as suggested in public comment 1246, a first revision to correlate in700.12 would have been necessary.

I agree with the addition of educational facilities with over 300 occupants being added to 700.10(D) as thesefacilities may house occupants that require more egress time than similar sized facilities with a differentoccupancy.


I could support this proposal as it does reference the inclusion/exception for a sprinkler system, which should bean automatic sprinkler system.


Paulsen, Shawn

The term "not capable of self preservation" needs to be defined. An individual could enter a health careoccupancy being capable and for a portion of the stay not being capable of self preservation. For example would aDentist office be considered. As written I believe this term will lead to inconsistent application of the Rule.

There is no evidence to support that 2" of concrete provides a 2 hour rating. In fact there is evidence that impliesthe contrary and that it would require 4" or more of concrete encasement to provide a 2 hour fire rating. I wouldagree with this revision if it were limited to the application of slab on grade (SOG) cases. Since it is not specific toSOG that then ceilings and walls would be allowed as protection for conductors. This is an area that needs labtesting to be performed to determine temperatures that conductors are exposed too under various levels ofconcrete thicknesses as well as different concrete mixes. The testing should include conductors installed ongrade, walls, and ceiling/floors.

Second Revision No. 3627-NFPA 70-2015 [ Article 712 ]

Article 712 Direct Current Microgrids

Part I. General

712.1 Scope.

This article applies to direct current microgrids.

712.2 Definitions.

Direct Current Microgrid (DC Microgrid).

A direct current microgrid is a power distribution system consisting of one or more than oneinterconnected dc power sources , supplying dc-dc converters (s) , dc loads (s) , and/or ac loads (s)powered by dc-ac inverters (s) . A dc microgrid is typically not directly connected to an ac primary sourceof electricity, but some dc microgrids interconnect via one or more dc-ac bidirectional converters or dc–acinverters.

Informational Note: Direct current power sources include ac-dc converters (rectifiers), bidirectionaldc-ac inverters/converters, photovoltaic systems, wind generators, energy storage systems(including batteries), and fuel cells.

Grounded Two-Wire DC System

A two-wire dc power system that has a direct solid connection or reference-ground between one of thecurrent carrying conductors and the equipment grounding system.

Grounded Three-Wire DC System.

A dc power system with a solid connection or reference-ground between the center point of a bipolar dcpower source and the equipment grounding system.

Nominal Voltage.

A nominal value assigned to a circuit or system for the purpose of conveniently designating its dc voltageclass (e.g., 24 volts dc, 190/380 volts dc, 380 volts dc) .

Informational Note: The actual voltage at which a circuit operates can vary from the nominalvoltage within a range that permits satisfactory operation of equipment.

Reference-Grounded DC System.

A microgrid system that is not solidly grounded but has a low-impedance resistance electrical referencethat maintains voltage to ground in normal operation. In the faulted-state, the system becomesungrounded or high-impedance grounded in order to limit fault current.

Resistively Grounded.

A dc power system with a high-impedance resistance connection between the current carryingconductors and the equipment grounding system.

Primary DC Source.

A dc power source that supplies the majority of the dc load in a dc microgrid.

Ungrounded DC System.

A dc power system that has no direct or resistive connection between the current carrying conductors andthe equipment grounding system.

712.3 Other Articles.

Wherever the requirements of other articles of this Code and Article 712 differ, the requirements of Article712 shall apply. DC microgrids interconnected through an inverter or bi-directional converter with acelectric power production sources shall comply with Article 705.

Committee Statement

CommitteeStatement:

The defined terms “Grounded Two-Wire DC System”, “Grounded Three-Wire DC System,”“Nominal Voltage”, “Reference-Grounded DC System”, “Resistively Grounded”, “Primary DCSource”, “Ungrounded DC System” are editorially modified for clarity, usability and compliance withthe NEC style manual.

The definition of “Direct Current Microgrid” is modified to clarify that more than one interconnectedsource is required.

The last sentence in the defined term, “Reference-Grounded DC System” is deleted because it is arequirement.

712.4 is modified for clarity.

Editorial corrections are made and an Informational Note is added to 712.30 for clarity and usability.

712.34 is modified for clarity. The reference to 690.13(A) is deleted as there are many potentialsources.

712.37 is modified for clarity. The listing and marking requirement is added to ensure that directionalcurrent devices are approved for the intended use.

Section 712.38 was deleted. The requirements in this section were intended to mirror theanti-islanding requirements for interconnected ac systems, in that distributed sources should notback-feed a de-energized utility grid. As there are presently no dc utility services, 712.38 only addsconfusion and is unlikely to be relevant for many years until dc utility distribution systems are againimplemented.

712.40 is deleted. First level subdivision (A) was just a reference to identification of DC conductorsand the requirements in 210 and 215 apply as per section 90.3. First level subdivision (B) is deletedbecause it is referenced in 712.52.

712.52 is editorially revised to add first level subdivision titles.

In section 712.55, the term “ground fault protection” was changed to “ground fault detection.” Theremainder of the section was editorially revised.

712.57 for arc fault protection of systems was modified to reference other requirements for arc faultprotection in the NEC.

Part numbers were editorially revised.

Section 712.62 was modified from panelboards to distribution equipment and conductors.

Section 712.65, Panelboards, is deleted because it was duplicated.

Section 712.65, Available DC Fault Current, is modified for clarity and to specifically address “shortcircuit current” and to include the date of the marking.

The title of Part VII (now Part VI) is revised to “Protection” for clarity.

Section 712.70 is revised for clarity and usability.

Section 712.72 is modified for clarity to specifically address “short circuit current”.

Section 712.80 is revised for clarity and usability.

We are voting affirmative on SR 3627 with the following comment: It is imperative that the title of this Article isreconsidered, and if changed, editorial revisions made throughout. The use of the term “microgrid” may causeserious confusion in the industry. The term “microgrid” infers utility owned conductors and equipment. Thesystems addressed in this Article should be addressed by a term that more appropriately captures the systemitself. This Article could be retitled as “Interconnected Direct Current (DC) Distribution Systems.” The NECCorrelating Committee (CC) is well aware of previous issues created in 90.2 with references to the NESC ininformational notes, and the CC formed a task group to resolve those issues. The CC must understand thesignificance of this issue and the serious concerns presented by the electrical utilities represented in this revisionstage with respect to the use of the term “microgrid.” We, the NEC community, would take serious exception if theNational Electrical Safety Code (NESC) would begin to use and apply the term “premises wiring” to utility ownedconductors and systems. This Article and the work within are important and should be in the 2017 NEC, which iswhy we are voting affirmative. The NEC CC should seriously consider removal of the term “microgrid.”



The term “Microgrid” is a jargon and non-specific term. The NEC process consistently encourages usingterminology that provides clarity. The term “Interconnected Direct Current (DC) Distribution System” provides thisclarity. 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 typemicrogrid systems are still in the R&D phase and still in development in other standards committees outside theNFPA. Therefore, as this technology continues to emerge, we need to ensure that the lines do not become blurredbetween the two systems. We are mixing two different systems, therefore keeping different terms in the NEC willbest serve the industry. To move forward with the technology of an interconnected DC system and revise thejargon 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) DistributionSystems. 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. Aninterconnected direct current (DC) distribution system is a power distribution system consisting of more than oneparallel connected dc power source, supplying dc-dc converter(s), dc load(s)s, and/or ac load(s) powered by dc-acinverter(s). Informational Note: Direct current power sources include ac-dc converters (rectifiers), bidirectionaldc-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 themajority of the dc load in an interconnected dc distribution system. 4. In 712.3 Other Articles, remove the secondsentence and replace it with the following: DC distribution systems that are interconnected through an inverter orbi-directional converter with ac electric power sources shall comply with Article 705. 5. In 712.4, remove thefollowing 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) distributionsystem”. 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” andreplace it with “interconnected direct current (DC) distribution systems”. 11. In 712.55, remove the term “dcmicrogrids” and replace it with “interconnected direct current (DC) distribution systems”. 12. In 712.57, remove theterm “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. In712.72, remove the term “dc microgrid system(s)” in the first sentence and replace it with “interconnected directcurrent (DC) distribution system(s)” and remove the term “dc microgrid” in the second sentence and replace it with“interconnected direct current (DC) distribution system”.
