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) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (Sample calculation: 20 members eligible to vote 2 = 10 + 1 = 11) (2) Example for Affirmative 2 / 3 : Assuming there are 20 vote eligible committee members and 1 member did not return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligble to vote 1 not returned 2 abstentions = 17 x 0.66 = 11.22 = 12 ) As always please feel free to contact me if you have any questions.

of 44 4/15/2015 1:06 PM First Revision No. 3002-NFPA 70-2015 [ New Section after 409.22 ] 409.23 Available Fault Current. When an industrial control panel is required to be marked with a short circuit current rating in accordance with 409.110(4), the available short circuit current at the industrial control panel and the date the short circuit current calculation was performed shall be documented and made available to those authorized to inspect the installation. Submitter Information Verification Submitter Full Name: CMP 11 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Thu Jan 15 10:30:50 EST 2015 Committee Statement Committee Statement: This change provides much needed information to aid the electrical inspector when enforcing 409.22. It will help the inspector ensure that the industrial control panel is installed within its short-circuit current rating. Response Message: Public Input No. 4421-NFPA 70-2014 [New Section after 409.22] Public Input No. 4733-NFPA 70-2014 [New Section after 409.22] Ballot Results This item has passed ballot 15 Eligible Voters 0 Not Returned 12 Affirmative All 2 Affirmative with Comments 1 Negative with Comments 0 Abstention Affirmative All Bas, Luis M.

Affirmative with Comment Folz, Stanley J. In addition to the AHJ this information should also be made available to anyone servicing the control panel. Powell, Charles L. For consistency with code language in 110.9, 440.10, etc. and the section title, I suggest the following wording - 409.23 Available Fault Current. When an industrial control panel is required to be marked with a short circuit current rating in accordance with 409.110(4), the available fault current at the industrial control panel and the date the fault current calculation was performed shall be documented and made available to those authorized to inspect the installation. Negative with Comment Cole, Terry D. There are numerous reasons to oppose requiring additional field labeling of equipment that is located downstream of the main service: 1. Article 110.9 and 110.10 Interrupting Rating already requires that equipment intended to interrupt current at fault levels shall have an interrupting rating sufficient for the current that is available. 2. How far down stream is this requirement going to be carried? It is already required by Article 110.24 for the service and Article 110.9 and 110.10 state that the equipment must be applied correctly. The code seems to be repeating itself if we add this change. Further, the exception found in 110.24(A) and (B) excludes industry. This would seem to be a correlation issue since the majority of this type of equipment is found in industrial environments. 3. The argument has been made that this would be easier for the inspectors to verify the right equipment is being used. Jurisdictions have the right to require one line diagrams that would require this information for enforcement purposes. 4. The liability to the installer is a major concern because they do not have the ability to control modifications after the initial installation. In a potential lawsuit fingers would be pointed at the installer first. If the owner denies making any modifications or does not have knowledge of any modifications, such as maintenance making changes that were not documented or maintenance people that made changes and left their job, then the installer is left holding the responsibility. This would be true whether the date of the installation is recorded or not. For these reasons this proposal should be resolved. Page 2 of 46

of 44 4/15/2015 1:06 PM First Revision No. 3001-NFPA 70-2015 [ Section No. 409.110 ] 409.110 Marking. An industrial control panel shall be marked with the following information that is plainly visible after installation: (1) Manufacturer's name, trademark, or other descriptive marking by which the organization responsible for the product can be identified. (2) Supply voltage, number of phases, frequency, and full-load current for each incoming supply circuit. (3) Industrial control panels supplied by more than one power electrical source such that more than one disconnecting means is required to disconnect all power circuits within the control panel shall be marked to indicate that more than one disconnecting means is required to de-energize the equipment. The location of the means necessary to disconnect all circuits 50-volts and over shall be documented and available. (4) Short-circuit current rating of the industrial control panel based on one of the following: a. Short-circuit current rating of a listed and labeled assembly b. Short-circuit current rating established utilizing an approved method Informational Note: ANSI/UL 508A, Standard for Industrial Control Panels, Supplement SB, is an example of an approved method. Exception to (4): Short-circuit current rating markings are not required for industrial control panels containing only control circuit components. (5) If the industrial control panel is intended as service equipment, it shall be marked to identify it as being suitable for use as service equipment. (6) Electrical wiring diagram or the identification number of a separate electrical wiring diagram or a designation referenced in a separate wiring diagram. (7) An enclosure type number shall be marked on the industrial control panel enclosure. Submitter Information Verification Submitter Full Name: CMP 11 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Thu Jan 15 09:36:15 EST 2015 Committee Statement Committee Statement: This change addresses a gap in worker safety for voltages over 50V. The current wording warns a service technician that multiple sources of power are present, but provides no guidance in how to locate those sources of power. If an emergency arises Page 3 of 46

of 44 4/15/2015 1:06 PM which necessitates disconnection of power but the technician is unfamiliar with the facility there could be a risk to both personnel and property. The error in the Informational Note has been corrected. UL 508A is the standard for industrial control panels that includes Supplement SB. UL 508 is the standard for industrial control equipment.

Other than for motors built for low speeds (less than 1200 RPM) or high torques, and for multispeed motors, the values given in Table 430.247, Table 430.248, Table 430.249, and Table 430.250 shall be used to determine the ampacity of conductors or ampere ratings of switches, branch-circuit short-circuit and ground-fault protection, instead of the actual current rating marked on the motor nameplate. Where a motor is marked in amperes, but not horsepower, the horsepower rating shall be assumed to be that corresponding to the value given in Table 430.247, Table 430.248, Table 430.249, and Table 430.250, interpolated if necessary. Motors built for low speeds (less than 1200 RPM) or high torques may have higher full-load currents, and multispeed motors will have full-load current varying with speed, in which case the nameplate current ratings shall be used. Exception No. 1: Multispeed motors shall be in accordance with 430.22(B) 430.22(B)430.22(B) 430.22(A) and 430.52. Exception No. 2: For equipment that employs a shaded-pole or permanent-split capacitor-type fan or blower motor that is marked with the motor type, the full load current for such motor marked on the nameplate of the equipment in which the fan or blower motor is employed shall be used instead of the horsepower rating to determine the ampacity or rating of the disconnecting means, the branch-circuit conductors, the controller, the branch-circuit short-circuit and ground-fault protection, and the separate overload protection. This marking on the equipment nameplate shall not be less than the current marked on the fan or blower motor nameplate. Exception No. 3: For a listed motor-operated appliance that is marked with both motor horsepower and full-load current, the motor full-load current marked on the nameplate of the appliance shall be used instead of the horsepower rating on the appliance nameplate to determine the ampacity or rating of the disconnecting means, the branch-circuit conductors, the controller, the branch-circuit short-circuit and ground-fault protection, and any separate overload protection.

Affirmative with Comment Folz, Stanley J. In addition to the AHJ this information should also be made available to anyone servicing the MCC. Powell, Charles L. For consistency with code language in 110.9, 440.10, etc. and the section title, I suggest the following wording - 430.99 Available Fault Current. The available fault current at the motor control center and the date the fault current calculation was performed shall be documented and made available to those authorized to inspect the installation. Negative with Comment Cole, Terry D. There are numerous reasons to oppose requiring additional field labeling of equipment that is located downstream of the main service: 1. Article 110.9 and 110.10 Interrupting Rating already requires that equipment intended to interrupt current at fault levels shall have an interrupting rating sufficient for the current that is available. 2. How far down stream is this requirement going to be carried? It is already required by Article 110.24 for the service and Article 110.9 and 110.10 state that the equipment must be applied correctly. The code seems to be repeating itself if we add this change. Further, the exception found in 110.24(A) and (B) excludes industry. This would seem to be a correlation issue since the majority of this type of equipment is found in industrial environments. 3. The argument has been made that this would be easier for the inspectors to verify the right equipment is being used. Jurisdictions have the right to require one line diagrams that would require this information for enforcement purposes. 4. The liability to the installer is a major concern because they do not have the ability to control modifications after the initial installation. In a potential lawsuit fingers would be pointed at the installer first. If the owner denies making any modifications or does not have knowledge of any modifications, such as maintenance making changes that were not documented or maintenance people that made changes and left their job, then the installer is left holding the responsibility. This would be true whether the date of the installation is recorded or not. For these reasons this proposal should be resolved. Page 20 of 46

Rather than ban the use of EMT or non threaded conduit on rooftops, as suggested by PI 1800, adding this requirement satisfactorily addresses the problem. The Panel does not agree with the exception for industrial installations with qualified persons as it does not assure the conduit on the roof will be inspected or observed on a regular basis any more than on a commercial roof.

Ockuly, George J. Powell, Charles L. Smith, III, Arthur J. Widup, Ron Negative with Comment Thompson, John M. All UL certified metallic conduit, including EMT, is evaluated for its ability to bond the conduit to the connecting fittings thereby ensuring the bonding and grounding of the equipment. The testing in the Standards goes beyond electrical tests and includes rigorous mechanical stress tests. This Panel Action does not address the root cause that is driving this First Revision, and that is the maintenance of all installed equipment regardless of type and location. The forces needed to dislocate conduit from the conduit- fitting is equally likely to dislocate the additional grounding conductor. Adding additional grounding and bonding, a belts and suspenders approach, is allowed in the Code, but will not address what is reported to be poor or ineffective maintenance practices. Wright, James R. The NEC is a minimum standard and does not prevent the use of an equipment grounding conductor in metallic raceways systems. There was inadequate substantiation provided to require the use of an equipment grounding conductor in outdoor portions of metallic raceway systems that use non-threaded fittings. Since the NEC FR reports are often used for research and training, it is problematic that the Panel Statement is inaccurate. The statement includes the following: Non-threaded conduit systems on rooftops supplying HVACR equipment are subject to movement and damage that results in separation of non-threaded conduit or tubing resulting in loss of equipment grounding unless a wire type equipment ground is provided. That is a blanket statement that infers that this situation is a standard occurrence. A PI on which this FR is based PI 4312 refers to those rare instances that the wiring system installation has been damaged and the wire-type EGC is not installed. There is no assurance that the wire type equipment grounding conductor could not also be subject to damage. Page 30 of 46

Motor controllers of multimotor and combination-load equipment shall not be installed where the available fault current exceeds its short-circuit current rating as marked in accordance with 440.4(B). (B) Documentation. When motor controllers or industrial control panels of multimotor and combination load equipment are required to be marked with a short circuit current rating, the available short circuit current and the date the short circuit current calculation was performed shall be documented and made available to those authorized to inspect the installation. Submitter Information Verification Submitter Full Name: CMP 11 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Thu Jan 15 12:37:31 EST 2015 Committee Statement Committee Statement: Section 440.4(B) requires that the equipment short-circuit current rating be marked on certain HVAC equipment. This new section specifically requires that the marked HVAC equipment not be installed where the available short-circuit current exceeds the marked short-circuit current rating. This requirement is similar to 670.5 (industrial machinery) and 409.22 (industrial control panels). Inspectors are having an extremely difficult time enforcing proper short-circuit current ratings of HVACR equipment because there is typically no information on the job site as to the available fault current at the HVACR equipment. If documentation of the available fault current were provided to the electrical inspector, it would be much easier for the inspector to assure that the equipment was being properly protected. This change provides that fault current information to the AHJ. Per Exception #3 to 440.4(B) this new requirement does not apply to one and two family dwellings or cord-and-attachment -plug connected equipment.
