There are two criteria necessary for each Second 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 = = 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 = = 12 ) As always please feel free to contact me if you have any questions.

2 Second Revision No. 25-NFPA [ Section No ] The provisions of this standard shall apply to the electrical/electronic equipment, apparatus, or systems of industrial machines operating from a nominal voltage of 600 volts or less, and commencing at the point of connection of the supply circuit conductors to the electrical equipment of the machine. Submitter Information Verification Submitter Full Name: [ Not Specified ] Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Wed Jul 10 10:28:54 EDT 2013 Committee Statement Committee Statement: Response Message: The TC understands document scopes are the jurisdiction of the NEC CC and offers a revision of the paragraph in the interest of clarifying the scope of NFPA 79. Revising the paragraph as offered will align the text of this section with existing requirements in the Standard such as the main disconnecting means requirements in Chapter 5 and with the new text relative to working spaces in Using common terminology will assist readers of NFPA 79 with understanding where the Standard starts.

The rating of a time-delay Class CC fuse and non time-delay Class CC, J, CF, or T fuse shall be permitted to be increased but shall in no case exceed 400 percent of the full-load current. 2 Types of starting duty are as follows: (a) AC-2: All light-starting duty motors, including slip-ring motors; starting, switching off. (b) AC-3: All medium starting duty motors including squirrel-cage motors; starting, switching off while running, occasional inching, jogging, or plugging but not to exceed 5 operations per minute or 10 operations per 10 minutes and all wye-delta and two-step autotransformer starting motors. (c) AC-4: All heavy starting duty motors including squirrel-cage motors; starting, plugging, inching, jogging. 3 Unless a motor controller is listed for use with RK-5 fuses, Class RK-5 fuses shall be used only with NEMA-rated motor controllers. 4 Instantaneous trip circuit breakers shall be permitted to be used only if they comply with all of the following: (a) They are adjustable. (b) Part of a combination controller has motor-running protection and also short-circuit and ground-fault protection in each conductor. (c) The combination is especially identified for use. (d) It is installed per any instructions included in its listing or labeling. (e) They are limited to single motor applications, circuit breakers with adjustable trip settings shall be set at the controller manufacturer's recommendation, but not greater than 1300 percent of the motor full-load current.

Affirmative with Comment Hilbert, Mark R. Continue to delete the language allowing the structural components of the machine to serve as the equipment grounding conductor. Although I agree there are structural members of a machine that could serve as an equipment grounding conductor, allowing the machine structural members to serve as an equipment grounding conductor can present a significant challenge for the electrical inspector. Determining that all the machine structural members that could possibly be involved in an equipment grounding pathway would be equal to a number times the cross-sectional area of a copper conductor etc., would be difficult at best. Additionally, many machines are assembled in sections and the sections are painted by the OEM and/or by the user before installation at the plant. 4 of 122 9/19/ :27 AM
