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 = 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.
Second Revision No. 25-NFPA 79-2013 [ Section No. 1.1.1 ] 1.1.1 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.

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 11.5. Using common terminology will assist readers of NFPA 79 with understanding where the Standard starts.

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 9/19/2013 11:27 AM
