    Change Proposals
    Pending Code Change Item for 2011 NEC
    As noted in the NEC Committee Report on Proposals, 2010 Annual Revision Cycle, Code-Making Panel 12 has voted to accept a Code change submitted by Rodney Belisle, NIETC (Log #250 NEC-P12). The recommendation calls for revising the text of Sec. 645.17 as follows:

    "Power distribution units that are used for information technology equipment shall be permitted to have multiple panelboards within a single cabinet, provided that each panelboard has no more than 42 overcurrent devices and the power distribution unit is utilization equipment listed for information technology application."

    As noted in the submitter's substantiation summary, this was a change that was implemented into Art. 408 during the 2008 revision cycle with removal of 408.35. Unfortunately, Art. 645 was unintentionally overlooked during the correlation process.

    You can download an electronic version of the report via the NFPA Web site.

    Although the comment period is now closed, the results of the committee action on all submitted comments will be published in the NEC Committee Report on Comments, which will be made available to all who request it. The Report on Comments mail date is scheduled for March 29, 2010.
