    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 9 has voted to accept a Code change submitted by Mike Theisen, St. Cloud, Minn., (Log #1703 NEC-P09). Theisen recommended removing a reference to Part II in 408.30 to help clarify that the rating in question is the feeder or service, not a branch circuit. He notes that Part II is referenced in Part III of Art. 220, so no requirements will be lost.

    The document is open for public review and comment through October 23, 2009. You can download an electronic version of the report via the NFPA Web site.

    All interested parties are urged to read this report and submit their comments on the forms provided in the report. Each comment received on or before the closing date of the comment period will be considered and acted upon by the NEC Code Committee. The results of the committee action 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.
