    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 3 has voted to accept a Code change submitted by Merton W. Bunker, Jr., U.S. Department of State, (Log #1173 NEC-P03). Bunker recommended adding a new item to 725.3 to read as follows: "(H) Raceways Exposed to Different Temperatures. Installations shall comply with 300.7(A)." He notes that condensation often forms in conduit exposed to non-conditioned and condition space, and this change will bring the requirements of 300.7(A) into Art. 725.

    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.

    Code Q&A
    By Mike Holt
    Q. We have a heat tape system installed on a metal roof. The heat tape has arced against the metal before, and we are concerned we will burn the place to the ground. Someone told us to use a GFCI on the circuit, and someone else told us not to. Does the NEC offer any guidance here?

    Code News Update
    South Carolina Building Council Contemplates Code Version
    Now that South Carolina has adopted the 2008 NEC, as of July 1, 2009, a question recently arose at the South Carolina Building Codes Council meeting in late August, concerning which edition of the Code (2005 or 2008) should be used as a reference for the 2006 International Residential Code (IRC).

    According to a notice posted on its Web site, the question addressed by the Building Codes Council was "based on the language of the preamble for Chapter 33 of the IRC, which states the requirements of the chapter are based on the 2005 NEC."

    After reviewing the language of the preamble — along with the applicable state law — the notice also indicates that council members concluded the 2008 NEC is the current electrical code; therefore, it should be "duly adopted and implemented." In addition, it agreed that two editions of the same code cannot be valid at the same time. The Council also drew the following conclusions:

    • Construction of single- and two-family residences, including all related systems, must be in compliance with the IRC; and
    • If a specific issue is not addressed in the electrical section of the IRC, the 2008 NEC may be used.
