Pending Code Change Item for 2011
As noted in the NEC Committee Report on
Proposals, 2010 Annual Revision Cycle, Code-Making Panel 3 has
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
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
into Art. 725.

Q. We have a heat tape system installed on a
metal roof. The heat tape has arced against the metal before, and we
concerned we will burn the place to the ground. Someone told us to use
GFCI on the circuit, and someone else told us not to. Does the NEC
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
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.
