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 James W. Carpenter,
International Association of Electrical Inspectors (Log #2806 NEC-P12).
The recommendation calls for deleting Sec. 665.3, which currently reads
as follows:
"Other Articles. Unless specifically amended by this
article, wiring from the source of power to the heating equipment shall
comply with Chapters 1 through 4."
As noted in the substantiation summary, Section 90.3 indicates
Chapters 1 - 4 apply generally, and Chapters 5, 6, and 7 supplement or
modify the general requirements. The text in 665.3 repeats the
requirement previously expressed in 90.3 and serves no additional
purpose. It should also be noted that other "Special" articles do not
include a similar requirement. Inconsistent application of the text
could also lead to confusion.
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.
