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.
