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 17 has
voted to accept a Code change submitted by James S. Conrad, Tyco
Thermal
Controls, (Log #2732 NEC-P17). Conrad recommended deleting the second
half of the only sentence in this requirement. The revised text would
appear as follows:"Ground-fault protection of equipment shall be
provided for fixed outdoor electric deicing and snow-melting
equipment, except for equipment that employs mineral-insulated,
metal-sheathed cable embedded in a noncombustible medium." He notes
that mineral insulated cables employ different types of metal sheaths,
not all of which are suitable as ground fault return paths. He also
notes this revision would harmonize the NEC with the Canadian
Electrical
Code, which requires ground-fault protection, not only for embedded
electric deicing and snow-melting cables, but for all electric heating
cables, regardless of their application.
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.
