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 4 has
voted
to accept a Code change submitted by the Michael J. Johnston, National
Electrical Contractors Association (Log #562 NEC-P04). The
recommendation calls for revising the text of 230.54(A) and (B) to read
as follows:
"(A) Service Head. Service raceways shall be equipped with a service
head at the point of connection to service-drop conductors. The service
head shall comply with the requirement for fittings in 314.15.
be listed for use in wet locations."
"(B) Service Cable Equipped with Service Head or Gooseneck. Service
cables shall be equipped with a service head. The service head shall
comply with the requirement for fittings in 314.15. be listed
for use in wet locations."
As noted in the substantiation summary, this change will address the
usability of the Code. As noted by the submitter, "The requirement
should appear clearly within these two rules for service weatherheads
rather than needing to refer to another rule to find what is required."
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.
