Code News Update
Two New NEC Adoptions
The city of Dallas and the state of Georgia recently
adopted the 2005 National Electrical Code as their basic wiring
standard with amendments.
The city of Dallas amendments, which were recommended by the North
Texas Council of Governments, include:
- a new exception to 230.71(A), which allows for more than six
disconnects to be grouped at one location.
- a new exception to 300.11, which provides limited support of
raceways and cables by ceiling grid support wire.
- a change to 310.15(B)(6), which (according to the council) provides
a more reasonable margin of safety for dwelling service and feeder
conductor allowable ampacities.
- a change to 500.8(A)(1), which eliminates some text deemed
with the definition of "identified" in Chapter 1.
The state of Georgia amendments, which were recommended by the
Codes Advisory Committee, include:
Both adoptions had an effective date of January 1, 2006.
- a change to 210.8(B), which requires GFCI protection for
located within 6 feet of a sink or basin, excluding those listed in
- a change in the wording of 210.12(B).
