Exhibit "A"
RESOLUTION IN SUPPORT OF ELECTRICAL CODE UNIFORMITY AND
ENDORSEMENT OF THE NATIONAL ELECTRICAL CODE - 1996 EDITION
WHEREAS, the North Central Texas Council of Governments is established to assist local
govemments in planning for common needs, cooperating for mutual benefit, and coordinating for
sound regional development; and
WHEREAS, the North Central Texas Council of Governments has been active for the last
twenty-nine years in promoting construction code uniformity in the region; and
WHEREAS, code uniformity has been documented to lead to a decrease in confusion and
delays to builders, developers and architects; a decrease in costs to municipalities in the
development of codes; and, ultimately, a decrease in construction costs to consumers; and
WHEREAS, the National Electrical Code is published every three years with the 1993
Edition having been previously endorsed by the Executive Board; and
WHEREAS, the Regional Codes Coordinating Committee has reviewed the National
Electrical Code - 1996 Edition and recommends its endorsement with regional amendments.
NOW, THEREFORE, BE IT HEREBY RESOLVED:
SECTION 1
SECTION 2
SECTION 3
SECTION 4
SECTION 5
That the Executive Board firmly supports the current activities in
promoting electrical code uniformity in the North Central Texas
region.
That the Executive Board endorses the National Electrical Code -
1996 Edition published by the National Fire Protection Association
and recommends its adoption by all cities in the North Central
Texas region.
That the Executive Board endorses the attached regional
amendments to the National Electrical Code - 1996 Edition and
recommends their adoption by all cities in the North Central Texas
region.
That the Executive Board encourages all cities to adopt the
National Electrical Code - 1996 Edition with no local amendments
other than the regionally recommended amendments with an
effective date of January 31, 1997.
That this motion shall be in effect immediately upon its adoption.

I hereby certify that this resolution was adopted by the Executive Board of the North Central Texas
Council of Governments on September 19,1996.
1996 NATIONAL ELECTRICAL CODE

)lelrional Amendment~ amUnternretations*
REGIONAL AMENDMENTS
230-2. Number of Services.
(a) Number. A building or other structure shall be served by only one service.
Exception No.1: For fire pumps... {text unchanged} ...considered to be one service lateral.
ExceDtion No. 8: In sUDDlyin1! electrical service to multifamily dwellin1!s. two or more laterals
or overhead service droDs shall be Dermitted to a buildin1! when all of the followin1! conditions are
~
a. The buildin1! hei1!ht is limited to three stories.
b. The buildin1! has six or more individual1!an1! meters and all meters are 1!rouDed at the
same location.
c. Each lateral or overhead service droD ori1!inates from the same Doint of service.
REASON FOR CHANGE: This is currently the accepted installation practice of the region. No
noteworthy complaints have surfaced. It is more reasonable than the current NEC requirements.
It allows more than six disconnects grouped at one location, without having to divide the structure
into multiple buildings by using area separation walls. This also allows designers more flexibility in
the placement of electrical meters and main service disconnects.
230-71. Maximum Number of Disconnects.
(a) General. The service disconnecting means for each service permitted by Section 230-2, or
for each set of service-entrance conductors permitted by Section 230-40, Exception No.1, shall
consist of not more than six switches or six circuit breakers mounted in a single enclosure, in a
group of separate enclosures, or in or on a switchboard. There shall be no more than six
disconnects per service grouped in anyone location.
ExceDtion No.1: Multi-occuDant Buildinl!s. Individual service disconnectinl! means is limited
to six for each occUDant. The number of individual disconnects at one location may exceed six.
Exception No.2: For the purpose of this section, disconnecting means used solely for the
control circuit of the ground fault protection system, installed as pan of the listed equipment, shall
not be considered a service disconnecting means.
REASON FOR CHANGE: The same reasoning as for multi-family dwellings in Section 230-2
except now it is being applied to multi-occupant buildings.
*NOTE: Underlininl! indicates new words and p~es to be added to the 1996 National
Electrical Code. Strilc-eeat5 indicate existing words and phrases to be deleted.

Exhibit "e"
2SG-81. Grounding Electrode System. If available on the premises at each building 0r sttucture
served, each item (a) through (d) below, and any made electrodes... {text unchanged} ...interconnect
electrodes that are part of the grounding electrode system.
Exception No.2: In industrial and commercial buildings where conditions of maintenance
and supervision ensure that only qualified persons will service the installation and the entire length
of the interior metal water pipe that is being used for the conductor is exposed.
Where a metal underl!I'Ound water oipe. as described in item (at is not oresent. a method of
grounding as soecified in (b) through (d) below shall be used.
(FPN): See Section 547-8 for special grounding and bonding requirements for agriculture buildings.
REASON FOR CHANGE: Sometimes metal underground water pipe is not available for use as a
grounding electrode system. Therefore, to provide a more positive approach for grounding
electrical premise systems for safety, a method as specified in (b), (c), or (d) shall be used. This
will eliminate the need to depend solely on a driven rod or pipe as specified in Section 250-83.
300-11. Securing and Supporting.
[Delete Section 300-11 in the National Electrical Code - 1996 Edition and
replace with Section 300-11 from the National Electrical Code - 1993 Edition]
REASON FOR CHANGE: The requirements of Section 300-11 in the 1996 National Electrical
Code are very cost prohibitive. The section is currently under review by NEC Code Panel 3 for
possible revision.
310-16 through 310-19 - Allowable Ampacity Tables.
Notes to Ampacity Tables of 0 to 2000 Volts
3. 120/240 Volts, 3-Wire, Single-Phase Dwelling Services and Feeders. For dwelling units,
conductors, as listed below, shall be... {text unchanged} ...conductors. The grounded conductor shall
be pennitted to be smaller than the ungrounded conductors, provided the requirements of Sections
215-2,220-22, and 230-42 are met. This Note to Tables 310-16 throueh 310-19 shall not be used
in coni unction with Section 220-30.
REASON FOR CHANGE: To provide a more reasonable margin of safety for dwelling service
and feeder conductor allowable ampacities.

September 19, 1996
336-5. Uses Not Permitted.
(a) Types NM, NMC, and NMS. Types NM, NMC, and NMS cables shall not be used:
(1) In any dwelling or structure exceeding three floors above grade.
For the purpose of this article, the first floor of a.. {text unchanged}... vehicle parking, storage,
or similar use shall be permitted.
Exception No.1: An additional level shall be permitted where the renovation of attic, vehicle
parking, or storage space creates a habitable floor level in an existing one-famiIy dwelling.
ExceDtion No.2: An additional level shall be Dermitted in dwellings where the entire structure
is Drotected throughout bv an aDDroved automatic sDrinkler system.
(2) As service-entrance cable.
(10) In non-residential metal frame structures.
REASON FOR CHANGE: To allow a reasonable expansion for NM cable use in dwelling
occupancies, while somewhat limiting the use of NM cable in occupancies where it is more
vulnerable to physical damage and where use is somewhat limited by the NEC and building
codes. This allows nonmetallic sheathed cable as a wiring method in four story single or
multifamily dwellings provided they are fully sprinkled throughout the entire building. It allows
designers to be more cost effective in their designs of wiring methods.
REGIONAL INTERPRETATIONS

[This specification may apply to restaurants regarding new occupancy, new buildings,
change of occupancy in existing building, or upgrading existing buildings to new electrical
load requirements.]
240-6. Standard Ampere Ratings.
(b) Adjustable Trip Circuit Breakers.
Exception:
