accordance with the conditions of the listing and the manufacturer's installation instructions.
Kerosene and oil -fired stoves shall comply with *Tz. R A 31 this code, the Fire Code and the
Building Code. Oil -fired stoves shall be tested in accordance with UL 896.
REASON: To require compliance with applicable provisions in the building, mechanical, and
fire code instead of NFPA documents, which may be difficult to access and enforce.
"Section 1204.1 and 1204.2; changed to read as follows:
1204.1 Insulation characteristics. Pipe insulation installed in buildings shall conform to the
requirements of the energy code, when adopted. shall be tested in accordance with ASTM E 84

necessary apparatus for conducting tests shall be furnished by the permit holder.
REASON: To provide a specific testing method.
"Section 1401.1 add a second paragraph to read as follows:

REASON: To provide clarity on which codes govern when conflicts arise.
**Section 1401.2 is changed to read as follows:
1401.2 Storage systems. Fuel oil storage and piping systems shall be installed in accordance

**Sections 1401.2.1, 1401.2.2 and 1401.2.3 are deleted
REASON: For compatibility with other code changes.
**Any section or table not reprinted herein shall be assumed to be deleted Chapter 15 is
changed to only read as follows:
CHAPTER 15
SECTION 1501- GENERAL
1501.1 Scope. This chapter shall govern the construction, installation, alteration and repair of
systems and equipment intended to utilize solar energy for space heating or cooling, domestic hot
water heating, swimming pool heating or process heating.
1501.2 Potable water supply. Potable water systems shall be protected against contamination in
accordance with the plumbing code.
1501.3 Heat exchangers. Heat exchangers used in domestic water -heating systems shall be
approved for the intended use. The system shall have adequate protection to ensure that the
potability of the water supply and distribution system is properly safeguarded.
1501.5 Ducts.. Ducts utilized in solar heating and cooling systems shall be constructed and
installed in accordance with Chapter 6 of this code.
REASON: To make these provisions easier to enforce since most cities in this region do not
adopt the energy code.

Regional Amendments and Interpretations*
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.
i ir' i. i �_• i' _•i a _! i t it
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 any one location.
Exception No. 1: Afulti-oc==t Buildings. Individual service disconnecting means limit
to six for each occupant. The number of individual disconnects atone 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 part of the listed equipment, shall
not be considered a service disconnecting means.
D_1 i 24
REASON FOR CHANGE: The same reasoning as for multi -family dwellings in Section 230-2
except now it is being applied to multioccupant buildings.
*NOTE: i nderlininy indicates new words and phrases to be added to the 1996 National
Electrical Code. Strilfeeats indicate existing words and phrases to be deleted.
250-81. Grounding Electrode System. If available on the premises at each building or structure
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 quaked persons will service the installation and the entire length
of the interior metal water pipe that is being used for the conductor is exposed.
(ITN): 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 permitted 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 through 10-19 shall not
be used in conjunction with Section 20- 0
D-2 125
REASON FOR CHANGE: To provide a more reasonable margin of safety for dwelling service
and feeder conductor allowable ampacities.
3365. 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 family dwelling.
Exception No. 2: An additional level shall be permitted in dwellings where the entire structure
is protected throughout by an approved automatic =dnkGler system
(2) As service -entrance cable.
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
210-52. Dwelling Unit Receptacle Outlets.
(d) Bathrooms.
[A single duplex receptacle located a reasonable distance between two basins will meet the
requirements of this section.]

[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.]
