RESOLUTION NO. 91-116
A RESOLUTION OF THE CITY COUNCIL OF
THE CITY OF SANTA ANA MAKING CERTAIN
FINDING WITH REGARD TO AMENDMENTS TO
THE 1990 EDITION OF THE NATIONAL
ELECTRICAL CODE.
WHEREAS, the City Council proposes to approve an ordinance
adopting the 1990 edition of the National Electrical Code published
by the National Fire Protection Association; and
WHEREAS, the City Council considers it necessary, because of
local climactic, geological or topographical conditions, to amend
certain building standards in the National Electrical Code, 1990
edition, as hereafter set forth; and
WHEREAS, pursuant to sections 17958.5, 17958.7 and 18941.5 of
the Health and Safety Code of the State of California, the City
Council is required to make findings that such amendments are
necessary due to local climactic, geological, or topographical
conditions, and to file such findings, together with the amend-
ments, with the Department of Housing and Community Development of
the State of California;
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY
OF SANTA ANA AS FOLLOWS:
1. Section 8-815 of the Santa Ana Municipal Code amends, and
will continue to amend, section 210-1 of the National Electrical
Code as follows:
"Bee. 8-815. conductors (Section 110-5).
Section 110-5 of the National Electrical Code is amended by
adding a second sentence to read as follows:
Ail sections of this National Electrical Code allowing
the use of aluminum conductors are subject to the
limitation that no aluminum conductor smaller than No. 6
AWG shall be used."
The City Council hereby finds and determines that earthquakes
are a common occurrence in the local area; that earthquakes may
cause electrical connections and screws to loosen, causing heat
problems especially in the smaller sizes of aluminum wire; and that
the above amendment is necessary to address the risk of fire due to
such causes.

2. Proposed sections 8-941 and 8-942 of the Santa Ana
Municipal Code will amend section 336-3 and 336-4 of the National
Electrical Code to read as follows:
"336-3. Uses Permitted. Type NM and Type NMC cables shall be
permitted to be used in one- and two-family dwellings,
multifamily dwellings and other structures, except as
prohibited in Section 336-4. Where installed in cable trays,
cables shall be identified for this use.
(FPN) See Section 310-10 for temperature limitation of conductors.
(a) Type NM. Type NM cable shall be permitted for concealed
work in normally dry locations. It shall be permissible to
install or fish Type NM cable in air voids in masonry block or
tile walls where such walls are not exposed or subject to
excessive moisture or dampness.
(b) Type NMe. Type NMC cable shall be permitted: (1) for
concealed work in dry, moist, damp, or corrosive locations;
(2) in outside and inside walls of masonry block or tile, (3)
in a shallow chase in masonry, concrete, or adobe protected
against nails or screws by a steel plate at least 1/16 inch
(1.59 mm) thick and covered with plaster, adobe, or similar
finish.
336-4. Uses Not Permitted.
(a) Type NM or NMC. Types NM and NMC cables shall not be
used: (1) in any dwelling or structure exceeding three floors
above grade; (2) as service-entrance cable; (3) in any
nonresidential building or structure; (4) in hoistways; or (5)
embedded in poured cement, concrete, or aggregate. For the
purpose of this article, the first floor of a building shall
be that floor that has fifty percent or more of the exterior
wall surface area level with or above finished grade. One
additional level that is the first level and not designed for
human habitation and used only for vehicle parking, storage,
or similar use shall be permitted.
(b) Type NM. Type NM cable shall not be installed: (1) where
exposed to corrosive fumes or vapors; (2) where embedded in
masonry, concrete, adobe, fill, or plaster; (3) in a shallow
chase in masonry, concrete, or adobe and covered with plaster,
adobe, or similar finish."
The city Council hereby finds and determines that earthquakes
are a common occurrence in the local area; that, unlike wire
installed in conduit or raceways, non-metallic sheathed cable does
not provide the degree of protection that is needed in the event of
an earthquake; that exposed non-metallic sheathed cable is

particularly hazardous; and that this amendment is necessary to
assure that adequate protection is provided in the workplace and in
other places of public gathering.
3. The Clerk of the Council is directed to file a certified
true copy of this resolution with the Department of Housing and
Community Development of the State of California.
