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. RESOLUTION 91-116 Page 2 08~ 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 RESOLUTION 91-116 Page 3 082 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.
