RESOLUTION 95-081 315 Ail sections of this National Electrical Code allow- ing 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. 4. Section 8-942 of the Santa Ana Municipal Code amends, and will continue to amend, section 336-4 of the National Electrical Code to read as follows: 336-4. Uses Not Permitted. (a) Type NM or NMe. Types NM and NMC cables shall not be used: (1) in any dwelling or structure ex- ceeding three floors above grade; (2) as service- entrance cable; (3) in any nonresidential building or structure; (4) in hoist-ways; or (5) embedded in poured cement, concrete, or aggregate. For the purpose of this article, the first floor of a build- ing 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 habita- tion 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, con- crete, or adobe and covered with plaster, adobe, or similar finish. The City Council 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 particular- ly hazardous; and that this amendment is necessary to assure that adequate protection is provided in the workplace and in other places of public gathering. 5. 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. 3
