Resolution No. 1723n ,^r.l ,G r0 RESOLUTION NO. 1723 A RESOLUTION OF THF CITY COUNCIL OF THE CITY OF CYPRESS SETTING FORTH THE LOCAL CONDITIONS AND THE PUBLIC SAFETY FACTORS UPON WHICH A DETERMINATION HAS BEEN MADE BY THE CITY COUNCIL THAT CERTAIN MODIFICATIONS TO THE 1975 EDITION OF THE NATIONAL ELECTRICAL CODE ARE REASONABLY REQUIRED BY LOCAL CONDITIONS AND PUBLIC SAFETY FACTORS WITHIN THE CITY OF CYPRESS. THE CITY COUNCIL OF THE CITY OF CYPRESS DOES HEREBY RESOLVE AS FOLLOWS: WHEREAS, Health and Safety Code Section 17958 requires the City of Cypress to adopt the 1975 edition of the National Electrical Code; and WHEREAS, Health and Safety Code Section 17958.5 provides for the City Council to make changes or mnv'ifications in the 1975 edition of the National Electrical Code as may be reasonably necessary because of local conditions, and WHEREAS, the City Council also has authority to modify said code based upon public safety considerations; and WHEREAS, the Building Official of the City of Cypress has determined and recommended that based upon factors of public safety and local conditions within the City of Cypress, the modifications to the 1975 edition of the National Electrical Code contained in Ordinance No. are reasonably required to be adopted by the City of Cypress, and WHEREAS, Health and Safety Code Section 17958.7 requires the City Council to make express findings of the necessity for modifications in the 1975 edition of the National Electrical Code; NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Cypress that the amendments and modifications to the 1975 edition of the National Electrical Code contained in Ordinance No. are hereby found to be reasonably necessary due to considerations of public safety and the local conditions as follows: Section 210-1 Branch Circuits (a) It is necessary to require these services to be placed underground due to the incidence of accidental contact by metal ladders, pipe, kites, swimming pool scoops and brushes, cranes and other similar items. These overhead conductors are also subject to being disconnected as a result of wind storms. (b) If raceways are not provided when spare circuits are provided for, a hazard is created when additional wiring is added. Section 210-25-E Receptacle Outlets Required. This requirement provides the minimum in reliability and safety in electrical systems for small and major appliances. This allows for replacing of an appliance with a larger one, in 1"0-9 1 most cases, without additional wiring. A fault in an appliance will not interrupt any other circuit, possibly cutting off power to receptacles throughout occupancy. In Cypress, garages are used almost exclusively as storage areas. In addition, work benches, electric tools, saws, drills, etc., are often located in the garage since it is accessible for workshelves. It is necessary that wiring be provided in this garage, since if it is not the likelihood of inadequate wiring provided by untrained personnel is present. Section 215-10 Raceways. Since the greatest fault current will occur either in the service conduit, service section, feeder conduit and subpanels, these major parts should be inclosed to prevent fire being immediately transferred to the structure. Section 230-43 Services. Any other form of service conductor raceway would be subject to mechanical damage and would not afford the protection needed for fault currents available. In addition, Cypress is subject to salt air environment creating rapid corrosion of other forms of raceway. Section 230-71 Maximum Number of Disconnects. Allows six main switches instead of the present one per occupancy. All six would be required to be burned off to completely disconnect power from a building or occupancy. It has been found that otherwise the occupants tie on to the buss bars for extra loads, the panel buss is overloaded and since there is no main switch the buss burns up. Section 250-83 Made Electrodes. Alternate electrodes to those basically provided for in the National Electric Code do not provide adequate grounding means in the soil conditions experienced in Cypress. The ufer ground or the concrete cased electrode has gained wide acceptance by the industry and it felt that this is a more preferable way to provide grounding, especially with the advent of plastic water services. Section 300-13(b) Wiring Methods. When two (2) or more are on the same circuit they could carry more than they are rated for causing a hazard. Section 300-15. Boxless Devices. Requires special tools for installation and to repair or replace. Section 334 Metal -Clad Cable. Has been deleted as the metal clad cable is too susceptible to injury in handling. Section 336-3 Non -Metallic Sheath Cable Some of the more important concerns with this wiring method are: 1. Penetration of the cable unknowingly by nails, screws, etc., inside walls by persons in- stalling pictures, cabinets, etc., after structure is finished. 2. Mechanical damage to cables by workmen during construction. 3. Safety hazards created by persons attempting to add new wiring. (Open splices in attics, etc.) This is a common practice for "Do it yourselfers", tenants, or owners. 4. The raceway protects the structure from immediately being ignited by a fault in the system as is the case with cables. 5. Keeps the electrical system operating longer for elevators, exit lights, ec., during a fire or similar type of emergency. 6. Allows a person to replace an existing small appliance with a larger one (water heater, etc.) without over -fusing an existing cable or replacing it completely. 7. Allows changes and modifications in electrical system during construction and later to tenants specific needs, at a large cost savings. 8. Cuts down amount of hazardous cord wiring, prevalent in structures wired with cables, since new circuits can be added safely and to code in existing conduits. This is provided for in the rewire tables of National Electrical Code. Section 348-1 Electrical Metallic Tubing. The prohibition of the use of this material in concrete or underground is due to the following items: 1. Corrosive soil prevalent in Cypress area. 2. Vibration by mechanical devices used during the pouring of concrete. 3. Sodium chloride additives and their corrosive effect. 4. Mechanical damage by workmen and equipment during the construction process. Section 350-2. Flexible Metal Conduit. Flexible metal conduit is coming in to use more and more as an exposed method of wiring, especially in garages of single family dwellings. If it is to be exposed care must be taken to prevent physical damage, since it has no mechanical strength to support its own weight. 276 Section 442-5 This amendment will provide for adequate wiring for fixed appliances which draw larger loads than most other loads found in residential usage. In addition, most cases involve motors and motors of course draw higher current while starting and separate circuits should be used for their use so that lamps and other devices are not denied power if they are located on the same circuit. A food waste grinder should be provided with a separate circuit of its own due to the likelihood of stalling by metal objects falling into the disposal and this would not effect the other applicances if it were on a separate circuit. BE IT FURTHER RESOLVED that a copy of this Resolution, together with the Ordinance adopting the National Electrical Code as amended, be filed with the State Department of Housing and Community Development by the City Clerk of the City of Cypress. PASSED AND ADOPTED by the City Council of the City of Cypress at a regular meeting held on the 24th day of May 1976.
