Section 4. That a new section to the Electrical Code be added thereto and numbered 2-319, and it shall read as follows: 2-319 NATIONAL ELECTRICAL CODE: The National Electrical Code of 1978 is hereby adopted with the below-stated additions, which additions, if in conflict with the National Electrical Code, shall overrule said Code: (a) BARE GROUNDED CONDUCTORS: NEC 230-30 Exception and NEC 230-4 Bare copper for direct burial where bare copper is judged to be suitable for the soil conditions. Because of varied soil conditions in the area, all grounded (neutral) conductors must be insulated as required by NEC 310-6. No bare grounded (neutral) conductors will be approved for direct burial. (b) MAXIMUM RATING OF EQUIPMENT: The maximum rating of circuit breakers, switches and other equipment shall be determined by the manufacturer's label or other markings. See Section 110-21 of the National Elecgrical Code. 120 ORDINANCE NO. 336 In no case will electrical equipment be approved when it is found that the manufacturers label has been altered or when the minimum requirements exceed the manufacturers rati__ng as determi ned by the 1 abel or other marki ngs. (c) BUILDINGS MOVED FROM ONE LOCATION TO ANOTHER: When a building is moved from one location to another the service entrance shall be inspected and made to conform to the requirements of the current edition of the National Electrical Code. (d) UNFINISHED STUDDED PARTITIONS: On November 2, 1963, the State Electri- cal Board ruled that when unfinished studded partitions are in place in resident- ial basements, indicating that the enclosed areas are intended for rooms, such enclosed areas shall be considered as rooms. The wiring, including receptacle outlets as required by Section 210-25(b) of the National Electrical Code shall be installed before the wiring of the building is approved. (e) SUPPORTING PARTITIONS: When a residential basement is not divided into separate rooms and only an unfinished supporting partition is in place, at least two outlets shall be installed in such supporting partition, facing the area on opposite sides of the partition. (f) UTILITY AND STORAGE SPACES: The requirement that receptacle outlets be installed within six feet from any wall space in dwelling type occupancies (Section 210-25(b) National Electrical Code) does not apply to hallways, bath- rooms, utility rooms, laundry rooms, furnace rooms and storage spaces. The number of outlets in these areas is optional, but adequate branch circuit capacity must be provided for lighting and for all electrical equipment to be installed in such areas without the use of extension cords. (g) LOCATION OF SERVICE EQUIP~1ENT: Service equipment shall not be installed in clothes closets, cupboards, toilets, bathrooms or attics. (h) SEPARATION OF BUILDINGS BY FIRE WALLS: cal Code permits only one service to a building. In general the National Electri- (Sections 230-21 and 230-2.) Article 100 of the National Electrical Code defines a building as "A structure which stands alone or which is cut off from adjoining structures by fire walls with all openings therein protected by approved fire doors." For the purpose of determining the number of services which may be run to a building or structure a fire wall shall be a masonary wall, not less than 4 inches thick, which extends from the foundation to the roof sheathing. (Bulletin #52 issued June 1, 1966.) (i) WEATHERPROOF SWITCH ENCLOSURES REQUIRED: On and after July 1, 1960, switches, circuit-breakers, panels and motor controllers installed where EXPOSED TO THE WEATHER shall be in weatherproof enclosures as required by Sections 373-2 and 380-4 of the National Electrical Code. (j) ALUMINUt~ CONDUIT FOR MAST TYPE SERVICES PROHIBITED: Where the service conduit is used as a mast to ~upport the service drop, RIGID STEEL CONDUIT SHALL BE USED. Aluminum conduit will not be approved for this purpose unless approved BRACES are provided to relieve the conduit of horizontal strain. Guy wires will not be approved for this purpose. (k) INSTALLATIONS AT OVER 600 VOLTS: Due to the many misunderstandings and misinterpretations of the National Electrical Code requirements for conductors and service disconnects, etc., on installations of over 600 volts, it has become necessary to require that all installations of voltages over 600 volts that are customer owned or operated must be submitted for prior plan approval to the Electrical Board representative in the area in which the installation is to be made. (1) REQUIREMENTS FOR TERMINAL CONNECTIONS OF RECEPTACLES AND SWITCHES ON 15 AND 20 AMPERE CIRCUITS: The following method is required in an attempt to reduce the heating and burning of screw terminals on switches and receptacles when aluminum branch circuit wiring connects to such devices: 1. Copper conductors 4 to 6 inches long of the same ampacity as the circuit to which they are attached must be connected to the wiring terminals and grounding terminals of the devices. ." ..
