<br /> 135 <br /> RAMON LUCIO, RIO VISTA, RIO VISTA ANNEX, AND BICENTENNIAL <br /> PARKS RECREATION DEVELOPMENT <br /> TECHNICAL SPECIFICATION 9 <br /> ELECTRICAL WORK - GENERAL <br /> two 90 degree bends shall be made in any run. The inside radius of <br /> bends for 1/2 and 3/4 inch conduit shall be at least 6 times the <br /> trade size, and for 1 inch conduit and larger at least 10 times the <br /> trade size. <br /> (b) Conductors: Conductors smaller than No. 2 AWG <br /> installed in ordinarily dry locations shall be Type THW. Conductors <br /> smaller than No.2 AWG installed in wet locations such as in <br /> underground raceways installed in concrete or masonry floor slabs <br /> in direct contact with earth, or in raceways regularly subject to <br /> moisture or condensation shall be rubber-insulated and <br /> lead-covered, Type RL, Type USE (Style RR) or <br /> thermoplastic-insulated specifically designed for such <br /> applications, Type RHW. Conductors No. 2 AWG and larger shall be <br /> heat resistant grade, rubber insulated, Type RH, for use in dry <br /> locations, and lead-covered, Type RHL, or Type USE (Style RR) for <br /> use in wet locations. Rubber-insulated conductors, Type R, RL, RH, <br /> and RHL, shall conform to the requirements of Federal Specification <br /> J-C-103. Type USE (Style RR) conductors shall conform to the <br /> Underwriters' Laboratories, Inc., Standard for Service Cables. <br /> Thermoplastic-insulated conductors, Types T and TW, shall conform <br /> to the requirements of the Underwriters' Laboratories, Inc. , <br /> Standard for Thermoplastic-Insulated Wires. Home runs may be <br /> combined in one conduit, provided all connections are in accordance <br /> with National Electrical Code requirements and the maximum <br /> unbalanced current in the neutral does not exceed the capacity of <br /> the conductor. <br /> 9-06 OUTLETS: <br /> a. OUtlets shall be installed in the locations shown on the <br /> drawings. The Contractor shall study the general building plans in <br /> relation to the spaces surrounding each outlet in order that his <br /> work may fit the other work required by these specifications. When <br /> necessary, the Contractor shall relocate outlets so that, when <br /> fixtures or other fittings are installed, they will be <br /> symmetrically located according to room layout and will not <br /> interfere with other work or equipment. In general, outlets shall <br /> be installed at the mounting heights shown on the drawings. In <br /> masonry walls, the outlets shall be located with the bottom of the <br /> outlet occurring at the first horizontal mortar joint below the <br /> specified mounting height, but in no case shall any outlet be <br /> mounted less than 8 inches above the floor. The space around outlet <br /> boxes in 4-inch thick masonry partitions shall be filled with <br /> mortar or concrete. Zinc-coated or cadmium plated sheet-steel boxes <br /> 9-5 <br />
