r <br /> r <br /> SECTION 630 <br /> CONDUIT <br /> ar <br /> 630-1 Description. <br /> Install conduit for traffic signals and other electrically powered or operated traffic control <br /> r devices as shown in the plans and Design Standards, Index No. 17721 . <br /> 630-2 Materials. <br /> r Use materials meeting the requirements of Section A630 of the current Minimum <br /> Specifications for Traffic Control Signal Devices (MSTCSD), except as provided in 603-2.2 . <br /> No 630-3 Installation Requirements. <br /> 630-3. 1 General: Consider the locations of conduit as shown on the plans as <br /> approximate. Construct conduit runs as straight as possible, and obtain the Engineer' s approval <br /> w of all major deviations in conduit locations from those shown on the plans. <br /> Do not place more than the equivalent of four quarter bends or 360 degree of <br /> bends, including the termination bends, between the two points of termination in the conduit, <br /> r without a pullbox. Obtain the Engineer' s approval to use corrugated flexible conduits for short <br /> runs 6 feet or less. <br /> Use only intermediate metal conduit, rigid galvanized conduit, rigid aluminum <br /> it conduit or PVC coated intermediate metal conduit for above-ground or underground electrical <br /> power service installations. Meet the requirements of Section 562 for coating all field cut and <br /> threaded galvanized pipe. <br /> r Use either schedule 80 PVC or fiberglass reinforced epoxy conduit for <br /> installations on bridge decks. <br /> Use either schedule 40 PVC or fiberglass reinforced epoxy, conduit for <br /> r underground and under pavement installations, except for electrical power service. <br /> When the installation of a conduit requires jacking under paved surfaces, <br /> railroads, etc., use an intermediate metal conduit as the sleeve for the underground conduit. <br /> r Install the underground conduit as shown in the Design Standards, Index No. 17721 . <br /> When a conduit installation changes from underground to above-ground, make <br /> the change a minimum of 6 inches below finished grade. <br /> r Install a No. 12 AWG pull wire or polypropylene cord the full length of all <br /> conduits that are designated for future use. Ensure that a minimum of 24 inches of pull line <br /> approved by the Engineer is accessible at each conduit termination. <br /> _ w Install an expansion fitting when conduit crosses an expansion joint of a structure . <br /> Use couplings and expansion joints made of the same material as the conduit. <br /> Ensure that all joints are made as specified by the manufacturer and are <br /> waterproof. <br /> For installations not specifically shown, install the conduit in accordance with <br /> NEC and/or National Electrical Safety Code requirements. <br /> When earth backfill and tamping is required, place backfill material as per <br /> Section 120 in layers approximately 12 inches thick, and tamp each layer to a density equal to or <br /> greater than the adjacent soil. <br /> + ' When trenching, saw cut and repair all pavement and sidewalks encountered. <br /> r <br /> r <br />
