CONDUIT, FITTINGS & SUPPORTS Section 16021 15-1207 backing and a corrosion resistant one (1) mil. metallic foil core to permit easy location of the duct line. d. Patch all coated conduit according to the manufacturer's recommendation. Completely coat all holidays and tool marks using paste recommended by manufacturer. Coat remaining exposed conduit threads with paste when installation is complete. 8. Cut conduit square, thread, and paint. Remove burrs and sharp edges at ends of each conduit with tapered reamer. Field Threads: Same type and have same effective lengths as factory threads. 9. Cap open ends of conduits with manufactured conduit seals as soon as installed and keep capped until ready to install conductors. Swab out conduits before wires are pulled in. 10. Terminate conduit with insulated bushings. Seal ends of conduit to prevent entrance of foreign material and protect threads. 11. Conceal conduit in all areas except within mechanical and electrical areas where they may be run exposed, if they cannot be concealed. a. Assemble conduit threads with anti -corrosion, conductive, anti -seize compound and tighten joints securely. Where conduit is embedded, paint wrench marks with "Glyptol" or equal. b. Install conduit so there will be no traps to collect condensation. C. Fasten conduit securely to boxes with locknuts and bushings to provide good grounding continuity. Terminate all conduit with insulating bushing or insulated throat. d. Rigid Steel Feeder Conduit Bushings shall be complete with non- removable insulated lining, O.Z. type "BLG" with lug type grounding connector, except where otherwise shown or specified. e. Make long radius conduit bends free from kinks, indentations or flattened surfaces. Make bends carefully to avoid injury or flattening. Bends in conduit one and one- quarter inch (1-1/4") size and larger shall be factory made ells, or be made with a manufactured mechanical bender. Heating of steel conduit to facilitate bending will not be permitted. Bend conduit cold to prevent damage to galvanized coating. Remove burrs and sharp edges at end of each conduit with tapered reamer. f. Where exposed, run conduit parallel with walls or structural elements; vertical runs plumb; horizontal runs level or parallel with structure as appropriate; groups racked together neatly with both straight runs, bends parallel, and uniformly spaced. Exposed conduit below eight feet (8') from floor shall be rigid type. Maintain a minimum of six inches (6") clearance from steam or hot water pipes. 12. Install exposed conduit as high as practical to maintain adequate headroom as shown or required. Notify Architect before installation whenever headroom of less than eight feet six inches (8'6") will result. Coordinate with Work of other Divisions to achieve proper headroom as specified in this Division. 13. Clearance: Do not obstruct spaces required by Code in front of electrical equipment, access doors, and similar items. 14. Penetrations: 5
