ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />CONDUIT 260111 - 6 <br />O. Tag empty conduits at each accessible end with a permanent tag identifying the purpose of the <br />conduit and the location of the other end. In wet, corrosive outdoor or underground locations, <br />use brass, bronze, or copper 16 gage tags or lead tags secured to conduit ends with #16 or larger <br />galvanized wire. Inscribe on the tags with steel punch dies clear and complete identifying <br />information. <br />P. Bends: <br />1. Raceways for Sound System, Telephone System, LAN, and Video System cables shall be <br />designed for the installation of Fiber Optic cable. <br />2. All bends or elbows shall have a minimum radius as follows: <br /> <br /> Conduit Size (inches) Min. Radius (inches) <br /> 3/4 12 <br /> 1 12 <br /> 1-1/4 18 <br /> 1-1/2 <br /> 2 24 <br /> 2-1/2 24 <br /> Conduit Size (inches) Min. Radius (inches) <br /> 3 36 <br /> 3-1/2 36 <br /> 4 48 <br /> 5 48 <br /> 6 48 <br /> <br />3.2 Use factory ells at conduit bends 1-1/4" and larger. Alternative method: Use of precision <br />conduit bending machine equivalent to Greenlee 'One Shot' or 'Smart Bender'. <br />A. Boxes where the cable changes direction shall be large enough to allow cables in the box to <br />have a 12" minimum radius. <br />B. Make bends and offsets so the inside diameter is not effectively reduced. Make bends in <br />parallel or banked runs from the same center line so that the bends are parallel. <br />3.3 CONDUIT INSTALLATION <br />A. Cut conduit square using a saw or pipe cutter; de-burr cut ends. <br />B. Bring conduit to the shoulder of fittings and couplings and fasten securely. <br />C. Use conduit hubs or sealing locknuts for fastening conduit to cast boxes, and for fastening <br />conduit to sheet metal boxes in damp or wet locations. <br />D. Install no more than the equivalent of three 90-degree bends between boxes. Keep bends and <br />offsets in conduit runs to an absolute minimum. For the serving utilities, make large radius <br />bends to meet their requirements. Replace deformed, flattened or kinked conduit.
