Conduit, Fittings and Supports: <br />1. Rigid Steel Conduits (RSC), Condulets, and Fittings: Hot -dipped galvanized; ANSI C80.1, <br />UL6, and FS WW -C-581 E. <br />2. Intermediate Metallic Conduit (IMC): Hot -dipped galvanized; UL 1242 and FS WW -C-581 E. <br />3. Electrical Metallic Tubing (EMT): Electro -galvanized; ANSI C80.3, UL 797, and FS WW -C- <br />563. EMT only on interior of buildings. <br />4. Coated Rigid Steel Conduit: Polyvinyl -chloride (PVC) coating factory bonded to outer <br />surface of RSC conduit. Bond between PVC coating and conduit surface shall be greater <br />than the tensile strength of PVC. Thickness of Coating: Forty (40) mil. minimum. Tensile <br />Strength: 3500 psi. All fittings with same coating as conduit, PVC sleeve over fittings shall <br />extend beyond the hub or coupling approximately one (1) diameter or one and one-half <br />inches (1 1/2"), whichever is smaller. Coated Conduit: NEMA Standard RNI (Type A). <br />Occidental Coating Company 'COCCAL -40", Plastic Applicators t'KorKap", RobRoy industries <br />tt Pl1 A Jf1 I <br />asti-Bona or equal. <br />5. PVC Conduit: Type 40 and Type 80, ninety degrees (90°) C., composed of polyvinyl- <br />chloride, NEMA TC -2, TC -3 (fittings UL 514), FS W -C -1094A, UL 651 and ANSI C33.91. <br />Tensile Strength: 7,000 psi at seventy-three point four degrees (73.40) F. Flexural Strength: <br />11,000 psi. Compressive Strength: 8,600 psi. Fittings shall be by same manufacturer. <br />Joints: Solvent welded. <br />6. Flexible Conduit: FS WW -C-566. Flexible steel, zinc coated on both inside and outside by <br />hot -dipping process, interlockedspirallywound steel strip. Liquid tight flexible conduit shall <br />be with extruded polyvinyl covering and with continuous copper bonding conductor wound <br />spirally between convolutions or installed with ground type end fittings at each end to <br />accommodate grounding jumper to provide continuous ground bond. Minimum size: One- <br />half inch (1/2") except where supplied as part of an approved manufactured assembly <br />integrally wired into recessed light fixtures. <br />7. Fittings: UL Standard No. UL 514 and listed in UL Electrical Construction Materials List. <br />8. Fittings types: <br />a. Condulets: Crouse -Hinds "Form 8" or equal. <br />b. Flexible Conduit Fittings: Squeeze type, clamp type or water -tight type with gland <br />nut where required with insulated throats. Set screw type, not acceptable. <br />L <br />
