SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />RACEWAYS AND BOXES 16130 - 4 <br />A. Examine surfaces to receive raceways, boxes, enclosures, and cabinets for compliance with instal- <br />lation tolerances and other conditions affecting performance of raceway installation. Do not pro- <br />ceed with installation until unsatisfactory conditions have been corrected. <br />3.2 <br /> <br />WIRING METHODS <br />A. Outdoors: Use the following wiring methods: <br />1. Exposed: Rigid steel. <br />2. Concealed: Rigid steel or RNC. <br />3. Underground, Single Run: RNC. <br />4. Underground, Grouped: RNC. <br />5. Connection to Vibrating Equipment (Including Transformers and Hydraulic, Pneumatic, <br /> Electric Solenoid, or Motor-Driven Equipment): LFMC. <br />6. Boxes and Enclosures: NEMA 250, Type 3R or Type 4. <br />B. Indoors: Use the following wiring methods: <br />1. Exposed: EMT. <br />2. Concealed: EMT, RNC, or “MC” cable. <br />3. Connection to Vibrating Equipment (Including Transformers and Hydraulic, Pneumatic, <br /> Electric Solenoid, or Motor-Driven Equipment): FMC; except in wet or damp locations, <br /> use LFMC. <br />4. Damp or Wet Locations: Rigid steel conduit or RNC. <br />5. Boxes and Enclosures: NEMA 250, Type 1, except as follows: <br /> a. Damp or Wet Locations: NEMA 250, Type 3R. <br /> <br />3.3 <br />A. Install raceways, boxes, enclosures, and cabinets as indicated, according to manufacturer's written <br /> instructions. <br /> <br />B. Minimum Raceway Size: 1/2-inch trade size (DN16). <br />C. Minimum Homerun Size: 3/4-inch trade size (DN21). <br />D. EMT shall be concealed within new finished walls, and above suspended ceilings. <br />E. RNC shall be concealed below slabs and grade. <br />F. Install raceways level and square and at proper elevations. Provide adequate headroom. <br />G. Complete raceway installation before starting conductor installation. <br />H. Support raceways as specified in Division 16 Section "Basic Electrical Materials and Methods." <br />I. Use temporary closures to prevent foreign matter from entering raceways. <br />J. Protect stub-ups from damage where conduits rise through floor slabs. Arrange so curved portion <br /> of bends is not visible above the finished slab. <br />K. Make bends and offsets so ID is not reduced. Keep legs of bends in the same plane and straight <br /> legs of offsets parallel, unless otherwise indicated. <br />L. Use raceway fittings compatible with raceways and suitable for use and location. For rigid steel <br /> conduit, use threaded rigid steel conduit fittings, for EMT use all steel set screw or compression <br /> fittings.
