SAMSON OCEANFRONT PARK CITY OF SUNNY ISLES TECHNICAL SPECIFICATIONS RACEWAYS AND BOXES 16130 - 5 M. Run concealed raceways, with a minimum of bends, in the shortest practical distance considering the type of building construction and obstructions, unless otherwise indicated. N. Install exposed raceways parallel to or at right angles to nearby surfaces or structural members, and follow the surface contours as much as practical. 1. Run parallel or banked raceways together, on common supports where practical. 2. Make bends in parallel or banked runs from same centerline to make bends parallel. Use factory elbows only where elbows can be installed parallel; otherwise, provide field bends for parallel raceways. O. Join raceways with fittings designed and approved for the purpose and make joints tight. 1. Make raceway terminations tight. Use bonding bushings or wedges at connections subject to vibration. Use bonding jumpers where joints cannot be made tight. 2. Use insulating bushings to protect conductors. P. Tighten set screws of threadless fittings with suitable tools. Q. Terminations: Where raceways are terminated with locknuts and bushings, align raceways to enter squarely and install locknuts with dished part against the box. Where terminations are not secure with 1 locknut, use 2 locknuts: 1 inside and 1 outside the box. R. Where raceways are terminated with threaded hubs, screw raceways or fittings tightly into the hub so the end bears against the wire protection shoulder. Where chase nipples are used, align race ways so the coupling is square to the box and tighten the chase nipple so no threads are exposed. S. Install pull wires in empty raceways. Use No. 14 AWG zinc-coated steel or monofilament plastic line with not less than 200-lb (90-kg) tensile strength. Leave at least 12 inches (300 mm) of slack at each end of the pull wire. T. Telephone and Signal System Raceways, 2-Inch Trade Size (DN53) and Smaller: In addition to the above requirements, install raceways in maximum lengths of 150 feet (45 m) and with a max imum of two 90-degree bends or equivalent. Separate lengths with pull or junction boxes where necessary to comply with these requirements. U. Install raceway sealing fittings according to manufacturer's written instructions. Locate fittings at suit- able, approved, and accessible locations and fill them with UL-listed sealing compound. For concealed raceways, install each fitting in a flush steel box with a blank cover plate having a finish similar to that of adjacent plates or surfaces. Install raceway sealing fittings at the following points: 1. Where conduits pass from warm to cold locations, such as the boundaries of refrigerated spaces. 2. Where otherwise required by NFPA 70. V. Stub-up Connections: Extend conduits through concrete floor for connection to freestanding equipment. Install with an adjustable top or coupling threaded inside for plugs set flush with the finished floor. Extend conductors to equipment with rigid steel conduit; FMC may be used 6 inches (150 mm) above the floor. Install screwdriver-operated, threaded flush plugs flush with floor for future equipment connections. W. Flexible Connections: Use maximum of 6 feet (1830 mm) of flexible conduit for recessed and semirecessed lighting fixtures; for equipment subject to vibration, noise transmission, or move ment; and for all motors. Use liquidtight flexible conduit in wet or damp locations. Install sepa rate ground conductor across flexible connections. X. Surface Raceways: Install a separate, green, ground conductor in raceways from junction box supply- ing the raceways to receptacle or fixture ground terminals.
