SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br />BASIC ELECTRICAL MATERIALS AND METHODS 16050-5 <br />A. Headroom Maintenance: If mounting heights or other location criteria are not indicated, arrange and install <br /> components and equipment to provide the maximum possible headroom. <br /> <br />B. Materials and Components: Install level, plumb, and parallel and perpendicular to other building systems <br /> and components, unless otherwise indicated. <br /> <br />C. Equipment: Install to facilitate service, maintenance, and repair or replacement of components. Connect <br /> for ease of disconnecting, with minimum interference with other installations. <br /> <br />D. Right of Way: Give to raceways and piping systems installed at a required slope. <br /> <br />3.2 <br /> <br />ELECTRICAL SUPPORTING DEVICE APPLICATION <br />A. Damp Locations and Outdoors: Hot-dip galvanized materials or nonmetallic, U-channel system <br /> comp onents. <br /> <br />B. Dry Locations: Steel materials with corrosion-resistant coating. <br /> <br />C. Support Clamps for PVC Raceways: Click-type clamp system. <br /> <br />D. Selection of Supports: Comply with manufacturer's written instructions. <br /> <br />E. Strength of Supports: Adequate to carry present and future loads, times a safety factor of at least four; <br /> minimum of 200-lb design load. <br /> <br />3.3 <br /> <br />SUPPORT INSTALLATION <br />A. Install support devices to securely and permanently fasten and support electrical components. <br /> <br />B. Install individual and multiple raceway hangers and riser clamps to support raceways. Provide U-bolts, <br /> clamps, attachments, and other hardware necessary for hanger assemblies and for securing hanger rods and <br /> conduits. <br /> <br />C. Support parallel runs of horizontal raceways together on trapeze- or bracket-type hangers. <br /> <br />D. Size supports for multiple raceway installations so capacity can be increased by a 25 percent minimum in <br /> the future. <br /> <br />E. Support individual horizontal raceways with separate, malleable-iron pipe hangers or clamps. <br /> Install 1/4-inch- diameter or larger threaded steel hanger rods, unless otherwise indicated. <br /> <br />G. Spring-steel fasteners specifically designed for supporting single conduits or tubing may be used instead of <br /> malleable-iron hangers for 1-1/2-inch and smaller raceways serving lighting and receptacle branch circuits <br /> above suspended ceilings and for fastening raceways to slotted channel and angle supports. <br /> <br />H. Arrange supports in vertical runs so the weight of raceways and enclosed conductors is carried entirely by <br /> raceway supports, with no weight load on raceway terminals. <br /> <br />I. Simultaneously install vertical conductor supports with conductors. <br /> <br />J. Separately support cast boxes that are threaded to raceways and used for fixture support. Support sheet- <br /> metal boxes directly from the building structure or by bar hangers. If bar hangers are used, attach bar to <br /> raceways on opposite sides of the box and support the raceway with an approved fastener not more than 24 <br /> inches from the box. <br />
