DON NELLY ENGINEERING ELECTRICAL <br /> 1.4 CONDUIT <br /> A. General: Provide a complete and continuous system of raceways to maintain a protected path for wires and <br /> cables to distribute electric power, and low voltage systems throughout the project, utilizing UL listed or <br /> NRTL (nationally recognized testing laboratory) and labeled materials. <br /> B. Accessories: Provide conduit accessories of types, sizes, and materials, as specified herein complying <br /> with manufacturers published product information, which match and mate conduit and tubing. <br /> C. Interior Minimum Size: Minimum conduit size for light and power systems shall be 3/4 inch conduit for all <br /> power and lighting circuitry homeruns from panelboard to outlet box at first power consuming devices. The <br /> remainder of circuitry may be in 1/2 inch conduit, if it contains no more than 4 conductors per conduit <br /> (excluding the equipment grounding conductor), and phase conductors no larger than #12 AWG. <br /> Switchlegs may be 1/2 inch conduit unless otherwise noted on drawings. <br /> D. Site Underground Conduit: Unless otherwise noted, minimum underground raceways shall be 1 inch <br /> conduit. Homeruns from the branch circuit overcurrent device, through any control devices to the first <br /> exterior junction box or device shall be 1 inch minimum. <br /> E. System Conduit: Provide end bushings on all conduits. <br /> F. Pull Strings: Provide pull strings in all empty raceways. Pull strings shall be nylon and shall be impervious <br /> to moisture. Pull strings installed in one inch and smaller conduits shall have a tensile strength of not less <br /> than 30 lbs. Pull strings installed in conduits larger than 1 inch shall a tensile strength not less than 200 lbs. <br /> G. Conduit Bends: The use of NEC.Table 346.10 Exception is not allowed. <br /> 1.5 LOCATIONS <br /> A. Materials Above Grade: The following conduit types are to be installed above grade where specifically <br /> noted herein; <br /> 1. Electrical metallic tubing (thin wall) <br /> 2. Intermediate metallic conduit Hospital Grade <br /> 3. Flexible metal conduit Hospital Grade only. Where specifically noted on drawings. . <br /> 4. Liquid-tight flexible metal conduit. Where specifically noted on drawings. <br /> 5. Galvanized rigid steel conduit <br /> B. Materials Below Grade: The following conduit types are to be installed below grade where specifically <br /> noted herein; <br /> 1. Rigid galvanized conduit(heavy wall) <br /> 2. Intermediate metal conduit(IMC) <br /> 3. Sched 40 PVC. Note: not allowed in or below patient care areas. <br /> PART2 -PRODUCTS <br /> 2.1 ELECTRICAL METALLIC TUBING <br /> i <br /> A. Fittings: Provide steel set screw fittings. Steel fittings-shall be fitted with nonremovable insulated throats, <br /> and male threaded ends provided with a locknut. <br /> B. Locknuts: Provide locknuts for securing conduit to enclosures with sharp edges for digging into metal, a'nd <br /> ridged outside circumference for proper fastening. <br /> i <br /> Heartland Health Care Center of Zephyrhills-3181 16110-2 DE No 217032 j <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
