DONNELLY ENGINEERING ELECTRICAL <br /> Q. Identification: Provide appropriate identification as required by codes and as indicated on the drawings <br /> and in accordance with the methods specified herein. <br /> R. Conduit: Conduits shall be anchored down to prevent floating while pouring in concrete. <br /> 3.4 RIGID METALLIC CONDUIT <br /> A. Locknuts: Rigid steel box connections shall be made with double locknuts and bushings. Turn down on <br /> threads to solidly connect raceway to box or enclosure. <br /> B. Bushings: Grounded insulated bushings shall be used on all rigid steel conduits terminating in panels, wire <br /> gutters, or cabinets in accordance with NEC 517 applicable sections. Bushing shall be impact resistant <br /> plastic molded in an irregular shape at the top to provide smooth insulating surface at top and inner edge. <br /> Material in these bushings must not melt or support flame. <br /> 3.5 FLEXIBLE CONNECTIONS <br /> A. Vibrating Equipment Connection: All connections to motors or other vibrating equipment or at other <br /> locations where required shall be made with not less than 12 inches of flexible liquid-tight steel conduit, <br /> using special type of connectors with strain relief fittings at both terminations of conduit, Kellems Type 074- <br /> 09 Series or accepted substitution. <br /> B. Normal Type: Flex connectors shall have insulated throat and shall be T & B 3100 Series or accepted <br /> substitution. <br /> C. Angle Type: Use angle connectors wherever necessary to relieve angle strain on flex conduit. <br /> D. Transformer Connection: Connections to dry type transformers shall be made with flexible conduit. <br /> 3.6 EXPANSION FITTINGS <br /> A. Installation: Provide expansion fittings in each conduit run wherever it crosses an expansion joint. Install <br /> the fitting on one side of the joint with its sliding sleeve end flush with joint, and with a length of bonding <br /> jumper in expansion equal to at least three times the normal width of joints. <br /> B. Location: Provide expansion fittings in each conduit run which is mechanically attached to separate <br /> structures to relieve strain caused by shift on one structure in relation to the other. <br /> C. Length: Provide expansion fittings in straight conduit runs above ground which are more than one hundred <br /> feet long. <br /> 3.7 ELECTRICAL METALLIC TUBING <br /> A. Location: Install Electrical Metallic Tubing (thin wall) inside buildings, above the ground floor where not <br /> subject to mechanical injury. <br /> B. Handling: All cut ends shall be reamed to remove rough edges. <br /> 3.8 PVC CONDUIT <br /> A. Ground Conductor Installation: All Individual bare copper ground conductors (i.e. service, transformer, or <br /> lightning protection grounds) shall be installed in PVC conduit. <br /> END OF SECTION <br /> Heartland Health Care Center of Zephyrhills-3181 16110-7 DE No 217032 <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
