a. Inspections <br /> 11 Visual and mechanical inspections <br /> a) Inspect for physical damage, proper anchorage and <br /> grounding. <br /> b) Compare equipment nameplate data with design plans and — <br /> starter schedule. <br /> c) Compare overload setting with motor full load current for _ <br /> proper size. <br /> 2) Performed NETA acceptance testing for each piece of equipment. <br /> 3) The Contractor shall fill in, for each piece of equipment, NETA — <br /> Test Form. <br /> b. Torque Connections <br /> 1) All electrical, mechanical and structural threaded connections <br /> inside equipment shall be tightened in the field after all wiring <br /> connections have been completed. Every worker tightening — <br /> screwed or bolted connections shall be required to have and <br /> utilize a torque screwdrive rlwrench at all times. Torque <br /> connections to the value recommended by the equipment _ <br /> manufacturer. If they are not available, use NEC 110-14 for <br /> torque values as guidelines. <br /> C. Wire Insulation & Continuity Tests <br /> 1) All devices that are not rated to withstand the 500V megger <br /> potential shall be disconnected prior to the megger tests. <br /> 2) Megger insulation resistances of all 600 volt insulated conductors <br /> using a 500 volt megger for 10 seconds. Make tests with circuits <br /> installed in conduit and isolated from source and load. Each field — <br /> conductor shall be meggered conductor to conductor and <br /> conductor to ground. These tests shall be made on cable after <br /> installation with all splices made up and terminators installed but <br /> not connected to the equipment. <br /> 3) Each megger reading shall not be less than 10 Meg-ohms — <br /> resistive. Corrective action shall be taken if values are recorded <br /> less than 10 Meg-ohms.Values of different phases of conductors <br /> in the same conduit run showing substantially different Meg-ohm <br /> values, even if showing above 10 Meg-ohms shall be replaced. _ <br /> 4) Each instrumentation conductor twisted shielded pair shall have <br /> the conductor and shield continuity measured with an ohmmeter. <br /> Conductors with high ohm values, that do not match similar — <br /> lengths of conductors the same size, shall be replaced at no <br /> additional cost to the Owner. <br /> 5) The Contractor shall fill in test forms Power and Control <br /> Conductor Test Form TF1 and Instrumentation Conductor Test <br /> Form TF2 located in Appendix"A". <br /> Division III-223 NEI Phase II Water and Sewer - <br /> July 2007 CIP Nos. 7468, 7589, 7590 <br />
