City of Everett 26 05 26- 9 <br /> Inductive Charging Infrastructure for Everett Transit <br /> 1. After installing grounding system but before permanent electrical circuits have <br /> been energized, test for compliance with requirements. <br /> 2. Inspect physical and mechanical condition. Verify tightness of accessible, bolted, <br /> electrical connections with calibrated torque wrench in accordance with <br /> manufacturer's published instructions. <br /> 3. Test completed grounding system at each location where maximum ground- <br /> resistance level is specified, at service disconnect enclosure grounding <br /> terminal, at ground test wells, and at individual ground rods. Make tests at <br /> ground rods before conductors are connected. <br /> a. Measure ground resistance no fewer than two full days after last trace of <br /> precipitation and without soil being moistened by means other than natural <br /> drainage or seepage and without chemical treatment or other artificial <br /> means of reducing natural ground resistance. <br /> b. Perform tests by fall-of-potential method in accordance with IEEE Std 81. <br /> c. Excessive Ground Resistance: If resistance to ground exceeds specified <br /> values, notify Architect promptly and include recommendations to reduce <br /> ground resistance. <br /> 4. Prepare dimensioned Drawings locating each test well, ground rod and ground- <br /> rod assembly, and other grounding electrodes. Identify each by letter in <br /> alphabetical order, and key to record of tests and observations. Include number <br /> of rods driven and their depth at each location, and include observations of <br /> weather and other phenomena that may affect test results. Describe measures <br /> taken to improve test results. <br /> D. Nonconforming Work: <br /> 1. Grounding system will be considered defective if it does not pass tests and <br /> inspections. <br /> 2. Remove and replace defective components and retest. <br /> E. Collect, assemble, and submit test and inspection reports. <br /> 1. Report measured ground resistances that exceed the following values: <br /> a. Power and Lighting Equipment or System with Capacity of 500 kVA and <br /> Less: 10 Q. <br /> b. Power and Lighting Equipment or System with Capacity of 500 to <br /> 1000 kVA: 5 Q. <br /> c. Power and Lighting Equipment or System with Capacity More Than <br /> 1000 kVA: 3 O. <br /> d. Manhole Grounds: 10 Q. <br /> 3.5 PROTECTION <br /> A. After installation, protect grounding and bonding cables and equipment from <br /> construction activities. Remove and replace items that are contaminated, defaced, <br /> damaged, or otherwise caused to be unfit for use prior to acceptance by Owner. <br /> END OF SECTION 260526 <br /> 26 05 26 - 9 GROUNDING AND BONDING FOR ELECTRICAL SYSTEMS <br />
