City of Everett 26 28 16 - 8 <br /> Inductive Charging Infrastructure for Everett Transit <br /> d. Perform insulation resistance tests on control wiring with respect to ground. <br /> Applied potential must be 500 V(dc) for 300 V rated cable and 1000 V(dc) <br /> for 600 V rated cable. Test duration must be one minute. For units with <br /> solid state components, follow manufacturer's recommendation. Insulation <br /> resistance values may be no less than 2 M S2. <br /> e. Determine the following by primary current injection: <br /> 1) Long-time pickup and delay. Pickup values must be as specified. Trip <br /> characteristics may not exceed manufacturer's published time-current <br /> characteristic tolerance band, including adjustment factors. <br /> 2) Short-time pickup and delay. Short-time pickup values must be as <br /> specified. Trip characteristics may not exceed manufacturer's <br /> published time-current characteristic tolerance band, including <br /> adjustment factors. <br /> 3) Ground-fault pickup and time delay. Ground-fault pickup values must <br /> be as specified. Trip characteristics may not exceed manufacturer's <br /> published time-current characteristic tolerance band, including <br /> adjustment factors. <br /> 4) Instantaneous pickup. Instantaneous pickup values must be as <br /> specified and within manufacturer's published tolerances. <br /> f. Test functionality of trip unit by means of primary current injection. Pickup <br /> values and trip characteristics must be as specified and within <br /> manufacturer's published tolerances. <br /> g. Perform minimum pickup voltage tests on shunt trip and close coils in <br /> accordance with manufacturer's published data. Minimum pickup voltage of <br /> shunt trip and close coils must be as indicated by manufacturer. <br /> h. Verify correct operation of auxiliary features such as trip and pickup <br /> indicators; zone interlocking; electrical close and trip operation; trip-free, <br /> anti-pump function; and trip unit battery condition. Reset trip logs and <br /> indicators. Investigate units that do not function as designed. <br /> i. Verify operation of charging mechanism. Investigate units that do not <br /> function as designed. <br /> 3. Test and adjust controls, remote monitoring, and safeties. <br /> E. Nonconforming Work: <br /> 1. Enclosed switches and circuit breakers will be considered defective if they do not <br /> pass tests and inspections. <br /> 2. Remove and replace defective units and retest. <br /> F. Collect, assemble, and submit test and inspection reports. <br /> 1. Test procedures used. <br /> 2. Include identification of each enclosed switch and circuit breaker tested and <br /> describe test results. <br /> 3. List deficiencies detected, remedial action taken, and observations after remedial <br /> action. <br /> G. Manufacturer Services: <br /> 1. Engage factory-authorized service representative to support field tests and <br /> inspections. <br /> 26 28 16 - 8 ENCLOSED SWITCHES AND CIRCUIT BREAKERS <br />
