E. INSULATION TESTS 1. All devices that are not rated to withstand the 500V megger potential shall be disconnected prior to the megger tests. ' 2. Megger insulation resistances of all 600 volt insulated conductors using a 500 volt megger for thirty seconds. Make tests with circuits installed in conduit and isolated from source and load. Each conductor shall be meggered conductor to conductor and conductor to ground. These tests shall be made on cable after installation with all splices made up and terminators installed but not connected to the equipment. 3. Megger insulation resistances of all 480 VAC motor leads using a 500 volt megger for thirty seconds. Make these tests with motors installed in place and not connected to any other wiring. Each motor lead shall be tested conductor to ground. 4. Each megger reading shall not be less than 10 Meg-ohms resistive. Corrective action ' shall be taken if values are recorded less than 10 Meg-ohms. F. PUMP CONTROL TESTS 1. Remove motor overload heaters from each motor starter. In case the motor overload heaters are fed by current transformers, the motor conductors shall be removed and insulated away from the load lugs of the motor starter. 2. During these tests, simulate all local and remote control operations. 3. Verify the pump control circuits are wired and operate as shown on the elementary diagrams. Check the indicator lights, alarm lights, hourmeters, selector switches, alarm contacts, power fail relays, overloads, etc. for proper operation. ' 4. Reinstall all heaters and all wiring removed for this test. G. PHASE ROTATION TESTS 1. Check connections to all equipment for proper phase relationship. During this test, disconnect all devices which could be damaged by the application of voltage or reversed phase sequence. Three phase equipment shall be tested for the phase sequence "ABC" front to back, left to right, and top to bottom. ELECTRICAL ' 16000 - 53
