VISUAL TEST S/N ITEM(S)STATUSDoneNotDoneDate 1. Check the equipment tag number is correct against the tag number shown on the One Line Diagram and the equipment data sheet.2. Check the nameplates against, the One Line Diagram and theequipment data sheet.3. Verify that all internal control and instrumentation terminations aresecurely and properly connected.4. Verify that all control wires terminal markings are properly and clearlyprinted. No visible signs of hand markings.5. Verify that the number of sections is correct.6. Verify that all components (e.g. MCB, CT, CPT/VT, relays, fuses, etc.)are installed properly.7. Verify that the incoming power connections / lugs are properly secured8. Verify that control wirings are correctly and properly identified.9. Verify that the cubicle is clean and free from debris. B. MECHANICAL TEST 10. Check switch to insure positive interlock between normal and alternatesources.11. Check tightness of all cable connections and bus joints.12. Perform manual transfer operation.13. Verify that all internal control and instrumentation terminations aresecurely and properly terminated. C. ELECTRICAL TEST 14. Verify continuity of all power and control leads.15.

The presence of the column headed 'dc withstand' does not imply any requirement for a dc withstand test on acequipment. The column is given as a reference only for those using dc tests and represents values believed tobe approximately equivalent to the corresponding power frequency withstand test values specified for each classof bus. 2. Direct current withstand tests are recommended for flexible bus to avoid loss of insulation life that may resultfrom the dielectric heating that occurs with rated frequency withstand testing. 3. Because of the variable voltage distribution encountered when making 'dc withstand tests' and variances inleakage currents associated with various insulation systems, the manufacturer should be consulted for recommendations before applying 'dc withstand tests' to this equipment.
