Sequence of Job Steps

List basic sequence of steps from start to finish

Loto and ZVV, turn off all relevant breakers and apply lockout/tagout devices to prevent unauthorized re-energizing. Use Zero Voltage Tester (ZVV) multimeter to confirm there is no voltage before performing any work. Swap circuits 12 and 13 in wireway which is fed from panel 316a21a to correctly reflect panel schedule and devices. Troubleshooting may require toggling breakers on and off. Once work is complete, remove lockout/tagout device(s) and re-energize. Verify circuits are feeding the correct devices according to panel schedule.
