Where each walk sits in the schedule
- Standby generator set quarterly maintenance checklistquarterly
- Every quarter, independent of the weekly automatic exercise cycle run by the building's own controls. Run by: The generator service tech on the contracted quarterly visit.
- Standby generator set annual maintenance checklistannual
- Once a year, scheduled with building management since it typically requires a planned load transfer or bank load. Run by: The generator service lead, often coordinated with the electrical contractor for the ATS work.
What most often fails on a standby generator set
- Battery load test skipped because voltage looked fine at rest, then the unit won't crank on a real outage.
- Coolant heater breaker found off for months with nobody noticing the block never warmed up.
- Off-load run logged as complete with no record of the actual run time or readings taken.
- Load test run at a fraction of nameplate capacity and reported as a full test.
- Coolant hoses left original past their service life because the engine 'wasn't leaking yet'.
- ATS exercised in test mode only, never proven under an actual simulated utility loss.
