  • Is the generator housing, enclosure panels, and exterior free from visible damage, corrosion, or vandalism?
  • Are vibration isolation pads and mounting hardware intact and showing no signs of excessive wear?
  • Is the generator nameplate and identification tag legible and securely attached?

Fuel System Inspection

Inspect the fuel storage tank, supply lines, filters, and related components for leaks, capacity, and compliance.

  • Is the fuel tank level at or above the minimum required level (minimum 75% capacity for emergency systems)?
  • Are all fuel supply and return lines free from visible leaks, cracks, or deterioration?
  • Is the fuel filter in good condition and within the manufacturer-recommended replacement interval?
  • Is secondary containment present and free of fuel, water, or debris accumulation?
  • Has fuel been tested or treated for microbial contamination and water accumulation within the past 12 months?
  • Is the fuel tank vent pipe clear, properly directed, and free of blockage?

Engine Fluids and Cooling System

Check engine oil, coolant, and all fluid levels, as well as the cooling system for proper function.

  • Is the engine oil level within the manufacturer-specified operating range?
  • Is the engine coolant level adequate and free from discoloration or contamination?
  • Is the coolant temperature within the manufacturer-specified range during operation?
  • Are radiator fins, cooling fans, and hoses free from damage, blockage, or excessive wear?
  • Is the block heater operational and maintaining engine temperature above 90°F for cold-start readiness?

Electrical Output and Connections

Verify generator output voltage, connections, transfer switch, and load bank test compliance.

  • Is the Automatic Transfer Switch (ATS) functional and tested within the required interval?
  • Are generator output voltage and frequency within acceptable tolerances (±10% voltage, ±5% frequency)?
  • Are all electrical connections, terminals, and bus bars tight, clean, and free of corrosion or arcing marks?
  • Has a load bank test been performed within the past 12 months at a minimum of 30% rated load?
  • Are all generator output breakers and distribution panels labeled and accessible?

Exhaust System and Emissions Compliance

Inspect the exhaust system integrity and verify compliance with EPA emissions requirements for stationary engines.

  • Is the exhaust system free from cracks, leaks, or signs of exhaust gas intrusion into occupied spaces?
  • Are exhaust outlets directed away from building air intakes, windows, and occupied areas per code?
  • Is the exhaust silencer or muffler in good condition and securely mounted?
  • Are EPA Tier 4 emissions standards compliance records and engine certifications on file and current?
  • Is visible smoke or excessive soot emission absent during generator operation or test?

Battery and Starting System

Inspect the generator starting batteries, charger, and control panel for operational readiness.

  • Are starting batteries free from corrosion, cracks, bulging, and electrolyte leakage?
  • Is battery voltage within the manufacturer-specified charge level (typically 12.4–12.8V per 12V battery)?
  • Is the battery charger operational with correct float voltage displayed?
  • Are battery terminals clean, tight, and protected from accidental short-circuit?
  • Are battery replacement dates recorded and batteries within the manufacturer's service life interval?

Control Panel and Alarm Systems

Verify the generator control panel, monitoring systems, and alarm functions are operational and compliant.

  • Is the generator control panel free of active fault codes, alarms, or warning indicators?
  • Are all required generator alarms (low oil, high temp, overcrank, overspeed) functional and tested?
  • Is remote monitoring or building automation system integration active and communicating correctly?
  • Are maintenance logs, test records, and inspection reports stored on-site and accessible for review?
  • Were any deficiencies, corrective actions, or parts replacements identified during this inspection?
