What is a generator inspection checklist?
A generator inspection checklist is a structured list of tasks and checks to perform before operating a generator. It helps operators, electricians and site supervisors confirm that the generator is mechanically sound, electrically safe, properly earthed and compliant before it is put under load. The checklist should be completed before each use or at the start of each shift and is a key preventive measure to catch faults, such as fluid leaks, damaged cables or tripped breakers, before they create a safety incident or equipment failure.
Generator inspections are required on most Australian construction, mining and industrial sites and align with obligations under WHS legislation, AS/NZS 3000 (wiring rules), AS/NZS 3760 (test and tag) and site-specific electrical safety management plans. Generators present both electrical and mechanical hazards including electrocution from faulty earthing or damaged cables, fire from fuel leaks or overheating, carbon monoxide poisoning from exhaust in enclosed spaces, and noise exposure. A thorough pre-use inspection addresses all of these risk categories in a single structured process.
AS/NZS 3010:2017 (Electrical installations: Generating sets) sets out specific requirements for the installation, earthing and protection of generators used to supply electrical power. Section 5 of the standard addresses earthing systems, while Section 6 covers protection against overcurrent and earth fault. Under WHS Regulations 2011, Chapter 5, Part 5.1, a person conducting a business or undertaking (PCBU) must ensure that plant is maintained so it is without risk to health and safety and that inspections are carried out by a competent person. Failure to maintain a documented inspection regime for generators can result in enforcement action from the WHS regulator, void insurance coverage for electrical incidents, and expose the PCBU to prosecution where a foreseeable hazard was not controlled.

Benefits of using this generator inspection checklist
- Electrical safety: identify damaged cables, faulty RCDs and earthing issues before personnel connect loads.
- Prevent equipment failure: catch low oil, coolant leaks or worn belts before they cause a breakdown mid-shift.
- Fire and fuel risk management: confirm spill containment is in place and fuel lines are secure before start-up.
- Compliance: meet WHS, electrical safety and principal contractor requirements and demonstrate due diligence.
- Consistency and accountability: a standardised checklist ensures critical items are never skipped across operators or shifts.
- Maintenance recordkeeping: build a history of run hours, fault trends and service intervals tied to each generator asset.

What to include in a generator inspection checklist
This generator inspection checklist covers 9 key areas:
- Generator details: asset ID/serial, make/model, site/location, date, inspector name, current run hours and next service due.
- External and physical condition: housing, ventilation, frame and mounting, exhaust, fuel system, spill containment bund, labels and general cleanliness.
- Fluids and levels: engine oil, coolant, fuel level and visible leaks.
- Engine and mechanical: air filter, drive belts, cooling fan and guard, battery, hoses, start-up behaviour and unusual noises or vibration.
- Electrical output and controls: output voltage and frequency, control panel indicators, circuit breakers/MCBs, RCD/safety switch (push-button test), earth/ground connection, cables and leads, outlet sockets, auto-start/transfer switch, emergency stop and hour meter reading.
- Safety equipment: fire extinguisher, PPE requirements and exclusion zone.
- Compliance and documentation: test and tag currency, service record, operating manual on site and any permits or electrical safety compliance documentation.
- Overall result: Pass/Fail with a defect register for failed items.
- Declaration and signatures: inspector sign-off and supervisor/reviewer acknowledgement.
How to use this generator inspection checklist
- Record generator details (asset ID, make/model, run hours, site and date) at the top of the form.: Note the asset ID or serial number, make and model, current run hours from the hour meter, site location and the date. This links the inspection to the specific generator and its maintenance schedule.
- Inspect each item in sequence - working from external/physical through fluids, engine, electrical output and controls, then safety and compliance. Mark Pass, Fail or N/A for each item.: Check housing and frame for damage, verify fuel and oil levels, inspect belts and hoses, test the RCD with the push-button test, confirm earthing is connected, check all outlet sockets and cables for damage, and verify the emergency stop button functions correctly.
- For any Fail item, add a note describing the fault. Do not operate the generator until the fault has been assessed and rectified or formally approved.: Describe the fault clearly so a maintenance technician or electrician can assess it without re-inspecting. Tag the generator as out of service if the fault poses an electrical safety or fire risk. Critical faults such as faulty RCDs or damaged earthing must be rectified before use.
- Complete the overall result (Pass/Fail) and record all failed items in the defects register with the action taken and who it was reported to.: Summarise all failed items in the defects table at the bottom of the form. Record the action taken (repaired on site, reported to maintenance, generator taken out of service) and the name of the person the fault was reported to.
- Sign and date the declaration. The supervisor or reviewer signs the acknowledgement section.: Your signature as inspector confirms you have completed the inspection honestly and accurately. The supervisor signature acknowledges the findings and confirms any corrective actions have been raised or completed.
- Keep the completed form with the asset record or file it as required by your site procedures. Save as PDF using Print then Save as PDF in your browser.: Store the completed checklist against the generator asset record for maintenance history and audit purposes. Digital forms in MapTrack automatically link to the asset, building a complete inspection and service history over time.
In MapTrack, you can digitise safety inspections and compliance forms. Each submission is stored as a timestamped PDF against the asset record.

Back to download formHow often should you complete this checklist?
Complete a generator inspection before each use or at the start of each shift. For standby or hire generators that are infrequently used, inspect the unit before starting even if it has been sitting idle - fluid levels drop, batteries discharge and pests can damage wiring during storage.
Beyond daily pre-use checks, generator manufacturers typically require service intervals at 250, 500 and 1,000 run hours (or annually, whichever comes first). Site procedures, the principal contractor's electrical safety management plan or applicable Australian Standards may also specify additional periodic inspection frequencies. Follow whichever interval is most stringent. Organisations managing multiple generators should maintain a centralised register that tracks each unit's inspection dates, run hours and next service milestone.
