The NFPA 110 generator checklist: interactive, printable PDF, and Excel

Work the weekly-to-annual PM checklist right here with live progress, then take the record with you: a printable PDF form and an Excel (XLSX) log template, free. The enforceable intervals come from the adopted edition and your AHJ.

What a generator PM checklist covers

A generator PM checklist built around NFPA 110 practice runs on four cadences: a weekly visual inspection, a monthly exercise and transfer test under load, quarterly maintenance, and an annual service that adds fluid changes, fuel testing, and a load bank test where routine loading falls short of the governing criteria. Every completed item should land in a test log with readings and initials. The enforceable intervals, loads, and durations come from the adopted edition of NFPA 110 and the authority having jurisdiction. The checklist organizes the work; it does not set the requirements.

Work the checklist

Four cadences, one unit at a time. Check items off as you confirm them; each section tracks its own progress.

Overall progress: 0 of 45 items

Progress lives on this page only and clears on refresh. For a record you can file, download the PDF or Excel below — or let PowerOps write the permanent one.

Weekly inspection

0 / 12

A documented weekly walk-around is standard practice for an emergency power supply system. Mark each item as you confirm it, and record readings in your log.

Monthly exercise & transfer test

0 / 11

Run the set under load on the monthly cadence and record the results. The loading criteria come from the adopted edition and your AHJ — record what you ran and how the unit behaved.

Quarterly maintenance

0 / 10

In addition to all weekly and monthly items.

Annual maintenance

0 / 12

In addition to all weekly, monthly, and quarterly items. Load bank duration and profile come from the adopted edition and your AHJ.

Running a load bank?

There is a matching load bank test log (planned load profile, readings under load, observations, and sign-offs) in the load bank testing guide.

Who sets the real requirements

This checklist summarizes how the industry tends to organize generator PM work. It does not reproduce NFPA 110, and it cannot: the enforceable tasks, intervals, loads, and durations depend on the system’s classification, the edition your jurisdiction adopted, and the authority having jurisdiction, with the manufacturer’s instructions layered on top. Where those sources differ, the stricter requirement governs.

For the cadence framework in plain English, see the generator maintenance schedule page. For how NFPA 110 classifies systems and structures its testing, see the NFPA 110 testing requirements guide.

Frequently asked

Is there a printable PDF version of this checklist?

Yes. The download on this page is a printable PDF form with the weekly, monthly, quarterly, and annual tasks plus a generator test log, formatted for a clipboard in the field. Enter a work email and both the PDF and the Excel edition are yours free.

Is there an Excel (XLSX) version of the generator PM checklist?

Yes. The same download includes an XLSX workbook: one sheet per cadence (weekly, monthly, quarterly, annual), a unit-information sheet, and a test-log sheet with a row per exercise or test event, for shops that keep maintenance records in spreadsheets.

Does completing this checklist make a facility NFPA 110 compliant?

No. The checklist summarizes common industry practice and helps you run a disciplined program, but compliance is judged by the authority having jurisdiction against the edition of the standard your jurisdiction adopted. The enforceable tasks, intervals, loads, and durations live there, and where the manufacturer’s instructions are stricter, the stricter requirement governs.

What intervals does NFPA 110 actually require?

It depends on the system’s classification, the edition your jurisdiction adopted, and your AHJ. The weekly, monthly, quarterly, and annual grouping here reflects how the industry tends to organize the work; treat it as a starting framework and confirm the enforceable specifics with the AHJ before you commit a schedule to a contract.

What should a generator test log record?

One row per event: the date, the type of run (weekly no-load check, monthly load transfer, load bank, or a real outage), run time, load in kW and percent of nameplate, oil pressure, coolant temperature, voltage, frequency, transfer time, and the initials of the person who ran it. Both download formats on this page include that log.

A checklist proves you have a plan. The record proves you ran it.

PowerOps turns every PM, reading, and load bank result into an attributed, append-only record per unit: the one an auditor or AHJ asks for.
