Generator compliance resources
General overview — verify against the governing code and your AHJ. The intervals and requirements described here reflect a good-faith reading of NFPA 110 / CMS Life-Safety requirements and can vary by code edition, jurisdiction, accreditor, and equipment. This is not legal or engineering advice and may not be the exact requirement for your facility — always confirm the tests and intervals that apply to you with your Authority Having Jurisdiction (AHJ) and accreditor. StandbyProof readies your records; it does not determine your requirements.
Plain-English guides to emergency and standby generator testing — what the codes require, how often, and what surveyors ask for. No jargon, no fluff.

The complete schedule: weekly inspection, monthly load test, annual, and 3-year endurance — in one table.
The monthly load test →
The 30% / 30-minute rule, the 20–40 day window, and the under-load trap that triggers a load-bank test.
CMS testing for hospitals →
How NFPA 110 and CMS emergency-preparedness rules stack up, including the 96-hour fuel expectation.
A note on these guides. They're general educational overviews of common NFPA 110 / CMS intervals — not compliance or legal advice, and not your Authority Having Jurisdiction. Your AHJ, accreditor, state and local amendments, and equipment manufacturer can set different requirements. Always confirm the specifics for your facility with your compliance officer.
Turn these rules into a schedule that runs itself
StandbyProof builds your generators' test schedule, reminds you before each is due, and produces the inspection-ready packet on demand.
