Chapter 8: Routine maintenance and operational testing – NFPA 110-2025 Standard for Emergency and Standby Power Systems

NFPA 110-2025 Standard for Emergency and Standby Power Systems 8.4.1: 8.4.1 Weekly or monthly inspection and monthly exercise

Level 1 EPSs and all their components are inspected weekly and Level 2 EPSs monthly (the 2025 differentiation), and the EPSS is exercised under load at least monthly. Use of the set for standby service or peak shaving may replace a scheduled run if it is recorded like a test.

What else in your programme already covers this

This control maps to 6 controls across 4 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

  • 17.81-17.83 Monthly on-load generator test of at least one hour including changeover
  • 17.92 Reduced test frequency only where parallel operation with the PES exists
  • 17.93-17.95 Weekly visual inspection and three-monthly functional tests of primary and secondary supplies
  • 8.4.1-8.4.2 8.4.1 and 8.4.2 Monthly inspection and inspection content

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
