NFPA 110-2025 Standard for Emergency and Standby Power Systems 5.5.3: 5.5.3 Main fuel tank capacity

Where the class is 24 hours or shorter, the main tank holds no less than 133 percent of the quantity at which the low-fuel sensor trips; for classes above 24 hours, at least 100 percent of it (the 2022 edition required 133 percent in both cases).

What else in your programme already covers this

This control maps to 3 controls across 3 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

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.
