Specifications per Cummins' official "Diesel Generator Set QSB5.9 Series" specification sheet (print code PSBU/025/QSB5.9/Revision-03, 11-2022). Verified via bore x stroke x cylinder-count vs. stated displacement cross-check (102x120mm x 6-cyl = 5.88L, matched exactly). All ratings are Prime only -- no separate Standby rating stated. Unlike Cummins' X2.6 series (25-40 kVA) processed separately, this document states "CPCB II Compliant" (visible badge on the product photo), not CPCB IV+ -- same brand, different tier, consistent with its older Nov-2022 print code predating the July 2023 CPCB IV+ mandate. noise_db (75) is the brochure's stated design-compliance ceiling ("<=75 dBA @1m at 75% load"), not a certified per-unit test result. Dimensions/weight are the "Typical Enclosed Genset Dimensions" table figures (full canopy, both ratings share the exact same 2528kg wet weight and canopy size despite different HP), not the smaller bare engine-only dimensions also listed in the Engine Specification table. Fuel consumption assumes 0.85 specific gravity diesel per the brochure's own footnote.
