| Quantity represented | 8 identified units in the technical package | 2 units |
| Technical details / open items | Eight 3516E engine/product identities appear in the technical package, with machine-build dates from October through December 2024. The reviewed generator-set nameplate is dated February 2025.; Reviewed nameplate: 3,000 kW / 3,333 kVA, 0.9 PF, 480 V, three-phase, 60 Hz, 4,009 A and 1,800 RPM; wye series, six leads, Class H insulation.; Reviewed factory-order example: 3516E HPD, 3,000 ekW standby with fan, EMCP 4.2B controller, 5,000 A IEC busbar with top cable entry, AF81AVS radiator and dual electric starting.; That factory-order example specifies two 35 A battery chargers, no batteries ordered, no factory circuit breaker, non-UL-2200-listed package, no CSA selection and no seismic certification selection. Panel and decal selection is Portuguese. Match the actual order record to each selected unit.; Emissions records identify the 2024 engine family as EPA Emergency Stationary, constant speed. This is not a claim of prime/continuous duty or of suitability for a particular site's emissions permit.; The documented 3 MW rating is standby. A proposed lower output or duty change, including 2.75 MW operation, needs the selected-unit OEM/dealer rating and emissions review; no continuous rating or automatic conversion is promised. | Two units offered by J&J on October 29, 2026. The repeated tag photos document one unit, rather than two distinct serial-number records.; Photographed Caterpillar nameplate: 3516C engine model; standby duty; 2,000 kW / 2,500 kVA at 0.8 power factor. This is a standby rating; no prime or continuous output is established by the supplied tag.; Electrical nameplate: 480 V, three-phase, 60 Hz, 3,007 A and 1,800 RPM; wye, series connection with six leads.; October 2016 manufacture is shown on the photographed generator-set nameplate. Confirm the second unit’s manufacture date, ratings, electrical configuration and matching records before allocation.; Class H insulation; frame 1625; rated ambient 40 °C and altitude 1,000 m. NEMA temperature rise 125 °C by resistance; UL maximum temperature rise 135 °C by resistance.; Excitation: 56 V and 4.6 A. The supplied tag also records the alternator reactance and time-constant values, available for the engineering review.; Caterpillar identifies the 3516C model family as diesel generator sets. No unit-specific emissions tier, emissions permit suitability, load-bank result, warranty, low-hour claim or refurbishment claim is established by these photos.; Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com for unit pricing, hours, maintenance history, inspection and an itemized equipment and delivery scope. |
| Evidence reviewed | J&J technical package dated November 3, 2026: eight-unit build schedule, one reviewed factory-order record and one reviewed generator-set nameplate | J&J-supplied equipment and nameplate photos; detailed ratings verified on one photographed unit; quantity of two confirmed by J&J on October 29, 2026 |
| Technical value basis | Reviewed factory-order example and nameplate in the November 3, 2026 J&J technical package; match selected-unit records | Technical values transcribed from the photographed Caterpillar generator-set nameplate. These values apply to the documented unit; obtain the second unit’s matching nameplate before final selection. |
