Choosing between Caterpillar G3408 and MAN E 3262 E302

Use this comparison as an engineering shortlist, then confirm the complete generator package against load profile, voltage, 50/60 Hz frequency, duty class, emissions rules, cooling margin, altitude, ambient temperature, enclosure design, controller features, and alternator sizing. The MAN E 3262 E302 has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
