Choosing between ABC 6DZ and Cummins QSK38-G4

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 ABC 6DZ has the higher headline kVA rating in this pair, but site conditions and duty cycle can still change the final recommendation.
