Construction Diesel Generator Sizing Guide: kW, kVA, Starting Loads, and Jobsite Power

Construction sites need temporary power for lighting, offices, pumps, welders, cranes, concrete equipment, compressors, chargers, heaters, and many other loads. Choosing a diesel generator by simply adding nameplate kilowatts can lead to voltage dips, nuisance trips, excessive fuel use, or a machine that spends most of its life lightly loaded. Correct sizing requires understanding the difference between kW and kVA, continuous and standby ratings, power factor, motor starting current, load seque.
