Generator & Power SizingEvent & Production
Sum equipment wattage and inductive loads to calculate total apparent power (kVA) and recommend stable generator sizing with safety headroom.
Generators should never continuously run at over 80% capacity. Safe system setups require apparent power calculations (kVA) to accurately size reactive loads like heavy sound subwoofers or heavy lighting transformers.
