The standard mandates that a generating set must be capable of supplying the maximum load current and withstand the inrush currents of loads (motors, transformers, etc.). Specifically:
The standard references (Reciprocating internal combustion engine driven alternating current generating sets) for performance classes (G1, G2, G3, G4). Installers must match the generator class to the load sensitivity. iec 60364 part 551 pdf
"Exactly," Arthur replied. "The IEC 60364 series is the international bible for wiring regulations. Part 5-551 is the chapter on independence. It’s what keeps the lights on in the elevators and the fire pumps running without turning the whole building's copper into a live trap". The standard mandates that a generating set must
