What is cable size for 275 kw gen-set?

The cable size for a 275 kW generator set typically depends on factors such as the voltage level, distance from the generator to the load, and the type of insulation used. For a three-phase system at 400V, a common cable size might be around 95-120 mm² (copper) or 150-185 mm² (aluminum) to ensure safe operation and minimize voltage drop. Always consult local electrical codes and guidelines, and consider using a professional electrician for accurate sizing based on specific installation conditions.
