Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used as a standalone board without generator-specific design
General control panels and boards fall under 8537 unless proven principally for generators
If classified with electric motors rather than generators
Parts must be principally for 8502 generators; motor-specific parts go to 8501
If imported as part of a complete power supply converter assembly
Static converters have separate classification even if used in generator sets
