Class Information
Number: 322
Name: Electricity: single generator systems >
Description: This is the Generic Class for: Single electric energy generators for supplying single load circuits, there being means to regulate or control the generator output, which means may be electrical or nonelectrical and may act in the prime mover for the generator, the power transmission means between the generator prime mover and the generator, the generator, or the armature (output) circuit of the generator, or any combination thereof.
