Power converter classification
(OP)
The NEC considers equipment with nominal voltage less than 600V and over 600V.If we use a VFD with power converter, we have 480 VAC as the input nominal voltage, however, the system operates with DC bus voltage over 600 VDC. What should be classification of such system from NEC standpoint?
