Someone shoot me now, my boss wants to know where the requirement is to have cable going to VFD's being VFD cable (XLPE and perhaps shielding of some sort). I told him I know it is a general requirement in Article 110 (110.3). He was looking for a more specific requirement. I told him I don't think there is one. I couldn't find one...is there such a more detailed requirement in the NEC other than it violates basic engineer principals cause I know the insulation will break down over time. These will be for a 125HP and a 500HP VFD.
