Is there something in the NEC that defines the spacing requirements between exposed 4.16kV conductors and ground. For example what is the spacing requirement between 4.16kV busbars between phases, and also between a bus/termina/lug and surrounding cabinet?
Is there a seperate table of values for each voltage or is there a standard multiplier?
