I’ve come across specs referencing grounding classes from Japanese customers, i.e A class grounding, D class grounding.
Googling doesn’t turn up much – it appears that this class is related to the allowable impedance in the ground path (10 Ohms or less for class A or C, 100 Ohms or less for class D). Does anyone have more information on this?
