Here’s the practical approach used worldwide (based on IEC & NEC standards). The cable must handle the full fault current long enough for the protective device to clear the fault, without its insulation melting. grounding cable size calculation

[ S = \frac{\sqrt{I^2 \times t}}{k} ]

Choosing the right grounding conductor size isn’t guesswork—it’s critical for safety and code compliance. Undersize it, and a fault could vaporize the cable before the breaker trips. Oversize it, and you waste money. grounding cable size calculation
