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. 🔁 Repost to help someone avoid a melted ground wire
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. practical post for electrical engineers
