For most industrial and commercial applications, engineers use the specified by international standards like IEC 60364-5-54 or BS 7671. This formula calculates the minimum cross-sectional area (CSA) required to withstand the heat generated by a short-circuit.
In jurisdictions following the National Electrical Code (NEC), grounding cable size is often selected from pre-calculated tables based on the circuit's overcurrent protection rating or the size of the phase conductors. how to calculate Earthing conductor size
Two main methods:
⚠️ For equipment grounding conductors (EGC), use based on overcurrent device rating.
🔁 Repost to help someone avoid a melted ground wire.
