💡 Always consult a licensed electrician and local building codes before finalizing any electrical installation. If you’d like to narrow this down, let me know: Is this for a residential or industrial application? Which electrical code do you follow (NEC, IEC, etc.)? // Total Derating Factor let totalDerating = tempFactor

Different materials like PVC or XLPE have different thermal limits. XLPE, for example, can typically handle higher temperatures (90°C) than standard PVC (70°C). Different materials like PVC or XLPE have different
