Which consequence results when exceeding arc flash protection thresholds?

💡 Explanation

When an arc flash incident happens, the immense heat causes rapid dielectric breakdown because atoms become ionized; this is worsened without proper `arc quenching`. Therefore insulation fails dramatically, rather than triggering immediate breaker faults or similar effects in core saturation.
