Which risk significantly increases when interrupting an inductive circuit with high inrush current using a mechanical switch?

💡 Explanation

When an inductive circuit with a high inrush current is interrupted mechanically, a large voltage spike occurs due to Lenz's Law attempting to maintain current flow, leading to significant electrical discharge. Therefore, arc flash and contact degradation becomes a major risk, rather than runaway, EMI, or resonance which result from different conditions.
