Which consequence results when inductive kickback exceeds breaker capacity?

💡 Explanation

Breaker contact welding occurs because inductive kickback generates extreme current, exceeding the breaker's Interrupting Rating; therefore, contacts fuse shut rather than opening safely, and this promotes thermal runaway because the breaker cannot perform its basic function.
