Which risk increases when exceeding a transformer's breaker interrupt rating?

💡 Explanation

Exceeding interrupt rating means the arc is not extinguished, therefore increased arc flash energy is released due to excessive ionization, rather than the breaker interrupting the fault quickly & safely disconnecting the circuit.
