Which outcome occurs when a large industrial motor overheats coincident with brief power interruption, leading to breaker trip?

💡 Explanation

The heated motor draws locked-rotor current, exacerbated by simultaneous restarts after brief power loss; because inverse-time characteristics of breakers mean that the downstream breaker may fail to trip faster than its upstream cousin during sudden high-current inrush situations, therefore potentially leading to cascading failures, rather than local shutdowns.
