Which outcome occurs when the inrush current threshold is exceeded following start-up of a large industrial induction motor?

A)nuisance tripping of circuit breaker
B)motor runs at reduced speed
C)localized winding hot spot formation
D)failure of overcurrent protection relay

💡 Explanation

Nuisance tripping occurs because the magnetic inrush creates a transient overcurrent that mimics a fault, activating the circuit breaker's instantaneous trip setting. This occurs therefore immediately trips the breaker, rather than allowing normal operation; sustained overload protection isn’t triggered.
