Which operational outcome occurs when exceeding a transformer's inrush tripping threshold during grid energization?

💡 Explanation

Nuisance breaker tripping occurs because the transformer inrush current triggers the breaker's magnetic trip unit meant for short circuits; therefore, the breaker opens, rather than allowing the transient current to subside through normal core magnetization.
