Technology

Which outcome occurs when a circuit breaker trips in a three-phase motor control center during the operation of a pump?

A)Single-phasing motor operation occurs
B)Increased harmonic distortion propagates
C)Voltage sag immediately elevates
D)Complete system over-voltage isolates

💡 Explanation

Single-phasing occurs following breaker trip due to phase loss because the electrical motor continues running on the remaining phases rather than ceasing function, therefore potentially causing overheating, rather than harmonic distortion, sag, or over-voltage as those originate separately.
