← TechnologyWhich outcome occurs when a ground fault circuit interrupter detects imbalance in a single-phase AC circuit?
A)Circuit automatically de-energizes rapidly✓
B)Frequency shifts outside acceptable tolerance
C)Harmonic distortion increases significantly
D)Current increases exceeding rated capacity
💡 Explanation
When a ground fault occurs, the GFCI detects a current imbalance between the supply and return conductors, which activates the shunt trip mechanism because an unintended path- to-ground has been established. Therefore circuit de-energizes itself rapidly rather than a distortion. increased current, or tolerance shifts which depend on overload or inductive circuits.
