What hazard is a ground-fault circuit interrupter primarily intended to reduce?
Correct Answer
A) Electric shock from leakage current to ground
A GFCI detects an imbalance between outgoing and returning current and interrupts the circuit to reduce ground-fault shock risk. It does not regulate voltage or cure transformer noise. Overcurrent protection is a separate function, even when combined with GFCI protection in one breaker. GFCI protection does not eliminate every possible shock hazard.
