Which outcome occurs when a ground fault circuit interrupter (GFCI) detects milliamps leakage to ground?

💡 Explanation

When a GFCI senses a small current leaking to ground it trips, opening the circuit because the differential transformer detects an imbalance between outgoing and return currents. Therefore immediate disconnection occurs, rather than voltage increase, capacity reduction, or delayed alarm, which require alternative conditions/circuit designs.
