If a GFCI detects an imbalance, what action does it take?

Explanation:
The key idea is that a GFCI watches the current on the hot and neutral conductors and expects them to be equal. If some current leaks away—usually through a person to ground—the currents become unbalanced. In that case, the GFCI quickly trips the switch and opens the circuit, cutting power to reduce the risk of shock. It’s not about grounding the equipment, bypassing the fault, or trying to re-balance the currents; it’s about interrupting the circuit when leakage is detected. After the fault is fixed, the device can be reset to restore power.
