Yes, all A GFI trips if the current in the live wire does not match the current in the neutral wire. It is assumed that in that case that current leaked to ground somewhere, i.e. a “ground fault” though it could have shorted to another circuit rather than ground.In the UK known as an ELCB (Earth Leakage Circuit Breaker)Tripping on excessive current protects the wiring from overheating, possibly causing a fire.One possibility for a ground fault is current passing through a person to ground, so the GFI might save them from a serious shock or electrical burn....
