Scope of protection:
Electric shock protection: GFCI is mainly used to protect people from electric shocks, especially in humid environments or places in contact with water, such as bathrooms and kitchens.
Fault detection: Detect the short circuit and ground fault in the circuit, and interrupt the circuit in time.
How it works:
Current monitoring: GFCI continuously monitors the current of the hot and neutral lines in the circuit.
Difference detection: Compare the current of the hot line and the neutral line. If the difference exceeds the set threshold (generally 5 MA), it is judged as leakage.
Quick disconnect: As soon as leakage is detected, GFCI immediately interrupts the circuit to prevent current from passing through the body.
Main parts: induction coil is responsible for detecting current difference, trigger cuts off the circuit when the difference exceeds the standard.
Through its efficient working principle, GFCI provides important electrical safety in homes and public places
