A ground fault circuit interrupter or rcd trips when the is leakage current to ground

In no fault condition the active and neutral conductor emf's cancel each other out in ground fault condition the emf's become unbalanced resulting in a small voltage being inducted into a toroidal coil which activates a internal trip relay resulting in disconnection of supply domestic rcd's are generaly set to trip at 30ma to ground

What is the GFCI?

The Ground Fault Circuit Interrupter (GFCI) is an electrical device designed to protect against electric shock by quickly cutting off power to a circuit if it detects a ground fault, such as current leakage. It is commonly used in areas where water and electricity may come into contact, such as bathrooms, kitchens, and outdoor outlets.

How do you wire a GFI breaker?

To wire a GFI (Ground Fault Circuit Interrupter) breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, attach the breaker to the panel and turn the power back on.


What is A mini circuit breaker that responds to shorts or contact with water?

A ground fault circuit interrupter (GFCI) is a mini circuit breaker that responds to shorts or contact with water. It monitors the flow of electricity in a circuit, and if it detects a ground fault (such as water contacting the electrical system), it automatically shuts off the power to prevent electric shock.
