How to Connect an Australian RCD Circuit Breaker

In Australia, RCD (Residual Current Device) breakers are called "safety switches." This is because an RD breaker is designed to shut down electricity in the event of an imbalance of electricity between the two conductors on the circuit. If there is an imbalance in the electricity while someone is working on the circuit, it can cause a lethal shock. That's why it's important to add an RCD breaker to your home circuit system.
