Residual Current Circuit Breakers (RCCBs) play a vital role in ensuring electrical safety in our homes, offices, and industries. These devices are often overlooked but are crucial in preventing electrical accidents and fires. In this article, we will delve into what RCCBs are, how they work, and why they are indispensable in modern electrical systems.
What is an RCCB?
An RCCB, or Residual Current Circuit Breaker, is an electrical device designed to protect people and property from electric shock and electrical fires. It detects and interrupts abnormal electrical currents that flow along unintended paths, such as through a person’s body or into the ground, rather than the intended circuit. This is especially important in situations where a fault in the electrical system could have life-threatening consequences. How Does an RCCB Work? RCCBs operate on the principle of detecting the difference between the current entering an electrical circuit and the current returning from it. In a properly functioning electrical system, these two currents should be equal, indicating that electricity is flowing safely within the circuit.
