An RCCB (Residual Current Circuit Breaker), also known as an RCD (Residual Current Device), is crucial in an electrical installation for several reasons: 1. Prevents Electric Shocks:RCCBs detect and disconnect the power supply if they sense a leakage current caused by faults like touching a live wire. This protects people from severe electric shocks. 2. Protects Against Fire Hazards:Leakage currents, especially through faulty wiring or appliances, can cause overheating and lead to electrical fir

97K views · 2.2K reactions | Many homes overlook a crucial electrical component: the Residual Current Circuit Breaker (RCCB). It detects current flowing out of the loop, tripping in microseconds to cut power and protect against electric shock. This device gives someone receiving a shock a second chance. #topheightselectricals #viral #fyp #reel #RCCB | Topheights Electricals and Electricians | Facebook
