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

Residual Current Devices, or RCDs, are an essential form of protection for most circuits in modern electrical installations. In this video, we explain how an RCD works and the protection they offer to electrical installations and the people who use them. http://hub.efixx.co.uk/SE-cprotection ========================================= 00:00 Schneider circuit protection series 00:20 What is a residual current device (RCD)? 00:50 What protection does an RCD provide? 02:06 Electric shock protection 0
