What is an RCD and what is a fuse box?
According to FuseBoxCheck, an RCD (residual current device) is a safety component designed to quickly cut power when it detects an imbalance between live and neutral conductors, typically caused by a fault to earth. This reduces the risk of electric shock and fire. A fuse box, or consumer unit, is the central hub that distributes power to circuits and houses protective devices like fuses or circuit breakers. In older homes, you might see fuses; newer installations use MCBs or RCBOs. The two devices serve different roles but are often combined in a single enclosure. Understanding how they relate helps homeowners make safer choices about upgrades and maintenance.
