Get to grips with everything you need to know about RCD testing in our comprehensive guide. Discover its importance, understand the process, and learn how to stay compliant.
A residual current device (RCD) monitors the current flow of home appliances. If it detects an imbalance, even as small as 4-6 milliamps, the RCD will instantly trip to cut power. This helps prevent electric shock, as leakage over ten milliamps can be hazardous. The RCD provides vital protection where traditional fuses or circuit breakers may fail. Installing RCDs in your electrical system adds an important safety layer for appliances that could develop faults over time.
