Why does an RCD keep tripping?

An RCD (Residual Current Device) may keep tripping for various reasons. It could be due to an overly sensitive RCD, which trips even at minor current leaks. Damage inside the consumer unit, faulty appliances, or damaged wiring can also cause trips. In some cases, insects or slugs entering plug sockets can short terminals and trigger the RCD. Additionally, water ingress or moisture in electrical components can lead to intermittent tripping.

If an RCD keeps tripping, it's essential to inspect the system, appliances, and wiring, and consult a professional if the issue persists.
