What is a Residual Current Device, or RCD?

A type of electrical safety device that detects and interrupts the flow of electricity in the event of a fault, such as a short circuit or ground fault. It operates by measuring the difference in current between the live and neutral wires. If the difference exceeds a certain threshold (typically 30 mA), the RCD quickly cuts off the power, preventing electric shock.
