The Residual Current Device, or RCD, is one of the most important electrical safety devices in both the home and commercial environments. In short, an RCD protects against injury and death caused by electric shock by detecting an imbalance between the outgoing and incoming total current of a given number of circuits.

How RCD devices work. Under normal operation, when there is no magnetic field in the core, no electricity flows through the search coil (gray) or relay (blue).

Residual Current Devices (RCD) - How they work How does the test button on an RCD work when it doesnt have a connection to earth? My understanding is that what we call an RCD in the UK in the USA they call a GFCI and as you say they monitor difference between live and neutral i.e current flowing to earth, they wont trip if an insulation…

How does it work? An RCD constantly monitors the electric current flowing through one or more circuits it is used to protect. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, the RCD will switch the circuit off very quickly, significantly reducing the risk of death or serious injury.

A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock.

RCDs are a bit like transformers. By using different amounts of wire in the two coils, a transformer can change a high-voltage electric current into a low-voltage one (or vice versa). Inside an RCD, the live and neutral cables from the electric supply wrap around an iron core much like the one in a transformer.
