What Rcd Stands for?

An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire.

What does the R stand for in RCD?

Acronym. Definition. RCD. Rotating Control Device (oil engineering)

How does RCD work?

RCDs are designed to disconnect the circuit if there is a leakage current. ... RCDs operate by measuring the current balance between two conductors using a differential current transformer. This measures the difference between current flowing through the live conductor and that returning through the neutral conductor.
