WebMay 13, 2024 · RCDs work by measuring the balance of electrical currents between two conductors using what’s called a “differential current transformer.”. Basically, a residual current device uses a detector to track how much electricity is sent out against how much comes back through and checks to make sure the two amounts match. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock. … See more RCDs are designed to disconnect the circuit if there is a leakage current. In their first implementation in the 1950s, power companies used them to prevent electricity theft where consumers grounded returning … See more The diagram depicts the internal mechanism of a residual-current device (RCD).
