A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore indicating current leaking to ground, or to an unint

Coordination of residual current protective devices

Such selectivity avoids the tripping of any RCD, other than that immediately upstream of a fault position. Selectivity must be verified at all levels of the distribution, typically: At the main
