Which type of residual current device RCD is used in a distribution box
Fixed RCDs are typically installed in the fuse box or distribution board and provide continuous protection for the entire electrical circuit. This is the perfect type of RCD installation for most business premises. 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. Residual Current Devices (RCDs) are safety switching devices. Any tripping current dependent on the resistance of the earth path. In addition to the detection. An RCD, which stands for Residual Current Device, is also known as a Residual Current Breaker (RCB) or Residual Current Circuit Breaker (RCCB).
