WebRCDs. RCD is a generic term for devices that detect residual currents and disconnect the circuit if the residual currents exceeds a predetermined value. The following RCD formats are defined in the IET Wiring Regulations (BS 7671): RCCB - Residual current (used with an MCB) Fixed characteristics - EN 61008; RCBO - Residual WebDifference between MCB and RCBO. MCBs can provide protection against overcurrent and short circuits only. RCBOs can provide protection against overcurrent, short circuit and earth leakage currents. MCBs are selected based on the load, the maximum short-circuit current it can interrupt safely and trip curve. RCBOs are the combination of MCB and ...
