The RCD has only limited breaking capacity and it is not a replacement for overcurrent protection devices such as the MCB. The residual current breaker with overcurrent (RCBO) is now available; this is an rcd with an overcurrent tripping mechanism and enhanced contacts to cope with interruption...
RCBOs An RCBO Is essentially an MCB and RCD in one device however, it does not typically get used across an entire board to substitute MCBs as an RCD is not always necessary on some of the other circuits. Understanding why a circuit can trip out and when you can reset it yourself Too ...
