    RCD

    Residual current device

    This one is operated at the time of fault occured in
    earth leakage,then this is have triping mechnism also

    Types of RCD

    RCCB-Residual current ckt breaker
    RCBO-Residual current ckt breaker
    and over Current protection

    RCCB -commonly we use for multiple ckt protection
    but we need to add some MCB`S for over current
    protection

    RCBO-here we use rcbo in single ckt ptotection in
    earth lekage
