    RCBO or not?

    Folks. I need to install a defib unit outside on a wall. Does this require an RCBO or not, just wondering as the unit has a small heater within and should it trip out for any reason other than under fault conditions (it is in a dampish environment, a harbour) it will get damp. So MCB or RCBO...

    Aaaaaaaarghhh !!!!! why ???
