RCBO or not?

[alexander jackson]

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.
Many thanks
AJ.

Most instructions, including the one linked to earlier, ask for rcd protection… so that’s the answer in this particular instance.

Whether regs demand it or not, we must take manufacturers instructions into considoration.
