Current operated ELCB

[Abuelo]

What is the most sensitive current-operated ELCB that I can buy for fitting in a domestic single-phase system? Is it less than 30mA, and if so where from?

google 10mA and 6mA RCDs.

I've seen 5mA RCBO's use in marine applications but I can't remember what make they were. I'm not saying this is the lowest you'll find, it's just the lowest I've seen.

I think that they can go as low as 2mA, but for domestic use, 10mA for socket outlets is normally the lowest used.

Thanks, but where in the UK can I obtain by mail-order 3 or 5 and 10 mA current-operated ELCBs as single items.
