Not all RCBO's will test in isolation, at source...

Read his other posts and you'll see why.
Seriously - do read them, or at least a significant number of them - a worrying picture emerges.....
Not sure where you are going with this? A 30mA RCD is a 30mA RCD which I don't see why you can't test in isolation at source - isolation meaning that the outgoing wires to the circuit are disconnected. If it fails to trip then it is a fail and requires replaced.
I presume he is reffering to the MEM RCBO pods (which are availible either already combined with a MCB or seperate for field fitting), these monitor the live by running the outgoing live core through the current transformer. Therefore if you test by probing the output terminal they don't trip.

Thank you very much plugwash,
I don't condone the use of MEM equipment, but do have to work with it from time to time

Test downstream from the RCBO, after the CT.
Cack idea IMO.

Could you explain why you've fitted anything into a bathroom without a CPC?
Does your insurance policy cover you to carry out illegal and dangerous work that fails to comply with The Building Regulations and conflicts with the guidance given in BS 7671?
ANYTHING without a cpc?
SELV transformer? Class 2 device?
