So it works out cheaper to buy RCBOs as a CU package and just put the CUs to one side.
Yes if it’s on offer

Fitted many hundreds, and never had any serious hassle..And serious hassle when it starts tripping ...

Well just for the record, I’m all for RCBOs too..
Next time you get chance do a few tests upstream and observe the earth leakage.
Think you will be surprised by how high this can be, especially on large installations.
So do some thinking before you next visit and sketch out a plan of attack. You might want to buy some RCBOs say 6A, 20A and 32A to leave some final circuits protected by them rather than the RCDs - in case the fault happens to be intermittent and not easily stimulated - then at your next visit you will have some new information from how they and the RCDs react.
No , I’m going to ramp test the rcd against each circuit building up to full load, then see what the earth leakage is. I’m then going to see if I can re balance the splits and if not retro fit RcboS, I suggested these to start with but as usual they didn’t want the cost.Eliminating appliances for accumulation is no good really..
You remove 1 non faulty appliance and hey presto all is ok. Replacement gets bought, plugged in and RCD trips again.

I think it's Lewden and they are cheap in Englandshire.What’s this cheapo RCBO board?
