Just your thoughts on this DB,it’s a Lewden type,I personally don’t like them.
Bus bar,not ideal,main switch on right,space very tight to make connections,hate the rcbo’s,screws in front of each other,making it hard to retighten .

TT?
 
@Leesparkykent its a time delayed one so "should" be ok, you can just see the S on the front of it.... The rcbos are only single pole though so there still isnt perfect discrimination and a fault remaining on the neutral will trip the whole supply... Not a great setup imo...

Yes that was exactly my point. Neutral earth fault and the RCBO will trip but the upfront RCD, time delayed or not will still trip as the RCBO's don't break the neutral.
