MCCB with RCD bolt on, anyone know how to work these settings out? Ignore settings now but this is upfront RCD TT system so I want to top one to be 0.3 for 300mA but unsure on bottom?

Yes I know lol not set it yet, obviously it’s upfront RCD so for discrimination I’m gonna set to 300mA as various other panels have 100mA but how would I set msTop one is currently set to 500ma
Bottom one is currently set to 500ms.
put a screwdriver in the slot and turn it..Yes I know lol not set it yet, obviously it’s upfront RCD so for discrimination I’m gonna set to 300mA as various other panels have 100mA but how would I set ms
New to me didn’t know that so it’s wants to be 1 for TY?I not sure I understand the question. You do realise that the time setting on the device is marked in seconds, and so you need to convert milliseconds to seconds?
It was left on 0.1 so 100mA and was nuisance tripping, hench I’ve changed to 300mAAs a matter of interest, why does it need to be changed?
Yes that was all, couldn’t find anything online I knew how to set current just the timeIs the question, what is the appropriate time delay setting for the installation?
The minimum that doesn't cause a nuisance and at or below the reg requirement or customers spec.
