There are already 3 neutral bars in there... you'll not require the additional bar if you don't require circuits without RCD.With extra bar ordered

Indeed. Things sold as "high integrity" CUs (goodness knows where that term came from!) always do -one for each of two RCDs and one for the non-RCD circuits.

Not always. I fitted one last year for an EICR but I did enough that I truly can't remember which property or what make it was. Of course it had to be the one which required a non RCD position.

I can't see how they could sell one configured for two RCDs and some non-RCD circuits which didn't have three neutral bars, could they?
Kind Regards, John
It wasn't configured for any non RCD positions.
...and conversely, if it did not have three neutral bars, what made it 'high integrity'?
... in which case, it wouldn't be what they call (for whatever reason) a 'high integrity' CU - so why did you say 'not always' (in relation to 'high integrity' CUs always having 3 neutral bars) if the one you were talking about wasn't that?
Kind Regards, John
Exactly. This weird (in my opinion) term 'high integrity' seems to mean (and only mean) that it has provision for 2 RCDs and some non-RCD circuits (and hence 3 neutral bars) - so, as you imply, if it doesn't have those features then it's not what 'they' call a 'high integrity' CU!
