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

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?Not always.

It wasn't configured for any non RCD positions.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?

...and conversely, if it did not have three neutral bars, what made it 'high integrity'?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?
... 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?It wasn't configured for any non RCD positions.
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!...and conversely, if it did not have three neutral bars, what made it 'high integrity'?
