Any seen a RCBO like this before?

[Raptor0014]

Whilst looking for something else I noticed this on CEF and wondered if they had marketed it wrong and it was infact a RCCB and not a RCBO.

63A Double Pole 2 Module B Curve 10kA 30mA Type A Mini RCBO

Compact modular design

But looking at the data sheet it appears it is indeed a RCBO. Just curious as it doesn’t appear to have a neutral fly lead. So can only assume it is meant for the incoming supply rather than an individual circuit.

Has anyone used one before?

I don't think I've ever fitted one, but you sometimes find lower rating ones in their own enclosure.
This was a B32 30ma type AC.

I think this was someone's attempt of adding a compliant shower circuit to a bathroom that didn't have bonding, running off a Wylex rewireable board. It got removed when the board was changed.

Yes I have seen and fitted them before, double pole MCB & RCD all in one, I use them a lot on marinas and caravan sites. Very handy units and until RCBO'S became double pole were one of the few options for double pole isolation without having an MCB and RCD taking up 3 modules!

Isn't this the sort of RCBO that would be common in ROI and many parts of continental Europe?

I believe it is.

It also shows the thermal/magnetic trips in both paths which is required in some places without the UK's historical insistence that neutral is really neutral and close to true Earth. Most DP RCBOs you see now in the UK (compact Wylex, Fusebox, etc) are neutral-switching, but they do not sense overload on the N path (though a fault only on N would be tripped by the RCD side of things).

Quite often see them in things like caravan hookup points.

Yes we use a lot of double pole rcbos when working in the south of Ireland

Double pole switching 2 module RCBOs are very common in Ireland. (Specifically in the south - not in the north where BS 7671 applies.) I actually prefer them to single module devices.

Yes.

Hi, I'm just about to fit an MCG 63A type A, C curve, 2 pole RCBO (Awaiting from CEF) for a new 10mm SWA supply from my meter cabinet. The data sheet says the incoming supply can be either top or bottom. - That's okay, but it does not show which polarity for N and L, just 1,2, 3, 4 on the small picture test circuit. My question is does it matter?
