Dual busbar under the RCBO, and DP RCBO with the same form factor as a normal MCB, But you won't ever see these in the sheds.
January 23, 20179 yr Just now, PeterW said: Explain please.... And most of these don't use a bus bar and the Neutral / Live are next to each other on the feed so how does that work..?? OK, bring in your twin and earth cable to the enclosure. Line & neutral goes to L&N of the RCBO (either top or bottom) and the cpc (circuit protective conductor) aka "earth" wire goes to the earth bar top left. That's it. Ref the bus bar, it's two separate, "staggered", insulated bus bars: Obviously if you bring your circuits in to the bottom of the assembly the bus bars would go on top. Can supply details of the supplier of these if you discuss with your sparks and he contacts them.
January 23, 20179 yr OK so the bus bar pitch is the same as normal..? How does that work with the neutral that normally is to one side of the line ...? I can see how if they are "stacked" then the line can hit the isolator correctly - do they come with bus bars to match..? And whats a CPCS..??? As its not a Construction Plant Competence Scheme....

Supplier may be of use although I'm doing the buying as he's on install labour only And I now get the reference to CPC's, it was the CPCS bit that threw me ...!

January 23, 20179 yr Yep to start with ..! Interesting way of doing it too - shows that things move on and it makes a very neat install.

Yep, you simply wouldn't use SP RCBOs, and these are a comparable price, Assuming, (and I know I shouldn't) that OnOff and myself both obtain these direct from the same source, they are not afaiaa sold to the public, but only to Electricians who have evidenced it to the importer.
January 24, 20179 yr Author This conversation illustrates why I employ electricians and build fences.

Is this the guy who's a sponsor on the electricians' forum? At one point I looked into getting our unit from him but my electrician was wary about where the RCBOs were sourced, then other things got in the way so I ended up with a large Hager box (three phase with a conversion I think) with SP RCBOs.

Yep, They come from the same source many brand name RCBO s and MCBs come from, and are widely used worldwide where mostly only DP RCBOs are used, Yet another area where we are in the dark ages and still permitting SP RCBOs as acceptable under most circumstances. As I'm sure you know, most of these things are simply rebranded generic clones.

Yes, my electrician and I looked into it far enough to agree that was the case. I can't remember exactly why we didn't go with it in the end. I think he just felt more comfortable with branded, which I can understand given what's at stake. Given the size of the house and the number of circuits needed (ASHP, PV, home automation, stupid number of kitchen appliances, etc) we ended up with a Hager three-phase board with conversion pack(?)
January 24, 20179 yr Yes, hence the move away from a domestic CU! Please don't tell me any of this is lethal!

Anyway don't panic there are many many things that are lethal, my younger brother nearly killed me with a chicken Kiev many years ago (true story).
January 24, 20179 yr I've seen Jack's board first hand, when his electrician was there wiring it up, and can vouch for it being big. Very big!. I've seen smaller boards in small factories.................
January 24, 20179 yr But there are only 22 circuits, it would have been easy to get that down to 20 and use the same large domestic board as I have. e.g do you really need a dedicated circuit for a shaver socket? And I am going to regret asking this as I am sure the answer is obvious, but what's the yellow "loxone" label on half the circuits?
