RCBO

[whyme!]

Looking at a new 16 way consumer unit for my house. I was just wondering are RCBO a newer alternative to using mcb in unit? If they act as an mcb and rcd does that mean if all circuits are on an RCBO that rcd is not needed? Or are they really only for older units that have non RCD protected circuits
Was looking at a MK K7666SMET Amendment 3 Metal Consumer Unit. Are these ok?

RCBOs are the latest devices.

As you say, an MCB and RCD combined, one for each circuit so faults do not disconnect other circuits.

So no RCCB (what you called RCD) is not needed.

 

[whyme!]

Ok thank you. If you have circuits protected with RCD (RCCB) then, the use of RCBOs is more a personal choice

Usually comes down to price - obviously sixteen cost a lot more than two.

very true, think i can handle asking the wife to get up and move a rcd breaker if her curling tongs switch my tv off

Im sure Mk recently had issues with there rcbos and people here say there not what they used to be.
hagar seem to be worth costing up as an alternative

 

[EFLImpudence]

Yes, Hager best.

 

[whyme!]

something like VM120K

Thats a 20 way Main switch board, only good for an all RCBO install.
Big with spare ways is good if you have the wall space, though if you do need 18 rcbos there not cheap.
I dont do domestic stuff, a few of the regulars do, i quess they will get back to you soon.
most good deals nowadays are on 2 rcd boards which come loaded with various mcbs.
rarely any deals if you opt all Rcbos, as you will need the main switch type enclosure like you showed and all rcbos.
Also a lot of good deals on BG 2 rcd boards at the moment, they look ok, as for quality, someone may advise shortly

 

[whyme!]

I like room to expand, rather have blanks than worry i don't have enough space for new circuits. Looking at rcbos could cost an arm and leg. Maybe just a high integrity system and put smoke alarms, fridge etc on rcbos others on rcds

Oh yeah
16-MODULE will keep looking then https://www.electrical2go.co.uk/mk-...gle_shopping&gclid=CMe0gZD_o88CFcsy0wodiJ4Efg

Maybe the Hager VM120K
is way to go, decide for myself what to have, mcd/rcd or rcbo just need to find a supplier

on the same website you linked to! Reasonably priced hager RCBOs on that website too.

Be warned though, for reasons known only to hager, their RCBOs do not have the grey window that the RCBOs have. Obviously you'll never see it with the lid shut, but it annoys the hell out of me.

Yes i think i will opt for the VML120 and go RCBO route. Will be a gradual change as renovating a house, extending so can be done gradually while the old walls are stripped back to brick, ceilings down. Make life easy for the work required. Plenty of circuits can go in it too. How the house never burnt to the ground with current wiring i'll never know.Even a few bakelite sockets i might frame to remember how it was

Bought the Hager VML120 Design 10, will cost slightly more for protecting circuits than having RCCB and MCB but only by a few hundred££
