In a domestic set up ie average (if there is one) house is there any reason you wouldn't use a RCBO but a MCB and a RCD?
I can't think one

Cost. Also the RCCB will switch the neutral pole whereas the RCBO may well be single pole and leave a neutral/earth fault in situ. Not good if there is an upstream RCD.
Did you mean 'not good if there is not an upstream RCD ' ?
If there is an upstream RCD then that will clear the fault and the SP RCBO will not be so much of a problem.
But the fault will cause potentially a total loss of supply.

RCBOs single and not double pole (majority)
RCBOs expensive compaired to a split dual RCD board fully loaded
RCBOs take too much room up in average domestic boards, not curves though
RCBOs have horrible white fly leads which look like a ball of wall in the boards and make the boards harder to look neat
RCBOs have horrible long neutral leads which look like a ball of wall in the boards and make the boards harder to look neat.
RCBOs are better for individual circuits rather than an RCD covering 5 breakers in a split due to nusience tripping
How many more examples would you like?

A curve board with an s type RCD up front and individual rcbos would be a good choice on a TT system, that said it would cost 150 notes rather than 50 a split would costAre you a fan of RCBO's? lol

A cheap enclosure with a lot of space above the dim rail unlike most domestic boards, that said when the regs change they may disappear from the market fella.I've not heard the term "curve board" before.
Better than it causing a fire of there wasn't the upfront protection
Can you specify the type of RCBO with regards to the number of poles it is switching as that will affect the answer?
Hi,
Yes, cost is a problem. I have just bought for my own place a Schneider board with DP RCBO's from a company in the UK ( no advertising here, but most will know who I mean ). No flying leads Neutral/ Earth, plenty of wiring space. Not used one before, so this is my first use of the product. RCBO's are £13.00 ea so not expensive when compared to other makes of SP RCBO's. It all depends what the customer is willing to pay, all you can do is give them options and let them decide.
Regards.
Yup good shout, add it to the list for the OP :biggrin:RCBO's a far better way to go with an older installation and/or a poorly extended property!
see my redRCBOs single and not double pole (majority)
Ok I'll give you that one as you say majority, but the sbs rcbo's are DP as highlighte in other threads.

£15 (or there abouts inc vat) for an rcbo isnt budget breaking as opposed to other branded single pole units.

You've not seen or used the sbs rcbo's then.
RCBOs have horrible white fly leads which look like a ball of wall in the boards and make the boards harder to look neat
Not all.............the ones I use don't have the white functional earth lead
RCBOs have horrible long neutral leads which look like a ball of wall in the boards and make the boards harder to look neat.
As above, why because they are DP but with the added advantage of being the same size as an MCB.
RCBOs are better for individual circuits rather than an RCD covering 5 breakers in a split due to nusience tripping
Correct apart from Nuisance and not nusience

No if it's SBS he is up north &only sells to trade.The customer is me and would the company you cannot say have an outlet in Saltash?
Ok so under fault conditions the rcbo in question trips, now does the line & neutral isolate?SBS RCBOs are not DP they are SPSN
what yu talking bout man, your replies in red are very attractive but so what lolsee my red
Ok so under fault conditions the rcbo in question trips, now does the line & neutral isolate?
I would take that as DP isolation...............but maybe I'm wrong?
And I'm not being pedantic, If I'm wrong I'd like to know.

Isn't he the guy that misused his NAPIT contacts list to mail shot electricians? The bloke was in Cheshire, or similar?Think you'll find the company is called SBS Trade Sales...
