Why do some people say they are non compliant when they are?
That's the nub of it without going into another long discussion on the subject.Because strictly speaking they are not.
I don’t remember the exact wording but it relates to minimising disruption, nuisance tripping of other circuits, how can this be achieved with a single RCD protecting multiple circuits? It’s in the regs, I’m sure one of my learned colleagues will be along shortly with reg reference.
Regulation 531.3.2 was introduced into the first 18th Ed which permits subdivision of circuits and an individual RCD however you are asked to consider Section 314.
So are they compliant, yes according to Regulation 531.3.2 providing a considered approach is employed.
because if you read the regs they are not. selectivity for a start. and then division of installations.Why do some people say they are non compliant when they are?

I did once help out, (whilst on holiday, I add) with some fault finding in France. There was only one RCD, if I recall correctly.f you've ever done fault investigations where an installation is experiencing, random intermittent tripping on a dual RCD board..
The question was about regs not if they are any good
Yes we have all come across RCDs tripping and people losing half there house a pain but not rocket science to repair.
If the customer doesn’t want to pay the extra £200 for RCBOs it’s on them
I don’t use them as a rule but preference is not a regulation

You can get them now double pole rcbo single module fuse boxI did once help out, (whilst on holiday, I add) with some fault finding in France. There was only one RCD, if I recall correctly.
The MCBs, same appearance and size as ours, were all double pole. What a huge advantage for fault tracing!
Why are UK ones only single pole?
Really it was a figure and how is it so out of date when there is no information how many ways for exampleExtra £200 ??
Your pricing is well out of date
You are looking at around £10 extra per circuit. Given that many electricians are charging £800+ for a board change, it's not a lot more.The question was about regs not if they are any good

but the reg youve provided limits their use and goes against your argument of they comply...I don’t use them as a rule but preference is not a regulation
Regulation 531.3.2
again, which reg? so far the only one youve provided suggests otherwise...Your cheap if you charge £10 extra per circuit
Not seen RCBOs under £10
But it does comply
