I don't see a problem, at all..Yes, right next to it
My boys don't have an issue with this at all.If this is an accepted method there would be no reason why you couldnt RCD any circuit without having to split the tails into a seperate CB/RCD combo.e.g. say you had to RCD the lighting circuit & you couldnt get an RCBO for the CU or move it onto the RCD side then you could run a piece of 1.5 from the existing CB in the CU, through an RCD next to the CU & then off to the lights.
Ive seen this mentioned on here before but nothing was really said about it (I dont think)
Trust me, he is responding.I don't see a problem, at all..But hang on, Special Location, is about to reply.

Putting a shower into a refurbed office with a Merlin Gerin DB. The RCBO's for this board are

That is some quick thinking & typing Applaud SmileyThe order of connection is irrelevant..they both perform independent electrical functions..
and operate quite independently of each other!
e.g. consider a traditional split load board..
one half has RCD then through MCB's to final circuit & load.
whereas an older Non-RCD board may have had additional RCDs built in for specific alterations that have been carried out..
i.e. whirlpool path RCD off U/S sockets?
Outside socket.. RCD FCU off ring
Or the average home owner with their plug-in RCD adaptor for the lawn mower.
All these have RCD after the circuit breaker.
so as long as you document where it is and all items are clearly labelled and are suitable current ratings for the required load...
then cant see why not?
There is no reason why the supply path to a particular item of equipment cant go through several RCD's / Circuit breakers...
just need to ensure any relevant discrimination is built in to avoid incorrect protective device operating at the wrong time...
same principal as ye ode 'TT' set-up 100ma RCD feeds some MCB's & then also 30ma RCD & further MCB's
as per the old Fig 3a pg 21 OLD O-S-G...
(OBVIOUSLY THIS ARRANGEMENT RATHER SUPERSEDED BY 17TH ED!)
The OP is suggesting to feed from a 40A MCB, off the Main CU, here Dan.so if using this method (which i thought was frowned upon,but hey ,you live you learn)you dont need a CB in rcd enclosure? its wired direct to the bottom of the RCD without the busbar? this will save me loads of hassle.
erm not sure what you mean hear m8?sorry didnt know you could wire the circuit live direct into an rcd.
Neutral Bar??? ?:|ill try explain what im on about.run a length of 1.5 from original 6 amp CB to incomer side of standalone RCD then run original 1.5 to new RCD ,neutral to neutral bar ,live to load side instead of busbar ,earth to earth bar.
