How to wire up a consumer unit

A semi-detached house has a prehistoric fuse box with rewirable ceramic fuses. It will shortly be replaced with a modern consumer unit. The existing circuits are:



 



1. Lights



2. Upstairs sockets



3. Downstairs sockets



4. Kitchen sockets



5. Cooker



6. Shower



 



The following circuits will be added to the consumer unit:



 



7. Central heating



8. Burglar alarm and CCTV



9. Outside lights



 



I have been informed that the best choice is a split load consumer unit with two RCDs and space for RCBOs. My intention is that circuit 8 has its own RCBO but what is the optimal way to allocate circuits to RCD A and RCD B? Also, should any other circuits have their own RCBO?

     The Institution is supposed to be a promoter of engineering education and a role model for professional ethics in UK engineering, not a money-grabbing outfit focussed on its own profit above all things.




    There are times when I think it is yet another swanky London club considering the prices it charges for membership and technical publications.

    Open publishing is thriving, while the proprietary publishing model is widely condemned in the sciences and many other disciplines. In contrast to these advances in knowledge dissemination, putting engineering standards behind a paywall is taking UK engineering back to the medieval days of shady masonic guilds protecting their trade secrets for their own profit. It's astoundingly bad on numerous grounds, particularly in respect of discouraging education, limiting public knowledge of legal requirements, impacting on public safety, and in making "information only for the rich".




    This reminds me of how Asperger Syndrome was only known about in Britain and other English speaking countries during the 1980s by a tiny elite group of psychiatrists. Lorna Wing published a paper titled Asperger's syndrome: a clinical account in the February 1981 edition of Psychological Medicine, which was the first reasonably in-depth article about Asperger syndrome written in English.

    She made no efforts to raise awareness of Asperger syndrome in the wider medical community or amongst teachers and educational professionals by writing any books or articles for more mainstream publications. For example, if she had published an article about Asperger syndrome in the Times Educational Supplement then she would have reached out to a wide audience of people who deal with children on a daily basis. For 10 years the only significant English language article about Asperger Syndrome remained hidden away in an obscure academic journal. The Maudsley Hospital where she worked was the only place in Britain that could diagnose a person with Asperger Syndrome until the 1990s. When Lorna Wing died in 2014 obituaries published in newspapers made references to her groundbreaking paper but I doubt if any journalists knew about the existence of the paper during the 1980s.


    Uta Frith translated Hans Asperger's papers from German into English during the 1980s and she published the book Autism and Asperger Syndrome in 1991. This book was remarkable because it specifically used the term Asperger Syndrome in its title as opposed to just autism, and it was written in a style that was designed to be easily understood by parents and teachers who had never studied psychiatry - as opposed to being a highly technical publication that only professional psychiatrists are able to properly comprehend. The result is that Uta Frith, rather than Lorna Wing, is usually regarded as the person who made Asperger Syndrome public knowledge in Britain and English speaking countries.


    Is history repeating itself at the IET?



     




    IMO I would use DP RCBOs if cost is no problem plus I would use a M/C DB larger than the standard domestic sized.
