How to wire up a consumer unit

Arran Cameron

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?

    You will have trouble finding anything even semi-official for free on-line.  The IET will quite happily sell you everything you need to know https://electrical.theiet.org/




    I have noticed how engineers who aren't members of the IET often have the latest and greatest consumer units filled with all sorts of cool gadgets. Engineers who are members of the IET often have to make a choice between buying a kWh meter or paying the electricity bill.
