Hi Guys, I posted a few weeks ago about trying to find a RCBO for an oldish proteus cu for my downstairs sockets. I am struggling to get one and the guy at CEF said I would be better fitting a seperate RCD protected cu just to feed the downstairs sockets. I have read a lot of posts about using henley blocks to split the meter tails but I dont really want to start messing about getting my supplier in etc. Am I right in saying that i could feed a new cu from the existing mcb on the original cu. If so, could someone explain what I will need in terms of material. Do I use my existing 32a mcb and feed to a new 30a RCD cu with 2.5 and use another 32a mcb in the new cu to reconnect the circuit. I dont intend doing this myself but I need to buy the material and the guy at CEF is a bit condescending so a bit of useful background knowledge would help. Also as its not a new circuit and using the same sized mcb would it come under minor work?
