Hi
I am a newly qualified 'Domestic Installer' and cold do with some more professional guidance. I am installing a new consumer unit no more than 20m from the mains. This will be from my main board in a dwelling to a shop below. Fed from this unit will be 2 lighting circuits and a socket ring.
What is the best method of connection to the main board?
I am considering
40a DP RCD unit
10mm cable fed from a 45a MCB to the new consumer unit. (Is this big enough?)
20a MCB for sockets (Heaviest load will include a fan heater at about 2.5Kw plus minimal appliances, clock, radio etc)
6a MCB for main shop lights
6a MCB for illuminated shop sign
Are there any other considerations you acn think of or anything I haven't considered?
Thanks guys
