Now, I know this is a c**p question, but iv'e got my tin hat on and am braced ready. I am trying to help the son of a mate of mine who has bought a house miles away, but wants some advice. The only information on the CU i can get is that it is a 10 way wylex, with 5 ways on it's left hand side that are fed directly off the main 100A switch, and 5 ways on the right hand side that are fed off an RCCD. I don't think it is a DIN type. He wants some power in the garage, I would preferably do this via a non-RCD protected way in the CU>SWA>RCD garage CU etc. This seems quite possible given that there are 2 spare ways on the LHS bay. Thing is, what is the chance of getting an MCB that will fit this board? Any of you guys any idea what this board might be and if it's possible to get breakers for it? Apparently it has had an EICR done recently and is OK otherwise, and obviously wants the most cost effective solution. Meter tails enter through the wall straight into the CU and would be a pig to tap into to fit a separate CU to feed another board. I am really just wondering if anyone recognises this board from the rubbish description, and how likely the chance of getting spare MCB's for this and older boards generally??
