We are combining two cottages, one of them really small, into one house. The little cottage has an old distribution board and meter plus company fuse. There are only four circuits - two small power rings and two lighting, with a maximum estimated load of 12.5 kW (we are putting the "laundry" in this part of the property.
I have already bought a Wylex 17th Edition ten-way insulated CU for the larger cottage (potentially eight circuits) and propose taking a heavy-duty link from this unit to a mini unit (say five-way) in what was the little cottage, thereby doing away - courtesy of NEDL - with the second meter, mains input and company fuse, and ill-assorted bits and bobs from 50 years ago.
Could I put a 50A MCB in the main CU and take a feed to the mini unit via a 10mm T&E (about 22m distance)? Would that be legal and safe (using an accredited sparks, naturally, to supervise and sign off the work). Or would the answer be to fit a separate 63A RCD to the large unit and feed from that?
Any advice and suggestions very gratefully received.
Many thanks
