Hi. An electrician isn't my day job but I qualified on one of those 'quickie' courses a couple of years ago, thus I am competent yet rusty on some aspects. My conundrum is that a consumer unit needs upgrading. However, the CU is situated in a low cupboard on a narrow (right hand) wall, it just fits and awkward to get to. A new (amendment) CU is obviously much larger, but would fit comfortably on the adjacent wall some 40cm away. My question please, to the venerable, is: Would it be acceptable to replace the old CU with a junction box housing, and to run the various twin & earth cables from here to the new CU nearby? Many thanks for (polite) replies!
