Hello folks. I went to see an install the other day: A standard 60A 6 way Wylex board feeding a 4 way garage sub board at 45A and an adjacent 6 way 60A Wylex board in turn feeding (amongst other circuits) a 45A cooker circuit. All 45A circuits are fed in 6mm2 T&E. Yuk! So I'm quoting for a clean-up: I'm installing one CU to replace the two 6 ways. But what would you do with the sub main to the 4 way in the garage? It currently feeds a 30A circuit, a 20A circuit and 2 5A circuits. Would you: Feed it from the main board? Run a separate sub board from henley blocks to feed it? Or extend the tails back to the main board (on the other side of the wall)? If the first two, how would you satisfy discrimination?
