Running a 25mm 3 core SWA submain to a new CU. So I terminate the the SWA in a box adjacent to the CU and route the L & N to the main switch in the CU.
However the earth bar in the CU only takes up to a max of 16mm cable. Can I fit an earth terminal block outside the CU and then take a 16mm from there into the CU?. I would also have to do this at the meter end since the switchfuse can only take 16mm as well - but here I plan to use 25mm to MET is this ok?
thanks
