Hey all, just been doing some testing and in a block of flats all the CU's are fed from the hydro splitter box in the picture. in each flat, and this landlords cupboard, where there is a bs1361 100a fuse there is a label saying "solid link - Do not remove" how would you note this on the test sheet where it asks for main protective device(or similar, haven't got them infront of me). i presume they are fused inside the splitter but there no info about what's inside. Thanks for any help.http://Upload the image directly to the thread.com/HUSABdz.jpg
