if you have an existing installation where the earth bar in C.U is being used as the MET( main bonds/main earth) and you now split the tails via henly/switchfuse to install a submain. is there anything stopping you splitting the main earth in a seperate MET then feeding the existing C.U. and switchfuse from the seperate MET making sure that CPC is sized correctly between MET and the C.U earth bar. i only ask as sometimes the mainbonds cannot be easily removed to connect to a single MET.
