Main Earthing Cable

[Mark.W]

Hello Chaps

I'm upgrading a Main Earthing cable from the Electricity meter to the MET from a 10mm to a 16mm. What are the necessary steps that I need to take? I haven't done this before? Not sure whether I need to isolate the supply or if I can just unscrew the old 10mm and replace with the 16mm.


Thanks
Mark

I agree I've never changed the main earth to the incomer so I'll give the local DNO a call tomorrow! I have done bonding before but never worked upstream from the CU, especially not on TNS! but thanks for the good advice as always.
