The DNO earthing on a TN-S supply to the MET block is no more than 6mm. On the customers side the Main earthing from CU to MET is in 16mm and the bonding to the Gas and Water is in 10mm.
The Ze readings are low at 0.13, is there a requirement to get the earthing from the MET to the supply head upgraded to 16mm even though the Ze reading are within spec.
Thanks
