Hi
Thanks for advice. There is 6 cottages, but all have seperate western power fuses and separate meters all in one building. The appears to be no MET here. The tails and Earth travel 30m to the CU. It appears to be the same with each of the others. Although there are 6 cottages together, they are all seperate supplies and all cottages owned by different people. Therefore I am sure the MET is at the CU? I know it sounds stupid to TT a supply when it is PME but if I the main eaarth needs to be 16mm and it cant be done without digging 30m then is it not an option?
Sorry i can't envisage the set-up your describing, any chance of a photo or two of the intake building room set-up and one of the cottage supply position??
Forget any notion you may have, of degrading your earthing system, from what you have at the moment!! It not only sounds stupid, it IS stupid!! lol!!
Thought you said the supply cable to the cottage was ducted, so why would you need to excavate?? What type of conductors/cable is being used in this duct??
