TN-S mains supply

Hi guys, I have a TN-S mains supply with a 100 amp fuse. I was wondering if anyone could tell me what size diameter earth cable and tails should be fitted. cheers Damian

These are minimum sizes for a 100a service fuse

I concur with PaulH53, for 100A main service fuse all tails MUST be 25mm and the Earth 16mm. Any smaller and the REC will likely refuse to connect.
