Main Earthing conductor size.

TNS ?

No, TNC-S. I already have but this is the first time I've seen anything less than 16mm used before. It just threw me off. So am I safe in assuming the inspector will be happy with 10mm?

Are you being assessed on this job? If so, it's important to be able to say why you think the install is ok as is ...

Yes I am. It's my first one for NICEIC. I understand why we have minimum CSA's for Earths but having never seen one this small on a domestic job just threw me off a bit.

Its NOT unusual for properties to have a small link to the water pipe, or worse, no earth at all.....
