hmmm i'm under the impression its not that clear cut Apache

the reason for this Q

 
Table 54.8 would disagree with that and support Patch. Neutral is 35mm or less, then 10mm. Check out BRB pg 134.

 
How so?

Tails: 25mm

Earth: 16mm

Main bonds: 10mm

Main bonds TNCS: 10mm

 
quote "buried earthing conductors must be atleast: 16mm copper if not protected against mechanical damage but protected against corrosion

"

?
