main earthing conductor

[michael_brooke]

Hi all
I come across main earthing conductor coming out of fuse carrier which is 16mm earthing into henley block then 10mm out of henley block to main earth terminal in cu, ive been writing down 10mm as main earthing on test paper, would like to know what every1 else puts in this situation,.

i'd use the worst case, 10mm. and code it as a C3.

think he means PME tail from cut-out, 16mm into henley, then a 10mm to CU.

That makes sense, I'd got all sorts of weird ideas about it.

If that is the case it makes you wonder what went through the mind of the person that did it that way!

Perhaps it's a recent upgrade to the supply, and the DNO installed the 16mm².
Or is that just silly?
