The arrangement is just like mine - it's likely to be a TNCS or PME system, where the main earth point emerges off the right hand side of the incoming service fuse block itself.
Could you please, for the love of god press your caps lock key!!!
Your description doesn't actually explain where the earth cable goes. Does it go inside the cutout or does it go to the sheath of the supply cable?

Almost.
TN-S does not neccessarily use the SHEATH of a cable (S is NOT sheath). The SEPERATE path could be a seperate earth cable (common on larger supplies), a core IN a cable (such as a split concentric cable), or indeed the sheath or armour.......when I say armour, it most likely to actually be a wave form concentic covering.
OP: Any chance of a photo so we can identify your supply type much easier for you?
Congrats on 1000 posts Davy!!

Lec,
I know, I was just trying to keep it nice and simple for the op. Could also be an overhead supply!! If we were to go into all the different variances of the different supply types my reply would have ended up being like war & peace

Overhead supply would be as I termed 'seperate cable' wether above or below ground
And they are *pretty* much extinct!Lec,
There's nothing pretty about overheads, and we do have a few up here! (right outside my window)

I was talking all TN-S.......
No, I have plenty of overheads here, but they are PME or TN-C-S.....not TN-S
I know of an overhead TN-S round our way. Will get a pic next time I'm up there
