Hi forum people. Im really not sure what type of earthing system my house has.
Im know its not TT

BUT NOT SURE advice needed. Earth come out fo the DNO's fuse to the right of it.

I Realize you can't see the image.
So older property, main fuse, main supply in and a clamp just under main fuse supplies earthing.
So actually probably TNS am i correct?

if its clamped on the sheath then its almost certain to be TNS

Andy HI

Yes its clamped on the sheath about 4mm under the main fuse.
So TNS then?
