Hi,
I undertsand this to be a TN-S system as the earthing arrangement comes along the SWA metal sheath surround but the Ze i got is 0.19 which falls out side the regs of 0.8.

I have also read on here that if the earth is then connected to an earthing block as shown on picture, it then becomes a TN-C-S! which doesnt make sense as the earth is outside the sheath not inside on the neutral!
Which is it?
