unless you have a plastic water supply pipe :)
We don't... old house.. but I still have 50m of reltively small cross section cable from the house to the shop.
There will be, I would think, significant resistance in the earth wire.
The cable armour is not connected to earth AFAIK (was installed before I moved here) It's 3 core, and the earth wire is my shop earth
