In the home I bought here in W6, power, CATV, and telco terminate at the
same point. That's a good thing. The only attempt at an earth electrode
was about 35 ft of bare (#10?) copper (subsequently painted with the
house) that wandered to the outlet for a garden hose, which was fed by
PVC pipe. So the system had no ground.
They did slightly better in the mother-in-law garage apartment building
that now houses my shack. The same bare copper, again painted, ran from
that building's sub-panel, up into the attic, across to the other side
of the building, where it snaked along framing and a window frame, where
it finally was connected to a driven rod, the only one on the property.
There were other glaring wiring errors, including 120V outlets in a
half-kitchen/laundry room fed between phase and green. There was a
generator in a nice little doghouse, with manual transfer switches, but
the generator was missing lots of parts, so it could not possibly have
run. And a company got paid to inspect the place on my behalf (I lived
in Chicago at the time). This turkey found a list of dumb stuff, like
dimensions of exterior steps, but nary a word about electrical.
