Hi All,
I have been asked to fit a lightning conductor to a friends house
extension
(a 'tower' like extra floor in the middle of the existing house!). How
should this be done, any special considerations etc, where do you get the
conductor from, do you have to use copper 'tape' like you see coming down
from church spires, does it connect to a normal earth rod?

Any help or advice gratefully appreciated, thanks.

As others have said, it is a job for an expert. FYI, you don't use ordinary
earthing rods, but large plates buried in the ground, and the flat copper
strip is chosen because, for transmitting lightning, surface area is more
important than cross-sectional area.
