This picture was taken in Las Vegas last month, and shows were the conduits are corroded at the point of contact with the earth.
They were wrapped with tape, but it looked like there was not enough provided.
This is a common situation around the country, and could use a technical reply from someone who may know the reasons why this happens?
I will also search for that information in the UL Directory "White Book" and add comments later.
