According to the National Weather Service, lightning causes over $1 billion in property damages every year in the United States. Installing lightning protection can help prevent these costly losses. An unprotected structure has a 1 in 4 chance of being struck by lightning over 30 years. Properly grounded buildings have a greater than 99% …
If the resistance to earth of a lightning protective system exceeds 10 Ω, the value should be reduced except for structures on rock as described in 18.5. If the resistance is less than 10 Ω, but significantly higher than the previous reading, the cause should be investigated and any necessary remedial action taken.
