Hello,
i am currently trying to find everything on Lightning protection for 1 & 2 story buildings. I do not own a copy of the NFPA. Please could someone advise on where to find out such infomation online.
With thaks in advance.
Here is a link to NFPA 780.
Scroll to the bottom and you can view the 2004 or 2008 versions for free. No the most user-friendly, but can't beat the cost.
