The National Fire Protection Association (NFPA) updated their code within the past couple of months. They update their code every three years which gives us the NFPA 780 2017 Edition hot off the press. There have been a few significant changes for commercial lightning protection systems. One that is particularly exciting includes a lightning protection system that can be a stand alone with only one downlead within certain parameters. There can only be one air terminal needing to be grounded and it can’t be over a certain length. This is particularly beneficial in situations where poles (i.e. a flagpole that can’t carry a charge on its own) need to be protected because two cables running down gets bulky and excessive.
