Perform lighting inspection and Megohmmeter test for lightning strike. Completed retrofit of fluorescent fixtures with bad ballast. Due to the circuits thar failed the Meg test. It is recommended that a re device be done. This will tell us if it’s just the devices that were affected or if the wiring insulation has been compromised. Service wire also had to be replaced being that the strike affected the panel and went to the main where the ac is connected. Whole home surge protection has been installed to help prevent this type of issue.
