No more damage after 3 decades. I paid special attention to grounding and bonding.
Note these devices are to be considered "consumables".
They degrade a little with each event, so must me monitored and replaced occasionally.
Separate from the house, I have a shed w/ HAM radio gear in it.
Antennas are static magnets.
So I implemented some of Motorola R56 "halo" ground system around the building, bonded everything to it, including the Schneider gear in the shed.
(Where I worked, we had all the 911 radio towers installed by Motorola, and the full implementation of R56 was something only a government budget could sustain.)
