Whole house surge protector

I have a 400 amp service. I thinks it's really just 2, 200 amp services run to 2 separate panels. There are 2 separate shut offs outside, but just 1 meter. I also have a 100 amp generator panel fed from the second 200 amp panel. Can I use just one whole house surge protector or do I need one for each 200 amp panel. There is plenty of room in the 200 amp panels, but the 100 amp generator panel is full.

Thanks again for the help.

if rated for the 400 amp then you can use one surge protector. Panasonic makes a good one for this job.

If you are in FL you need pretty hefty protection.

If you have 2 panels you would need one for each panel.
