Typically you will have both a single large TVSS on the utility entrance to block all the big hits, then have TVSS in the main panelboards.
No, I mean should the TVSS surge supressor be a stand alone unit or a TVSS that actually goes in the panelboard?
Oh, I see. It doesn't matter. Personally I like stand alone TVSS that are not in the panel, because they are easier to get to and replace if needed. Also, for our really critical circuits, we like to upgrade and use higher-end surge suppressors, which usually means we have to get external TVSS modules.
