50amp surge protector ?

Earlier posts on Hughes Bulldog make it sound like it might be worth a look.

The go-to for years were the Progressive Industries units. After a recent buy-out, though, complaints have gone way up. Issues with weatherproofing seems to be the biggest complaint followed by warranty problems. Still not a bad unit, but you need to know what you're getting in to. There are other options out there. Now, PI's hardwired units don't seem to have the same complaints since, obviously, they aren't exposed to weather, but the warranty issues still remain. There's one unit, can't remember which one, that is rebuildable after an event that takes it out.
