Thanks for the reply. I now realize that Bussman doesnt even make a 200A version, but Tocas does offer a 200A breaker (which you mentioned) which is the only option that I know of. Unfortunately the Tocas 200A breaker is not marked or approved with any certifications. MIdnite does offer a 250A and 175A breaker for about $90, but not a 200A, which is weird. Im thinking going with the Midnite 175A and my 200A fuse, rather than the Tocas 200A breaker, 200A fuse, and disconnect switch. This will only be about $30 more but will be easier and a cleaner setup. And I believe the midnite breaker is also available with a disconnect relay that could link up to an inverter or BMS.
