NEC generally just says that physical separation is a potential means of dealing with the fire hazard, but does not dictate the distance of separation required. Apparently, that detail is to be provided by the insurer. Factory Mutual is one rather conservative insurer -- but at least they are also prolific publishers. FM requirements for physical separation with various transformer fills can be found at: ht
Hope that helps....
