rbalex said:It is quite possible that one side of a physically created boundary is Class I, Division 1 and, assuming the boundary is unpierced, the location on the other side the boundary is unclassified. If this is the case, then the panel may be any type otherwise appropriate for the location.
If the panel feeds loads inside the building, then appropriate boundary seals may be needed, but it would not generally affect the panel type.
