Note 1 to entry: one type of enclosure can be inside another type (e.g. an electrical enclosure inside a fire enclosure or a fire enclosure inside an electrical enclosure). Also, a single enclosure can provide the functions of more than one type (e.g. those of both an electrical enclosure and a fire enclosure). Enclosures may be electrical, mechanical, fire or another type of enclosures to provide protection from these hazards or from wind, weather and other hazards.
