NEMA 3R Walk-in Enclosures; Buildings or just Enclosures?
(OP)
Has anyone run into a situation where a local construction official wants a pre-manufactured NEMA 3R enclosure treated as a building/structure? We believe it is just an enclosure and not a building and are looking for good ideas to help make the case.

Then again, the NEC definitions of buildings and structures could be construed to mean a flagpole is a building. It is a structure because it was "built or constructed" and it is a building because it is a "structure that stands alone". How do you appeal to common sense?

If the enclosure is UL-labeled as a piece of electrical equipment, that might help. Obviously, you should inform them that generally no one is ever inside the enclosure except for specific maintenance activities.
Good luck...
