[RE-wrenches] Rapid Shutdown on Parking Garage

[James Rudolph]

Sounds like everything is a building in the 2020 code..

Here is the 2020 NEC Article 100 Definition:


   - *Building.*  A structure that stands alone or that is separated from
   adjoining structures by firewalls.


The 2020 NEC Handbook has this note after the definition:


   - A building is generally considered to be a roofed or walled structure
   that is intended for supporting or sheltering any use or occupancy.
   However, a separate structure such as a pole, or billboard sign.or water
   tower may also be considered to be a building. Definitions of the terms
   fire walls and fire doors are the responsibilities of the building codes.
   Generically, a fire wall may be defined as a wall that separates buildings
   or subdivides a building to prevent the spread of fire and that has a fire
   resistance rating and structural stability.
