Temporary Generator Connections - Is a Parking Garage Outdoors?

[PerryLackowski]

I'm working on a new construction project, and I have a question about the new NEC 2023 code for permanent connection points for temporary generators [700.3(F)(6)]. The code requires that the connection points are placed "outdoors", but I'm looking for clarification regarding parking garages. We've got our main generator in a corner on the second floor of a parking garage, partially due to site space limitations and partially at the behest of the client. We'd like to put the quick connect just outside this room, effectively at a flat end of the parking ramp. This would allow a generator to be pulled up on a trailer and parked in a space that exhausts to the exterior. The garage has a perforated metal panel facade. Does this qualify as outdoors, or will we need to talk with the AHJ?

Perhaps the intent is to allow a ready connection for a temp generator on an emergency service?

I would say you are outdoors unless there are doors you have to go thru to leave the garage.

It sounds outdoors to me, too. Are any pics available?

It never hurts to ask whomever will be inspecting it.

NEC doesn't define outside, but the NFPA glosary of terms indicates Outside or Outdoor Installation:
A power system installation that is not located inside a building or that has only partial weather protection (maximum coverage of a roof and up to 50 percent enclosing walls).

I imagine there will be a chain-link gate at the entrance to the garage.

This connection point would be just up the ramp which enters off the street - the parking garage starts on the second level.


I think based on ron's NFPA definition, this might qualify as partial weather protection.
