If Emergency Circuits are run outside (and if it matters this is for a Hospital), do they still need to be 2 hour rated?
This actually relates to a question I asked yesterday. I'm planning on running emergency circuits concrete encased underground from the main Emergency Electrical room over to Emergency Electrical rooms on the opposite side of this L shaped building. But on one end of this run, I need to come up the outside of the building several stories. For reasons I won't bore you with, I cannot run these feeders inside the building. I'm being told that Emergency circuits run in conduit and wire outside do not need to be rated. I don't see any verbage in the code supporting that however.
Can someone clarify this for me?
Thanks,
Mikie
