Normal power conduit go through emergency elec. room

[anbm]

Hospital has separate main normal power electrical room (contains main service elec. panel and distribution panels) and main emergency elec. room (contains all ATSs and emergency distribution panels only).

1) Can normal power conduits go through main emergency elec. room? These are not conduit feeding the ATSs.
2) Can a wireway or box be installed inside main emergency elec. room to intercept normal power conduit
(come from underground up inside the emergency elec. room) and then go to normal service room?

I think both are ok. Normal and emergency cannot share conduits, but their conduits can run side-by-side in either room.

Not an issue. If you think about something Iike an ATS it would have both normal and EM feeders run to it so they would have to be in the same room.

Thank you. I recalled somewhere in code says only conduits serving elevator equipment can be inside elevator machine room... This makes me wonder if same rule applies to N and E elec. rooms.

Not a problem at all for the emergency electric room. Assuming you are talking healthcare, a much larger concern is an IT room. No foreign systems can pass through unless they are serving the area. No feeders, branch circuits HVAC ducts plumbing etc.
