Thanks for the help, very much appreciated. I did read thru Article 700 and saw that there are no special separation requirements. (occupancies under 75' and <1000 ppl)
See 700.10(C)&(D). Also exactly what loads are being served by the "emergency" panel?
The emerg. panel will supply the emergency egress lights in the common areas/corridors (and probably some tbd hvac loads)
This leads me to my next question..the dorm building is laid out such that there's essentially an apartment (bedrooms, kitchen, bathroom, own panelboard) and a more of a common boarding type area on the other side (many bedrooms, shared bathrooms, kitchen).
I know I def. need emerg. egress lights in the common boarding type area but should the segregated apartment unit also have emerg. egress lights?
