Egress illumination must be provided with emergency power back up. I have a few points of confusion here.
1) Can I use a generator for emergency egress illumination?
NFPA 101 (7.?) sounds like the emergency egress illumniation must also come on if a breaker or fuse is tripped. The generator would not come on if the branch circuit breaker supplying the egress illumniation is tripped. So I'm not so sure that using a only generator would meet that requirement. I think I need stored engery back up(battery).
2) Whats the difference between an emergency and standby generator (either required or not)? I've heard that emergency generators require two fuel sources but so far haven't located that in any applicable codes.
3) If I can use a generator for egress illumination does it automatically become an "emergency" generator vs. a "standby"? Are there any ramifications to that.
A little background information. This is for an apartment complex. A generator has been requested. I'm not sure if its legally required or optional (I'm having trouble locating that in applicable codes as well). I was thiking of putting some of the normal lighting on a circuit that could be powered by the generator in case of a power failure. Then I came across the NFPA 101 requirement that egress illumination should be engaged if a breaker or fuse trips. So now I'm confused on whether I will need to have battery backup egress illumination as well.
