Re: NIGHT LIGHT/EMERGENCY FIXTURES
If you are using twin heads or emergency packs in the fixtures, article 700-12E wants them on the same circuit as the regular lights. If you have 3 or more circuits to a separate area, code allows a separate branch circuit for "unit equipment." If you have a generator and emergency circuits, then the wiring is separate (700.9B).

Re: NIGHT LIGHT/EMERGENCY FIXTURES
Not entirely sure what you are asking...but a night light and emergency light are two different luminaires, each requiring its own circuit. The emergency lighting has it's own seperate power source-generator or battery-which causes the luminaire to operate when normal-poco- power is lost. Night lights are often switchable.

Re: NIGHT LIGHT/EMERGENCY FIXTURES
The night lights, I assume, are the egress lighting required to remain on at all times the building is occupied. The emergency lights are the lights that come on if the power fails, to light the way out of the building. If there is no emergency generator, we have to use battery power to energize the egress lighting and exit signs. 700.12(E) covers "Unit Equipment", which is those battery packs with 2 headlights we use for emergency power. Their charging current is required to be connected to the circuit supplying lights in the area (ahead of the switches), unless there are 3 or more lighting circuits in the area.
Night lights used as egress lighting are covered by 700.16. Batteries, separate circuits or even separate panels are allowed to serve emergency night lights. If you use battery packs on your night lights, they become unit equipment, and are subject to 700.12(E).

Re: NIGHT LIGHT/EMERGENCY FIXTURES
We do this all the time in office buildings around here.
The fixtures that have been selected to be the emergency fixtures (supplied by the generator) are also the night lights.
Sometimes we even split feed the ballasts, 2 lamps on normal power, one lamp on emergency power. This is allowed by 700.9(B)(2)
Before I ramble on, :roll: are you asking about a building with an emergency generator or are you asking about fixtures with battery back up in them?

Re: NIGHT LIGHT/EMERGENCY FIXTURES
this is sleepy to add more to my question. these night lite fixtures and emergency/battery not generator. these fixtures are being installed in a small store. two/thirds of the fixtures are in areas that have 3 or more circuits. we have a couple of rooms where we put these nite/emergency fixtures. so now we have two circuits in these areas. i know to test these the inspector will shut off a breaker in the panel. there will always be lite. also, all the nite/emerg fixture are circuited together. good or no-good.

Here is part of 700.12(E)
Sounds like a no go to me.

And the exception to this.
