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).
