I have designed a lighting system with back up batteries in some of the flourescent fixtures for the emergency lighting. I feed all of these lights off of one lockable breaker. The plans reviewer says that 700.12E requires normal and emergency lights to be fed from the same circuit. Does the exception in 700.12F allow me to feed the lights off the same circuit. I'm not sure what the code means by "a separate and uninterruped area". This is for a retail store. The emergency fixtures are throughout the store. There are more than three lighting circuits that feed the store. Is the whole store "a separate and uninterrupted area"?
