are emergency lights connected to the circuit of lightings?

Question

is this possible or should there be an outlet for the emergency light?

Answer 1

It depends on what kinds of emergency lights you mean. The ones required and found in most commercial buildings, that will light up when the power goes off, are plugged in to keep the batteries charged. They detect that they are no longer receiving power, and then switch on. There is usually no backup generator involved for these.

Emergency lights connected to a backup generator may be connected to the normal circuits if the generator is designed to power all the circuits. If the generator is only designed to power certain circuits, then the lights may be plugged into those, or connected directly to the generator circuits. In hospitals you will often note colored (often red) outlets. These are the ones that will be powered by the emergency generators, so life-support equipment is plugged into these.

Answer 2

Depends on whether the emergency lights are on a battery backup or not. If the emergency lights are individually batt. backed up, then they very well could and should be wired to the same circuit as the normal lighting. If the emergency lights are NOT individually batt. backed up, then they will have their own independant circuit which is either more reliable or backed up by an external battery or generator.

Answer 3

If emergency lights are battery powered, they are usually connected to the building's electrical circuits, so as to keep the batteries charged. Emergency lighting would be useless, if the batteries are dead or weak.

However, if emergency lights are connected to a back-up power generator, they would be wired to the circuits that the generator controls.
