Understanding Control of Emergency Lighting Circuits ... For some time, the proper control of emergency lighting circuits has been a topic of debate for manufacturers, systems integrators, and specifying electrical engineers. Much of the debate has centered on the proper application of the many codes and standards that apply to emergency lighting. These include: Emergency Systems and the NEC | EC&M The branch circuit wiring that supplies IUE must be the same branch circuit wiring that supplies the normal lighting in the area. Don’t connect IUE to the emergency circuit. It won’t operate upon loss of normal power, because it will still have power. Connect the IUE ahead of any local switches.
