I am currently working on a project where we are employing the use of a programmable lighting controller. The lighting controller essentially consists of relays that are controlled by a microprocessor. We would like to use this controller to control the exterior egress lighting. Most of the lighting circuits are powered from a normal source however the egress lighting is powerered from an emergency power source. The wiring for the egress lighting would be routed to and from the enclosure in a separate conduit containing only emergency source conductors. They would only be combined with normal source wiring in the controller enclosure. Does this meet the intent of the code for separation of normal and emergency wiring? If not, would installing separation barriers in the enclosure work or would they have to be listed for that purpose?
In a separate but related question we have another project where we have normal and non-essential emergency receptacle circuits in temporary office partitions. We would like to utilize the modular wiring system associated with office partitions for both normal and non-essential emergency circuits. Would we be in violation of the NEC to do this?
