I am used to installing exit sign/emergency lighting unit combos. This time I must install an exit sign and an emergency light seperatly. Everything will be surface mounted using emt. I will be running emt from the panel to the exit sign and to a receptacle next to the lighting unit.The light unit will be plugged into it. Both will be on the same circuit and there will be nothing else in the conduit. My question is how do I supply the back up power(6VDC) from the emergency light unit to the exit sign? I want it to look nice. I don't think I can run 6Vdc in the same conduit as the 120VAC. Is the exit sign considered a remote device of the lighting unit in this case? If it is can I run the 6VDC in the same Conduit as the 120VAC if all conductors are insulated to the highest voltage rating? If not does anyone have any suggestions on how to wire it so it looks nice? Thanks
