For emergency lighting systems, a dedicated circuit using fire-resistant cabling, such as mineral-insulated copper-clad cable (MICC) or fire-rated twin and earth cable, is typically required to ensure reliable operation during a fire. The wiring must be installed according to local electrical codes, such as NFPA 70/NEC in the United States. These systems must provide a continuous, uninterrupted power supply, whether from a central battery unit or self-contained emergency luminaries, to ensure illumination and safe egress during power outages or emergencies.
