What specific requirements must emergency lighting systems follow according to Article 410?

Emergency lighting systems are crucial for ensuring safety during power outages or emergencies, which is why they are subject to specific requirements outlined in Article 410 of the National Electrical Code (NEC). These systems must adhere to essential criteria that span installation, testing, and maintenance.

The installation requirements ensure that emergency lighting is positioned correctly to provide adequate illumination during an emergency situation. This includes determining the appropriate locations, heights, and types of fixtures used to ensure that they operate effectively when needed.

Testing requirements are also vital; this ensures that the lighting systems are functioning correctly when an emergency arises. Regular testing helps identify any failures or issues before they become critical in an actual emergency.

Lastly, maintenance requirements are necessary to ensure the ongoing functionality and reliability of emergency lighting. Proper maintenance checks and schedules can prevent deterioration and ensure readiness when emergencies strike.

This comprehensive approach to installation, testing, and maintenance guarantees that emergency lighting systems can serve their lifesaving purpose efficiently.
