NEC Article 700 specifically addresses emergency systems, which are vital for maintaining safety and operability during power outages or emergency situations. The article sets forth requirements for systems that are intended to provide backup power to essential services, including lighting, communication, and critical equipment. These emergency systems must comply with rigorous standards to ensure that they function reliably when needed most. This includes aspects such as installation practices, testing, and maintenance protocols.

The focus of NEC Article 700 is on ensuring that emergency systems are robust and fail-safe, driven by the critical nature of the services they support in emergencies. This level of scrutiny is less applicable to other types of installations, which might not require the same level of reliability under dire circumstances.
