What is the primary focus of NEC Article 700?

The primary focus of NEC Article 700 is on emergency systems, which are essential for maintaining electrical power during emergency conditions. These systems are designed to automatically provide power to critical loads when the normal electrical supply fails. Emergency systems include equipment like emergency lighting, exit signs, and systems that provide power to essential facilities such as hospitals and police stations, thus ensuring safety and operational continuity during power outages.

By concentrating on emergency systems, this article outlines the requirements for their design, installation, and maintenance, which is crucial in preventing hazards and ensuring that necessary power is available when it is most needed. This focus on emergency systems underlines the National Electrical Code's commitment to safety and reliability in electrical installations, particularly in life-safety scenarios.
