Special Requirements for Other Occupancies

Other Special Issues for Healthcare Occupancies

There are many other special requirements in Article 517. One of the more significant ones is the requirement for an "essential electrical system" in some types of healthcare facilities – like hospitals.

Article 517: Part III: Essential Electrical System

The essential electrical system is covered by Part III of Article 517. It comprises features of an emergency system as well as a legally required standby system but is treated a little bit differently than in Articles 700 and 701.

The essential electrical system consists of an emergency system and an equipment system. The emergency system consists of a life safety branch and a critical branch. The life safety branch is most like the emergency system described in Article 700, where much of the system is used to help people out of a building in an emergency. In a hospital and some other facilities, the critical branch provides for critical patient care where evacuation or interruption of a procedure may be hazardous to the patient. The equipment branch supplies power to certain equipment that is necessary for continued use of the facility.
