Article 695 covers fire pumps. A lot of the information in this NEC article is extracted from NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection. That means there is an interplay between these two standards.

NFPA 20 addresses many aspects of the installation, but the specific details of the electrical wiring are for the most part left to the NEC. Article 695 also covers the control wiring for engine driven fire pumps. People wanting to install an electric fire pump should probably be looking at both standards.
