SIDEBAR: Power Source(s) for Electric Motor-Driven Fire Pumps
Section 695.3 is the most heavily revised portion of Art. 695 in the 2011 NEC. Three key revisions worth noting include:
- Feeders originating from a separate service (or a connection upstream of the service) are now addressed and permitted as a power source.
- The provisions for multiple sources have been expanded to address on-site standby generators and combinations of services and on-site generation. The use of a generator as an alternate source has also been addressed.
- Lastly, phase converters are now specifically prohibited as a power source for fire pumps.
