NFPA 855: Improving Energy Storage System Safety

While NFPA 855 is a standard and not a code, its provisions are enforced by NFPA 1, Fire Code, in which Chapter 52 outlines requirements, along with references to specific sections in NFPA 855.

How to meet short-circuit current rating requirements

The available short-circuit current must be determined prior to installation, and the equipment SCCR must not be less than the available short-circuit current. Eaton recommends implementing a
