Definitions, service conditions, test procedures, and test conditions for faulted circuit indicators for use on power distribution systems are established in this test code.

This standard includes test codes which establish definitions, service conditions, test procedures, and test conditions for Faulted Circuit Indicators (FCIs) for use on power distribution systems.

FCIs are commonly used by electric utilities to aid in service restoration. The purpose of this standard is to identify the minimum various tests and test conditions that FCIs shall meet to validate their performance.
