ANSI/NEMA C12 Series

Provides requirements and guidance on electricity metering, watthour meter sockets, device data tables, meter interfacing to data communication networks and type 2 optical ports. Also establishes performance criteria for thermal demand meters, mechanical demand registers and phase-shifting devices used in metering. Test methods for transformer-rated meters and self-contained A base watthour meters are included in this package, as is a watthour safety standard. The package contains all current parts of ANSI C12 (See Related Products Tab), as well as NEMA SG-AMI 1.
