The NEMA Smart Meter Package provides the requirements and guidance on electricity metering, watt hour meter sockets, device data tables, meter interfacing to data communication networks and type 2 optical ports. NEMA Smart Meter Package 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 watt hour meter are included in this package as well as a watt hour safety standard. This package contains all parts of NEMA ANSI C12 and NEMA SG-AMI 1.
