ANSI C12.1 Electric Meter Revenue Standard

WattNode Revenue models combined with class 0.6 current transformers meet the ANSI C12.1-2008 accuracy requirements. This includes the following part numbers:

  • RWNB-xx-xxx-P
  • RWNC-xx-xxx-BN
  • RWNC-xx-xxx-MB
  • RWNC-xx-xxx-FT10
Where ‘xx-xxx’ indicates the electrical service type and may be one of 3Y-208, 3Y-400, 3Y-480, 3Y-600, 3D-240, 3D-400, or 3D-480.

Furthermore, the following models of WattNode meter and Accu-CT current transformers—when used together—have been certified by MET Laboratories to the C12.1 standard.

  • RWNC-3Y-208-MB
  • RWNC-3Y-480-MB
  • RWNC-3D-240-MB
  • ACT-0750-100 Opt C0.6
  • ACT-0750-200 Opt C0.6



All WattNode meters meet FCC Part 15, Class B; EN 55022: 1994, Class B. Current transformers do not contain oscillators or active circuitry and so are exempt.
