120V or 240V Three-Phase Delta

Three-phase delta installation measuring power coming from a power utility (grid). The color diagram below shows a 208V delta, but this also applies to a 120V delta or 240V delta.

Notes:
  •  CAUTION: Since there is no neutral and none of the phases may be grounded, all conductive/metallic parts, including CT-plug screws and CT wiring should be considered live and hazardous!
  •  If one of the phases is grounded, wire that phase to the Neutral (N) pin on the eGauge.
  • The eGauge inputs can measure up to 277V L-N terminal. A 600V delta must be measured the same way as a 480V Delta.
