120/ 208V, 3 Wire, 2 Phases of a 3 Phase 120/208V
Three wir
es phase 1 live, phase 2 live, Grid 120V is live to neutral and 208 is phase
to phase. Assume unbalanced load. 2 CT Sensors
120/ 208V, 4 Wire, 3 Phases, Balanced Load
Three phase live, phase 2 live - Neutral, where 120V is phase to neutral and 208V
is phase to phase. 1 CT Sensor
120/ 208V, 4 Wire, 3 Phases, Unbalanced Load
The display does not recognize unbalanced loads in this configuration. The degr

Wire, 3 Phases, Balanced Load
Three phase live + neutral, where 277V is phase to neutral and 480V is phase to
phase. 1CT Sensor
277/ 480V, 4
Wire, 3 Phases, Unbalanced Load
Three phase live + neutral, where 277V is phase to neutral and 480V is phase to
phase. The display does not recognize unbalanced loads in this configuration.
The degree of accuracy will be
relative to the amount of unbalanced current.
