Single-Phase Current From a Three-Phase Generator
Three-phase current and single-phase current can be taken simultaneously from a generator that is connected for three-phase service. In the Wye Configuration, connect the load to the three-phase leads (any two of the three leads). In the Delta Configuration, connect the load to the three-phase leads (any two of the three leads). In both configurations, this configuration provides single-phase voltage at the same voltage as three-phase voltage.Connect the load to any phase lead and neutral lead of the Wye Configuration. This configuration will produce voltage at 58% of three-phase voltage.In the Delta Configuration that produces 240 Volts 60 Hz three-phase power, the voltages will be 208 Volts between the high phase and neutral and 240 Volts between either one of the low phases and neutral.Refer to Operation Section, "Generator Operation" for allowable single-phase loading unbalance.Single-phase power that is taken from a three-phase source can be a problem. Ensure that the single-phase loading is equally distributed.Do not exceed the nameplate current rating for any one phase.Wye Configuration Diagrams
