Three Phase
The connections for high and low voltage and delta are given in the following diagrams.The terminals must be connected securely and insulated with a good quality electrical tape.
Typical High Voltage (Series Wye) Connection (60 Hz)
Typical Low Voltage (Parallel Wye) Connection (60 Hz)
Typical Delta Connection (60 Hz)Single Phase Current From a Three-Phase Generator
Three phase and single phase current can be taken simultaneously from a generator connected for three phase service. Connecting the load to any two of the three phase leads in both Wye and Delta configurations will provide single phase voltage at the same voltage as three phase power. Connecting the load to any phase lead and neutral of the Wye configuration will produce voltage at 58% of three phase voltage. In the Delta configuration producing 240 volt 60 Hz three phase power, the high phase to neutral would produce 208 volts and either low phase to neutral would produce voltage at 120 volts of three phase voltage.Single phase power taken from a three phase source can be a problem unless the single phase loading is equally distributed.Do not exceed the nameplate current rating for any one phase.
