Three Phase
The connections for both high and low voltage are given in the following chart.The terminals must be connected securely and insulated with a good quality electrical tape. 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 any two of the three phase leads will provide single phase current at the same voltage as three phase power. Connecting a three phase lead to neutral will produce current at 58% of the three phase voltage. DO NOT exceed the nameplate current rating for any one phase. Single Phase
When a generator is connected for single phase operation, do not exceed these limits:1. The nameplate amperage limits.2. Fifty-eight percent of the KVA and KW ratings. (The engine will only work about half as hard.)Three phase (230-460 V and 115-230V for SRCR) and (240-460V, 125-250 and 208-416 for SR 4) generators can be connected for two or three wire service at either voltage. When generators are connected for three wire service both high and low voltages may be obtained simulaneously without reconnecting the leads. In this case DO NOT ground TO. Generator neutral is not TO but a point in the windings electrically half way between T1 and T8. This point is not wired to a terminal.To reconnect the generator for single phase voltage follow the chart. Wrap all connections and unused terminals with a good grade of insulation.
