General Information
GENERATOR AC LEAD CONNECTIONS
See “Voltage Codes”. This generator may be rated at any one of three voltages, either
Voltage codes apply to the type of stator assembly installed on a particular generator.
FOUR-LEAD, SINGLE-PHASE STATOR
The rated voltage between each circuit breaker ter- minal is 240V. The rated voltage between each circuit breaker terminal and the neutral point 00 is 120V.

The generator is designed to supply
The rated voltage between circuit breaker terminals
The rated voltage between each circuit breaker termi- nal and the neutral point 00 is either 277V or 120V depending on the model.
