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.
