AC System Connections
The generator uses a single-phase, three-wire AC connection
system(Figure 13). The stator assembly consists of a pair
of stationary windings with two leads appearing from each
winding. The junction of leads 22 and 33 forms the neutral
lead.
NOTICE: Neutral is not bonded to ground at generator.
