Generator AC Connection System

A single-phase, three-wire AC connection system is used
in the home generator. The stator assembly consists of
a pair of stationary windings with two leads brought out
of each winding. The junction of leads 22 and 33 forms
the neutral lead, as shown schematically and as a wiring
diagram. A complete schematic and wiring diagram can be
found later in this manual.
