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.

transfer switch that is compatible with the generator.
