Four-Lead Reconnectable (Single-Phase) Generator Sets Where Generator
Output Can Be Reconnected For 120 volt or 120/240 volt, 60 Hz,
When a generator set is reconnected to a voltage
different than nameplate voltage, notice should be
placed on the unit indicating this change. Decals for this
purpose are available
dealers/distributors.
120- or 110-Volt 3-Wire 2-Pole
Configuration--Figure 5-4
Jumper lead to be placed on line side of circuit breaker.
Leads L1 and L2 can either be left as separate leads or
can be connected together depending upon which is
practical for the given application. Regardless of the
number of phase (black) leads used in the application,
both circuit breakers must have leads attached to the
load side. It is recommended that jumper lead be
maintained for all straight 120- or 110-volt systems since
it helps balance the load of the generator set.

Figure 5-5. When connecting stator phase leads
together, the output lead (L1) must be sized accordingly.
