GENERATOR FUNDAMENTALS

Figure 1-8. – Connection for 120 Volts Only

Reconnection for Dual Voltage Output:

When connected for dual voltage output, Stator output leads 11 and 44 form two “hot” leads (T1 – Red, and T3 – Black). The junction of leads 22 and 33 form the “Neutral” line (T2 – White).

For dual voltage output, the “Neutral” line remains grounded.

NOTE: For units with two 20 amp or two 30 amp main breakers, the existing breakers may be re- used when reconnecting for dual voltage output. However, on units with a 30 amp and a 20 amp main breaker, you may wish to install a 2-pole breaker that is rated closer to the unit’s rated capacity (use two 25 amp main breakers).

NOTE: If this generator has been reconnected for dual voltage AC output (120/240 volts), the replacement line breakers should consist of two separate breakers with a connecting piece between the breaker handles (so that both break- ers operate at the same time). If the unit is recon- nected for dual voltage, it is no longer RVIA listed.
