Generator Output Balancing Autotransformer
Dual 120 Volt AC Loads
This configuration allows the 120/240 volt AC generator output to be
equally divided (balanced) between its L1 and L2 outputs. In this case, the
generator is using both its L1 and L2 outputs to supply two separate 120 volt
AC loads. If one leg of the generator is pulling a heavier load than the other,
both legs equally divide the current, thereby balancing the generators output.
Procedure
240 Volt AC Inputs From the Generator
 Connect the L1 (HOT) output of the generator to the terminal on the
lower breaker (point A).
 Connect the L2 (HOT) output of the generator to the terminal on the
upper breaker (point C).
 Connect the ground wire from the generator to the GROUND block in
the T240.
 Connect the neutral wire from the generator to the NEUTRAL block in
the T240.
120 Volt AC Outputs to Inverters or Loads
 Connect the 120 volt AC input wire for Inverter #1 to the service crimp
(point B) on the lower inverter.
 Connect the ground wire from the inverter #1 to the GROUND block
in the T240.
 Connect the neutral wire from Inverter #1 to the NEUTRAL block in
the T240.
 Connect the 120 volt AC input wire for Inverter #2 to the service crimp
(point D) on the upper inverter.
 Connect the ground wire from the inverter #2 to the GROUND block
in the T240.
 Connect the neutral wire from Inverter #1 to the NEUTRAL block in
the T240.
 Connect the inverters outputs as specified in the inverters operation
manual.
