Power connections from Generator to transfer switch
utility circuit connection
“240V Utility” leads must be routed in conduit. The “240V
Utility” leads deliver power to the generator’s circuit board,
optional battery warmer and optional oil warmer. This power
also charges the battery. When power on these leads is lost,
the generator will start.
Using installer-supplied minimum 300V, 14 AWG wire,
connect each control circuit terminal in the generator
(Utility A and Utility B) to the fuse block in the automatic
transfer switch.

Generator Power connection
Using installer supplied minimum 300V wires and the table
located on page 25, connect generator power output Line 1,
Line 2, neutral and ground to the corresponding Line 1, Line
2, neutral and ground in the transfer switch.
*Use National Electric Code for correction factors and wire
size calculations.
When making connections, obey wire type and torque
specifications printed on the circuit breaker and neutral/
ground connectors.
