Power Connections From Generator To Transfer Switch - GE 40350 Installation And Start-Up Manual

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.
Generator Power connection
for 8kW units: Using installer supplied minimum 300V, 90°,
10 AWG copper wire, or 300V, 90°, 8 AWG aluminum wire*,
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.
transfer switch communication
Using installer supplied #18 AWG twisted pair conductors, no
greater than 200 ft in length, connect Tx Rx and Tx Rx GND
from the generator terminal block
transfer switch control board

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.

for 10kW units: Using installer supplied minimum 300V, 90°,
8 AWG copper wire, or 300V, 90°, 6 AWG aluminum wire*,
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.
