Grounding the Generator
The home generator must be installed as part of a system
that includes a listed transfer switch, with neutral to
ground bonding at the transfer switch in accordance
with installation instructions. Unless mandated by local
code, additional grounding to earth at the generator is
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 [2.5 mm

wire, connect each control circuit terminal in the generator
(25 and 26) to the fuse block in the automatic transfer switch.

Generator Power Connection
For 8 and 10 kW Units:
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.
not required. Any grounding at generator must use metal
piercing lock washers (or equal), UL listed terminals installed
per terminal supplier’s instructions, and comply with national
electrical codes and local requirements.
