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 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.

Utility Circuit Connection

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.
*Use National Electric Code for correction factors and wire
size calculations.

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 output Line 1, Line 2, neutral and ground
in the transfer switch.
*Use National Electric Code for correction factors and wire
size calculations.
For 10kW units: Using installer supplied minimum 300V,
90°, 8 AWG copper wire, or 300V, 90°, 6 AWG aluminum
wire*, connect generator output 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 to T/R and GND on
the transfer switch control board. When making connections,
obey wire type and torque specifications printed on the
circuit breaker and neutral/ground connectors.
