Grounding; Electrical Lead Entry; Field-Connection Terminal Block - Kohler 14RESA Installation Manual

1.9.1

Grounding

Ground the generator set. The grounding method
must comply with NEC and local codes. Connect the
grounding cable to the generator set ground terminal
GND on the field-connection terminal block.
Generator sets are shipped with the generator neutral
bonded (connected) to the generator ground in the
junction box. The requirement for having a bonded
(grounded) neutral or ungrounded neutral is determined
by the type of installation. At installation, the neutral can
be grounded at the generator set or lifted from the
ground stud and isolated if the installation requires an
ungrounded neutral connection at the generator. The
generator set will operate properly with the neutral either
bonded to ground or isolated from ground at the
generator.
Various regulations and site configurations including the
National Electrical Code (NEC), local codes, and the
type of transfer switch used in the application determine
the grounding of the neutral at the generator. NEC
Section 250 is one example that has a very good
explanation of the neutral grounding requirements for
generators.

Field-Connection Terminal Block

The generator set is equipped with a field-connection
terminal block located in the air intake area near the
junction box. Leads have been factory-installed from
the junction box to the terminal block for easy field
wiring.
See Figure 1-17 for the terminal block location.
Remove the cover panel for access to the field
connections.
