4. GROUNDING.
a. Grounding of generators to earth is essential to place
the generator at earth potential, preventing hazards to
operators and draining static charges or stray current
harmlessly to earth. The generator neutral output terminal (LO)
is intentionally bonded to the generator grounding terminal on
its frame or chassis which is then connected to earth. No
current flows in the protective ground conductor unless there is
a fault.
b.
NEUTRAL IS NOT A GROUND ! It carries current when the
generator is supplying a load.
c. Generators are grounded to an Earth Ground System (EGS)
consisting of one or more rods connected in parallel. The EGS
resistance must be 10 ohms or less. The generator is connected
to the EGS using the shortest practical length of #6AWG copper
wire or larger. Ideally the conductor would be insulated, and
five feet or less in length to the nearest EGS.
d. Never attempt to start a generator set if it is not
properly grounded. Failure to observe this warning could result
in serious injury or death by electrocution.
e.
Connect Ground and Cable as Follows : (Refer to Table 2-2
on page 18.)
(1) Open Load terminal cover. Insert cable (1, Figure 2-
2) through slot on generator set GND load terminal (2). Tighten
terminal nut using wrench.
(2) Connect coupling (3) to ground rod (4) and screw
driving stud (5) into coupling. Make sure that driving stud
seats on ground rod.
(3) Drive ground rod (4) into ground until coupling (3)
is just above the ground surface.
(4) Remove driving stud (5) and install another section
of ground rod (4). Install another coupling (3) and driving
stud.
(5) Drive ground rod (4) down until new coupling (3) is
just above the ground surface.
