Grounding
The Generator must be properly grounded in
accordance with all relevant electrical codes and
standards before operation. In many locations, local
code will not require this generator to be grounded
when used with cord and plug equipment plugged
directly into the receptacles on the generator. However,
your local regulations may require the generator to be
grounded. Contact a licensed electrician or consult
local authorities regarding local grounding requirements.
If grounding is required, have the unit grounded by a
qualified electrician if you are not qualified to do so.
General grounding instructions are as follows:
Use one of the following as the grounding electrode:
pipe or conduit, minimum ¾ in. diameter, minimum
8 ft. long. If steel, it must have anti-corrosion coating.
Rod, stainless steel or copper- or zinc-coated steel,
minimum 5/8 in. diameter, minimum 8 ft. long.

1. Drive electrode at least 8 ft.
vertically into the ground.
a. If rock layer prevents vertical entry, drive at an
angle not exceeding 45 degrees from vertical.
b. If rock layer prevents angle entry, bury electrode
in horizontal trench at least 30 in. deep.
2. The upper end of electrode must be
protected if above ground level.
3. Connect a #6 AWG grounding wire (not included)
from the Grounding Terminal on the Generator
Control Panel to the buried electrode.
For additional information on grounding methods,
please see the National Electrical Code.
NOTICE: There is a permanent conductor
between the portable generator stator winding
