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.
note: The portable generator Neutral conductor is isolated from the frame and from the
AC receptacle ground pin. Electrical devices that require a connection between one
conductor pin and the grounded receptacle pin may not function properly.
