Grounding the Generator When
In Use
The generator is equipped with an equipment
ground connecting the generator frame and
the ground terminals on the AC output recep-
tacles (see NEC 250.34 (A). This allows the
generator to be used as a portable without
grounding the frame of the generator as spec-
ified in NEC 250.34. See Figure 3-1.
• Neutral Floating
Figure 3-1.Grounding the Generator
The generator (stator winding) is isolated from
the frame and from the AC receptacle ground
pin. Electrical devices that require a grounded
receptacle pin connection will not function if
the receptacle ground pin is not functional.
Special Requirements
There may be Federal or State Occupational
Safety and Health Administration (OSHA) reg-
ulations, local codes, or ordinances that apply
to the intended use of the generator. Consult a
qualified electrician, electrical inspector, or the
local agency having jurisdiction:
• In some areas, generators are required to
be registered with local utility companies.
• If the generator is used at a construction
site, there may be additional regulations
which must be observed.
Connecting to a Building
Electrical System

ing directly to a building electrical system.
Installation and connections must be per-
formed by a qualified electrician and in strict
compliance with all national and local electri-
cal codes and laws.
Always operate the generator with the Eco
Mode Switch OFF (if equipped).
