Prepare Generator for Use
Grounding the Generator When
Used as a Portable
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.
• Neutrals bonded to frame.
Figure 3-1. Grounding the Generator
Special Requirements
Review all 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 jurisdic-
tion:
• 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 the Generator to a
Building Electrical System
When connecting directly to a building electri-
cal system, it is recommended that a manual
transfer switch be used. Connections for a
portable generator to a building electrical sys-
tem must be made by a qualified electrician
and in strict compliance with all national and
local electrical codes and laws.
Know Generator Limits
Overloading a generator can result in damage
to the generator and connected electrical
devices. Observe the following to prevent
overload:
• Add up the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the gener-
ator's wattage capacity.
