3.3.1— Grounding Generator If Used as Portable
See Figure 3-6. An equipment ground connects the gen-
erator frame components to ground terminals on the AC
output receptacles. This allows the generator to be used
as a portable without grounding the frame as specified in
NEC 250.34.
3.3.1.1—Special Requirements
There may be Federal or State Occupational Safety and
Health Administration (OSHA) regulations, local codes,
or ordinances that apply to the intended use of the gener-
ator.
Consult a qualified electrician, electrical inspector, or the
local agency having jurisdiction:
•
In some areas, generators are required to be regis-
tered with local utility companies.
•
If the generator is used at a construction site, there
may be additional regulations which must be
observed.
3.3.2— Connecting to Building Electrical System
Use a manual transfer switch when connecting directly to
a building electrical system. Installation and connections
must be performed by a qualified electrician and in strict
compliance with all national and local electrical codes
and laws.
