GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or
breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock.
DANGER - IMPROPER CONNECTION OF THE
EQUIPMENT-GROUNDING CONDUCTOR CAN
RESULT IN A RISK OF ELECTROCUTION.
CHECK WITH A QUALIFIED ELECTRICIAN
OR SERVICE PERSON IF YOU ARE IN DOUBT
AS TO WHETHER THE UNIT IS PROPERLY
GROUNDED.
The wing nut and ground terminal on the frame must
always be used to connect the generator to a suitable
ground source. The ground path should be made with #8
size wire. Connect the terminal of the ground wire be-
tween the two star washers and wing nut then tighten the
wing nut fully. Connect the other end of the wire securely
to a suitable ground source.
The National Electric Code contains several practical
ways in which to establish a good ground source. Ex-
amples given below illustrate a few of the ways in which a
good ground source may be established.
A metal underground water pipe in direct contact with
the earth for at least 10 feet can be used as a ground-
ing source. If an pipe is unavailable, an 8 foot length of
pipe or rod may be used as the ground source. The pipe
should be 3/4 inch trade size or larger and the outer
surface must be noncorrosive. If a steel or iron rod is used
it should be at least 5/8 inch diameter and if a nonferrous
rod is used it should be at least 1/2 inch diameter and be
listed as material for grounding. Drive the rod or pipe to a
depth of 8 feet. If a rock bottom is encountered less than
4 feet down, bury the rod or pipe in a trench. All electrical
tools and appliances operated from this generator, must
be properly grounded by use of a third wire or be “Double
Insulated”.
It is recommended to:
1. Use electrical devices with 3 prong power cords.
2. Use an extension cord with a 3 hole receptacle and a 3
prong plug at the opposite ends to ensure continuity of
the ground protection from the generator to appliance.
We strongly recommend that all applicable federal, state
and local regulations relating to grounding specifications
be checked and followed.
LINE TRANSFER SWITCH
If this generator is used for standby service, it must have
a transfer switch between the utility power service and the
generator. The transfer switch not only prevents the utility
power form feeding into the generator, but is also prevents
the generator form feeding out into the utility company’s
lines. This is intended to protect the serviceman who may
be working on a damaged line.
THIS INSTALLATION MUST BE DONE BY A LICENSED
ELECTRICIAN AND ALL LOCAL CODES MUST BE
