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.  

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.

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
