3.4 Grounding the Generator
The generator should be grounded to a good ground
source in compliance with National Electric Code stand-
ards and local regulations.
Use #8 wire and secure one end to the ground terminal
(a) provided on the generator frame and the other end to
a suitable ground source. See Figure 3-1.
3.5 Use of Extension Cords
When a long extension cord is used to connect an appliance or tool to the generator, a voltage loss occurs – the longer
the cord, the greater the voltage loss. This results in less voltage being supplied to the appliance or tool and increases
the amount of current draw or reduces performance. A heavier cord with a larger wire size will reduce the voltage loss.
Use Table 3-1 below as a guide for selecting proper cable size.
Use only extension cords rated for outdoor use and equipped with a third-wire ground.

Keep electrical cords in good condition. DO NOT use worn,
bare, or frayed cords which can cause electrical shock.
